A simple decorator to help prevent blurry images and lines

Actipro — Thu, 15 May 2008 19:41:36 GMT

We've recently added a PixelSnapper decorator to the Actipro WPF Shared Library, which helps with pixel alignment by providing options for rounding off decimal measurements of child content to integer numbers instead of decimals. Using the PixelSnapper decorator is an easy way to keep everything crisp and clear in your WPF applications.

Blurry Bitmaps Sample to Data Bound

willlan — Tue, 26 Aug 2008 11:06:47 GMT

This is a great piece of code and worked really well, although I was disapointed when if did not work for data bound items. However after a bit of playing I found that if you inherted from framework element instead and used the MeasureOverride Instead of MeasureCore then it will work.

Thankyou for your great work.

FrameworkElement is the way to go

Thank you, willlan, for posting about changing the base class to FrameworkElement and changing MeasureCore to MeasureOverride. The version deriving from UIElement did not resize if you changed the Source later on to one with a different size than the original. By deriving from FrameworkElement, if you change the Source, it automagically gets remeasured.

I understand Dwayne's instinct to pick UIElement to avoid the possibility of properties like Width getting explicitly set, but deriving from FrameworkElement makes the result much more generally useful.

@Eric. I also needed data binding and so changed the base class from UIElement to FrameworkElement, and MeasureCore to MeasureOverride.

One bug with this implementation is that if you add Margin to the element, the image appears to stretch (even non-uniformly) to fill the margin space too. Still, if you can work around that, it's a nice way to go.

Thanks Dwayne for this post.

I also noticed a problem with the modified code whereby if there's nothing to display, and endless loop can occur, maxing out the CPU. This check guards against this happening:

private void OnLayoutUpdated(object sender, EventArgs e)

{

// Avoid getting into an endless loop

if (ActualHeight == 0 || ActualWidth == 0)

return;
