The issue is that I wanted to draw a dynamic 2D image and some static labels on the image (the static label doesn’t need to change in each swap buffer) I assume that it’s not efficient to draw the static labels each time when the background image is changing so what is the best approach to draw?
I tried these two ways:
1-I draw the label each time.
2-Use of eglCreatePbufferFromClientBuffer and bind it to VGImage then paint on VGImage and then show the VGImage.
The things that was weird to me was realizing that:
a) The first approach is faster than the second one!
b) When you use the eglCreatePbufferFromClientBuffer you cannot use of antialiasing that set in EGLConfig so your font was untidy!(At least I couldn’t use it with antialiasing)
I just know these two ways to draw, I look forward to any new idea for drawing efficiently and also I appreciate anybody that explain (a) and (b) to me.
