Use the simpler form with the 4 numbers (you can think of them as percentage height/width anchored to the top-left)
Code:
0,0---------1,0
| |
| |
| |
0,1---------1,1
SetTexCoord(
x1,x2,
y1,y2)
first 2 numbers define width, last 2 height.
0,1 = 100% width of original texture.
0,1 = 100% height of original texture.
(
0,0.75,
0,0.75) = 75% width, 75% height anchored topleft.
(
0.25,1,
0.25,1) = 75% width, 75% height anchored bottomright.
You get the idea.
For an alternative zork's work using scrollframes for cropping is a trove of information as well.
