Save TGA with Compression / RLE

[SmittyWerbenJJ]

In the Documentation we have no information about how to apply compression for TGA files. It just states that it is possible,but not how to do it.

TGA
Pillow reads and writes TGA images containing L, LA, P, RGB, and RGBA data. Pillow can read and write both uncompressed and run-length encoded TGAs.

Now I find for other file formats we have the option to set compression="someValue" while calling Image.save(), to define file compression.

The only hint on how to use this, I found from this test case which calls for rle=rle and it actually works

Pillow/Tests/test_file_tga.py

Line 26 in cb6c941

original_im.save(out, rle=rle)

Is this the only way to do TGA compression? Is this not written in the documentation (I could not find it)?

You can use the compression argument.

Pillow/Tests/test_file_tga.py

Line 217 in ad7be55

im.save(out, compression="tga_rle")

I've created PR #6546 to add this to the documentation.
