This function sets the UV size of a DGS image (Only available when there is a texture loaded in DGS image).

Syntax

bool dgsImageSetUVSize ( element dgsImage, float UPos, float VPos, bool relative )

Required Arguments

  • dgsImage: The dgs image of which you want to set the UV size.
  • UPos: A float of the U size of image.
  • VPos: A float of the V size of image.
  • relative: This determines whether UV size is relative. If this is true, then UV size floats must be between 0 and 1, representing UV sizes relative to the pixels of the texture loaded.

Returns

Returns true if succeed, false otherwise.

Example

DGS = exports.dgs

local texture = dxCreateTexture("test.png") -- Example File
local image = DGS:dgsCreateImage(400,400,400,400,texture,false)
local UPos,VPos = DGS:dgsImageGetUVSize(image,false)
DGS:dgsImageSetUVSize(image,UPos+10,VPos+10,false)
