Would be nice if you could add alpha option to select premultiplied/straight for alpha capable format such as PNG/TIF/TGA. it would make round trip editing with other apps easier. Straight alpha means RGB channels including transparent part will remain untouched without filled with a color. if I open a TGA that's with straight alpha and export as TGA, it will be premultiplied which is pain.

Hello again, can someone please tell me if it is possible to premultiply incoming EXRs with alpha channel? Currently, when I open an EXR the alpha channel is on a separate pixel layer as a black and white mask instead of premultiplying RGB by it or loading the alpha channel into the actual alpha channel under channels...channel channel....channel channel. This requires me to use the Flood Select Tool to get the mask from the alpha layer...^^ not very clean. The EXRs come from Redshift and act normal in PS and Nuke.
