1

Returns the size (in bytes) of the image array if it is compressed. See glGetTextureLevelParameter, GL_TEXTURE_COMPRESSED_IMAGE_SIZE.

2

Returns the internal data format of the image array. See glGetTextureLevelParameter, GL_TEXTURE_INTERNAL_FORMAT.

3

Stores the image of this texture with the specified level of detail in uncompressed form into the dest buffer. See glGetTextureImage.

[Note] Note

This function, unlike GetCompressedImage, does NOT automatically resize the destination buffer so that it can accomodate the texture data. The caller is responsible for keeping track or querying the type of the texture, its dimensions and current pixel transfer settings and resize the dest buffer accordingly.

4

Stores the image of this texture with the specified level of detail in compressed form into the dest buffer. See glGetCompressedTextureImage. This function automatically resizes the buffer so that it can accomodate the texture data.

5

Specifies a three dimensional texture image. See glTextureImage3D.
