libgdx- pixmap：我可以以某种方式改变线的宽度吗？ [英] libgdx- pixmap: can I somehow change the width of the line?

问题描述

我想绘制一条线然后生成纹理（使用libgdx）。我发现用pixmap创建圆形，矩形和线条的纹理很简单。
但我没有找到如何设置绘制形状的线宽。
有没有可能设置pixmap的线宽？

I want to draw a line and then generate a texture (with libgdx). I found out that creating a texture from circles, rectangles and lines is simple with pixmap. But I didn't find out how to set the linewidth of the drawn shape. Is there any possibility to set the linewidth for pixmap?

这是我到目前为止的代码：
（我试图绘制两个填充的圈子并用线连接它们）

Here is the code I got so far: (I tried to draw two filled circles and to connect them with a line)

Pixmap pixmap = new Pixmap( 16, 16, Format.RGBA8888 );
pixmap.setColor(Color.BLUE);
pixmap.fillCircle(x1, y1, 10);
pixmap.fillCircle(x2, y2, 10);
pixmap.drawLine(x2, y2, x1, y1); // this line is very thin
Texture pixmaptex = new Texture( pixmap );
pixmap.dispose();

推荐答案

OpenGL实现不能可靠地支持线宽。要绘制胖线，请绘制一个矩形。

Linewidth isn't reliably supported by OpenGL implementations. To draw "fat" lines, draw a rectangle.
