Anyone have insight on this problem with image resolution in version 7?
SetDirectory@NotebookDirectory[];
plot = Plot[x, {x, 0, 10}];
Export["plot.gif",plot,ImageSize->5*72,ImageResolution->300]
The export command seems to ignore ImageResolution.
Here is what used to work in V5.2 of Mathematica:
Export["plot.gif",plot,ImageResolution->300]
This "plot.gif" in V7 now has the problem that all of the ticks and so forth
have become very small, i.e., they were not scaled properly. Apparently,
Mathematica combined ImageSize and ImageResolution by scaling the image to
(300/72)*5*72, without proportionate magnification of the ticks. [This was
not a problem in earlier versions of Mathematica, e.g., V5.2.]
Here is a messy workaround:
Export["plot.gif", Magnify[Show[FullGraphics@plot, Options[plot,
AspectRatio]], 300/72],ImageResolution -> 300]
My question for the group: Am I missing a simple solution to this problem
instead of the messy work around?
Thanks for any help and insight!
