github: https://github.com/iStumblerLabs/pdf2png
usage: pdf2png -i <input.pdf> [-o <output-file-prefix>] [-s @,@2x,50,100x50,100@2x,400%]
[-t ios|android-small|macos-small|android-large|ios-small|macos|ios-large|android|macos-large|retina]
[-A Resources/Catalog.xcassets]
-i — input file name, a PDF document
-o — output file prefix, to which the size and .png will be appended
-s — a comma seperated array of output sizes
-t - a target group, which outputs a set of sizes suitable for icons
These options are not well tested, YMMV
-A - path to xcassets catalog to place the produced images into
-a YES|NO — include alpha channel, YES or NO
-b 1|4|8|12 — bits per channel
-c GRAY|INDEX|RGB|LAB|CMYK — color model
-C x,y,w,h — crop to rectange
-v - version info
-V - verbose
-z — crush, generate the smallest PNG possible
Output sizes can be expressed in a number of formats:
@ - Original Size
@2x - Retina Sizes
50 - Square Sizes (50x50)
100x50 - Rectangular Sizes
100@2x - Square Retina Sizes (200,200)
400% - Percentage Sizes
200w - Fixed width, proportinate height
200h - Fixed height, proportinate width
You have a logo for an application which is square, with large and small variants, that you want to render for both iOS and Android:
$ pdf2png -i app-logo-small.pdf -o app-logo -t ios-small
Is equivalent to:
$ pdf2png -i app-logo-small.pdf -o app-logo -s 29,29@2x,29@3x,40,40@2x,40@3x
