Re: scanned paper pdfs and original image extraction.

I used:

Code: Select all

convert -density 300 mypdf.pdf output.png
After trying -density 600 mypdf.pdf -resize 50% it seems to work better. These shouldn't give the exact same image right? The -density 600 and -resize 50% are resampling at a greater quality. Is that correct? Thanks.

There are many images like it that have 1-5 words on it with the same pixel dimensions. Do they need to be larger? It is only 43 pixels tall.

Thanks.

scanned paper pdfs and original image extraction.

Pixel wizards of open source. I summon thee! Although my mortal quarrels are surely nothing to your dances with the four elements, I seek you to lift my troubles.

Re: Pdf conversion is losing graphics and text

Thanks. I was using file.pdf[1] (which I edited to show in my first post to avoid further confusion) when I should have used file.pdf[0].

Pdf conversion is losing graphics and text

Hello. I just recently moved to using ImageMagick to automate pdf conversions. I am running into trouble with convert missing some graphics from the original.
