aliase problem when converting PostScript images

[donovaly]

I'm using Ghostscript 8.62 and ImageMagick 4.6.1-1.

When I convert this file:
http://fkurth.de/uwest/bugreports/test2.eps
with the command

Code: Select all

convert test2.eps test2.jpg

I get this result:
http://fkurth.de/uwest/bugreports/test2.jpg
You can see that the image gets aliased.

But when I convert it to PNG instead of JPG, it the image is correctly converted without being aliased:
http://fkurth.de/uwest/bugreports/test2.png

Not a bug. Its an artifact of converting an image with an alpha channel (test2.eps) to one that does not support transparency (test.jpg). To get the results you desire, use

• convert test2.eps -flatten test2.jpg

even better

• convert -density 400 test2.eps -resize 25% -flatten -quality 90 test2.jpg

Many thanks for the prompt reply. This was indeed my problem.
