I am trying to save a packed image (generated via texture painting). To do this, I call unpack(), which should save the image, but I can't find it on my hard drive (Linux, blender 2.73). Does there exist a way for further customization (such as setting the image file format, file name, directory to save into, ..)?

The docs reference unpack

Given an image with the super descriptive name 'Untitled':

enter image description here

>>> bpy.ops.image.unpack(id='Untitled')
Warning: AutoPack is enabled, so image will be packed again on file save
Info: Saved packed file to: /home/zeffii/Downloads/textures/dances_packed.png

{'FINISHED'}

If you look in console you'll see where it saved to.

But it is possible for certain to use plain old .save() too. Opening a .blend where the image is packed I did

bpy.data.images['Untitled'].filepath = '/home/zeffii/Desktop/some_name.png'
bpy.data.images['Untitled'].save()

And it stored straight to desktop

Things I don't know

How to save as a different file type, and how to force a different save directory for the unpack command.

  • $\begingroup$ Worth noting that you can call unpack without resorting to bpy.ops - bpy.data.images["Untitled"].unpack() - See: blender.org/api/blender_python_api_2_74_release/… You can set the filepath, then call unpack $\endgroup$

  • $\begingroup$ @ideasman42 why might I get the error RuntimeError: Error: Image not packed when running image.unpack() , the image is listed in datablock outliner in packed_files.. $\endgroup$

  • $\begingroup$ I called unpack directly on an Image instance, didn't use ops. There was no Info issued. Where's the catch? $\endgroup$ Apr 29, 2015 at 16:12
  • $\begingroup$ @zeffii, not sure, maybe this should be a bug report. $\endgroup$
