The arguments are as follows: .Bl -tag -width Ds .It Fl D Debug features are enabled. .It Fl f Fix the input PNG file to be a correctly indexed image. .It Fl F Same as .Fl f , but additionally, the input PNG file is fixed to have its parameters match the command line's parameters. .It Fl d Ar depth The bitdepth of the output image (either 1 or 2). By default, the bitdepth is 2 (two bits per pixel). .It Fl h Lay out tiles horizontally rather than vertically. .It Fl o Ar outfile The name of the output file. .It Fl p Ar palfile Raw bytes (8 bytes for two bits per pixel, 4 bytes for one bit per pixel) containing the RGB15 values in the little-endian byte order and then ordered from lightest to darkest. .It Fl P Same as .Fl p , but the pallete file output name is made by taking the input filename, removing the file extension, and appending .Pa .pal . .It Fl t Ar mapfile If any tiles are the same, don't place the repeat tiles in the output file, and make a tilemap file. .It Fl T Same as .Fl t , but the tilemap file output name is made by taking the input filename, removing the file extension, and appending .Pa .tilemap . .It Fl u Truncate repeated tiles. Useful with tilemaps. .It Fl v Verbose. Print errors when the command line parameters and the parameters in the PNG file don't match. .It Fl x Ar tiles Trim the end of the output file by this many tiles. .El .Sh EXAMPLES The following will take a PNG file with a bitdepth of 1, 2, or 8, and output planar 2bpp data: .Pp .D1 $ rgbgfx -o out.2bpp in.png .Pp The following creates a planar 2bpp file with only unique tiles, and its tilemap .Pa out.tilemap : .Pp .D1 $ rgbgfx -T -u -o out.2bpp in.png .Pp The following will do nothing: .Pp .D1 $ rgbgfx in.png .Sh SEE ALSO .Xr rgbds 7 , .Xr rgbasm 1 , .Xr rgblink 1 , .Xr rgbfix 1 , .Xr gbz80 7 .Sh HISTORY .Nm was created by .An stag019 to be included in RGBDS.
