I'm doing a project with product selection by thumbnails. Also, each product has a 64x64 thumbnail and 320x320 image. There are 12 thumbnails (4 columns x 3 rows) on screen at a time.
It takes about 5 sec to display all twelve jpeg images on screen each time. When user press up or down, the screen shift up/down one row (4 thumbnails). Since there is 8 thumbnails still on screen, the program need to convert 4 more thumbnails only. It takes about 2 seconds. Is it more practical to use palm bitmap file format, with which the program should be able to display without delay? Of course, the file size will be bigger but the speed will be greatly increased. Any advice and suggestion with experience. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
