NAME

     ncgr2tga — Nintendo NCGR image to TGA converter

SYNOPSIS

     ncgr2tga [options] width height ncgr [ngr ...] nclr tga

DESCRIPTION

     ncgr2tga converts Nintendo's tile-based NCGR images into common TGA images.

     2D graphics on the Nintendo DS is fundamentally tile-based.  Specifically, the graphics data in NCGR is
     ordered in tiles of 8×8 pixels.  Moreover, an NCGR file can itself be a tile of a larger image.  This tool
     can automatically combine and unwrap these tiles, and, together with an NCLR file for the palette, converts
     a grid of NCGR into a plain old linear TGA image.

OPTIONS

     -h
     --help
           Show a help text and exit.
     --version
           Show version information and exit.
     width
         The width of the NCGR grid, in NCGR files.
     height
         The height of the NCGR grid, in NCGR files.
     ncgr
         The name of an NCGR file to use.  The NCGR contains the pixel graphics part of the image.

         width × height NCGR files have to be given; they are drawn into the final TGA in row-major order.  An
         empty filename, commonly specified with "", means that this grid cell will be empty, filled with
         palette entry 0.
     nclr
         The name of the NCLR file to use.  The NCLR file contains the palette part of the image.
     tga
         The resulting TGA file will be written there.

LIMITATIONS

     •   Only NCGR files with version 1.1 are supported
     •   Only NCLR files with version 1.0 are supported
     •   Only palettes with bit-depths of 4 or 8 are supported
     •   Non-tiled or partitioned NCGR files are not supported
     •   Some NCGR files don't contain valid width/height values, and seem to need an NCER file for this
         information.  These files are currently not supported

EXAMPLES

     Convert a 2×3 grid of NCGR files:

           $ ncgr2tga 2 3 a0.ncgr a1.ncgr a2.ncgr a3.ncgr a4.ncgr a5.ncgr \
             a.nclr a.tga

     Convert a 2×2 grid of NCGR files, leaving the lower left quadrant blank:

           $ ncgr2tga 2 2 b0.ncgr, b1.ncgr "" b2.ncgr b.nclr b.tga
