Here is a method to write a PETmate json file, maybe you can add it to the repo

[deadline-cxn]

Below you will find the function for reading in a PETmate (https://nurpax.github.io/petmate/) json file and write it out. It takes into account arbitrary width and height, and can be written to x,y on the screen. Hope this helps some people, please add it in to the repo if you can.

I attached an example json file that was created from PETmate, which you can also include in the repo if you'd like. art.zip

I just realized that the REVON and REVOFF can be optimized a little better to not write on every character, similar to how I did the lastcolor variable. So something like lastreverse variable condition should be added for the reverse status.

[deadline-cxn]

Here is an image example of it in action: You can also overlay smaller sized petscii files using the gotoXY() function like so:

[deadline-cxn]

Okay so here is the updated method that has the reverseStatus optimization added so it doesn't write the reverse code every character. Only when the reverse status changes will it write the reverse status out.

private void PETmateJSON(final String File) throws Exception { PETmateJSON(File, 0, 0); };

    for (int i = 64; i < 96; i++)   { codehash.put(i, i + 128); }
    for (int i = 96; i < 128; i++)  { codehash.put(i, i + 64); }
    for (int i = 128; i < 160; i++) { codehash.put(i, i - 64); }
    for (int i = 160; i < 192; i++) { codehash.put(i, i - 128); }

Just added it to the codebase. Thank you dude!
