sbox - the smart bordered box (may 21,2016)
Post by michael on May 20th, 2016, 02:13am

The command:
sbox(x,y,h,v)
x,y the first coordinates.. (somewhere on the screen)
h,v the second set of coordinates (somewhere on the screen)

It doesn't matter where the coordinates are on the screen, it will always draw a proper bordered box
Code:
      REM       width;height;charwidth,charheight,number of colors,character set
      VDU 23,22,1024;600;8,15,16,1 :REM max width is 1920 and 1440 height
      REM Turn off the text cursor _
      OFF
      VDU 5 : REM Treat text as graphics (transparent background)
      REM block(x,y,h,v) --- Always have the lower left corner a lesser number than the last 2 coordinates
      PROCsbox(100,100,500,500)
      PROCsbox(800,800,500,500)
      PROCsbox(0,1000,500,500)
      REM pr(x,y,"message",R 0-255,G 0-255,B 0-255)

Re: Border box tool and improved text tool+ideas

Hi Michael,

I made these routines when I was thinking about the colour picker problem. Are they any use?

PROCReadPalette and PROCReadPaletteN needs a 1 dimensional array big enough to hold the N colours you want to read: typically 16 (0-15) for the "normal" colours you can set with COLOUR. This is useful to capture the default palette before you start messing around with the colours - but you could also use it to store the current position before altering it in one of your subroutines. The version without an N reads 16 entries; the N variant allows you to read however many you like.

PROCSetPalette and PROCSetPaletteN take the resulting array and set the palette to the stored colour numbers. The version without an N sets 16 entries; the N variant allows you to set however many you like.

PROCSetGreyScale fills an array with an even grey scale, which you can then pass to PROCSetPalette.

PROCSetDefaultColours fills an array with the default colour numbers, which you can then pass to PROCSetPalette. I just ran PROCReadPalette and wrote down the output...

PROCChooseColour I think you've seen before. It's here so you can modify the palette entries and then redisplay, to check it's all working correctly.

Best wishes,

D

Code:
      DIM pal%(15),greys%(15)
      PROCReadPalette(pal%())
      PROCShowPalette(50,50)
      PROCSetGreyScale(greys%())
      PROCSetPalette(greys%())
      PROCShowPalette(50,100)
      PROCSetDefaultColours(greys%())
      PROCSetPalette(greys%())
      PROCShowPalette(50,150)
      PROCSetPalette(pal%())

I do like your RGB color picker tool. I would like to modify it so that it shows the proper RGB values also.. Ill work on that
