MFC Support for Direct2D – Part 2

A previous article shows how to use D2D MFC classes for easily make a simple image viewer. As said there, it can be made even easier. Enabling D2D support in MFC In the WM_CREATE message handler call CWnd::EnableD2DSupport.

In the overridden CView::OnUpdate load the bitmap from the current document’s file.

MFC Support for Direct2D – Part 1

A few time ago, I begun writing a series of wrapper classes to make easier the using of Direct2D interfaces. Meanwhile, I discovered that MFC Library, beginning with Visual Studio 2010 SP1, offers an excelent built-in support. That’s pretty cool! So, let’s use Direct2D (D2D) MFC classes for making a simple image viewer. Image viewer […]

MFC Support for Windows Animation

Let’s say we have to make a slide show presentation using Cross Fade effect. If the target system is Windows 10, that’s quite easy because Direct2D offers built-in Cross Fade effect. Cross Fade effect example

Further we can set a timer to periodically change m_dWeight value from 0.0f to 1.0f. So far, so good but […]

MFC Support for DirectWrite – Part 10: Outlined Text

In a previous article, I showed the basics of custom text rendering with DirectWrite (see MFC Support for DirectWrite – Part 7: A Step to Custom Rendering). So far so good but it just mimics the default text rendering. Let’s now modify the overridden IDWriteTextRenderer::DrawGlyphRun in order to draw outlined text. Overridden IDWriteTextRenderer::DrawGlyphRun implementation

MFC Support for DirectWrite – Part 8: Trimming

When using “classic” GDI functions i.e. CDC::DrawText, it’s no sweat to trim with ellipsis a single-line text when that text does not fit in the drawing rectangle width, by specifying DT_WORDBREAK flag. We cannot find a similar flag for CRenderTarget::DrawText or CRenderTarget::DrawTextLayout. However, trimming a text is also possible with DirectDraw. All we have to […]

Easy PNG Resource Loading with MFC – Part 2

A previous article demonstrates how easy is to load images from PNG resources, by using Direct2D MFC support. I have found even an easier way: CPngImage class which extends CBitmap with methods that allow loading images from PNG format files and resources. Here is a brief example: Using CPngImage class for loading PNG resources

Getting Direct2D, DirectWrite and WIC Factories in MFC

MFC library offers a series of wrapper classes over Direct2D and DirectWrite interfaces (see CRenderTarget and CD2D classes). That’s pretty cool because allows to easily load and render images and draw texts, without care too much of direct dealing with COM interfaces. However, let’s say we have to implemented something different so we need to […]
