I am using Inkscape and Gimp to create assets for a word game and am looking for an advice from more experienced users of these great tools.
In Inkscape I have created a stripe with 26 letters and their values:
The stripe is comfortable to edit - I have enabled grid snapping there and also I can always revisit the SVG file and change font sizes or letter values.
Then I have exported the SVG file as a whole page to PNG files in different resolutions:
Unfortunately, loading a 6240 x 240 pixels PNG file does not work with Android (because of OpenGL width limitation for textures - 2048 pixels on many devices).
So I have to split the SVG file or the resulting PNG files in square images of 240 x 240 pixels for each letter (Android could process them without problems).
My question is if anyone knows a good way to perform such a split in Inkscape (that would be best) or in Gimp?
In Export Bitmap dialog of Inkscape I see a batch-related checkbox... Could it be used for my purposes?
Answer
Yes, you can do it in Gimp, but in my opinion is simpler with ImageMagick (see also here).
You need to put a lot of guidelines where you need to cut:
And then simply apply the Guillotine transform:
After this, you have the original image split in a lot of imagettes:
And you have to save - pardon, export - each of them with a proper name.
Ok, maybe you can use a script for the guidelines and apply the slice plugin (which saves the pictures in a folder) to make it faster...
In Inkscape you can choose the area to export, and you can simply calculate the proper coordinates and save each image:

Trust me, I love Gimp and Inkscape, but a more proper tool for this kind of operation is Imagemagick ;-).
