GEGL Background in GIMP
GIMP 2.8.4 Windows 7 64-bit
Using the native GIMP rotate function to rotate a rectangular image about its centre (for instance) the corners of the image which are exposed by the rotation are set to RGB 0x000000 with an alpha value of 0.so that these areas are transparent.
If the same operation is performed as a GEGL operation the corners have RGB values of 0x000000 but alpha values of 255 - i.e. they are solid black.
Is there a setting to cause GEGL to use alpha values of 0 for these pixels?
This also applies to GEGL operations such as shear.

Adding an alpha channel causes the areas exposed by the rotation to have a graduated transparency. Problem solved.
