Texture.saveToTiffBytes

Store the given texture in memory as a TIFF file.

Use gdk.texture.Texture.newFromBytes to read it back.

This function is intended to store a representation of the texture's data that is as accurate as possible. This is particularly relevant when working with high dynamic range images and floating-point texture data.

If that is not your concern and you are interested in a smaller size and a more portable format, you might want to use gdk.texture.Texture.saveToPngBytes.
