PsDocument class

This class encapsulates PS/EPS documents.

Inheritance: PsDocument → Document

The PsDocument type exposes the following members:

Constructors

Constructor	Description
init	Initializes empty `PsDocument` with initialized page.
init	Initializes empty `PsDocument`.
init	Initializes empty `PsDocument` when the number of Postscript document pages is known in advance.
init	Initializes `PsDocument` with a stream of PS/EPS file.

Properties

Property	Description
number_of_pages	Returns the number of pages in resulting PDF document.

Methods

Method	Description
save	Saves PS/EPS file to a device.
save	Saves given `PsDocument` as EPS file. This method is used only after updating XMP metadata. It saves initial EPS file with updated existing metadata or new one created while calling GetMetadata method. In the last case all necessary PostScript code and EPS comments are added.
save	Saves given `PsDocument` as EPS file. This method is used only when PsDocument was created from scratch.
save_image_as_eps	Saves PNG/JPEG/TIFF/BMP/GIF/EMF image from input stream to EPS output stream.
save_image_as_eps	Saves PNG/JPEG/TIFF/BMP/GIF/EMF image from file to EPS file.
save_image_as_eps	Saves Bitmap object to EPS file.
save_image_as_eps	Saves Bitmap object to EPS output stream.
open_page	Creates new page and make it current one.
open_page	Creates new page with document’s size and make it current one.
rotate	Adds rotation counterclockwise about the origin to current graphics state (rotate current matrix).
rotate	Adds rotation counterclockwise about the origin to current graphics state (rotate current matrix).
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
fill_text	Adds a text string by filling interrior of glyphs.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
outline_text	Adds a text string by drawing glyphs contours.
fill_and_stroke_text	Adds a text string by filling interrior of glyphs and drawing glyphs contours.
fill_and_stroke_text	Adds a text string by filling interrior of glyphs and drawing glyphs contours.
fill_and_stroke_text	Adds a text string by filling interrior of glyphs and drawing glyphs contours.
fill_and_stroke_text	Adds a text string by filling interrior of glyphs and drawing glyphs contours.
draw_polyline	Draws a polyline.
draw_polyline	Draws a polyline.
draw_polygon	Draws a polygon.
draw_polygon	Draws a poligone.
fill_polygon	Fills a poligone.
fill_polygon	Fills a poligone.
draw_image	Draw image.
draw_image	Draw transformed image with background.
get_xmp_metadata	Reads PS/EPS file and extracts XmpMetdata if it already exists or add new one if it doesn’t exist.
extract_eps_size	Reads EPS file and extracts a size of EPS image from %%BoundingBox comment or default page size (595, 842) if it doesn’t exist.
resize_eps	Resizes given `PsDocument` as EPS file. This method is used only after extracting EPS size. It saves initial EPS file with updated existing %%BoundingBox or new one will be created. Page transformation matrix also will be set.
extract_eps_bounding_box	Reads EPS file and extracts bounding box of EPS image from %%BoundingBox comment or bounds for default page size (0, 0, 595, 842) if it doesn’t exist.
crop_eps	Crops given `PsDocument` as EPS file. It saves initial EPS file with updated existing %%BoundingBox or new one will be created.
set_page_size	Sets page size. To create pages with different sizes in one document use PsDocument.SetPageDevice method just after this method.
close_page	Complete current page.
write_graphics_save	Writes saving of the current graphics state (See PostScript specification on operator “gsave”).
write_graphics_restore	Writes restoring of the current graphics state (See PostScript specification on operator “grestore”).
set_transform	Set current transformation to this one.
transform	Adds transformation to current graphics state (concatenates this matrix with current one).
translate	Adds translation to current graphics state (translates current matrix).
scale	Adds scale to current graphics state (scale current matrix).
shear	Adds shear transformation to current graphics state (shear current matrix).
clip	Adds clip to current graphics state.
clip_text	Adds clip from an outline of given text in given font.
clip_rectangle	Adds clipping rectangle to current graphics state.
clip_and_new_path	Adds clip to current graphics state and than writes “newpath” operator. It is necessary to do to escape of confluence of this clipping path and some subsequent pathes such as glyphs outlined with “charpath” operator.
set_paint	Sets paint in current graphics state.
get_paint	Gets paint of current graphics state.
set_stroke	Sets stroke in current graphics state.
get_stroke	Gets stroke of current graphics state.
fill	Fill an arbitrary path.
draw	Draw an arbitrary path.
draw_arc	Draws an arc.
draw_line	Draws a line segment.
draw_oval	Draws an oval.
draw_rect	Draws a rectangle.
draw_round_rect	Draws a round rectangle.
fill_arc	Fills an arc.
fill_oval	Fills an oval.
fill_rect	Fills a rectangle.
fill_round_rect	Fills a round rectangle.
draw_transparent_image	Draw transformed transparent image. If image doesn’t have Alpha channel it will be drawn as opaque image
draw_explicit_image_mask	Draw masked image.
merge	Merges PS/EPS files to a device.
