list tilesets and images in the file, along with an id that can be passed to the other commands.

extract all the images in the file, saving them into the current directory as a separate .png file per image.

extract all the images in the file, combining them into one .png file per tileset (e.g. as a grid of 10x10 tiles.) Grid size is controlled via the --width option.

extract id from the tileset, saving it as dest.png (or into the current directory as id.png if dest.png is not supplied.)

replace id with the data from new.png. The image must be in the correct format (bit depth) or an error will be returned. The palette in the image file (if any) is not changed, so for best results the palette in new.png should match the one generated when extracting images. If new.png is not specified, id.png is used.

store new.png at the position id, shifting the original id and all following tiles closer to the end of the file. If new.png is not specified, id.png is used.

add an empty tileset at position id, shifting the original id and all following sub-tilesets closer to the end of the file. This can only be used with file formats that support sub-tilesets.

print image id to standard output using ANSI codes and spaces to display the image on a text console.

set all images in the tileset id to W pixels wide and H pixels high. This will cause all images to become distorted, so all images will need to be overwritten after this operation.

manually specify the file type. The type is normally autodetected, but it needs to be specified for a few formats which lack signatures to identify them by. See --list-types.

show a list of supported file formats, along with the value to pass to --type.

when using --extract with a tileset or --extract-all-tilesets, this option controls the width of the .png image, measured in tiles. A tileset with 32 images and a --width of 8 will result in a .png file of 8x4 tiles.

open the file as the given --type, even if it doesn't look like it's in that format.

print output suitable for parsing by a script.

display a list of the images inside the main Crystal Caves graphics file.

extract every image in every tileset as a separate .png file into the current directory.

extract all the tilesets into a handful of .png files in the current directory (all the images in each tileset are displayed as a grid in each .png file.)

print the third image ("2") from the second tileset ("0.1") as ANSI coloured text.

extract the third image ("2") from the second tileset ("0.1") and save it as test.png in the current directory.

overwrite the image extracted in the previous example with the contents of new.png.

list contents of the tileset, when the format can't be autodetected and must be specified manually with --type.
