Is there a program (PD or otherwise) that will take a postscript file and and convert it to EPS? For example, I would like to run a postscript graph from mathematica through it, and then include it as a \special in TeX. thanks. terry harrison hbx at psuvm.psu.edu

However, in the example cited, it's simple: run your Mathematica graph through psfix, which is supplied with the Mathematica package. Philip Machanick philip@pescadero.stanford.edu

I recall reading that a bitmap may optionally be included in the eps file. The bitmap is to be used to render the postscript figure by programs such as Frame. Does anyone know how to generate this bitmap? -- Hugh Fader hugh@slee01.srl.ford.com

The following is an extract from the Document Structuring Conventions v3.0 that might help. You can get the EPSF specification from our server (ps-file-server@adobe.COM). %%BeginPreview: <width> <height> <depth> <lines> <width> ::= <uint> /* Width of the preview in pixels */ <height> ::= <uint> /* Height of the preview in pixels */ <depth> ::= <uint> /* Number of bits of data per pixel */ <lines> ::= <uint> /* Number of lines in the preview */ %%EndPreview (no arguments) These comments bracket the preview section of an EPS file in Interchange format (EPSI). The EPSI format is preferred over other platform-dependent previews (for example, Apple Macintosh and IBM PC) when transferring EPS files between heterogenous platforms. The width and height field provide the number of image samples (pixels) for the preview. The depth field indicates how many bits of data are used to establish one sample pixel of the preview (typical values are 1, 2, 4, or 8). The lines field indicates how many lines of hexadecimal data are contained in the preview, so that an application disinterested in the preview can easily skip it. The preview consists of a bitmap image of the EPS file, as it would be rendered on the page by the print or PostScript language previewer. Applications that use the EPS file can then place the diagram in the including document. Each line of hexadecimal data should begin with a single percent sign. This makes the entire preview sectiona PostScript language comment so that the file can be send directly to the printer without modification. The EPSI preview should be placed after the %%EndComments in the document file, but before the defaults section (%%Begin(End)Defaults), if there is one, and before the prolog (%%BeginProlog) definitions. Note: Preview comments can be used only in documents that comply with the EPS file format. See "Encapsulated PostScript Files Specifications v3.0" for more details, including platform-specific versions of the preview. Carl 8-)

I'm cornfused. This eps thread and my past experience (limited) seems to imply that that an eps file should have as a minimum some postscript instructions in ascii, even if the included bitmap is not. However, I just purchased some (MS-DOS) T/Maker Professional EPS clip art. Arts and Letters has no problem converting them from EPS to their native format (so one assumes that they are "correct" eps format). However, when I tried printing them via UltraScript, it choked. When I did a "less" on the files, the file is all binary -- w/o any ascii postscript instructions?!?
