Image Quality.
Today I'm working on adding some new interface for my game and I have a question about 2D Image quality. Why are they blurred when located in the center of the screen and not in a corner? I did so the button moving along with the mouse and try move it around to see result, and it will always gets blurred if it is near the middle does not matter what coordinate. Image is always sharp in the edges of screen, why is it like that? it is very annoying.
Any ideas?
Sample Image:

RE: Image Quality.
Nice screen.
What are you using to draw the buttons? Button/GuiImage?

RE: Image Quality.
The issue is about aligning floating point coordinates to integer pixel coordinates.
I'll try to add automatic pixel aligning for gui objects very soon, so please wait for that.

Sure, Check your PM.
Ps, I current use this settings.
D.sync(true);
D.full(false);
D.mode(1360, 768);
D.shdSoft(1);
D.texFilter();
D.ambPower(0.3);
D.viewRange(200);

RE: Image Quality.
Hi,
I've just tested this, and it works ok. (DX9/DX10)
Are you sure you're using latest EsenthelEngine.lib? Could you try using Project\Rebuild?
Are you setting button size after setting resolution?
Are you using any custom methods for drawing the button (like virtual draw override?)
do you use custom viewports?

RE: Image Quality.
After changing the resolution or screen scale you need to re-adjust the button size if you wish to have 1:1 per-pixel size.

RE: Image Quality.
you can use:
draw()
{
image=... ; // set custom image
__super::draw(gpc);
}
default draw uses D.screenAlignToPixel(rect) on temporary rect (rect+gpc.offset) to align it per pixel
