			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 6.9.0.1 
 
 
convert rose: rose.png 
identify -verbose rose.png 
Image: rose.png 
  Format: PPM   (Portable pixmap format (color)) 
 
 
It seems to keep whatever is the input format rather than use the output image's suffix to change formats.  
 
convert lena33.jpg   tmp.png  
identify tmp.png  
tmp.png JPEG   512x512 512x512+0+0 8-bit sRGB 76.2KB 0.000u 0:00.000

			I've had something like this happen as well, I had to change my scripts on Linux to prefix the format.  
Then I got three segfaults I can't reproduce. *smh*

			We can reproduce the problem you posted and have a patch in ImageMagick 6.9.0-2 Beta, available by sometime tomorrow.  Thanks.

			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.
