Gary Lucas updated IMAGING-361:
-------------------------------
Description:
When TiffImageParser.getImageInfo() creates an ImageInfo object, it has a
hard-wired value for ColorType of RGB. So images with color models such as
CMYK or YCbCr are reported as RGB. It should look at the Photometric
Interpretation tag and assign a value accordingly.
Note that this issue has nothing to do with the kind of BufferedImage that
other methods will produce. A code fix would only affect the values reported
in ImageInfo.
The problem code is currently at line 534 in TiffImageParser.java, but examples
of accessing other TIFF tags are located nearby in the code.
{code:java}
final ImageInfo.ColorType colorType = ImageInfo.ColorType.RGB
{code}
