 |
|
Hi All
I'm pretty new to c programming, and have a little question.
I'm writing a web-cam application (it's a very long story, but my 'normal'
web-cam software will not work with my capture card).
I have a timer running which will grab a single frame, and then FTP it to my
web-site. This works reliably, but I'm using capFileSaveDIB which produces a
bmp file. Is there an easy way to convert to (or save as) a jpg ?
TIA

Load the DIB into a TBitmap and then Assign() it to a TJPEGImage. For
example:
if( capFileSaveDIB(hCapWnd, "c:\folder\file.bmp") )
{
Graphics::TBitmap *bmp = new Graphics::TBitmap;
try
{
bmp->LoadFromFile("c:\folder\file.bmp");
TJPEGImage *jpg = new TJPEGImage;
try
{
jpg->Assign(bmp);
jpg->SaveToFile("c:\folder\file.jpg");
}
__finally {
delete jpg;
}
}
__finally {
delete bmp;
}
}
