NAME
eps - Encapsulated PostScript canvas item.
SYNOPSIS
canvas create eps x y ?option value?...
_________________________________________________________________
DESCRIPTION
The eps canvas item lets you place encapulated PostScript (EPS) on a canvas, controlling
its size and placement. The EPS item is displayed either as a solid rectangle or a
preview image. The preview image is designated in one of two ways: 1) the EPS file
contains an ASCII hexidecimal preview, or 2) a Tk photo image. When the canvas generates
PostScript output, the EPS will be inserted with the proper translation and scaling to
match that of the EPS item. So can use the canvas widget as a page layout tool.
EXAMPLE
Let's say you have for PostScript files of four graphs which you want to tile two-by-two
on a single page. Maybe you'd like to annotate the graphs by putting a caption at the
bottom of each graph.
Normally, you would have to resort to an external tool or write your own PostScript
program. The eps canvas item lets you do this through Tk's canvas widget. An eps item
displays an image (or rectangle) representing the encapsulated PostScript file. It also
scales and translates the EPS file when the canvas is printed.
SYNTAX
canvas create eps x y ?option value?... The eps item creates a new canvas item. Canvas is
the name of a canvas widget. You must supply the X-Y coordinate of the new eps item. How
the coordinate is exactly interpreted is controlled by the -anchor option (see below).
Additional options may be specified on the command line to configure aspects of the eps
item such as its color, stipple, and font. The following option and value pairs are
valid.
-anchor anchor
Tells how to position the EPS item relative to its X-Y coordinate. The default is
center.
-background color
Sets the background color of the EPS rectangle.
-borderwidth pixels
Sets the width of the 3-D border around the outside edge of the item. The -relief
option determines if the border is to be drawn. The default is 0.
-file fileName
Specifies the name of the EPS file. The first line of an EPS file must start with
"%!PS" and contain a "EPS" version specification. The other requirement is that
there be a "%%BoundingBox:" entry which contains four integers representing the
lower-left and upper-right coordinates of the area bounding the EPS. The default
is "".
-font fontName
Specifies the font of the title. The default is *-Helvetica-Bold-R-
Normal-*-18-180-*.
-foreground color
Specifies the foreground color of the EPS rectangle. The option matters only when
the -stipple option is set. The default is white.
-height pixels
Specifies the height EPS item. If pixels is 0, then the height is determined from
the PostScript "BoundingBox:" entry in the EPS file. The default is 0.
-image photo
Specifies the name of a Tk photo image to be displayed as in the item as a preview
image. This option overrides any preview specification found in the EPS file. The
default is "".
-justify justify
Specifies how the title should be justified. This matters only when the title
contains more than one line of text. Justify must be left, right, or center. The
default is center.
-relief relief
Specifies the 3-D effect for the EPS item. Relief specifies how the item should
appear relative to canvas; for example, raised means the item should appear to
protrude. The default is flat.
-shadowcolor color
Specifies the color of the drop shadow used for the title. The option with the
-shadowoffset option control how the title's drop shadow appears. The default is
grey.
-shadowoffset pixels
Specifies the offset of the drop shadow from the title's text. If pixels is 0, no
shadow will be seen. The default is 0.
-showimage boolean
Indicates whether to display the image preview (if one exists), or a simple
rectangle. The default is yes.
-stipple bitmap
Specifies a bitmap to used to stipple the rectangle representing the EPS item. The
default is "".
-title string
Sets the title of the EPS item. If string is "", then the title specified by the
PostScript "Title:" entry is used. You can set the string a single space to
display no title. The default is "".
-titleanchor anchor
Tells how to position the title within EPS item. The default is n.
-titlecolor color
Specifies the color of the title. The default is white.
-titlerotate degrees
Sets the rotation of the title. Degrees is a real number representing the angle of
rotation. The title is first rotated in space and then placed according to the
-titleanchor position. The default rotation is 0.0.
-width pixels
Specifies the width EPS item. If pixels is 0, then the width is determined from
the PostScript "BoundingBox:" entry in the EPS file. The default is 0. 5i.
