glTexImage2D

Specifies the target texture. Must be GL_TEXTURE_2D , GL_PROXY_TEXTURE_2D , GL_TEXTURE_1D_ARRAY , GL_PROXY_TEXTURE_1D_ARRAY , GL_TEXTURE_RECTANGLE , GL_PROXY_TEXTURE_RECTANGLE , 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_PROXY_TEXTURE_CUBE_MAP .

Specifies the level-of-detail number. Level 0 is the base image level. Level n is the n th mipmap reduction image. If target is GL_TEXTURE_RECTANGLE or GL_PROXY_TEXTURE_RECTANGLE , level must be 0.

Specifies the number of color components in the texture. Must be one of base internal formats given in Table 1, one of the sized internal formats given in Table 2, or one of the compressed internal formats given in Table 3, below.

Specifies the width of the texture image. All implementations support texture images that are at least 1024 texels wide.

Specifies the height of the texture image, or the number of layers in a texture array, in the case of the GL_TEXTURE_1D_ARRAY and GL_PROXY_TEXTURE_1D_ARRAY targets. All implementations support 2D texture images that are at least 1024 texels high, and texture arrays that are at least 256 layers deep.

This value must be 0.

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_RED_INTEGER , GL_RG_INTEGER , GL_RGB_INTEGER , GL_BGR_INTEGER , GL_RGBA_INTEGER , GL_BGRA_INTEGER , GL_STENCIL_INDEX , GL_DEPTH_COMPONENT , GL_DEPTH_STENCIL .

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 .

Specifies a pointer to the image data in memory.
