PDFTOPPM -scale-to option
I'm using pdftoppm to convert PDFs to PNGs. I have played with the DPI options (-r, -rx, -ry) and increased the quality of the resultant images by increasing the DPI. I see that there is also a -scale-to option. I cannot quite figure our what it means though with
"Scales the long side of each page (width for landscape pages, height for portrait pages) to fit in scale-to pixels."
So, for example, if I use
-r 450
Then I have 450 by 450 pixels in the image. If I add
-scale-to 100
Will it now make the image something x 100 pixels? Or what pixels are being referred to in the scale-to option? Does it interact with -r at all? Or are they separate? Thanks.
