VideoHdr to hDC or StdPicture

[Dean Earley]

I'm banging my head against the desk at the moment while studying 8 pages of cDibSection.

I have a video header (or a pointer) and I cant find anyway at all to put it onto an hdc or stdpicture

Any help appreciated

If you have a pointer to the pixel's data ( Gptr) you can tranfer it to a
Device Context.



CoDc = CreateCompatibleDC(0) '
bi.bmiHeader.biSize = 40
bi.bmiHeader.biWidth = cWidth' Your Header Width
bi.bmiHeader.biHeight =cHeight ' Your Header Height
bi.bmiHeader.biPlanes = 1
bi.bmiHeader.biBitCount = 24
bi.bmiHeader.biCompression = BI_RGB


DIBSectionHandle = CreateDIBSection(CoDc, bi, DIB_RGB_COLORS, address,
0, 0)
OldCompDCBM = SelectObject(CoDc, DIBSectionHandle)
' Gptr Your Pointer to Pixel's data

StretchDIBits CoDc, 0, 0, cWidth, cHeight, 0, 0, cWidth, cHeight, ByVal
Gptr&, bi, DIB_RGB_COLORS, vbSrcCopy

' CoDc is now a Device context with your image .

Thanks I'll Try that

Also, is there a recommended way of drawing onto a StdPicture without an associated PictureBox. I think the StdPicture.Handle is a
pointer to a bitmap structure.

Thanks

Hi

I think the StdPicture.Handle is not a pointer.

Anyway the mothods i know to fill a StdPicture object are :

1 - Stpi As StdPicture
Set Stpi = LoadPicture("C:\test.bmp") ' or test.jpg

2 - Or using the Render method of StdPicture object
( Never tried this)

Returns a handle to the graphic contained within a Picture object.

My mistake

Only draws from the StdPicture to an hDc
