Setup OpenGL to use our image.

Delete completed edges. Update 'xIntersect' field for others

@TODO: Put in ilPKImageEncode_WritePixels_DevIL?

@TODO: Finish this, as it is incomplete.

calc_x_contrib() Calculates the filter weights for a single target column. contribX->p must be freed afterwards. Returns -1 if error, 0 otherwis

Returns the sum of squared differences between component color values, normed. * */

Returns the sum value of quantile of absolute differences among subpixels. * \param reference Left hand side image (LHS == RHS ?) * \param sample R

Create a new Params structure in the space and return a pointer to it */

What was created, must be destroyed! */

This subroutine encodes one scanline and writes it to a file. It returns number of bytes written into outBuff, 0 if failed.

Pretty damn unoptimized

Internal function used to check if the HEADER is a valid EXR header.

Internal function used to check if the HEADER is a valid .hdr header.

Internal function used to check if the HEADER is a valid .Jpg header.

Internal function used to check if the HEADER is a valid Lif header.

Internal function used to check if the HEADER is a valid .pnm header.

Same as iConvFloat16ToFloat32, but we have to set the blue channel to 1.0f. The destination format is RGB, and the source is R16G16 (little endian).

Last time I tried, MSVC++'s fgets() was really really screwy

Just created for internal use.

Internal function to figure out where we are in an image chain. @TODO: This may get much more complex with mipmaps under faces, etc.

changed name to iGetDateTime on 20031221 to fix bug 830196

Internal function used to get the .jpg header from the current file.

Modified version of jas_stream_fopen and jas_stream_memopen from jas_stream.c of JasPer so that we can use our own file routines.

Much easier to read - just assemble from planes, no decompression

Initializes the image stack's first entry (default image) -- ONLY CALL ONCE!

This is only called by ilDetermineSize. Associates iputc, etc. with "fake" writing functions in il_size.c.

Only to be called by ilDetermineSize. Returns the buffer size needed to save the current image as a Targa file.

Internal function to uncompress the .dcx (all .dcx files are rle compressed)
