These files have been moved to:
|

|

This directory contains 8bitworkshop tools for bitmap and
|
||||
music conversion.
|
||||
|
||||
Requires ImageMagick (convert) and Python 2.x.
|
||||
MIDI tools require Mido (pip install mido).
|
||||
|
||||
On Ubuntu:
|
||||
|
||||
$ sudo apt update
|
||||
$ sudo apt install python python-pip imagemagick curl
|
||||
$ sudo pip install mido
|

TMSOPT v.0.1 - Eduardo A. Robsy Petrus & Arturo Ragozini 2007
|
||||
Credits to Rafael Jannone for his Floyd-Steinberg implementation
|
||||
---------------------------------------------------------------
|
||||
TGA image converter (24 bpp, uncompressed) to TMS9918 format
|
||||
---------------------------------------------------------------
|
||||
Overview
|
||||
---------------------------------------------------------------
|
||||
Selects the best solution for each 8x1 pixel block
|
||||
Optimization uses the following algorithm:
|
||||
|
||||
(a) Select one 1x8 block, select a couple of colors, apply
|
||||
Floyd-Steinberg within the block, compute the squared error,
|
||||
repeat for all 105 color combinations, keep the best couple
|
||||
of colors.
|
||||
|
||||
(b) Apply Floyd-Steinberg to the current 1x8 block with the best
|
||||
two colors seleted before and spread the errors to the
|
||||
adjacent blocks.
|
||||
|
||||
(c) repeat (a) and (b) on the next 1x8 block, scan all lines.
|
||||
|
||||
(d) Convert the image in pattern and color definitions (CHR & CLR)
|
||||
|
||||
To load in MSX basic use something like this:
|
||||
|
||||
10 screen 2: color 15,0,0
|
||||
20 bload"FILE.CHR",s
|
||||
30 bload"FILE.CLR",s
|
||||
40 goto 40
|
||||
|
||||
---------------------------------------------------------------
|
||||
Compilation instructions
|
||||
---------------------------------------------------------------
|
||||
Tested with GCC/Win32 [mingw]:
|
||||
|
||||
GCC TMSopt.c -oTMSopt.exe -O3 -s
|
||||
|
||||
It is standard C, so there is a fair chance of being portable!
|
||||
NOTE
|
||||
In the current release the name of the C file has become scr2floyd.c
|
||||
---------------------------------------------------------------
|
||||
History
|
||||
---------------------------------------------------------------
|
||||
Ages ago - algorithm created
|
||||
16/05/2007 - first C version (RAW format)
|
||||
17/05/2007 - TGA format included, some optimization included
|
||||
18/05/2007 - Big optimization (200 times faster), support for
|
||||
square errors
|
||||
19/05/2007 - Floyd-Stenberg added, scaling for better rounding
|
||||
24/05/2007 - Floyd-Stenberg included in the color optimization.

TMSOPT v.0.1 - Eduardo A. Robsy Petrus & Arturo Ragozini 2007
|
||||
Credits to Rafael Jannone for his Floyd-Steinberg implementation
|
||||
---------------------------------------------------------------
|
||||
TGA image converter (24 bpp, uncompressed) to TMS9918 format
|
||||
---------------------------------------------------------------
|
||||
Overview
|
||||
---------------------------------------------------------------
|
||||
Selects the best solution for each 8x1 pixel block
|
||||
Optimization uses the following algorithm:
|
||||
|
||||
(a) Select one 1x8 block, select a couple of colors, apply
|
||||
Floyd-Steinberg within the block, compute the squared error,
|
||||
repeat for all 105 color combinations, keep the best couple
|
||||
of colors.
|
||||
|
||||
(b) Apply Floyd-Steinberg to the current 1x8 block with the best
|
||||
two colors seleted before and spread the errors to the
|
||||
adjacent blocks.
|
||||
|
||||
(c) repeat (a) and (b) on the next 1x8 block, scan all lines.
|
||||
|
||||
(d) Convert the image in pattern and color definitions (CHR & CLR)
|
||||
|
||||
To load in MSX basic use something like this:
|
||||
|
||||
10 screen 2: color 15,0,0
|
||||
20 bload"FILE.CHR",s
|
||||
30 bload"FILE.CLR",s
|
||||
40 goto 40
|
||||
|
||||
---------------------------------------------------------------
|
||||
Compilation instructions
|
||||
---------------------------------------------------------------
|
||||
Tested with GCC/Win32 [mingw]:
|
||||
|
||||
GCC TMSopt.c -oTMSopt.exe -O3 -s
|
||||
|
||||
It is standard C, so there is a fair chance of being portable!
|
||||
NOTE
|
||||
In the current release the name of the C file has become scr2floyd.c
|
||||
---------------------------------------------------------------
|
||||
History
|
||||
---------------------------------------------------------------
|
||||
Ages ago - algorithm created
|
||||
16/05/2007 - first C version (RAW format)
|
||||
17/05/2007 - TGA format included, some optimization included
|
||||
18/05/2007 - Big optimization (200 times faster), support for
|
||||
square errors
|
||||
19/05/2007 - Floyd-Stenberg added, scaling for better rounding
|
||||
24/05/2007 - Floyd-Stenberg included in the color optimization.
