Hi,
1. Take a 24bit white or grey image (e.g. 960x540 )
2 do a resizing via Ctrl+R to anything bigger than the original size ( e.g. 1920x1080)
3. choose the Lanczos filter
4. execute resize operation
5. take a look at the histogram --> new white values 253 or 254 are introduced
any other resizing filter doesn't do that. It doesn't probably effect the image quality
in daily resizing tasks, but in my case it introduces some annoying artifacts.
Hope this can be fixed sooner or later.
Tested in Irfanview versions:
4.25
4.27
System setup:
win 7 x64 english
Quadcore intel xeon @ 2.67 GHz
12GB ram
