Summary | 0001313: Image files with greater than 8 bits per channel are always compressed down to 8-bits-per-channel | ||||
Description | I think it just needs MagickImageProxy::image to be extended to use ShortPixel if required; the tricky part is knowing the bit depth without reading the image into memory; probably needs to be found by the examiner and passed down that way. Otherwise you need to create a Magick::Image just to get the bit depth (it seems) which gets fiddly quite fast. | ||||

is that in 2.13.x only? Does it mean DCP-o-matic does no handle >8bit images in their native bit depth?
|
|
@carl or maybe just use FFmpeg. |
|
It has never done > 8-bit image files in their native depth. Video files should be OK. |
|
@carl: the existing FFmpeg code can load (e.g.) PNGs with no modification; the only question is how to sustain the existing image file / sequence behaviour. With FFmpegDecoder you get a 1-frame-length video. |
|
But that would have been true for images sequences as well, as the notorious 12Bit XYZ, or DPX sequences? Or, really only 'stills'?
|
|
JPEG2000 image files are special-cased, but DPX, yes. |
|
Should be fixed by using FFmpeg for images in 2.13.61 and above. |
