PDF to image conversion question

[armagan]

When I convert a PDF file to PNG I get this rough edges all over the text. How can I convert it anti-aliased? I tried this command:

"convert -density 150 -colorspace RGB -units PixelPerInch a.pdf a.png"

You can see the screenshot of the actual PDF file and the result PNG:

Try a higher denisty, also read the image in first. I would also look at a quality setting http://www.imagemagick.org/script/comma ... hp#quality

Code: Select all

"convert -density 400 a.pdf -colorspace RGB -units PixelPerInch a.png"

Add -resize 25% if you want to reduce the final image size. Also investigate Ghostscript fonts. The default fonts are not the best and you will get better results if you provide commercial quality fonts to Ghostscript.

Higher density combined with resize did the trick, thanks a lot.

Another question: When I convert the pdf to gif it creates a single animated gif. How can I convert to separate gif files? I checked options page but couldn't see anything for this.

You can create separate image files with the +adjoin option or even better embed %02d in your filename:

• convert image.pdf image-%02d.gif

Thanks a lot, you rock.

Of course you
1/ Have to pay for it
2/ its is windows only!

If you are going to pay for a solution I would recommend going to Adobe, the owners of the Postscript and PDF file format. But I don't know what products they have for it.

too many post of commercial tools to convert PDF files to images recently on this forum!

Perhaps a post to the Kudos and Rants area is in order?

I don't mind hearing about alternative solutions, as long as it is only the once.
I would prefer free solutions though.

In the future, please do not tack on new questions to old topics. Also always provide your platform (as well as IM version, though you have that here).

Looks like a problem with your Ghostscript. Do you have it installed?
