Hi, I would like to use transparnt colors in one of the documents. However the resulting color is different with transparent color. Could anyone try the following code twice setting the %-sign in front of the fill-statement: \setupoutput[pdftex] \starttext \setupcolors[state=start] \startuseMPgraphic{tBG} path p ; p := unitsquare xscaled \overlaywidth yscaled \overlayheight ; fill p withcolor \MPcolor{white}; % With normal colors, everything is fine (blue is really RGB(0,0,1) % fill p withcolor transparent("normal",.5,\MPcolor{white}); % This however results in fading of ALL of the colors... \stopuseMPgraphic \defineoverlay[textBG][\useMPgraphic{tBG}] \setupbackgrounds[page][background=color,backgroundcolor=blue] \setupbackgrounds[text][background=textBG] \input tufte \stoptext I would expect that the optical appearance of blue shoud not change after application of the transparent color to the gray areq. Regards Willi

Looks like an acrobat bug to me; if you use gsview, it works ok; there are more problems with acrobat and transparencies, like - no smoothing when a vector graphic is on top of a transparency - disappearing characters (esp very big ones) - funny flattener preview colors One of the reasons for such problems is that there is no 'reset graphics state' operator and i guess that occasionally the acrobat graphic state stack gets messed up.

Hi Hans, Indeed now I tried in Acrobat5 and the problem does not show up. There is probably another bug to be reported: I got a file, where with \startcombination ... \stopcombination two small pictures are placed next to each other. - When viewing the result in Acrobat6 everything looks ok. When printing the page, then the right picture will not show up on the print! Kind regards Willi At 10:37 25.11.2003, Hans wrote:

there are indeed some bugs with regard to xforms; you can try to print 'as image' Hans
Hoi Hans, Bedankt voor de link.... Het ziet er steeds gelikter uit. Op pagina 156 staat "Haas'sche Schriftgiesserei" Het apostroofje is vervangen door een kapitaal S-caron. - Dit is nogal raar omdat er op verschillende andere plekken in dit deel van het boek apostroven gebruikt worden. ?? Op pagina 164 laatste paragraaf: ... the single easiest way. - Ik denk, dat "single" weg kan. De "common consensus" > TeX Live is commonly seen as the most easiest way to get up and running a TeX system. Groet Willi At 13:10 25.11.2003, Hans wrote:
