提高DirectWrite中渲染文本的性能。 [英] Improving performance of rendering text in DirectWrite.

问题描述

您好，

我在DirectWrite中渲染文本时遇到问题。我知道，每帧使用drawtext和drawtextlayout确实会减慢游戏速度，但我希望创建文本的几何体，我可以存储和刷新文本，当我的文本发生变化时。以前我使用FW1FontWrapper
librabry，但它不支持Windows Phone，所以我必须更改它。我尝试将rendertarget保存到位图然后绘制它，但它是如此缓慢，对于~400行文本，fps反复下降。所以也许有人帮助我，我的文字怎么办？

Hello,

I have a problem with rendering text in DirectWrite. I know, that using drawtext and drawtextlayout per frame really slows the game, but I want to create geometry of the text, that I can store and refresh, when my text change. Previously I use a FW1FontWrapper librabry, but it doesn't support Windows Phone, so I must change it. I try to save rendertarget to bitmap and later draw it, but it is so slow and for ~400 line of text, fps counter down quicly. So maybe anybody help me, what can I do with my text?
