OK, one more question. I'm trying to come up with a patch for pecl-imagick. The feature was introduced in 6.9.9-28 and changed in 6.9.9-30.

6.9.9-28: sGRAYColorspace
6.9.9-30: LinearGRAYColorspace

How can I check the MagickLibVersion for these two versions? MagickLibVersion >= 0x699 won't cut it ...

Thanks! I found the responsible code.

ImageMagick 6.9.9-28:

typedef enum
{
UndefinedColorspace,
RGBColorspace, /* Linear RGB colorspace */
GRAYColorspace, /* greyscale (linear) image (faked 1 channel) */
TransparentColorspace,
[...]
HCLpColorspace,
YDbDrColorspace,
xyYColorspace ...

OK, so this is a breaking API change, right? What would be the correct course of action, now? Does pecl-imagick need to be adapted to include the new colorspace? Or is that simply a wrapper that exposes everything that is in the C library to PHP? And then Neos CMS needs to learn that COLORSPACE ...

Hi all,

I stumbled into an odd problem with a CMS written in PHP that uses pecl-imagick to scale images. After updating ImageMagick from 6.9.8-9 to 6.9.9-28 I get bogus colorspace values for a particular set of images.

I've come up with some PHP test code:


$imagick = new \Imagick(__DIR__.'/test ...
