DISCONTINUED!!! Win32 GDI graphical printing If You are desperate to find me You can try to to do it through CPAN!
1. Make sure you have a C/C++ compiler and you're running Win32.
2. For VC++ 6.0 or VC++ .NET do the following (others not tested):
> perl Makefile.PL > nmake > nmake test > nmake install
3. For bitmap support, copy FreeImage.dll somewhere in your system path. You may get this library form http://sourceforge.net.
4. For PDF support, install Ghostscript and set path to it's \bin directory. You may get this PostScript interpreter form http://sourceforge.net.
5. For Barcode support, install ebbl. DISCONTINUED!!!
6. Enjoy it ;)
All symbolic constants are exported by default!!!
new Win32::Printer ( [ parameter => value, ... ] );
The new class method creates printer object, starts new document (a print job), returns printer object and changes $dc->{flags} variable. $dc->{flags} contains modified printer dialog flags. new also sets $dc->{copies}, $dc->{collate}, $dc->{maxp} and $dc->{minp}, $dc->{xres}, $dc->{yres}, $dc->{xsize}, $dc->{ysize} variables.
$dc->{xres}; # X resolution
$dc->{yres}; # Y resolution
$dc->{xsize}; # X size in chosen units
$dc->{ysize}; # Y size in chosen units
NOTE! Print job is automatically aborted if print job is not ended by End or Close methods or if an error occurs!
The new class method sets the following optional printer object and document parameters:
Specifies whether collation should be used when printing multiple copies. This member can be be one of the following values:
0 - Do not collate when printing multiple copies. 1 - Collate when printing multiple copies (default).
Using collate provides faster, more efficient output for collation, since the data is sent to the device driver just once, no matter how many copies are required. The printer is told to simply print the page again. If this flag is set to 1 and print dialog is used, the Collate check box is initially checked.
$dc->{collate} variable shows if collation was required. You may use it after print dialog to check user input.
If $dc->{collate} is set to 0 - You need to handle multiple copies by yourself.
See also copies.
Switches between color and monochrome on color printers. Following are the possible values:
MONOCHROME = 1 COLOR = 2
Initial number of document copies to print. Used by dialog and/or printer driver. $dc->{collate} variable shows how many copies were required.
See also collate.
If dc defined- returns only device context without starting the document and new page.
Set to:
0 - default; 1 - die on warnings; 2 - warn on errors (not recomended);
If debug level set to 2- methods return undef value on error.
MAY INTERFERE WITH DIFFERENT PRINTER OBJECTS!
See also Debug.
Document description. Default is ``Printer''. It is used as document name, filename suggestion and/or PDF document title;
If both printer and dialog attributes omitted- systems default printer is used.
Printer dialog settings. You may use the combination of the following flags ($dc->{flags} contains modified printer dialog flags):
ALLPAGES = 0x000000
The default flag that indicates that the All radio button is initially selected. This flag is used as a placeholder to indicate that the PAGENUMS and SELECTION flags are not specified.
SELECTION = 0x000001
If this flag is set, the Selection radio button is selected. If neither PAGENUMS nor SELECTION is set, the All radio button is selected.
PAGENUMS = 0x000002
If this flag is set, the Pages radio button is selected. If this flag is set when the new method returns, the $dc->{maxp} and $dc->{minp} variables indicate the starting and ending pages specified by the user.
NOSELECTION = 0x000004
Disables the Selection radio button.
NOPAGENUMS = 0x000008
Disables the Pages radio button and the associated edit controls.

PRINTSETUP = 0x000040
Causes the system to display the Print Setup dialog box rather than the Print dialog box.
NOWARNING = 0x000080
Prevents the warning message from being displayed when there is no default printer.
DISABLEPRINTTOFILE = 0x080000
Disables the Print to File check box.

Set file attribute to save printer drivers output into the file specified by value of attribute. Note: Specified file will not be overwritten- it's name will be changed to file_name(1)... file_name(n) to avoid overwriting.
If the flag is set - End(), Abort() and Close() methods returns possibly
modified file name.
See also pdf, prompt, End, Abort and Close.

The Polybezier method draws cubic Bézier curves by using the endpoints and control points specified by the @points array. The first curve is drawn from the first point to the fourth point by using the second and third points as control points. Each subsequent curve in the sequence needs exactly three more points: the ending point of the previous curve is used as the starting point, the next two points in the sequence are control points, and the third is the ending point. The current point is not updated.
See also BezierTo.

