=== About ===

This is a simple command line tool that takes a list of PNG image files and creates a somewhat optimized texture atlas. It might rotate images if that will allow the texture atlas to be smaller.

=== Usage ===

   ./texture-atlas  [-i <string>] ...  [-q] [-y <pixels>] [-x <pixels>] [-o
                    <string>] [--] [--version] [-h] <PNG file path> ...

   -i <string>,  --info_writers <string>  (accepted multiple times)
     Atlas information writers: csv

   -q,  --quiet
     Suppress processing information output.

   -y <pixels>,  --out_height <pixels>
     Maximum output atlas image's height.

   -x <pixels>,  --out_width <pixels>
     Maximum output atlas image's width.

   -o <string>,  --out_name <string>
     Output atlas image's file name.

   --,  --ignore_rest
     Ignores the rest of the labeled arguments following this flag.

     Displays version information and exits.

   -h,  --help
     Displays usage information and exits.

   <PNG file path>  (accepted multiple times)
     (required)  List of the image filenames.

   Creates a texture atlas from a list of PNG files.

Packing three images that are 128x128, 64x64 and 256x256 to 256x256 pixel texture atlases.

$ ./texture-atlas -i csv -x 256 -y 256 image/asteroid.png image/asteroid_mineral.png image/sun.png

Packed 2 images to out_atlas_0.png with 12288 unused area Width (128) x Height (256)
image/asteroid.png => x: 0 y: 0 width: 128 height: 128
image/asteroid_mineral.png => x: 0 y: 128 width: 64 height: 64

Packed 1 images to out_atlas_1.png with 0 unused area Width (256) x Height (256)
image/sun.png => x: 0 y: 0 width: 256 height: 256

$ cat out_atlas.csv
atlas_name, atlas_packed_count, atlas_wasted_pixels, atlas_width, atlas_height, texture_name, texture_rotated_90, texture_width, texture_height, texture_x_offset, texture_y_offset
out_atlas_0.png, 2, 12288, 128, 256, image/asteroid.png, 0, 128, 128, 0, 0
out_atlas_0.png, 2, 12288, 128, 256, image/asteroid_mineral.png, 0, 64, 64, 0, 128
out_atlas_1.png, 1, 0, 256, 256, image/sun.png, 0, 256, 256, 0, 0
