How can I (example code if possibel Smile )

I want a small program that will run in the top corner of the screen, when i mouse the mouse anywhere on the screen.

I want my program to display the mouse position and the pixel colour ?

I have tried doing a printscreen then using tommys vdsdll.dll to load the bitmap and then use @dll(pixel) but it is very slow and not reiable.

Any help

Nathan

Hi Nathan,

I think you tried to use the VDSIMAGE part of the VDSDLL 3. The VDSCAP DLL
contains a pixel function too which returns the color of a specified screen coordinate.
I think that one may work for your purposes.

The following code assumes that you are using the vdscap.dll. Color
conversions provided are RGB, VDS, HTML, CHEX and LONG.

-Garrett

Code:
  %%Color0 = @capture(Pixel,@mousepos(x),@mousepos(y))
  Gosub Convert
  %%vdscolor = @sum(%%Color,0)
  %%hex = @hex(@diff(%%vdscolor,0),8)
  %%blue = @sum($@substr(%%hex,3,4),0)
  %%green = @sum($@substr(%%hex,5,6),0)
  %%red = @sum($@substr(%%hex,7,8),0)
  %%HtmColor = #@hex(%%red,2)@hex(%%green,2)@hex(%%blue,2)
  %%CHex = 0x@hex(%%blue,2)@hex(%%green,2)@hex(%%red,2)
  %%Long = @sum($%%hex,0)
   Goto EventLoop


:Convert
  If @equal(%%Color0,red)
    %%Color = $000000FF
  ElsIf @equal(%%Color0,black)
    %%Color = $00000000
  ElsIf  @equal(%%Color0,white)
    %%Color = $00FFFFFF
  ElsIf  @equal(%%Color0,dkred)
    %%Color = $00000080
  ElsIf  @equal(%%Color0,dkgreen)
    %%Color = $00008000
  ElsIf  @equal(%%Color0,brown)
    %%Color = $00008080
  ElsIf  @equal(%%Color0,dkblue)
    %%Color = $00800000
  ElsIf  @equal(%%Color0,magenta)
    %%Color = $00800080
  ElsIf  @equal(%%Color0,gray)
    %%Color = $00808080
  ElsIf  @equal(%%Color0,silver)
    %%Color = $00C0C0C0
  ElsIf  @equal(%%Color0,ltgreen)
    %%Color = $0000FF00
  ElsIf  @equal(%%Color0,yellow)
    %%Color = $0000FFFF
  ElsIf  @equal(%%Color0,ltblue)
    %%Color = $00FF0000
  ElsIf  @equal(%%Color0,cyan)
    %%Color = $00FFFF00
  Else
    %%Color = $00@hex(%%Color0)
  End
  Exit

Just a note...

VDS uses a reversed color format (BBGGRR), HTML
uses standard RRGGBB format. Wink

Sorry, I lack commenting source code. Especially when I just grab the
code from something that wasn't an example.
