In Form C, when you draw a circle, there are always rectangular teeth around it, how do you eliminat

GDI is like this, you can use any of the following methods I provide to alleviate this problem. 1. Before drawing this circle, draw a blue circle with a slightly lighter color, with a radius larger than your circle, so as to achieve the effect of blurring the edges, and add more circles (but the more the circle drawn before must have a slightly larger radius than the radius of the circle behind, and the color is slightly lighter), the better the effect. 2. Using WPF, this is not GDI but based on DX, which is more exquisite.

3. Direct MDX drawing, a bit of a killing knife feeling. If you're just wondering why it's jagged, then I've got you, and if you're very graphically oriented, I suggest you ditch GDI and learn other graphics frameworks.

Draw in the paint of the form, and you can draw it directly with the graphics in the e passed in the event.

Please refer to the GDI+ technology in C technology, which has a detailed introduction, any book about C has it, you can just check it. Or don't go to the CSDN forum and have it.

the color you want);

What do you say winfrom? This can be done with artboards in Winfrom, and if you want to load them at load time, you need to know the serialization and deserialization operations in C.

Do you want to display a picture or draw on the interface Similar to the "Paint" that comes with Windows?

Each widget has a way to get the canvas, just use a brush or brush to paint on the canvas. In addition, if you want to still see ** when the form is redisplayed, you need to write the ** of the drawing in the redraw method of the form.

It is most convenient to replace the whole two **.

First, set the form's transparencykey to a special color, such as green.

Then in the paint event of the form, it is handled like this, for example:

graphicspath mypath = new graphicspath();

new rectangle( 0,0, 40,40 ),180f, 90f );

mypath );
