John Hewson commented on PDFBOX-2240:
-------------------------------------
The "RGB" in "getRGBImage" refers to the color space rather than the exact
image format., this behaviour is in the JavaDoc:
{quote}
Returns the content of the given image as an AWT buffered image with an RGB
color space.
If a color key mask is provided then an ARGB image is returned instead.
{quote}
The image is either RGB or ARGB. Color key masks are very rare and images use a
lot of memory and CPU time, especially alpha channels.
