API TextureBase SetTexCoord

Sets the coordinates for cropping or transforming the texture. TextureBase:SetTexCoord(left, right, top, bottom) TextureBase:SetTexCoord(ULx, ULy, LLx, LLy, URx, URy, LRx, LRy)

Coordinates of the four (transformed) image edges.

• : - Left (or minX) edge of the scaled/cropped image, as a fraction of the image's width from the left.
• : - Right (or maxX) edge of the scaled/cropped image, as a fraction of the image's width from the left.
• : - Top (or minY) edge of the scaled/cropped image, as a fraction of the image's height from the top.
• : - Bottom (or maxY) edge of the scaled/cropped image, as a fraction of the image's height from the top.

Coordinates of the four (transformed) image corners.

• : - Upper left corner X position, as a fraction of the image's width from the left.
• : - Upper left corner Y position, as a fraction of the image's height from the top.
• : - Lower left corner X position, as a fraction of the image's width from the left.
• : - Lower left corner Y position, as a fraction of the image's height from the top.
• : - Upper right corner X position, as a fraction of the image's width from the left.
• : - Upper right corner Y position, as a fraction of the image's height from the top.
• : - Lower right corner X position, as a fraction of the image's width from the left.
• : - Lower right corner Y position, as a fraction of the image's height from the top.

• The four-coordinate version of this function is well-suited to cropping textures. The eight-coordinate version can perform affine transformations, i.e. scaling, translating, shearing and rotating the source image.
• The coordinates used by this function are normalized and vertically reversed compared to traditional WoW frame rectangles: (0,0) is the top-left corner of the image; (1,1) is the bottom right corner.
• You may supply coordinates outside the [0, 1] range; the behavior varies depending on the texture displayed by the texture widget, as well as whether tiling is enabled.
• Interface\ICONS textures are loaded into composite textures by the client; you cannot tile them, and other icons may appear outside the [0,1] coordinate region.
• When tiling is enabled, the image is repeated outside the [0,1] texture coordinates.
• When tiling is disabled, the outermost pixels of the source image are repeated indefinitely outside the [0,1] texture coordinates.
• does not clear the transformation. Call to display the original image if necessary.
