Changes in clipping path behavior?

Hi! I'm using ImageMagick as a library in my own Conversion-tool. I just updated from 6.5.2 to 6.7.1-0 and i noticed changes in how clipping paths would be handled. In the old version clipping paths would be applied automatically wheres i have to do it on my own now. Is that correct? How would I wri...

Re: switching colorspaces RGB -> YCbCr

I tried out the new version, but this still doesn't work. (see my introductory posting) this is due to the libjpeg which sets jpeg_color_space to JSC_YCbCr and out_color_space to JSC_RGB jdapimin.c: /* Guess the input colorspace, and set output colorspace accordingly. */ /* (Wish JPEG committee had ...

Re: ICC Colorprofile not read

i tried out the new 4.0.0 beta3 version of libtiff and it seems that they have fixed that problem.
maybe a that newer version schould be added to the windows source download and used for the precompiled binaries.
are there any known problems with newer libtiff versions?

thanks,
richard

Re: switching colorspaces RGB -> YCbCr

hi, i had a look at the sourcecode. I found a wrong statement in jpeg.c ReadJPEGImage 1020 if (jpeg_info.out_color_space == YCbCrColorspace) 1021 image->colorspace=YCbCrColorspace; since YCbCrColorSpace is a ImageMagick type and jpeg_info.out_color_space is a libjpeg type this I think this compariso...

Stack corruption in GetEXIFProperty function

Visual studio memory guard complained about corruption of the stack near variable 'buffer' I had a closer look a the code and figured out it was right: the macros EXIFMultipleValues and EXIFMultipleFractions do write on index -2 under some cirumstances: property.c 728 #define EXIFMultipleValues(size...

switching colorspaces RGB -> YCbCr

Hello!

When i try to convert a file to YCbCr its still RGB in the end (at least identify suggest it so)

Code: Select all

identify -verbose in.jpg
convert in.jpg -colorspace ycbcr out.jpg
identify -verbose out.jpg
Is this a bug or are RGB and YCbCr indistinguishable?

Thanks for comments.
regards,
richard

Re: Flatten changes color

why do you think this image isn't RGB? Either Photoshop and identify say the image's colorspace is RGB.

the weird change of the texcolor is also done if i only do:

Code: Select all

convert color.psd -flatten color.jpg
why is this so?
