Hovenbitzer | Hello together,
me erdrückt straight a gigantic Wissenslücke what about me hope your can me help on. 
target is it, one Image To loading, it to a Thumbnail To verkleiner and then in a data base to take off.
my trouble is now the part between Thumbnail and Database and there the, How I a Speicheradresse / aray the Bildes and which Size come: 
as Presentation have I the geile GDI+ demonstration of Andreas taken.
$H \windows.ph
$H \includes\Functions_GDIPLUS.ph
$H \includes\GDIP_Imageging.ph
$I \includes\GDIP_Helper.inc
Declare gdiplusToken&,ImageObject&,ImageWidth&,ImageHeight&,GraphicObject&
Declare hPic&
Declare imgThumb&
Declare lngImage&
Declare hBitmap&
Window 0,0-1024,786
Cls ~GetSysColor(~COLOR_3DFACE)
gdiplusToken& = InitGDIPlus()
hPic& = @Create(hPic,-1,Image.jpg)
~GdipCreateBitmapFromHBITMAP(hPic&,0,@Addr(lngImage&))
~GdipGetImageThumbnail(lngImage&,92,69,@Addr(imgThumb&),0,0)
~GdipCreateHBITMAPFromBitmap(imgThumb&,@Addr(hBitmap&))
DrawPic hBitmap&,50,50;0
here bräuchte I now something, what me a address or aray and which Size determined !!!
WaitInput
DeleteObject hPic&
DeleteObject hBitmap&
~GdipDisposeImage(imgThumb&)
~GdipDisposeImage(lngImage&)
ExitGDIPlus(gdiplusToken&)
End

 | wished time of of my Bmp-File(64x64Pixel) The RGB-values read. the Image has 3 different waagerechte
Farbstreifen(RGB). it come utterly incorrect values 31 0 31, 227 0 227 etc.
though pure RGB-values come should 255 0 0, 0 255 0, 0 0 255 zb.

first comes of course 0 248 0 8x then again 224 7 224 8x and 31 0 31 8x the until schluss.
Zeig time your Ausleseprogramm.

 | | Wohlbemerkt The values imho not stature RGB separate BGR exist. |

|
| playing now in the Test no role, derweil each colour the value 255 particular has. at least must the really with of/ one small Fluctuation seperat rauskommen and not these spending supra. Perhaps is my Aufrufreihenfolge wrong...

which Ausleseprogramm? I habs with your code read.
The Bitmap is with CorelDraw prepares.
Zeig still time your Bitmap. |

E.T. | even (because of yet-not-sleep-can  ) time probiert:
Test1 and Test2.bmp show by me each 255 (remainder 0) for jeweilige colour on (Photoshop and AutoCad). likewise The bmp of Jörg.
The in the o.g. Source used Test.bmp is well not thereby  or has at Upload whom name changed ?? |

| I have now time nachgeschaut and fixes the The dissolution on 16bit run is instead of on 32bit.
I knows not yet which Program the affect.
me fell now, that I The Window in the Vollbildmodus move can instead of in the Rändermodus, though I before on Rändermodus went on the Grafikkarte. there have I then too fixes thats on 16bit stood.
