Tilman Hausherr reopened PDFBOX-3003:
-------------------------------------
My changes break preflight. There's a bug in the use of ColorSpaces.valueOf().
Colorspaces is an enum type:
{code}
public enum ColorSpaces
{
Lab("Lab"), CalRGB("CalRGB"), CalGray("CalGray"), DeviceN("DeviceN"),
Indexed("Indexed"), Indexed_SHORT("I"), Pattern(
"Pattern"), ICCBased("ICCBased"), DeviceRGB("DeviceRGB"),
DeviceRGB_SHORT("RGB"), DeviceGray("DeviceGray"), DeviceGray_SHORT(
"G"), DeviceCMYK("DeviceCMYK"), DeviceCMYK_SHORT("CMYK"),
Separation("Separation");
{code}
However the string parameter of valueOf "must match exactly an identifier used
to declare an enum constant in this type". I.e. "CMYK" cannot work (but
"DeviceCMYK_SHORT" would). This has worked until now because further code
worked as if this was a resource color name, which worked because the short
names were accepted by PDColorSpace.create(). Solution: rename the enum
elements.
