  • Component changed from undetermined to avcodec
  • Keywords sunrast added
  • Priority changed from normal to wish
  • Reproduced by developer set
  • Status changed from new to open
  • Type changed from defect to enhancement
  • Version changed from unspecified to git-master

Do you think the file is meant to be completely transparent? (It is imo likely that it actually should not be transparent at all.)
Could you try to encode an image that is part transparent, part opaque?

Sorry, I don't know how to create transparent sun raster (if it's possible), so I suggest support it without it.

  • Blocked By set to 869

Mostly fixed, remaining issues depend on ticket #869.

  • Blocked By changed from 869 to #869

comment:5 Changed 6 years ago by richardpl

IMHO blocking this bug by another, unrelated bug is pointless. This bug should and can be fixed without waiting for #869 to be fixed.

ImageMagick? displays wrong colors for this sample, what application created this file?

Our decoder incorrectly decodes 32bit ras created with ImageMagick?.

Need more info about generated sample.

  • Resolution set to fixed
  • Status changed from reopened to closed

Attached sample decodes visually incorrect now, but decoder matches what Gimp, ImageMagick? and xview do and what the terse specification indicates.
