推荐答案

我最好的建议是:远离像素图形，尤其是在工程图的情况下.您可以轻松地以惊人的速度渲染矢量模型的图像.如果使用WPF，这特别容易；在这种情况下，您无需担心渲染，缩放，平移-所有这些都已经为您完成.

很少有其他想法:您可以使用开源Incskape创建/使用SVG图形并将其转换为XAML，请参见 http://en.wikipedia .org/wiki/Inkscape [ ^ ]， http://www.inkscape.org/ [

My best advice would be: go away from pixel graphics, especially if this is engineering chart. You can easily render the image our of vector model with blazing speed. It is especially easy if you use WPF; in this case you won''t need to take care about rendering, zoom, panning — all this is already done for you.

Few more ideas: you can create/use SVG graphics and convert it to XAML using open-source Incskape, see http://en.wikipedia.org/wiki/Inkscape[^], http://www.inkscape.org/[^], and you can use XAML in your product during design-time and run-time. You can even allow your user the create custom image in XAML and include them on your charts during run-time; and this is easy to achieve. You actually don''t even need to know XAML format to do that.

How about that?

这应该让您忙一会儿:

"C#图片"的Google几乎有5千1百万个Google搜索结果 [

This should keep you busy for a while:

Almost 51 MILLION google results for "C# images" [^]
