Scale, Rotate, Skew and Transform Images using GDI+

GDI+'s image rendering is considerably more powerful than the basic bitmap transfer functions provided under GDI. You can perform high-quality rotation, scaling and skewing with no additional lines of code: and better still the functions run very fast on half decent machines.

Reading EXIF and Other Image Properties Using GDI+

Many digital cameras record information about when and how a picture was taken using the EXIF format (which is slowly becoming the DCF format under ISO). You can read and write this information using GDI+; not just that but you can also read the image metadata from TIF and PNG files.

Reading and Writing JPG, PNG, TIF and GIF Files

This article demonstrates using GDI+ to read and write files in multiple formats (JPEG, PNG, TIF, GIF and BMP files are all supported for reading and writing; you can also read EMG, WMF and ICO files).

Using GDI+ is a great alternative to using the Intel JPEG Library that is now no longer distributed or supported by Intel, since GDI+ is freely redistributable. Not just that but you gain PNG, GIF and TIF support too!

GDI+ Wrapper

The GDI+ Wrapper project is a DLL that works on top of Dana Seaman's excellent GDI+ Type Library and aims to provide COM applications with a wrapper providing equivalent functionality to the C++ and .NET GDI+ classes.

The current version provides support for Images and Bitmaps. Further contributions to the library are encouraged!
