[news.eclipse.technology.nebula] Re: load image to Gallery very slow

[Nicolas Richeton <Nicolas.richeton@xxxxxxxxx>]

Hi Gaston,

Loading and resizing images with SWT is not that fast and with this 
code, your application is frozen while it processes all images.

You should do the loading and resizing in a separate thread and use 
setImage after each image processed. Most applications work this way.

Additionnaly, you can post the code you use for resize, there may be 
possible speed improvements.
