auto clip of desktop image

[ken gray]

Since I cannot have a transparent background on an OnScreenDisplay, I'd like to be able to grab a section of the desktop image (as it shows rather than out of the file itself) and put that into an OSD background so that it 'looks' like its transparent?

I can try to do it on Vista but don't know how on XP.

how about doing it old school on XP with a W+d and grabbing a block of pixels from x y to x2 y2 and saving that to a jpg?

toolbar would not be updated when background changes, for example when you move toolbar

that's ok...I would call the process each time anyway if necessary anyway.

:lol:
wow that is amazing! and it works a lot faster than i thought it would too!

I was looking over the code but can't seem to make sense of it enough to do that for an OSD too. How can I do that?

[Gintaras]

this is without changing system functions
Macro

Code:

str s="text wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww"

;at first show transparent OSD
OnScreenDisplay s 0 0 0 0 0 0 0 "osd_chameleon"
;get its coordinates
int hWnd=win("osd_chameleon" "QM_OSD_Class")
RECT r; GetClientRect hWnd &r
POINT p; ClientToScreen hWnd &p
;capture screen and save bitmap
__MemBmp mb
mb.Create(r.right r.bottom 1 p.x p.y)
SaveBitmap mb.bm "$temp$\osd_chameleon.bmp"
;close
spe; hid hWnd; clo hWnd
;then show another OSD with that bitmap
OnScreenDisplay 0 0 p.x-1 p.y-1 0 0 0 1|128|16 0 0 0 "$temp$\osd_chameleon.bmp"
