Gary Lucas commented on IMAGING-361:
------------------------------------
Just found that this issue repeats previously reported issue Imaging-337.
> ImageInfo reports wrong color-type for non-RGB TIFF files
> ----------------------------------------------------------
>
> Key: IMAGING-361
> URL: https://issues.apache.org/jira/browse/IMAGING-361
> Project: Commons Imaging
> Issue Type: Bug
> Components: Format: TIFF
> Reporter: Gary Lucas
> Priority: Minor
>
> 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}
