transparency issue with display on Mac

Post by fmw42 »

This is still a problem on the Mac. Can someone verify this on a Mac? Is this behavior intentional?

IM 6.6.0-8 Q16 Mac OSX Tiger

Display of transparent png images --- the transparent part has no checkerboard and one can see through it to whatever window is behind it.

Image


display logo2t.png

Perhaps it might be better to have a checkerboard behind it as is currently done by using

convert logo2t.png show:

I tried

display -texture granite: logo2t.png

and

display -texture patterns:checkerboard logot2t.png

but the texture image did not show up for the background.

Also -texture no longer shows up as an option on http://www.imagemagick.org/script/display.php, but adding it as above does not cause an error or warning. It just does not add the texture.

Thanks.

Fred
