Changeset 7120 for trunk/psLib/src/imageops/psImagePixelExtract.c

Timestamp:

May 15, 2006, 3:20:09 PM (20 years ago)

Author:

Paul Price

Message:

Rows and columns were confused (psImageRow extracted a column, and
psImageCol extracted a row). Changed type macros from functions into
case statements, to avoid extraneous function call. Optimised
psImageRow, using memcpy.
