Hi guys,
I am writing a imaging aplication on VC++.I have to display images and
apply effects onto it.Images could be of any type like jpg,gif,bmp,psd...M
uding createDibSection API.it requires BITMAPINFO struc as one of its
parameters.Its working well(Images are successfully displayed) but my
problem is that in certain images(of any type)they are skewed and becomes
B/W(means Data corruption).U can see my code of populating BITMAPINFO and
CreateDibSection...Can any body help me in solving the annoying probs.
[Note:If I am changing the dimension of image by few pixels using
photoshop it displays well]
BITMAPINFO bmi;
bmi.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
bmi.bmiHeader.biBitCount = 24; bmi.bmiHeader.biWidth
= swidth;//Image width
bmi.bmiHeader.biHeight = -sheight;//Image Height //
neg for top-to-bottom
bmi.bmiHeader.biPlanes = 1;
bmi.bmiHeader.biCompression = BI_RGB; // uncompressed
bmi.bmiHeader.biSizeImage = 0; // unused for BI_RGB
bmi.bmiHeader.biXPelsPerMeter = 0;
bmi.bmiHeader.biYPelsPerMeter = 0;
bmi.bmiHeader.biClrUsed = 0;
bmi.bmiHeader.biClrImportant = 0;
bmi.bmiColors[0].rgbBlue = 0;
bmi.bmiColors[0].rgbRed = 0;
bmi.bmiColors[0].rgbGreen = 0;
bmi.bmiColors[0].rgbReserved = 0;
hBmp = CreateDIBSection( hdc_
, &bmi
, DIB_RGB_COLORS
, &imageBuff //pointer to created buf
, NULL
, 0);
dcMem = ::CreateCompatibleDC(hdc_);//creates a memory compatible
device context (DC)passing exixting DC
(HBITMAP) ::SelectObject(dcMem, hBmp); //selects handle of image to
Device
//context dcMem
