function glCopyTexImage1D(int $target, int $level, int $internalformat, int $x, int $y, int $width, int $border) : void

arguments

1. int $target Specifies the target texture. Must be GL_TEXTURE_1D.
2. int $level Specifies the level-of-detail number. Level 0 is the base image level. Level n is the nth mipmap reduction image.
3. int $internalformat Specifies the internal format of the texture. Must be one of the following symbolic constants: GL_COMPRESSED_RED, GL_COMPRESSED_RG, GL_COMPRESSED_RGB, GL_COMPRESSED_RGBA. GL_COMPRESSED_SRGB, GL_COMPRESSED_SRGB_ALPHA. GL_DEPTH_COMPONENT, GL_DEPTH_COMPONENT16, GL_DEPTH_COMPONENT24, GL_DEPTH_COMPONENT32, GL_STENCIL_INDEX8, GL_RED, GL_RG, GL_RGB, GL_R3_G3_B2, 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, GL_RGBA16, GL_SRGB, GL_SRGB8, GL_SRGB_ALPHA, or GL_SRGB8_ALPHA8.
4. int $x Specify the window coordinates of the left corner of the row of pixels to be copied.
5. int $y
6. int $width Specifies the width of the texture image. The height of the texture image is 1.
7. int $border Must be 0.
