T glTexImage2D Chapter 18 glTexImage2D glTexImage2D: specify a two-dimensional texture image. C Specification void glTexImage2D( GLenum target, GLint level, GLint internalformat, GLsizei width, GLsizeiheight, GLint border, GLenum format, GLenum type, const GLvoid *pixels) Parameters target level internalformat width height border Specifies the target texture. Must be GL_TEXTURE_2D or GL_PROXY_TEXTURE_2D. Specifies the level-of-detail number. Level 0 is the base image level. Level n is the nth mipmap reduction image. Specifies the number of color components in the texture. Must be 1, 2, 3, or 4, or one of the following symbolic constants: GL_ALPHA, GL_ALPHA4, GL_ALPHA8, GL_ALPHA12, GL_ALPHA16, GL_LUMINANCE, GL_LUMINANCE4, GL_LUMINANCE8, GL_LUMINANCE12, GL_LUMINANCE16, GL_LUMINANCE_ALPHA, GL_LUMINANCE4_ALPHA4, GL_LUMINANCE6_ALPHA2, GL_LUMINANCE8_ALPHA8, GL_LUMINANCE12_ALPHA4, GL_LUMINANCE12_ALPHA12, GL_LUMINANCE16_ALPHA16, GL_INTENSITY, GL_INTENSITY4, GL_INTENSITY8, GL_INTENSITY12, GL_INTENSITY16, GL_R3_G3_B2, GL_RGB, GL_RGB4, GL_RGB5, GL_RGB8, GL_RGB10, GL_RGB12, GL_RGB16, GL_RGBA, GL_RGBA2, GL_RGBA4, GL_RGB5_A1, GL_RGBA8, GL_RGB10_A2, GL_RGBA12, or GL_RGBA16. Additionally, if the extension GL_EXT_shadow is supported, may be one of the symbolic constants GL_DEPTH_COMPONENT, GL_DEPTH_COMPONENT16_EXT, GL_DEPTH_COMPONENT24_EXT, or GL_DEPTH_COMPONENT32_EXT. Specifies the width of the texture image. Must be 2n + 2 × border for some integer n. All implementations support texture images that are at least 64 texels wide. Specifies the height of the texture image. Must be 2m + 2 × border for some integer m. All implementations support texture images that are at least 64 texels high. Specifies the width of the border. Must be either 0 or 1. 439
