I am using IM 6.4.0-2-Q16 to convert and bild jpgs for Illustrator and Photoshop files uploaded to a directory on my server. On alot of photoshop files I get a bizarre preview image. The image has white squares or sometimes garbled lines in place of where the image goes. The files are quite often very large that it is building the image from. Others i build just fine. I suspect it has something to do with transparency or effects applied to layers. I am flattening the image and converting to rgb to try and resolve the issue
This is an example image
This is the high res file 89 megs

Convert """&Whichfolder&"\"&filename&""" -strip -profile USWebCoatedSWOP.icc -profile sRGB.icc -flatten -thumbnail 250 """&FilePath&"\thumbnails\"&newname&
Previous:
