Re: Convert from PDF to Image very slow

It depends on the size of your PDFs: the number of pages, and the pixels per page.

this is clear, but other tools working faster with the same pdf. maybe they are working different? can i change this when using IM?

Re: Convert multi image PDF in single files with image size in title

i use version 6.8.9.9 on ubuntu 16.04.
I think it would need a new -define to be created to tell IM that scene numbers should have leading zeros or a new string format.
what do you mean? i read the command line options but didn't understand ow i can do this with -define.
