I did an experiment. 1. Untar IM 6.9.3-2 2. Untar delegate libraries which I want (zlib, lcms, openexr, xml, jpeg, png, tiff) to the IM 6.9.3-2 root folder. 3. Build delegates. 4. Install delegates to a custom folder like $HOME/3rdlibs/libs 5. Execute ./configure CXXFLAGS="-std=c++11 -mmacosx ...

Recently I downloaded IM 7.0.2-2. It was surprise for me when "configure" script was finished and I didn't see usual delegates like PNG, JPEG, TIFF. Usually, delegate libraries are installed to a custom folder. I use PKG_CONFIG_PATH variable to point to the delegate *.pc files. I don't use ports for ...

The workaround: to replace each '%' symbol by "%%" in a file path.

Hi. I have a problem with a file saving. When a file path contains something like this: "c:\tmp\%%\somefile.png" I catch an exception like this: "WriteBlob Failed `c:\tmp\%\somefile.png' @ error/png.c/MagickPNGErrorHandler/1630". I traced inside the library and found the problem here: blob.c lines ...

How do I workaround this behaviour?

I don't understand. Why is the same case in the IM "6,9,0,7" works as expected?

O, sorry I am wrong. The "convert.exe grayscale.png -profile sRGB.icc grayscale1.png" gives the wrong result as well.

But conversion to the srgb.icm works incorrect.
"convert.exe grayscale.png -profile srgb.icm grayscale1.png"
grayscale1.png is totally white.

"convert.exe grayscale.jpg -profile srgb.icm grayscale1.png"
grayscale1.png is expected result.

Thank you,
Snigbo.

The "convert.exe grayscale.png -profile sRGB.icc grayscale1.png" gives expected result.

I ran the "identify" utility for the grayscale.png. Result of color map looks weird. Perhaps it is not substantively:

png.txt
jpg.txt

Snigbo, Thank you. The problem is conversion from the grayscale.png. For other grayscale images everything works as expected. I have checked: grayscale.bmp grayscale.jpg grayscale.png grayscale.tif All works as I expected except the grayscale.png. I make conversion from all grayscale.* images to the ...

if I try to convert:
convert.exe grayscale.tif grayscale1.png
everything works as expected. But I get the same warning exception.

When I tried to make conversion from grayscale.png to grayscale1.png I get a warning message that looks like:
convert.exe: profile 'icc': 'GRAY': Gray color space not permitted on RGB PNG `g
rayscale1.png' @ warning/png.c/MagickPNGWarningHandler/1656.

And totally white grayscale1.png as result.

Glenn,
Thank you for the response. I think you right. Looks like a conversion problem.

Could someone to clarify this issue?
