Convert function - question

[tamtam]

Hello,

If I convert pdf file to jpg - How do the dimensions (width and height) set (without special options like -resize) ?
By which properties of the pdf file?

(code for example : convert test.pdf test.jpg)


Thanks!

You need to read in the pdf with -density. That controls the size of the output. PDF does not have any real size as it is vector format. Nominal size is 72 dpi.

convert -density xxx image.pdf image.jpg

or you can supersample

convert -density 288 image.pdf -resize 25% image.jpg
