Hi, Inspired by a question about animated gif I tried to build some my own, but without success: << Graphics`Animation` gr = Animate[ Plot[Sin[x t], {x, -\[Pi], \[Pi]}, PlotRange -> {-1, 1}], {t, 0, 1}] Export["gr.gif", gr,"GIF"] gives the error message Export::"type": "\!\(Null\) cannot be exported to the \!\(\"GIF\"\) format." Let's try a single picture: gr2 = Plot[Sin[x], {x, -Pi, Pi}] Export["gr.gif", gr2] gives a black gif picture. On the other hand Export["gr.eps", gr2] works fine. A more successful way to get a GIF image is: Display["gr.gif", gr2, "GIF"] The online help says ?Display Display[channel, expr,"format\"] writes boxes, cells or notebook expressions in the specified format." ?Export Export[\"file\", expr, \"format\"] exports data to a file, converting it to the specified format." So, the calling sequence is similar, but only the latter case worked for me. What am I doing wrong here, and moreover how do I get the animated gif? (I am working with Mathematica 4.0 under Linux) Thanks for your help, Wolfgang ======================================================================== Wolfgang Schadow Phone: +1-604-222-1047 ext. 6453 (office) TRIUMF +1-604-875-6066 (home) Theory Group FAX: +1-604-222-1074 4004 Wesbrook Mall Vancouver, B.C.
