DllStructCreate & $WM_CAP_SET_VIDEOFORMAT

**eukalyptus**

Hallo

diesmal kämpfe ich mit einem sehr komlizierten problem:

ich will die auflösung meiner webcam via script ändern.
lt microsoft geht das mit WM_CAP_SET_VIDEOFORMAT:

Code

WM_CAP_SET_VIDEOFORMAT 
wParam = (WPARAM) (wSize); 
lParam = (LPARAM) (LPVOID) (psVideoFormat);


psVideoFormat = Pointer to a BITMAPINFO structure.

BITMAPINFO

Code

typedef struct tagBITMAPINFO { 
  BITMAPINFOHEADER bmiHeader; 
  RGBQUAD          bmiColors[1]; 
} BITMAPINFO, *PBITMAPINFO;

BITMAPINFOHEADER

Code

typedef struct tagBITMAPINFOHEADER{
  DWORD  biSize; 
  LONG   biWidth; 
  LONG   biHeight; 
  WORD   biPlanes; 
  WORD   biBitCount; 
  DWORD  biCompression; 
  DWORD  biSizeImage; 
  LONG   biXPelsPerMeter; 
  LONG   biYPelsPerMeter; 
  DWORD  biClrUsed; 
  DWORD  biClrImportant; 
} BITMAPINFOHEADER, *PBITMAPINFOHEADER;

Alles anzeigen

RGBQUAD

Code

typedef struct tagRGBQUAD {
  BYTE    rgbBlue; 
  BYTE    rgbGreen; 
  BYTE    rgbRed; 
  BYTE    rgbReserved; 
} RGBQUAD;

ich hab das jetzt mal so probiert:

**BugFix**

Mir ist $tagRGBQUAD nicht ganz klar.
Laut Definition muß $tagBITMAPINFOHEADER als letzten Parameter dword RGBQuad enthalten.

Zitat von BugFix

Mir ist $tagRGBQUAD nicht ganz klar.

Du meinst sicherlich die $tagBITMAPINFO !?!

Die enthält einmal die Struktur $tagBITMAPINFOHEADER und die $tagRGBQUAD

Code

typedef struct tagBITMAPINFO { 
  BITMAPINFOHEADER bmiHeader; 
  RGBQUAD          bmiColors[1]; 
} BITMAPINFO, *PBITMAPINFO;

... oder was meinst Du ?

Sehe gerade in deiner Sigi das Bit-Tutorial ..., Danke dir, sowas habe ich gesucht.

Im 'C++ Primer' wird das zwar auch Erklärt, aber manchmal ist das Buch für mich etwas zu kompliziert ...

**eukalyptus**

erstmal danke für die hilfe (hab eigentlich gar nicht erwartet, daß ich für dieses problem antworten erhalte;)), leider will sich der erfolg noch nicht einstellen.

hab momentan leider keine zeit zum testen und probieren, da ich z.z. etwas im streß bin...

trotzdem mal dankeschön!
