Convert a modern image file (jpg, png, etc) into a TRS80 BASIC program to reproduce the image on a TRS80 (low-res, black and white).

Allows for source image pan, zoom, and output image contrast adjustment.

Written as an entry into Dusty's www.trs-80.org.uk 2018 Competition: HI-RES-LO

Target is a TRS80 Model III, LDOS 5.3.1, and Misosys LBASIC.

• v1.5
• Added (I)nvert colors option
• Added .tim (TRS Image file) output file for use with TRS-80 Screen Designer (TSD)
• See www.plaidvest.com
• v1.4
• Cross platform version
• GUI = Tk/Tcl
• Increase performance when adjusting contrast
• v1.3
• Separate PC and Mac versions

• GUI = wxPython

Requirements:

• Python 3 (www.python.org)
• Pillow 5.2.0 (pip install Pillow)

Run from the terminal:

1. cd /folder/to/trsimage
2. ./trs_image.py

Run from the command prompt:

1. cd c:\folder\to\trsimage
2. python trs_image.py

Using the TRS Image BASIC output file(s):

• Copy BASIC program to a virtual .dsk image (I use TRS Tools)
  -or-
• Copy to actual diskette using your favorite method

1. Boot TRS80 Model III with LDOS 5
2. Switch to Misosys LBasic by typing BASIC
3. Load sample program: LOAD "xxx.BAS"
4. Run sample program: RUN
5. (Optional) Re-run with RUN or save the smaller program back to disk SAVE "xxx.BAS"
6. Return to LDOS with CMD"S"
