Gaussian Blur on texture

[febingeorge]

what is width and height here?
If my image size 720X480 does it mean width is 720 and height is 480.
Or is it the size of the window

I got answer for the above question.
But now I have another question, in the earlier example of a fragment shader it uses 7x1 matrix.
What if I want to use 7x7 matrix?

Hi Vexator I have one question, in the earlier example of a fragment shader it uses 7x1 matrix.
What if I want to use 7x7 matrix? Do I have to use a nested loop with u_Scale = vec2(1.0/width, 1.0/height )
