Dear list, (especially Luigi)
for online publication I need to create a PDF/A compliant output file. Does anyone have any experience with it and can tell me whether my setup will work? So far I'm using
\setupbackend [ format={pdf/a-2a}, profile={default_cmyk.icc,default_rgb.icc,default_gray.icc}, ] \setupstructure[state=start,method=auto]
I chose PDF/A-2a because there I can have PDF 1.7 which keeps the file size down but I can also switch to PDF/A-1a. I have *no* external pixel graphics, just included PDFs which are also produced by ConTeXt with the same setup.
Online I found Luigi's paper on PDF/A-1a [1]. However, even after reading I'm unsure whether `intent` is optional or required.
Since I don't own Adobe Acrobat (nor am I using Windows) I cannot verify the resulting output. Does anyone know any working free or open-source tools for GNU/Linux to do this task? Have a look at http://verapdf.org/software/ and test the file below with $> verapdf -v -x -f 1a test.pdf It should be ok
The icc files default_cmyk.icc default_gray.icc default_rgb.icc are from ghostscript, put them in the same directory of the test. \nopdfcompression \setupinteraction [title=TITLE, subtitle=SUBTITLE, author=AUTHOR, keyword={{KEYWORD1, KEYWORD2}, KEYWORD3}] %% For PDF/A \setupbackend[ format={pdf/a-1a:2005}, % or pdf/a-1a:2005 profile={default_cmyk.icc,default_rgb.icc,default_gray.icc}, intent=ISO coated v2 300\letterpercent\space (ECI)] %% Tagged PDF %% method=auto ==> default tags by Adobe \setupbackend[export=yes] \setupstructure[state=start,method=auto] \startchapter[title=Testing] \startcolor[red] \input knuth \stopcolor \input tufte \input knuth \placefigure[middle][fig:foo] {This is an image} {\externalfigure[cow.jpg]} \input tufte \stopchapter \stoptext I'm in a middle of something else now, I will look into it next days, but you can play a bit and report problems. -- luigi
