resampling

SketchTape

I hate to make a thread about this, but if resampling is the reason for the red dots seen via webcam why would they be on the radar it is basically the only static part of each frame. Anyway whatever just need someone to clarify.

When there are many pixels in a single image, and when you move your mouse(hence your screen moving) the pixels are changed to modify the overall size and resolution of an image. Because resampling changes the structure of an image, it can also break animations.

for example:

http://www.google.com/imgres?um=1&safe=off&sa=N&hl=en&biw=1280&bih=961&tbm=isch&tbnid=KH8JQ4RH_-BbmM:&imgrefurl=http://www.imagemagick.org/discourse-server/viewtopic.php%3Ff%3D22%26t%3D21415&docid=AE_pVaH8KmhjjM&imgurl=http://web.cs.laurentian.ca/nrobidoux/misc/sigmoidal/lanczosLinear.png&w=800&h=526&ei=3K2NUavQCJKl4APH7oCoAg&zoom=1&ved=1t:3588,r:57,s:0,i:264&iact=rc&dur=193&page=3&tbnh=182&tbnw=277&start=57&ndsp=25&tx=189&ty=151

in layman's terms:
Basically, the image is changed completely. It can get ghosted due to movement. Ghosting literally means like a copy of the image before, its like two collapsed frames moved a little bit away from each other to make it look like there's two.(Basically, imagine yourself seeing from far away with bad eyesight)

The reason it's popping out on the minimap is because, in most video games, the minimap is the most pixel-collapsed image that is constantly changing and ghosting constantly occurs, with all those images being ghosted and resampled because there is so many, the pixels are changed completely in terms of size and color(depending on the color of the minimap of course)

I don't see why is matters how minimaps are in most videos; shouldn't only crossfire matter in this case?

Most of the minimaps in CF are roughly 256x256.
