I have custom workflow which generates web enabled renditions for images,even for png also it generates like cq5.web.1024.666.png ,but i want it like cq5.web.1024.666.jpg. I am not sure its proper way or not.
If it is PNG image then, are we suppose to use only thumbnail rendition?
Simply configure the Web Enabled Rendition Process step in the Update Dam Asset workflow to be something like:
dimension:1280:1280,mimetype:image/jpeg,quality:90,skip:application/pdf,skip:audio/mpeg,skip:video/(.*)
Adjust values as appropriate.
