export a tilemap from an image using an existing tileset (feature request)

[sverx]

Since I don't think this is currently possible I marked this as a 'feature request'.
I would love if BMP2Tile could accept an image and an uncompressed binary tileset and generate the tilemap for the image using the provided tileset. Using this, one would be able to generate more images from the same shared tileset.

I think #2 would cover the same idea - namely, to draw a bunch of art on an image and have the tileset be the common tileset (perhaps defined carefully in an upper area to control the ordering) but then also be able to extract tilemaps built from this shared tile set.

well, very similar but slightly different in usage, as the tileset would be generated the 'usual' way from a single source image (for instance the meta-tileset used in Tiled or similar map editors) and then additional images would re-use that generated tileset in a subsequent BMP2Tile processing.

As an alternative, would it be possible to have an option to generate the tileset from a second BMP/PNG instead?
So that I would use the tileset image to generate the tileset and the source image to generate the tilemap?

It would work this way:

• load the 'tileset' input image
• generate the tileset
• load the 'source' input image
• generate the tilemap from this image using the tileset created beforehand

(of course the point here is to save the tilemap)

(command line option could be)
-sourcetiles <filename>

[maxim-zhao]

It makes sense and is similar to what currently happens in the Sonic 1 editor...

[sverx]

the icing on the cake would be to support both an image (used then to generate the tileset) or an uncompressed binary file tileset as the -sourcetiles parameter

[maxim-zhao]

Well, that's already supported - you can load VRAM dumps (with extension .bin) but it doesn't make sense to create a palette or tilemap from them.

[sverx]

I don't think I get what you mean here... can you load a source image and a VRAM dump? 🤔

[maxim-zhao]

No - you can load a VRAM dump and save the tiles, but of course there's no dual-loading mode available yet. So in one respect, you can already load VRAM dumps.