$char_num = $dc->Fit($text, $maxwidth, [UTF8]); ($char_num, $width, $height) = $dc->Fit($text, $maxwidth, [UTF8]);
The Fit method retrieves the number of characters ($char_num) in a specified string ($text) that will fit within a specified space ($maxwidth) and in array context also returns $width, $height of string. Use UTF8 for UTF-8 encoded strings;
$font_handle = $dc->Font([$face, [$size, [$angle, [$charset]]]]); ($font_handle, $previous_font) = $dc->Font([$face, [$size, [\[$escapement, [orientation]\], [$charset]]]]);
or
$dc->Font($font_handle);
The Font method creates and selects a logical font that has specific characteristics and returns handle to it or selects given font by it's handle. Fontsize is set in pts. In array context also returns previously selecte font handle.
For UTF-8 support see Write.
IMPORTANT!!! First font (e.g. ``Arial'') that matches desired attributes is selected if desired font is not found. Reason of that may be raster font, wrong font name, character set unsupported by font etc. Warning is issued!
If $angle is array reference then function looks for ($escapement, [orientation])
Example:
$fh = $dc->Font("Arial", 10, [-90, 0]); # Same as:
$fh = $dc->Font("Arial", 10, [-90]); # ...prints characters cascaded vertically
$escapement - Specifies the angle in degrees, between the escapement vector and the x-axis of the device. The escapement vector is parallel to the base line of a row of text.
Windows NT/2k/XP/...: You can specify the escapement angle of the string independently of the orientation angle of the string's characters.
Windows 95/98/Me: The $escapement member specifies both the escapement and orientation. You should set $escapement and $orientation to the same value.
$orientation - Specifies the angle, in degrees, between each character's base line and the x-axis of the device.
Defaults to:
$face = ''; # First font (e.g. "Arial") that matches desired attributes $size = 10; # fontsize $angle = 0; # text direction angle in degrees $charset = DEFAULT; # character set code
$face may include any combination of the following attributes: bold italic underline strike.
Defined character set constants:
ANSI = 0 DEFAULT = 1 SYMBOL = 2 MAC = 77 SHIFTJIS = 128 HANGEUL = 129 JOHAB = 130 GB2312 = 134 CHINESEBIG5 = 136 GREEK = 161 TURKISH = 162 VIETNAMESE = 163 HEBREW = 177 ARABIC = 178 BALTIC = 186 RUSSIAN = 204 THAI = 222 EASTEUROPE = 238 OEM = 255
See also FontEnum, Write, Color and EBbl.
$font_table = $dc->FontEnum([$face, [$charset]]); @font_array = $dc->FontEnum([$face, [$charset]]);
The FontEnum method enumerates all fonts in the system available for printer that match the font characteristics specified. It returns tab-delimited table of values in scalar context or array of hashes in array context. $font - font face of interest, $charset - character set of interest.
Follown hash keys available:
{Face} - enumerated font face
{Charset} - enumerated character set (character set codes - see Font method)
{Style} - enumerated font style ('bold' and/or 'italic')
{Type} - type of enumerated font face (Raster = 1, Device = 2, TrueType = 4);
See also Font.
$old_space = $dc->FontSpace($space);
The FontSpace function sets the intercharacter spacing ($space) and returns previous value. $space is in pts. Intercharacter spacing is added to each character, including break characters, when the system writes a line of text.
$image_handle = $dc->Image($filename); ($image_handle, $original_width, $original_height) = $dc->Image($filename);
or
$image_handle = $dc->Image($filename, $x, $y, [$width, $height]); ($image_handle, $original_width, $original_height) = $dc->Image($filename, $x, $y, [$width, $height]); $dc->Image($image_handle, $x, $y, [$width, $height]);
or
($width, $height) = $dc->Image($image_handle);
The Image method loads an image file into memory and returns a handle to it or draws it by it's filename or handle. $x, $y specifies coordinates of the image upper-left corner. $width, $height specifies the width and height of image on the paper (default is set by image header). Once loaded by image path- image is cached in to memory and it may be referenced by it's path.
In second case if signed integer is given- method assumes it's a handle!
In array context also returns original image width an d height $original_width, $original_height.
Natively it supports EMF and WMF format files. BMP, CUT, DDS, ICO, JPEG, JNG, KOALA, LBM, IFF, MNG, PBM, PBMRAW, PCD, PCX, PGM, PGMRAW, PNG, PPM, PPMRAW, PSD, RAS, TARGA, TIFF, WBMP, XBM, XPM bitmap formats are handled via FreeImage library.
Image file formats are recognized by their extensions. On failure- method tries to recognize it by file content (bitmaps only).
WARNING! Metafiles may have objects outside the bounding box specified by metafile header. These objects will be visible unless you specify clipping region (See PClip).
After usage, you should use Close to unload image from memory and destroy a handle.
See also Close, MetaEnd and EBbl.
$dc->ImageSave($handle, $filename, [$bpp, [$width, $height, [$format, [$flag]]]]);
The ImageSave method saves image as bitmap by its $handle aquired by Image, MetaEnd or EBbl methods. $filename represents the file name and path string. $bpp for setting target bit depth (currently only 24-bit & 8-bit images supported). $width, $height target width of the image.

