Problem with resolution
Posted: 2009-09-05T02:38:30-07:00
Hi all
I'm using magick++.
I'm having a trouble with an image that come from a scanner.
I get a pointer to a HDIB, desume the BITMAPINFOHEADER, then get a pointer to first byte to bitmapbits and call Magick::Image CTOR:
Where getBitmapBits() give me a DWORD* pointer to bitmap bits.
m_bitmapInfoHeader is a member variable of my class in wich i store a pointer to BITMAPINOHEADER (LPBITMAPINFOHEADER) of the HDIB coming from scanner.
If i set a resolution (from scanner) equals to 200x200 then the image is correct.
Instead i i set another resolution (300x300 for example) the image apper inclined.
Can anyone help about this?
Best regards
