GDI+ - bitmap converting
#1
Hello Gint

Im running code below from a toolbar to capture certain windows.

Macro Macro
Code:
Copy      Help
int hwnd=win
;
RECT r; GetClientRect hwnd &r
POINT p; ClientToScreen hwnd &p

__MemBmp mb
mb.Create(r.right r.bottom 1 p.x p.y)
;
_s="new_img"
if(OpenSaveDialog(1 _s "Image files[]*.bmp[]All Files[]*.*[]" ".bmp"))
,SaveBitmap mb.bm _s
,run _s

I was wondering if we can save the file in other format eg. .jpg by using GDI+ functions?

Only way i could work out so far is create the bitmap file - save bitmap file - convert to jpeg - delete bitmap file.

Can we convert from variable before saving .bmp file or need to save file first?

Thank you.

Searching color from images

The QM GDI+ functions did not have a function to create GDI+ bitmap object from GDI bitmap hanle. You'll find it there.

_s="new_img"
if(OpenSaveDialog(1 _s "JPG files[]*.jpg[]All Files[]*.*[]" ".jpg"))
,GdipBitmap im
,if(!im.FromHBITMAP(mb.bm)) end "error"
,if(!im.Save(_s)) end "error"