$dc->Inject($point, $page, $data);
The Inject method adds $data to a specific $point in specified $page.
Where $point specifies where to inject the raw data in the PostScript output. This member can be one of the following values. $page specifies the page number (starting from 1) to which the injection data is applied. Specify zero to apply the injection data to all pages. This member is meaningful only for page level injection points starting from PSI_PAGENUMBER. For other injection points, set PageNumber to zero.
The injection data for a specified injection point is cumulative. In other words, Inject method adds the new injection data to any injection data previously specified for the same injection point.
If the job is in EMF data type, you must provide all injection data before Start.
If the job is in RAW data type, you must provide the following injection data before the driver needs it:
1) Data for header sections (before first %%Page:) before calling the first Page method.
2) Data for page setup sections (when injecting data for one particular page) before calling the Page method for that particular page.
3) Data for page setup sections (when injecting data for all pages starting from a certain page) before calling Page for the starting page.
4) Data for page trailer sections before calling the next Page method.
5) Data for document trailer sections before calling the Close method.
The injection points are:

$dc->LineTo(@endpoints);
The LineTo method draws a series of line segments by connecting the points in the specified array. The current point is updated.
See also Line.
$filename2 = $dc->Meta([$filename1], [$width, $height]);
The Meta method opens an EMF bracket. This means that everything until MetaEnd will be drawn in to the EMF file. Device context is based on current Printer object device context, but only default objects and their default values are selected into it.
$filename2 - name of the EMF file to create (if omited or empty - creates only memory EMF file). $width, $height - width and height of the EMF file.
Function returns possibly changed filename.
Use ``FILE:'' or ``FILE:C:/suggest.emf'' as a file name to invoke 'Save as' dialog.
Function will not overwrite existing files but will change names like file, except if set by dialog (this is different from file).
You may not use nested brackets!
See also MetaEnd.
$image_handle = $dc->MetaEnd(); ($image_handle, $width, $height) = $dc->MetaEnd();
The MetaEnd method closes an EMF bracket and returns handle to a creted EMF image and also $width, $height in array context. After usage, you should use Close to unload image from memory and destroy a handle.
See also Meta, Image and Close.
($old_x, $old_y) = $dc->Move($x, $y);
The Move method updates the current position to the specified point.
See also ArcTo, LineTo and BezierTo.
$dc->Next([$description]);
The Next method ends and starts new print job. Equivalent for:
$dc->End(); $dc->Start([$description]);
Default description - ``Printer''. Method returns possibly changed file name if file attribute is set.
Inside Meta brackets:
($image_handle ,$filename2) = $dc->Next(([$filename1], [$width, $height]);
In this context - closes previous and opens new Meta brackets. If arguments omited - uses arguments from previous brackets.
See also Start, End, Abort, Page, Meta and MetaEnd.
$dc->Page();
The Page method starts new page.
Not allowed in Meta brackets!
$dc->PAbort();

CR_AND = 1
The new clipping region includes the intersection (overlapping areas) of the current clipping region and the current path.
CR_OR = 2
The new clipping region includes the union (combined areas) of the current clipping region and the current path.
CR_XOR = 3
The new clipping region includes the union of the current clipping region and the current path but without the overlapping areas.

