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?

Hi, i use this command to convert pdf files to image files convert -density 600x600 -units pixelsperinch input -background white -alpha background -alpha off -scene 1 -resize 50% -compress jpeg +adjoin output but thats extremely slow compared to the windows tool PDFXChange Viewer that i used so far ...

What is the different? you use %w and %h instead of %W. but i cant see any other different.

Hi, because of a Bug in IM 6.x (https://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=33455) i tried to install IM 7.x on my Ubuntu 16.04. That worked good, but i can't decode my PDF because of missing Delegates (PNG). I searched on the Web and found some Pages. I have to compile IM with ...

OK, this will fix the problem with the wrong output names. But there is still the problem with the missing leading zeros when original pdf has more then 10 or 100 pages. is there a solution? the same with the wrong resolution in the output name? or can i calculate this directly in the command ...

Hi, i use this script to convert pdf files into several images files: convert -density 300x300 -units pixelsperinch input.pdf -background white -alpha background -alpha off -resize 25% -compress jpeg +adjoin -set filename:mysize '%s_%G' "output_%[filename:mysize].tif" IM writes the width and the ...

but how can i create a new one? i dont understand whats written in "command line option".

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.

yes, its right. but normally when i use normal output convert creates numbers after the filename, like output1.tif output2.tif. this doesn't work when i use the output with image size in the file name. when i try this convert -density 300x300 -units pixelsperinch input.pdf -background white -alpha ...

Hi, i use this command line to convert multi image pdfs into single files: convert -density 300x300 -units pixelsperinch input -background white -alpha background -alpha off -antialias -compress zip +adjoin output.tiff then i tried to add some information into the output filename as i could read ...

The same bad results.

Result is the same with +adjoin convert -density 200x200 -units pixelsperinch input.pdf -background White -layers flatten -compress zip +adjoin output.tiff But alos without '-alpha off' the result isn't very good when i zoom in the output tiff. For that i tried this command line convert -density ...

This creates one tiff file with all sites of the pdf document in that one tiff.
