- Can anyone please provide me with some hints, pointers, advice or
- code to help me handle updates to a PICT (read in from a resource) within
- a window. I would like to only have to refresh portions of the PICT, rather
- than refresh the entire window, based on the current Update Region.
-
- Basically, I read in a specific PICT resource and display it in a window.
- Then as the user makes updates, I would like to only update (via the
- update event or program controlled) certain potions. I could read in the
- PICT again and display it but this is very slow and inefficient, considering
- all the other objects currently shown.
- There MUST be a better way !!
-
- Is it possible to READ IN and display portions of a PICT resource ?
- or Read in and store it elsewhere and then move portions of it around ?
- or Update specific portions easily ?
-
- Any help, advice or suggestions would be most gratefully received.
- Thanx in advance, for the help....
