使用位图作为绘制对象的android绘制 [英] android paint using bitmaps as a paint object

问题描述

我正在构建绘图应用程序，并且想创建自定义画笔.我假设有一种方法可以设置您的android.graphics.Paint对象，使其沿路径使用位图而不是颜色，但这似乎并非如此.我想我可以保存路径并为其绘制位图，但这似乎过多..在我开始尝试提出自定义解决方案之前，我想知道是否有人已经解决了这个问题.这个想法是说我有一个星形"图标，ID的意思是能够根据笔划宽度到用户绘制的路径绘制一行星形.

I am building a drawing app and would like to create custom brushes. I assumed there was a way to set your android.graphics.Paint object to use a bitmap along the path instead of a color, but this doesn't seem to be the case.. I suppose i could just save the path and draw bitmaps to it, but that seems excessive.. before i start trying to come up with a custom solution i was wondering if anyone has already tackled this. The idea is lets say i had a 'star' icon, id like to be able to draw a line of stars based on stroke width to the path the user has drawn..

伪代码:

drawPath = new Path();
drawPaint = new Paint();
//drawPaint.setColor(paintColor);
drawPaint.setBitmap(bitmap); /// <-- wouldn't that be sweet

推荐答案

Nevermind ..我找到了..我知道我可以做到..

Nevermind.. i found it.. i knew i could do this..

drawPaint.setShader(new BitmapShader(bm, Shader.TileMode.REPEAT, Shader.TileMode.REPEAT));
