Contextual visualization of images
Posted: Mon Nov 14, 2022 04:48 PM

Hi,

I'm flipping through xBbrowse. In the bChanged code block, bitmap files are loaded into XImage. However, if I do continuous scrolling (arrow, scrollbar slider, mouse wheel), there is a strong slowdown. Is it possible to optimize the contextual visualization of images ?

You can use a timer for this delay.

It will give you the change to browse without refreshing to ximage during the time set.
