问题描述
嗨我可能会使用Graphics.DrawImage在Graphics上绘制可用的图像.但是我想制作一个在图形上绘制线条，矩形，文本等无法使用的图像.在C#中怎么可能?
在C ++中，可以创建一个与窗口DC兼容的位图，并创建一个与窗口DC兼容的dc，称为内存DC，然后在内存dc中选择位图.在选定的位图上进行进一步的图形操作.然后我有一个CBitmap对象，其中包括已制成的形状.
现在在C#中我该怎么做?
目的是将绘制的形状保存到文件中.
thx
解决方案
hii may use Graphics.DrawImage to draw an available Image on a Graphics. but i want to make an Image which is not available by drawing lines, rectangles, texts, etc. on a Graphics.
how is it possible in C#?
in C++, it''s possible to create a bitmap which is compatible with the window DC and creating a compatible dc with the window DC called memory DC and selecting the bitmap in the memory dc. further graphical operations are done on the selected bitmap. then i have a CBitmap object which includes the made shape.
now in C# how can i do that?
the aim is to save a drawn shape to a file.
thx
