ReadMisc/TestImagePCX fails

[devernay]

it gives a black image on linux and macOS
It was working OK in Natron 2.2.9

[rodlie]

Will take a look after work today.

convert from the SDK is able to convert PCX, but reading a PCX in Natron results in a black image. If I build ReadMisc against system ImageMagick (6.9.10-23) then Natron reads the PCX file just fine.

I guess this is what breaks PCX

[rodlie]

Changes in XCF does not break PCX.

[devernay]

ah yes I mixed the letters ;-)

Makes me think we could ship the IM utilities with Natron, just as we ship the oiio ones.

[rodlie]

Can't hurt.

I will try to find why PCX fails, but to be honest, does anyone care? it's an old relic from the DOS era, superseded by BMP.

Makes me think we could ship the IM utilities with Natron, just as we ship the oiio ones.

And it would be even easier with IM7, which I think has only one utility (magick).

I'm OK if you disable PCX support in Natron (either at compile time or at run time)

[rodlie]

which I think has only one utility (magick).

Correct, you only need to prefix commands with magick.

magick convert, magick identify etc.

Can do.

[devernay]

perhaps this has to do with the fact that your system IM has different HDRI/depth settings than Natron's?

[rodlie]

I tried Q16 with and without HDRI, same result. Can try with Q8.
