Namespace: Ab4d.SharpEngine.Common
Assembly: Ab4d.SharpEngine (in Ab4d.SharpEngine.dll) Version: 2.0.8956+4c7684e186ca1be74e7a284fbe739d9a1b843d3c
Syntax
C#
Copy

	int stride,
	int alphaOffset = 3,
	int pixelSize = 4
)

Parameters

imageDataPtr  IntPtr
IntPtr to byte array with image data
width  Int32
texture width in pixels
height  Int32
