The short answer
Why use Triangle Crop?
A triangle gives a photo a strong upward direction. It works for posters and logo marks, and for mountain, tree, and roof shots that already have that shape.
The triangle points up: its tip is at the top center of the frame and its base runs along the bottom edge. It is drawn inside a square, so the PNG is square (1200 × 1200 by default) and both top corners are transparent.
Most of the visible area sits in the lower half, so frame the photo with the subject low and leave sky or empty space at the top, where it gets trimmed away. Mountains, trees, and roof lines already have the right shape.
There is no setting for a triangle pointing down or sideways. Rotate or Flip the finished PNG to get one; the transparent areas come along unchanged.
