Java:如何以编程方式为该PNG着色? [英] Java : How to tint this PNG programmatically?

问题描述

在一个国际象棋小程序的框架内，我有几套这样的灰度/黑色和黑色.白色(不确定):

Within the frame of a chess applet, I have a few sets of such greyscale/black & white (not sure) :

是否可以通过Java代码为PNG图片赋予颜色色彩?试图用谷歌搜索此事，但没有找到与我要找的东西真正匹配的东西.

Is there any way to give a color tint to a PNG picture via Java Code ? Tried to google the matter and didn't find anything really matching what I'm looking for.

例如，对于以下作品，我想为White播放器赋予白色/黄色调，为Black播放器赋予黑色的风味.动态设置颜色的想法是在运行时调整主题.

For the following piece for example, I'd like to give it white/yellow tint for the White player, and a flavour of black for the Black player. The idea of setting the color dynamically is to tweak themes at runtime.

推荐答案

为您的程序提供半透明图像(PNG)更为简单，这些图像可以是所需颜色的纯色(纯色或渐变色)，一定百分比的透明度(您可以在1分钟内在photoshop/illustrator中完成此操作).

It would be a lot simpler to give your program translucent images (PNG) which are plain coloured (plain or gradient) in the colours you want, and have a certain % of transparency (you can do that in photoshop/illustrator in 1min).

然后以编程方式将着色图像(保持透明度)与下面的其他图像合并.

Then programmatically merge the tint image (preserving transparency) with the other image underneath.
