On Windows 8.1, downloaded from
http://www.imagemagick.org/download/bin ... static.exe .
The default format for output filetypes seems broken. For example, the following produce binary-identical files, all in the PPM compressed format.
Code: Select all
%IMG6901%convert rose: rose.png
%IMG6901%convert rose: rose.jpg
%IMG6901%convert rose: rose.tiff
%IMG6901%convert rose: rose.gif
%IMG6901%convert rose: rose.exr
A workaround is to use a prefix, eg
Code: Select all
%IMG6901%convert rose: PNG:rose.png

I see the same thing on my Mac OSX Snow Leopard with IM 6.9.0.1PPM It seems to keep whatever is the input format rather than use the output image's suffix to change formats. jpg png png JPEG

I've had something like this happen as well, I had to change my scripts on Linux to prefix the format.

As this has broken a fundamental feature of IM, you might consider re-releasing 6.9.0-1 or scheduling a rapid release of 6.9.0-2.

Thanks for fixing this, after trying to debug my scripts to no avail, this is a good incentive to visit the IM forum
... I couldn't imagine for this basic fault, actually IM itself is to blame. Probably some regression testing suite to avoid something like this would be in order, or extending the beta testing period of new versions?

We added a unit test for this mistake I made
The patch was created right before the release.
