Mahesh Chand, author of "Graphics Programming with GDI+", is a .NET
consultant and the founder and administrator of
www.c-sharpcorner.com and
www.mindcracker.com. He has been
working with .NET since the pre-beta releases. His previous books include
two practical books for the programmer interested in ADO.NET: "A
Programmer's Guide to ADO.NET" and "Applied ADO.NET programming". A prolific
writer, Mahesh has also written several articles and tutorials on .NET
related topics, including articles for Visual Studio magazine.
With "Graphics Programming with GDI+", Chand has
written a well-organized, well-written and easy-to-understand tutorial on
the most common features of GDI+. Targeted for the beginning to intermediate
level .NET developer, it covers everything: working with the Graphics Class,
Brushes and Pens, Colors, Fonts and Text, Rectangles and Regions, rendering,
images, image-manipulation, 2D graphics, transformations, printing, GDI for
the Web, and Custom Controls. While most of the sample code in the book is
written in C#, the source code can also be downloaded in VB.NET. This is
also one of the few resources that include coverage of how to read and write
images to a database with ADO.NET.
The book begins with an introduction to GDI+ and the
basics of graphics programming in Windows. For the programmer with a GDI
background, Chand explains the differences between GDI and GDI+. The core of
the book includes a hands-on guide to practical topics, including
interesting and fun examples such as how to develop a GDI+Painter,
GDI+Editor, ImageViewer, and ImageAnimator.
The best features of the book include extensive
coverage of printing in .NET, with over 100 pages devoted to such topics as
printing graphics and images, manipulating printer settings and hard-to-find
coverage of the Print Controller class. Chand explains all the details of
printing in .NET, including topics you won't find on MSDN or in other books.
In addition, this is one of the few places that ASP.NET developers can find
a gentle introduction to GDI+ for Web applications. Chand draws form his
experiences on the c-sharpcorner message boards, and includes a chapter on
GDI+ FAQs, along with tips for optimizing performance and image rendering, a
chapter covering the use of GDI in a managed environment through COM interop,
and a chapter on "Best Practices" with GDI+. This book is also filled with
the kind of sample code which is so often missing from MSDN.
Having said that, those programmers with a strong GDI
background may find the coverage of GDI+ a little thin. There is just a
scant amount of information on such topics as the underlying coordinate
system of GDI+. The book also doesn't discuss how vector shapes in GDI+ get
rendered into pixels, and how this can lead to "off by one pixel" issues.
There is also no discussion on the more subtle issues surrounding metafiles
(for example, when to use an hDC). And while there is an introduction to
animation, it's definitely not heavyweight coverage.
Overall, this book is an excellent reference book on
GDI+ for the beginning to intermediate level .NET developer and is a useful
handbook for anyone who does graphics programming for Windows or Web
applications. And as an interesting FYI, this book is one of the many
excellent .NET books available online at
www.safaribooksonline.com/.
If you are looking for just one book that provides well-rounded coverage of
the entire GDI+ API, purchase or download a copy of "Graphics Programming
with GDI+". |
