Signature

glCopyTexSubImage2D( GLenum ( target ) , GLint ( level ) , GLint ( xoffset ) , GLint ( yoffset ) , GLint ( x ) , GLint ( y ) , GLsizei ( width ) , GLsizei ( height ) )-> void
glCopyTexSubImage2D( target , level , xoffset , yoffset , x , y , width , height )

Parameters

VariablesDescription
target
Specifies the target texture. Must be GL_TEXTURE_2D , GL_TEXTURE_CUBE_MAP_POSITIVE_X , GL_TEXTURE_CUBE_MAP_NEGATIVE_X , GL_TEXTURE_CUBE_MAP_POSITIVE_Y , GL_TEXTURE_CUBE_MAP_NEGATIVE_Y , GL_TEXTURE_CUBE_MAP_POSITIVE_Z , GL_TEXTURE_CUBE_MAP_NEGATIVE_Z , or GL_TEXTURE_1D_ARRAY .
level
Specifies the level-of-detail number. Level 0 is the base image level. Level n is the n th mipmap reduction image.
xoffset
Specifies a texel offset in the x direction within the texture array.
yoffset
Specifies a texel offset in the y direction within the texture array.
x, y
Specify the window coordinates of the lower left corner of the rectangular region of pixels to be copied.
width
Specifies the width of the texture subimage.
height
Specifies the height of the texture subimage.
