Irgendwer Posted October 20, 2017 Share Posted October 20, 2017 (edited) Hi, has anyone got BASIC code to load or can supply the specs of the image format for the Atari Artist Tablet software? Cheers. I guess you like to load the native compressed "Micro Illustrator" ("PIC") format and not the 62 sector "Micro Painter" raw-images: Boot the attached ATR in Basic. RUN "D:PICLOAD.BAS" after MC initialization and prompt enter D:LADY.PIC for a demo picture. The code is a bit longer than necessary for XL/Es, since it "creates" "GRAPHICS 31" from "GRAPHICS 24" which wasn't available on the old 800 machines (lines 1000-1050). The machine code is relocatable and in a string, so "Page 6" is still free! 5 REM * Micro Illustrator Bildlader 6 REM * in BASIC 7 REM * Peter Blinzer '86 10 DIM FN$ (15):GOSUB 32000:GOSUB 1000:POKE 106,PEEK (106)-34 20 TRAP 40000: TRAP 20: GRAPHICS 0:?

+CharlieChaplin Posted October 20, 2017 Share Posted October 20, 2017 The fun (?) thing about Koala / Micro-Illustrator pictures is that they can be found in three variants: - vertically compressed (smaller than 62 sectors) - horizont(ic)ally compressed (smaller than 62 sectors) - uncompressed (length with 26 Bytes Koala header = 63 sectors) Most Koala/Micro-Illustrator programs do however only support one of these variants when loading or saving. Which variant is used can be found in the 26 Byte Koala header, byte 7 to be exact (zero = uncompressed, 1 = vertical, 2 = horizontal). Luckily there are some picture converters from Antic or Analog that support at least all three variants when loading (by Charles Jackson afair). Vertical compression is mostly used (by Atari Artist, Koala, etc. since it is the best most of the time), but there are programs (e.g. the PD program Pixel Artist Deluxe) that save Koala with horizontal compression and pict. converters (e.g. Rapid Picture Converter) that save Koala without compression.
