eps(n)

Bestie, this is eps(n) from the BLT Built-In Commands page, and it's literally the manual for the Encapsulated PostScript canvas item. Canvas page-layout energy, preview images, titles, shadows — she does it all. Vibe check: passed. 💖

✨ NAME ✨

eps — Encapsulated PostScript canvas item.

---

🌸 SYNOPSIS 🌸

canvas create eps x y ?option value?...

🦋 DESCRIPTION 🦋

The eps canvas item lets you place encapsulated 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 you can use the canvas widget as a page layout tool. Slay. 💅

🎀 EXAMPLE 🎀

Let's say you have four 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. Honestly? Ate. ✨

💅 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.

✨ the valid option and value pairs ✨

• -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 of the 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 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. This 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 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 to a single space to display no title. The default is "".
• -titleanchor anchor — Tells how to position the title within the 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 of the EPS item. If pixels is 0, then the width is determined from the PostScript "BoundingBox:" entry in the EPS file. The default is 0. Also, the source page has a stray 5i. sitting right here, so it stays: 5i. 💀

Sign-off time: this page is from BLT, version 2.5, and it's the eps(n) manual. The footer doesn't list a date, so we're not inventing one — no cap, periodt. 💅✨🫶
