Note: QuickDraw picture data typically comes in two forms: a PICT resource
|
|
that begins the picture header data at the beginning of the resource and PICT
|
|
files that begin with 512 bytes of arbitrary data, followed by
|
|
the picture header data. For this reason, the routines that create a QDPictRef
|
|
attempt to find the picture header data beginning at either the first byte
|
|
of the data provided or at byte 513 of the data provided.
|
|
|
|
Additionally the Picture Bounds must not be an empty rect.
