How to load Images from disk to Device context of and SDI MFC application. I want to choose images from existing folder at runtime.
It is probably the easiest to use CImage, see: http://msdn.microsoft.com/en-us/library/bwea7by5(v=vs.80).aspx
It's something like:
void CMyDlg::OnBnClickedOpenImage()
{
CFileDialog dialog(TRUE, NULL, NULL,
OFN_FILEMUSTEXIST | OFN_HIDEREADONLY,
L"Windows Bitmap (*.bmp)|*.bmp|JPEG Compressed Image (*.jpg;*.jpeg)|*.jpg; *.jpeg|PNG Image (*.png)|*.png|All Images (*.bmp;*.jpg;*.jpeg;*.png)|*.bmp; *.jpg; *.jpeg; *.png|All Files (*.*)|*.*||");
if (dialog.DoModal() == IDOK)
{
HDC hDC = pDC->GetSafeHdc();
CImage image;
image.Load(dialog.GetPathName());
image.Draw(hDC, 0, 0);
}
}
Edit: Added the open file dialog.
