GUI server draw-image JPEG load problem...
Posted: Mon Oct 12, 2015 9:08 pm
Hi!
I'm doing a simple picture viewer using the GUI server. However, I am having an odd problem where sometimes the image loads and sometimes it doesn't. If I advance to the next image then come back to one that didn't load, it will often load then.
I am using this to clear the previous image, then load and draw a new image into the canvas:
The images are generally about 4Kx2.5K, scaled to 625x521 (for the psize argument).
When the image load fails (?), the text draws following it fail also, so nothing is shown.
Any ideas as to what's going on -- and how I can fix it?
Thanks!

Code: Select all
(gs:delete-tag 'I)
(gs:draw-image 'I path 0 0 (psize 1) (psize 0))
(gs:draw-text 'I path 21 25 '(0 0 0))
(gs:draw-text 'I path 20 24 '(1 1 0)))
