fix dereference before checking for NULL in the ImagingTransformAffine function 
The `imIn` pointer is checked for `NULL`, but it seems to be dereferenced before this check. You must first make sure that the pointer is not `NULL` before using it.

4b422db243 Add keep_rgb option to prevent RGB -> YCbCr conversion during JPEG write 
libjpeg automatically converts RGB to YCbCr by default.  Add a keep_rgb
option to disable libjpeg's automatic conversion of RGB images during
write.
