Parameters

Variables	Description
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.
width	Specifies the width of the texture subimage.
height	Specifies the height of the texture subimage.
format	Specifies the format of the pixel data. The following symbolic values are accepted: GL_RED , GL_RG , GL_RGB , GL_BGR , GL_RGBA , GL_BGRA , GL_DEPTH_COMPONENT , and GL_STENCIL_INDEX .
type	Specifies the data type of the pixel data. The following symbolic values are accepted: GL_UNSIGNED_BYTE , GL_BYTE , GL_UNSIGNED_SHORT , GL_SHORT , GL_UNSIGNED_INT , GL_INT , GL_FLOAT , GL_UNSIGNED_BYTE_3_3_2 , GL_UNSIGNED_BYTE_2_3_3_REV , GL_UNSIGNED_SHORT_5_6_5 , GL_UNSIGNED_SHORT_5_6_5_REV , GL_UNSIGNED_SHORT_4_4_4_4 , GL_UNSIGNED_SHORT_4_4_4_4_REV , GL_UNSIGNED_SHORT_5_5_5_1 , GL_UNSIGNED_SHORT_1_5_5_5_REV , GL_UNSIGNED_INT_8_8_8_8 , GL_UNSIGNED_INT_8_8_8_8_REV , GL_UNSIGNED_INT_10_10_10_2 , and GL_UNSIGNED_INT_2_10_10_10_REV .
data	Specifies a pointer to the image data in memory.
