需要有关使用WPF启动栅格绘图程序的建议 [英] Need an advice about starting a raster drawing program with WPF

问题描述

很抱歉打扰您这个菜鸟问题！
我想开始为WPF编写一个简单的光栅绘图程序，该程序带有图层等(例如paint.net)作为学习项目. .
您对我应该从哪里开始有什么想法?我曾尝试找到类似的项目来寻找有关Google的想法，但我做不到.
哪些组件和基类适合尝试?

I''m sorry about bothering you with such noob question!
I''d like to start programming a simple raster drawing program for WPF with layers, etc. (something like paint.net) as a learning project.
Do you have any ideas where should I start? I''ve tried to find similar projects to look at for ideas on google but I couldn''t.
What components and base classes are suitable to try?

推荐答案

WPF用于矢量图形，不适用于位图.

如果要在WPF中显示位图，并且需要能够在内存中有效地更新位图，请查看 RenderTargetBitmap [ ^ ]

WPF is meant for vector graphics, not for bitmaps.

If you want to display a bitmap in WPF and need to be able to efficiently update it in memory, look at the WriteableBitmap[^] class.

If you want to render WPF vector contents onto a bitmap, take a look at RenderTargetBitmap[^].

你好，

为丹尼尔·格伦瓦尔德("Daniel Grunwald")鼓掌，恕我直言，他对OP进行了体贴和适当的回应.

仍然，恕我直言，他以某种救赎"的幽默感回应了JSOP的第一个剑杆斜线.

我对所有(imho)讽刺和不必要的帖子#1进行了投票:这是一个技术论坛，而不是休息室！我只是出于纯粹的矛盾而对OP进行了投票.

先生们，先生们，我想问一下，使用技术论坛作为人际静态的"?

礼貌地告诉OP，问题过于广泛，以至于无法论题，无法回答或暗示，这是否更有价值(我是在用口头表达)向OP寻求有关CP的许多技术文章，这些文章涉及WPF和WinForms中的绘图，绘图表面，位图，形状等? 天真":建议您照照镜子:)

最好，比尔

Hello,

"Applause" for Daniel Grunwald, who, imho, gave a considerate and appropriate response to the OP.

Given the OP''s question was broad enough that you could see the earth''s curvature in the distance ...

Still, imho, he responded with some "redeeming" sense of humour to the first rapier slash of JSOP.

I''ve voted all the (imho) sarcastic and needless posts #1 : this is a technical forum, not the lounge! And I''ve voted up the OP just for the sake of sheer contrariness.

Gentlemen and Gentlewomen, I ask you whether it benefits CodeProject as a whole to use the technical forums as a "dumping ground" for "interpersonal static" ?

Isn''t it more valuable (I''m asking rhetorically) to just politely tell the OP that the question is so broad as to be off-topic, or unanswerable, or to suggest to OP that they do a search of the many technical articles on CP that have to with drawing, drawing surfaces, bitmaps, shapes, etc. in both WPF and WinForms ?

To those of you who wish to admire your "godliness" : I suggest you look in a mirror :)

best, Bill
