Ry transformation is matrix transformation. The matrix of the paint brush ignores Dx and Dy translation parameters. It is better to select linecapround. In this example: Code File: Unit unit1; interfaceuses windows,

Preface: The so-called "stream" refers to a piece of data or a piece of memory;When performing stream operations, we don't have to worry about the data in the stream. We only need to know the stream size and the current pointer position.

This example has an error! The point type is often not single; For example, a point may be a sub-path end point, a curve point, or a mark point at the same time. A type value is a combination of three types. Unfortunately, I still don't know

In delphix, all we can see is drawn in tdxdraw. Tdxdraw has two default drawing surfaces: tdxdraw. Surface and tdxdraw. Primary;Generally, you need to first plot the image on the background (surface), and then use the tdxdraw. Flip command to
