Using Windows Stock Icons in Delphi it is not a big discovery that all applications are running in the environment provided by the underlying operating system. Delphi is well-known for its rapid application development capabilities. The latest version of Delphi - Delphi 2010 - is the first release to support Windows 7, with all its latest and hottest additions including touch, multi-touch, gesturing and Direct2D. The Windows operating system is implemented in native C++ code and Delphi 2010 can directly leverage all its features w...
Converting to grayscale with TBitmap.ScanLine property In my previous post "Boian’s TBitmap Visualizer and converting to grayscale" I have described an algorithm for converting arbitrary TBitmap instances to gray using a selected formula. The problem is with the performance of the code that actually changes the color of each pixel. Accessing color information is done via TBitmap.Pixels property, which is a two-dimensional array of TColor values. Since Delphi 3 there is a more efficient way of manipulating color information - using TBitmap.Scanline p...
Boian's TBitmap Visualizer and converting to grayscale Debugger Visualizers introduced in RAD Studio 2010, for both Delphi 2010 and C++Builder 2010, are one of the most interesting new IDE features. On the ITDevCon 2009 Delphi conference in Verona I have met Boian Mitov from Mitov Software, who actually wrote a sample "TBitmap" visualizer for Delphi 2010. Boian has architected lots of VCL components for all kinds of signal processing, including advanced video and audio processing implementation. Very cool and sophisticated stuff demonstrating the po...

Delphi 2010 DirectWrite "Hello World" Example In my previous post I have translated Windows 7 SDK Direct2D "Advanced Geometries" example from C++ to Delphi 2010 code. That was a lot of fun, so I have decided to continue the adventure in the realm of Direct2D programming and this time converted one of the DirectWrite examples - DirectWrite sample "Hello World". [caption id="attachment_38873" align="alignnone" width="300" caption="Delphi 2010 Hello World DirectWrite sample app"][/caption] In order to avoid writing over and over again th...
Direct2D "Advanced Path Geometries" Win7 SDK Example Translated to Delphi 2010 In two days I'm talking about Windows 7 development at Delphi 2010 HandsOn Workshop with Bob Swart and Bruno Fierens from TMS Software. One of the cool new features introduced in Delphi 2010 specifically for Windows 7 is support for native Direct2D development. Direct2D is very interesting, new graphics subsystem that utilizies GPU processing power for rendering regular operating system windows. Because of the performance considerations Direct2D has been implemented in native code in Windo...

ITDevCon 2009 - Day 2 It is the second day of ITDevCon. The conference is really better than I was expecting. bitTime crew is taking perfect care of all attendees. Again - it is impossible to be on three parallel sessions at the same time. Especially if you are delivering sessions yourself:-) The first session for me was my "Delphi Natural Input" session. I have covered Delphi 2010 support for touch, multitouch and gesturing. The more I go into this technology the more I like it. In order to demo multitouch you re...
