Error when converting lots in JPG in BATCH

[mikarts]

Sorry. I haven't been able to update the libjpeg delegate. Could you tell me how please? Or maybe where can I see how to do it? Thank you.

It would be helpful if you provide your IM version and platform (assumed Windows from you title). Did you install IM from binary or source.

I have the problem till a few versions ago. The first was 6.7 I think.
I have installed Windows Binary Releases always.
First I worked under Windows 7 Professional, and now with the Windows 10 platform.
Now I have tried the versions:
- ImageMagick-7.0.7-28-Q16-x64-dll.exe
- ImageMagick-7.0.7-28-Q16-x64-static.exe
- ImageMagick-7.0.7-28-Q8-x64-static.exe

What is the version of libjpeg on your new system? You can find out from

Code: Select all

magick.exe -list format

then look at the line for JPG. On my Mac OSX with IM 7.0.7-28 Q16, I get:

JPG* JPEG rw- Joint Photographic Experts Group JFIF format (90)

I do not think there is a more current version than 9 (90). See https://github.com/LuaDist/libjpeg and https://en.wikipedia.org/wiki/Libjpeg

Your binary should include libjpeg 90.
