Hello,
I am fairly new to OpenGL and beginner. I am using OpenTk in my application to capture screen.
I am using GLPixelread The problem is I want to have a high resolution of the image that is being selected by mouse. I tried setting frame buffer and then setting Gl. Viewport but the image saved in the bitmap is always the full screen. Not the part that has been selected I tried passing X, Y and width and height of the rectangle selection but It didn' work.https://solitaire.onl/ 9apps.ooo/ https://bluestacks.vip/
