Hello
I need to know how to convert a jpeg stream to bitmap. It will be used for
IpCam.
The picturebox that displays the jpeg is loading only from bitmaps image.
fromhbitmap.
Thanks
Eli

if it is the JPEG image, you can use imaging APIs.
Note:
Imaging APIs are COM objects.
Following Procedure helps you in creating the Bitmap.
1) call IImagingFactory::CreateImageFromFile () to get the IImage interface
from the jpg file.
2) pass the IImage to
IImagingFactory::IImagingFactory::CreateBitmapFromImage () to get the
IBitmapImage inteface.
3) Call the IBitmapImage::LockBits() to get the BitmapData struture.
BitmapData.scan0 is the data
bytes.
4) Create a BITMAPINFO structure and pass this with BitmapData.scan0 to
StretchDIBits() to draw on screen.
Hope this will give you an idea to draw the JPEG image.
