Hi,

I am using "ImageMagick-6.6.0-10-Q8-windows-dll" and have some problems loading PNG and TIFF files with 1-bit-per-pixel depths.

Here is a sample .png file that reproduces this error:
This .png file works perfectly in MS Paint, IrfanView, Windows Photo Gallery, etc.

When I run the command "imdisplay failed2.png" the image loads, but I get a weird display:

When I try to save to .jpg, an empty file is written.

When I try to run "convert failed2.png fixed.bmp" the same image displayed in IMDisplay is saved (the weird barred one) and no error is returned!
Graphicksmagick however works.

Any ideas as to why this is happening?

Thanks in advance!

We can reproduce the problem you posted and have a patch for ImageMagick 6.6.1-0 Beta available by sometime tomorrow. Thanks.

Thanks!

Should be OK in the SVN repo now. One-bit paletted PNG images were read incorrectly.

Thanks for the quickness!