CR_COPY = 5
The new clipping region is the current path.
See also PBegin, PDraw, PEnd and PAbort.
$dc->PDraw();
The PDraw method closes any open figures in a path, strokes the outline of the path by using the current pen, and fills its interior by using the current brush and fill mode.
See also PBegin, PClip, PEnd, PAbort and Fill.
$dc->PEnd();
The PEnd method closes a path bracket and selects the path defined by the bracket.
See also PBegin, PClip, PDraw and PAbort.

The Pen method creates a logical pen that has the specified style, width, and color. The pen can subsequently be used to draw lines and curves. Pen width is set in pts regardless of unit* attribute in new constructor or whatever is set by Unit method. Using dashed or dotted styles will set the pen width to 1 px! If no parameters specified, creates transparent pen.
You may use the following pen styles:

The pie is outlined by using the current pen and filled by using the current brush. $x, $y sets the upper-left corner coordinates of bounding rectangle. $width, $height sets the width and height of bounding rectangle. $start_angle, $end_angle2 sets the starting and ending angle of the pie according to the center of bounding rectangle.
See also Ellipse, Chord, Arc and ArcTo.
$dc->Poly(@vertices);
The Poly method draws a polygon consisting of two or more vertices connected by straight lines. The polygon is outlined by using the current pen and filled by using the current brush and polygon fill mode.
$dc->Rect($x, $y, $width, $height, [$ellipse_width, $ellipse_height]);
The Rect method draws a rectangle or rounded rectangle. The rectangle is outlined by using the current pen and filled by using the current brush. $x, $y sets the upper-left corner coordinates of rectangle. $width, $height sets the width and height of rectangle. Optional parameters $ellipse_width, $ellipse_height sets the width and height of ellipse used to draw rounded corners.
See also Poly.
$dc->Space($eM11, $eM12, $eM21, $eM22, $eDx, $eDy);
The Space method sets a two-dimensional linear transformation between world space and page space. This transformation can be used to scale, rotate, shear, or translate graphics output. Transformation on the next page is reset to default. Default page origin is upper-left corner, x from left to right and y from top to bottom.
0 ------- x | | | y
For any coordinates (x, y) in world space, the transformed coordinates in page space (x', y') can be determined by the following algorithm:
x' = x * eM11 + y * eM21 + eDx, y' = x * eM12 + y * eM22 + eDy,
where the transformation matrix is represented by the following:
| eM11 eM12 0 | | eM21 eM22 0 | | eDx eDy 1 |
$dc->Start([$description]);
The Start method starts a print job. Default description - ``Printer''.
NOTE! Print job is automatically aborted if print job is not ended by End or Close methods or if an error occurs!
Not allowed in Meta brackets!
See also Next, End, Abort and Page.
$dc->Unit([$unit]);
The Unit method sets or gets current unit ratio.
Specified unit is used for all coordinates and sizes, except for font sizes and pen widths.
You may use strings:
'in' - inches 'mm' - millimeters 'cm' - centimeters 'pt' - points (in / 72)
Or unit ratio according to:
ratio = in / unit
Example: 2.5409836 cm = 1 in
Set units to 0 to use device units.

