[PATCH] PNG export: indexed option doesn't work

    XMLWordPrintableJSON

    Details

    • Type: Bug
    • Status: Resolved
    • Resolution: Fixed
    • Affects Version/s: 1.8
    • Fix Version/s: None
    • Component/s: SVG Viewer
    • Environment:
      Operating System: All
      Platform: All

      Description

      The indexed option of the PNG export in the SVG viewer has no effect.
      This is because KEY_INDEXED is set to 256 while it seems to be expected
      to be 8 if the number of palette entries should be 256 = 2^8.
      A value of 256 will be ignored in
      sources/org/apache/batik/ext/awt/image/codec/png/PNGTranscoderInternalCodecWriteAdapter.java

      I'll post a simple patch, but the indexed option is still quite unusable
      because it dithers a white background, even if only one other color is used.
