Android.Opengl.GLUtils.TexSubImage2D Method

Calls glTexSubImage2D() on the current OpenGL context.

Syntax

[Android.Runtime.Register("texSubImage2D", "(IIIILandroid/graphics/Bitmap;)V", "")]
public static Void TexSubImage2D (Int32 target, Int32 level, Int32 xoffset, Int32 yoffset, Bitmap bitmap)

Parameters

target
level
xoffset
yoffset
bitmap

Remarks

Calls glTexSubImage2D() on the current OpenGL context. If no context is current the behavior is the same as calling glTexSubImage2D() with no current context, that is, eglGetError() will return the appropriate error. Unlike glTexSubImage2D() bitmap cannot be null and will raise an exception in that case. All other parameters are identical to those used for glTexSubImage2D(). NOTE: this method doesn't change GL_UNPACK_ALIGNMENT, you must make sure to set it properly according to the supplied bitmap. Whether or not bitmap can have non power of two dimensions depends on the current OpenGL context. Always check glGetError() some time after calling this method, just like when using OpenGL directly.
