Re: Convert PDF to Images without transparent background

Thanks, this works for the most PDF-Files i've tried. But there is one PDF that i can't extract. The resulting Images consists of transparent background only - that means there is no text or something in the image and also no white background. This is the Command line i've tried: convert -density 30...

Re: Convert PDF to Images without transparent background

PDF files are vector files that may contain a raster image. OK, i didn't know this. But i can try what i want (density 300x300 or higher), the output quality is extremly poor. you can try it with this document. density doesn't improve the output quality. Other Tools like PDF-XChange Viewer (Windows...

Re: Convert PDF to Images without transparent background

Doesn't work. I set density to 1200 before the import, but the output quality is poor. when i zoom in the resulting image the edges are not plain. the resolution of the output is very small, it only 597x842px. i think this is the problem. i don't know the resolution of the image in the pdf. how can ...

Re: Convert PDF to Images without transparent background

i converted 2 pdf files to images, one with convert, one with pdfxchangeviewer. the first is 3000x2000px as the original, the second is 500x400. how can i keep the input resolution for each image (each site of the pdf). i don't want to set up this manually because every pdf file is different.

Re: Convert PDF to Images without transparent background

seems density is the same option like 'dpi' in other applications? in pdfxchange viewer (that i used on windows to export images from a pdf file) i can set up x-dpi and y-dpi (both 300). whats that in imagemagick?
