Dear Debian-Science, Here was a discussion about software used to make a graphs for publications. Among others the R statistical software was mentioned. I spent some time to learn it and found a problem when tried to submit an eps graphs created with R. The publisher (AIP) demands submission of separate eps file for each figure with all fonts embedded in it (even the standard 14 adobe fonts). As I understand the R does not do this embedding. It inserts only comments what resources are needed.
There was a discussion on the R Help list: http://tolstoy.newcastle.edu.au/R/help/05/01/10749.html#10751qlink1 Salients points were: 1) some publishers do accept EPS files that refer to the Adobe base 13 fonts via DS comments of the form: %%DocumentNeededResources: font Times-Roman %%+ font Times-Bold %%+ font Times-Italic %%+ font Times-BoldItalic %%+ font Symbol This needs some care, as the majority of systems will substitute free fonts such as the URW versions for the real Adobe fonts. Unfortunately, there are some differences that can be significant -- compare, e.g., Helvetica-Oblique with Arial-Italic. Ghostscript now provides a ps2ps2 script that supports the Adobe distiller parameters, so you should be able to configure it to embed the fonts, but the result is plain (level 2) PS and not EPS and does not have DSC. This is similar to what you would get by converting to PDF and back to PS. 2) some proprietary programs (Corel Draw) do provide an option to embed fonts in EPS files.
Is there a solution for problem within open source environment (without using of proprietary software)?
My approach is to convert fonts to outline paths, in part because in the good old days many typesetters used 3rd party rasterizers that could not reliably render all Type 1 fonts, in particular, the Y&Y/BSR versions of Computer Modern. This does mean you loose the benefits of font hinting, which affects low-res devices (<400dpi, e.g.,screen viewing), but does not matter at photo-typesetter resolutions (>1000 dpi). This can be done using the pstoedit tool with "-f ps2ai -dt ..." Try this on a trivial file: .../texmf/doc/latex/graphics/a.ps and open the eps file in an editor. You should see a bunch of lines ending in "c", defined in the prologue as "rcurveto", used to draw the outline of the letter. The ps2edit utility can also be used to do this. If you use the ps2ai driver you can load the results in sketch/skencil see the outline paths. I sometimes use this to create annotations for figures.
The second picture format that AIP journals accept is TIFF, but R has no tiff device to produce that pictures. Is there a strait way to convert the EPS file into the high resolution high quality TIFF figure?
The problem with TIFF has been the non-free status of the LZW compression method. I think the patent has lapsed in some jursidictions, so perhaps effective compression is available in current tools such as Image Magick.
Sorry if this is off-top questions.
Not at all, as the problem involves using tools available to debian users to do things that are commonly done using commercial tools. -- George N.
