c++GDI+发光子与发光边框画法

[Yun__]

这个是结果
下面是画法
自己包含头文件

问题是。。 我应该怎么即时释放掉GDI+的资源？

用GDI+也能写出这东西 厉害

LZV5，代码有注释可读性会更高，特别是对于我这种菜鸟来说

VOID Example_FromHDC(HDC hdc) { Graphics* pGraphics = Graphics::FromHDC(hdc); Pen pen(Color(255, 255, 0, 0)); pGraphics->DrawRectangle(&pen, 10, 10, 200, 100); delete pGraphics; }

LZ天才啊，居然运用graphic的叠加模式做这样的效果。给大伙解释下g2->SetInterpolationMode(InterpolationModeHighQualityBicubic);的作用吧

错了，是g1->SetCompositingQuality (CompositingQualityAssumeLinear);这句？

学习了，感谢分享

整理下8l的代码 乱的总不愿意看

哈哈　好贴　最近就在研究这个

[苒止]

这个字体效果不错啊

[JYSML]

DrawFrame()函数在哪里调用，我在OnPaint（）中调用，每重画一次，非重画区透明度降低，最总是全不透明
