Re: possible regression: unable to get the icc profile of an heic image under 7.0.8.44

thanks a lot @snibgo ! So as a conclusion, we can say : 1/ there is a regression in IM 6.0.8.44 as it's not possible anymore to find the ICC profile , so impossible anymore to convert the .heic file to jpg keeping the icc profile configuration (it's will be removed, but image stay in YCbCr color Spa...

Re: possible regression: unable to get the icc profile of an heic image under 7.0.8.44

@snibgo thanks a lot for this documentative answer! I still not understand one thing, how iphone devices (so quite a lot of users) can send image with YCbCr color space and sRGB color profile and as you say this is non-sense because an RGB profile can't be applied to YCbCr color space? but this work...

Re: possible regression: unable to get the icc profile of an heic image under 7.0.8.44

@snibgo little question, when I want to convert any image with any kind of icc profiles to a sRGB icc profile do I always need to first convert the image to sRGBColorspace color space and then later apply the icc sRGB color profile ? MagickTransformImageColorspace(sRGBColorspace) MagickProfileImage(...

Re: Imagemagick wand use only one single CPU

problem is that if you don't do fine tuning you can easily fall in situation where imagemagick will work very slowly, using only one CPU, or worse swaping between all cpu making operation very slow
