If you haven't run across it, one day you will. The game with fonts or graphics NOTHING can view or edit. Maybe it's 7x8, 14x18, 16x11 or some other insanely inefficient size. Maybe it just happens to have an incredibly jacked up byte ordering. Or maybe you just want to edit graphics the way they look without playing Humpty-Dumpty in a limited, tile editor workspace.
You tried Nana, but screamed in pain when you realized, not only will Nana not edit your fonts or graphics, but it won't show any tile arrangements in 1bpp that are not a multiple of 8. Maybe you tried Tile Molester to discover it's either a bitch to use or unable to handle what you need.
Or maybe you're just like me, and you think tile editors suck and would rather be using Photoshop or GIMP. If any of the above apply, you might have a use for FEIDIAN.
FEIDIAN is an all-purpose, multi-platform, bitplane graphic dumper. It operates at absolutely any tile size supports any number of columns and rows, and has a tile definition format so when you run into those odd games that are too cool to follow NORMAL bit ordering, you can set up your own. Its built-in dumping system handles monochrome graphics, but with tile definitions, it can support up to 16 colors with a user-defined palette.
It can also be used to create a font matching a dual tile set's specs, pad tiles for OCR use, perform Binary Character recognition on two fonts to fill in a table, scale graphics, and to convert an ASCII ordered, monochrome bitmap to a textual font representation (such as FD or BDF) which can, depending on your OS, either be used immediately or easily converted to another format using something like Simon Tatham's mkwinfont.
Thanks to FEIDIAN being written in PHP, it can be used on Windows, Linux, FreeBSD/variant, AmigaOS, Mac OS X, Novell NetWare, OS/2, RISC OS, SGI's IRIX, AS/400 and probably a few others (QNX...?). It may be able to offer a solution to translation work on systems other than Windows.
