Re: [Texmacs-dev] [TeXmacs] New experimental Pdf export facility

[Massimiliano Gubinelli]

Handling of images is a problematic issue. To embed images in PDF we need to convert them to PDF before, at the moment I use ImageMagik since it is an easy way to do.  I would like to discuss more deeply the handling of images in TeXmacs. We rely on various methods and it is quite confusing to me. I think we should settle down to some standard way of doing, independent of platform if possible. Our requirements are the following:

The graphic backend needs a bitmap for the image.

The ps backend needs a eps file for the image.

The pdf backend needs a pdf file for the image.

How to proceed to support the largest number of image format in reliable way? For example if I have a jpg image I would like to retain the compression in the pdf and in the eps. 

Can we rely on Qt?

Should we ship ImageMagik and Ghostscript by default to support these conversions?

Should we try to convert the formats to EPS by hand and then use GS to convert them to PDF?

I’m a bit lost.

Hi,

  it looks great! The support for the table of contents is awesome too. Two comments:

* The unanounced hard dependency on ImageMagick confused me for a while. A small warning would've helped. See the attached demo patch.

* Link targets seem to be set to the baseline of the line where the target is. This has as a consequence that one has to scroll one line after clicking a link to see the actual section/theorem/whatever pointed to. (Preview on MacOS 10.9)

Thanks for all the work.

Best,

Dear all,

We are happy to announce a native Pdf export facility written by Massimiliano.
In order to try it, you should compile TeXmacs from the source code as follows:

    ./configure --enable-pdf-renderer
    make
    etc.

Any feedback is welcome, as well as bug reports.
When reporting a bug, please send us a sample document and
provide the necessary information about your OS and Pdf viewer.

As soon as the facility will be sufficiently stable,
it will become our default way to produce Pdf files.

Best wishes, --Joris
