AFAIK it compresses the text objects. 9 is maximum

Suppose this situation: me and you agree on a context beta version and a pdf reader and you send me your tex file with 1) a png/jpeg image or a pdf file as externalfigure. Then my pdf and your pdf must be the same, and on average the reader will show the same result. Otherwise probably is a bug. 2) a swf. Then my pdf and your pdf must be the same, but probably the reader will not show the same result -- basically only acroread is able to show swf inside a pdf, and it depends to the OS and version 3) a svg image. PDF spec. doesn't support SVG, so we must also agree on the same program to convert the svg into a bitmap or vector image, and this is a problem: as you have seen, the conversion require a bit of experience. After all, it's not strange if inkscape 0.40 and 0.48 display the same svg in different way --- and the same for the pdfs. Actually, only an expert user can use inkscape to automatically convert an svg to pdf/png without (appreciable) errors, and this kind of user is also able to install the correct version of inkscape (which is much easier to install under windows then linux,btw). So, if you are creating a svg by tourself, it's better to check that the pdf and png are the same if you want to be sure that your image will be printed/display correctly --- there aren't so many programs that completely support the svg standard. ConTeXt then helps this kind of expert user because they are able a priori to understand if a svg image is problematic or not . -- luigi ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
Re: [NTG-context] \externalfigure and file size
On Debian Packages, at least, we can declare, basically, 3 levels of dependencies, according to http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps 1) Depends - absolute dependency. Or else, packages that is strictly necessary to works well. 2) Recommends - strong, but not absolute dependency. 3) Suggests - used to declare that one package may be more useful with one or more others. So, I think Inkscape would fit well as 'context' Suggests. -- Wagner Macedo On 20 January 2012 21:54, Hans Hagen pra...@wxs.nl wrote: no, because not all users use svg (just an not all users use fonts defined in type-* files) and also because inkscape is close to impossible to install without x present which would render context 'unuseable due to a depency not being resolved' ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

The reason for this is I find some vector images get enormously bloated when they are typeset. As an example, I have a Logo.svg of only 6.8 KB. The m_k_i_v_Logo.pdf intermediate ConTeXt generates is nearly a megabyte in size. Why? I have no idea, as they both appear to be the same image with the same gausian blur. If original svg image is 7 KB, the PDF should not be any bigger apart from the header and maybe embded fonts. However if you are using some smooth shading, it might be that the program which does the conversion is performing a poor job and converts shading into hundreds of thin strips of different colors. I would try to use a different tool for conversion into PDF (not into raster image, but into vector image) before running ConTeXt. I don't know which one, but you can try to experiment.