# String mode (SM): $height = $dc->Write($text, $x, $y, [$format, [$just_width]]); ($width, $height) = $dc->Write($text, $x, $y, [$format, [$just_width]]);
# Draw mode (DM): $height = $dc->Write($text, $x, $y, $width, $height, [$format, [$tab_stop]]); ($width, $height, $length, $text) = $dc->Write($text, $x, $y, $width, $height, [$format, [$tab_stop]]);
SM: The Write method string mode writes a character string at the specified location, using the currently selected font, text color and alignment.
DM: The Write method draw mode draws formatted text in the specified rectangle. In array context method returns array containing ($width, $height, $length, $text). $height is returned in scalar context. $length receives the number of characters processed by Write, including white-space characters. See CALCRECT and MODIFYSTRING flags. Optional $tab_stop parameter specifies the number of average character widths per tab stop.
Warning! - $widt must be less than 0x80000000 units.
Optional text format flags:
UTF8 = 0x20000000 (SM & DM)
Treat $text as UTF-8 encoded string. Note that selected font must support desired unicode characters. Available for NT platforms and also supported by Microsoft Layer for Unicode.
NOUPDATECP = 0x00000000 (SM)
The current position is not updated after each text output call. The reference point is passed to the text output method.
TOP = 0x00000000 (SM & DM)
SM: The reference point will be on the top edge of the bounding rectangle.
DM: Top justifies text. This value must be combined with SINGLELINE.
LEFT = 0x00000000 (SM & DM)
SL: The reference point will be on the left edge of the bounding rectangle.
ML: Aligns text to the left.
UPDATECP = 0x00000001 (SM)
The current position is updated after each text output call. The current position is used as the reference point.
RIGHT = 0x00000002 (SM & DM)
SL: The reference point will be on the right edge of the bounding rectangle.
ML: Aligns text to the right.
VCENTER = 0x00000004 (DM)
Centers text vertically (single line only).
BOTTOM = 0x00000008 (SM & DM)
SL: The reference point will be on the bottom edge of the bounding rectangle.
ML: Justifies the text to the bottom of the rectangle. This value must be combined with SINGLELINE.
WORDBREAK = 0x00000010 (DM)
Breaks words. Lines are automatically broken between words if a word extends past the edge of the specified rectangle. A carriage return-linefeed sequence also breaks the line.
BASELINE = 0x00000018 (SM)
The reference point will be on the base line of the text.
SINGLELINE = 0x00000020 (DM)
Displays text on a single line only. Carriage returns and linefeeds do not break the line.
EXPANDTABS = 0x00000040 (DM)
Expands tab characters. Number of characters per tab is eight.
NOCLIP = 0x00000100 (DM)
Draws without clipping. Write is somewhat faster when NOCLIP is used.
EXTERNALLEADING = 0x00000200 (DM)
Includes the font external leading in line height. Normally, external leading is not included in the height of a line of text.
CALCRECT = 0x00000400 (DM)
Determines the $width and $height of the rectangle. If there are multiple lines of text, Write uses the width of the given rectangle and extends the base of the rectangle to bound the last line of text. If there is only one line of text, Write modifies the width of the rectangle so that it bounds the last character in the line. In either case, Write returns the height of the formatted text, but does not draw the text.
INTERNAL = 0x00001000 (DM)
Uses the system font to calculate text metrics.
EDITCONTROL = 0x00002000 (DM)
Duplicates the text-displaying characteristics of a multiline edit control. Specifically, the average character width is calculated in the same manner as for an edit control, and the method does not display a partially visible last line.
PATH_ELLIPSIS = 0x00004000 (DM) END_ELLIPSIS = 0x00008000 (DM)
Replaces part of the given string with ellipses, if necessary, so that the result fits in the specified rectangle. The $text element of returning array is not modified unless the MODIFYSTRING flag is specified.
You can specify END_ELLIPSIS to replace characters at the end of the string, or PATH_ELLIPSIS to replace characters in the middle of the string. If the string contains backslash (\) characters, PATH_ELLIPSIS preserves as much as possible of the text after the last backslash.
MODIFYSTRING = 0x00010000 (DM)
Modifies the $text element of returning array to match the displayed text. This flag has no effect unless the END_ELLIPSIS, PATH_ELLIPSIS or WORD_ELLIPSIS flag is specified.
RTLREADING = 0x00020000 (SM & DM)
Layout in right to left reading order for bi-directional text when the selected font is a Hebrew or Arabic font. The default reading order for all text is left to right.
WORD_ELLIPSIS = 0x00040000 (DM)
Truncates text that does not fit in the rectangle and adds ellipses.
CENTER = 0x00080000 (SM & DM)
SL: The reference point will be aligned horizontally with the center of the bounding rectangle.
ML: Centers text horizontally in the rectangle.
JUSTIFY = 0x80000000 (SM)
Extends space characters to match given justification width ($just_width).
Note: Allways use $just_width parameter with JUSTIFY flag!
See also Font, Fit, Color, FontSpace and Write2.
$height = $dc->Write2($text, $x, $y, $w, [$flags, [$indento, [$hspace, [$vspace]]]]); ($width, $height, $proctext) = $dc->Write2($text, $x, $y, $w, [$flags, [$indent, [$hspace, [$vspace]]]]);
The Write2 method adds multiline justification, custom vertical and horisontal spacing and left indent; Returns $height in scalar context and $width, $height, $proctext where $proctext is possibly modified text (e.g. added line breaks).
Reasonable only when justification, left indent, custom vertical and/or horizontal spacing is needed, othervise consider to use regular Write method.
LEFT = 0x00000000
Aligns text to the left.
RIGHT = 0x00000002
Aligns text to the right.
CENTER = 0x00080000
Centers text horizontally in the rectangle.
JUSTIFY = 0x80000000
Extends space characters to match given width.
