Graphic library

GRF

Graphic library for Colour Maximite 2 computer. It enables simpler use of some graphic formats

Info and loaders for following formats:
General : JPG, GIF, PNG, BMP
Atari ST : PI1, PI2, PI3, PC1, PC2, PC3
C64 : DD, HED, KOA, HBM
ZX Spectrum: SCR, BSC
Also can save BMP in 8- and 16-bit colors.

FUNCTION GRF.getLuma(x AS INTEGER, y AS INTEGER, pg AS INTEGER) AS INTEGER

• return luma of pixel(x, y, pg), 0-255

FUNCTION GRF.info(pg AS INTEGER) AS STRING

• return MODE, BPP, y-lines, pg address, write address

SUB GRF.saveBMP(filePath AS STRING, xx AS INTEGER, yy AS INTEGER, ww AS INTEGER, hh AS INTEGER, pp AS INTEGER)

• save BMP file from screen memory on xx,yy with size of ww,hh from page pp
• it takes bpp from current MODE (so either 8 or 16) = makes BMP smaller than MMBASICs 24bpp

FUNCTION GRF.getImgInfo(filePath AS STRING) AS STRING

• return info about graphic file
• WIDTH, HEIGHT, BPP, VERSION

FUNCTION GRF.loadImg(filePath AS STRING, xx AS INTEGER, yy AS INTEGER, pg AS INTEGER, prog AS INTEGER) AS INTEGER

• load image to x, y, page
• optional prog will show progress bar
• returns 0 when NOK

FUNCTION GRF.getC64info(filePath AS STRING) AS STRING

• get info for some C64 formats

FUNCTION GRF.loadC64(filePath AS STRING, x AS INTEGER, y AS INTEGER, pg AS INTEGER, prog AS INTEGER) AS INTEGER

• load some C64 formats to x, y, page
• optional prog will show progress bar
• returns 0 when NOK

FUNCTION GRF.getCMMcolor(n AS INTEGER) AS INTEGER

• get color from standard CMM (for sprites)

FUNCTION GRF.getZXinfo(filePath AS STRING) AS STRING

• get info for some ZX formats

FUNCTION GRF.loadZX(filePath AS STRING, x AS INTEGER, y AS INTEGER, pg AS INTEGER, prog AS INTEGER) AS INTEGER

• load some ZX Spectrum formats to x, y, page
• optional prog will show progress bar
• returns 0 when NOK

FUNCTION GRF.getSTinfo(filePath AS STRING) AS STRING

• get info for some Atari ST formats

FUNCTION GRF.loadST(filePath AS STRING, x AS INTEGER, y AS INTEGER, pg AS INTEGER, prog AS INTEGER) AS INTEGER

• load some Atari ST formats to x, y, page
• optional prog will show progress bar
• returns 0 when NOK

VERSION HISTORY

v0.12
