QT Graphics (simple strokes-draw cartoon ants)

Briefly

About the introduction of a lot of strokes, there are animals, fruits, vegetables, transportation, etc., usually to draw a step by step to split, combination. Then draw the results as we want.

Here's another category: Insect-cartoon ants.

Drawing effect

The specific effect is as follows, and we can do a better job of improving it.

Source

Mainly divided into the following three parts:

• Draw Butt
• Draw Belly
• Draw Head

Note: When drawing, due to the different colors of the various parts, and the coordinates are not good positioning, so we use the way the graphics overlay.

void MainWindow::p aintevent (qpaintevent *) {qpainter painter (this);Painter. Setrenderhint(Qpainter:: antialiasing, True);    /***** Butt *****/Qpainterpath Path;Path.

For the general drawing is relatively simple, because it is commonly used, regular, and comparative rules, such as circles, ellipses, rectangles, straight lines. If there are a variety of complex graphics, then the original drawing scheme is difficult to achieve, it takes a lot of time to toss back and forth, so here is no longer introduced.
