Subject [jira] [Updated] (IMAGING-141) BufferedImage from TIFF is always 24 or 32 bpp
Date Mon, 27 Oct 2014 19:55:33 GMT

     [ https://issues.apache.org/jira/browse/IMAGING-141?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Josh Highley updated IMAGING-141:
---------------------------------
    Description: When getting a BufferedImage from a TIFF, TiffImageParser.getBufferedImage
gets the TIFF's BPP from the TIFF tags, but at the end ImageBuilder.getBufferedImage() will
always set the BufferedImage ColorModel BPP to 32 for images with alpha and 24 bpp otherwise.
 Many TIFFs are 1 bpp (G3 and G4) so the BufferedImage should also be 1 bpp.  (was: When getting
a BufferedImage from a TIFF, TiffImageParser.getBufferedImage gets the TIFF's BPP from the
TIFF tags, but at the end ImageBuilder.getBufferedImage() will always set the BufferedImage
ColorModel BPP to 32 for images with alpha and 24 bpp otherwise.  Many TIFFs are 1 bpp (G4
and G6) so the BufferedImage should also be 1 bpp.)
