s there any reason to do image processing in unmanaged code anymore? GDI+'s managed classes may just be good enough to give the unmanaged approach (mainly in unmanaged C++) a run for its money. GDI+ classes allow you to read the metadata information stored in images recorded by a digital camera&151;and then resize those images while ensuring image quality. The ImageAttributes and ColorMatrix classes help with color adjustment and the image codecs class specifies the colour depth and quality of the jpeg images.
In this article, you'll learn about GDI+'s enhanced image manipluation capabilities by building a multithreaded, image-resizing tool. Decide for yourself whether it's better!
