BUG DxDrawImage black alpha background

[skadlskdlaskld]

Hello, I want to tell you about a small problem. Please fix it. When I use DxDrawImage, where the transparent part is, the color that was transparent becomes opaque and this is visible when I rotate the image. Roughly speaking, a transparent color has its own color and it becomes opaque when rotated. I am attaching a screenshot to show what color the transparent field is. When I lighten the color through effects in Photoshop, transparent pixels become white, but if I change the size it becomes black, and this defect is visible in MTA
