添加剂勾兑[关于"问题;和"色调更换" [英] Question about "Additive blending" and "Hue replacement"
问题描述
由于绘图的字体是在CPU方面相当昂贵，
许多开发者使用光栅字体上绘制视频游戏的文字;这就是我确实做了。
Since drawing fonts is quite expensive in terms of CPU, many developers use a rasterized font to draw text on video games; that's what I did too.
使用添加剂调合而成绘制文本时就字型边缘做工精细，
这些很好地合并与背景颜色。
Using additive blending when drawing the text works fine regarding glyph edges, these merge nicely with the background color.
但它带来了另一个问题，
But it brought another issue,
我决定推行颜色参数绘制的字体，而不是生成字形每种颜色的位图，否则内存使用情况可能很快就会成为一个问题;这取决于有多少字形和颜色都需要，而且字体大小和，因为它支持Unicode，可以有成千上万的字形需要根据不同的语言。
I decided to implement a 'color' parameter for drawing the font, instead of producing glyphs bitmaps for each color, otherwise memory usage might be an issue soon; depending how many glyphs and colors are needed but also the font size and since it supports Unicode, there can be thousands of glyphs needed depending the language.
现在，说一个红色背景绿色环保的字体，它会'橙'！
哪个是添加剂调合而成的目的，而是试图绕过这个去多了几分复杂高于预期。显然，当背景是'黑'，但它可能不是最终的颜色不会发生。
Now when I blend, say a 'Green' font on a 'Red' background, it goes 'Orange' ! Which is the purpose of additive blending, but trying to bypass this went a little more complicate than expected. Obviously it doesn't happen when background is 'Black' but it might not be that color in the end.
我怎样才能重新着色我的'白'字体'任何？'色彩，同时仍保留添加剂勾兑了任意颜色
How can I recolor my 'White' font to 'Any' color, while still retaining additive blending over 'Any' color ?
非常感谢：D
