vips_colourspace (
  VipsImage* in,
  VipsImage** out,

Description [src]

This operation looks at the interpretation field of in (or uses source_space, if set) and runs a set of colourspace conversion functions to move it to space.

For example, given an image tagged as VipsInterpretation, running vips_colourspace() with space set to VipsInterpretation will convert with vips_Yxy2XYZ() and vips_XYZ2Lab().

::: tip “Optional arguments” * source_space: VipsInterpretation, input colour space
