CreateDIBSection from GDI32?

[gregory_may]

I cant seem to find good GDI32 function prototype for CreateDIBSection.

Anyone know where I can find them?

This is the best I can find:
http://www.microsoft.com/japan/windowsxp/tabletpc/using/devtips/save_saveas.asp

But, the BITMAPINFO_STRUCT is missing.



Also, an example of working with CreateDIBSection and BitBlt would be a nice
bonus if anyone has one.

Hello,

where do i find the correct definition for:
BITMAPINFO

Try this:

~
<StructLayout(LayoutKind.Sequential)> Friend Structure BitmapInfo
Public bmiHeader As BitmapInfoHeader
<MarshalAs(UnmanagedType.ByValArray, SizeConst:=1)> Public
bmiColors() As RGBQuad
End Structure

<StructLayout(LayoutKind.Sequential)> Friend Structure
BitmapInfoHeader
Public biSize As Integer
Public biWidth As Integer
Public biHeight As Integer
Public biPlanes As Short
Public biBitCount As Short
Public biCompression As Integer
Public biSizeImage As Integer
Public biXPelsPerMeter As Integer
Public biYPelsPerMeter As Integer
Public biClrUsed As Integer
Public biClrImportant As Integer
End Structure

<StructLayout(LayoutKind.Sequential)> Friend Structure RGBQuad
Public rgbBlue As Byte
Public rgbGreen As Byte
Public rgbRed As Byte
Public rgbReserved As Byte
End Structure
~

I hope it helps
