问题描述
如何从TextureRegion或Sprite创建Pixmap?我需要这样做,以便更改某些像素的颜色,然后从Pixmap创建新的Texture(在加载屏幕期间).
How do I create Pixmap from TextureRegion or from Sprite? I need this in order to change color of some pixels and then create new Texture from Pixmap (during loading screen).
推荐答案
Texture texture = textureRegion.getTexture();
if (!texture.getTextureData().isPrepared()) {
texture.getTextureData().prepare();
}
Pixmap pixmap = texture.getTextureData().consumePixmap();
如果只需要该纹理的一部分(该区域),则必须进行一些手动处理:
If you want only a part of that texture (the region), then you'll have to do some manual processing:
for (int x = 0; x < textureRegion.getRegionWidth(); x++) {
for (int y = 0; y < textureRegion.getRegionHeight(); y++) {
int colorInt = pixmap.getPixel(textureRegion.getRegionX() + x, textureRegion.getRegionY() + y);
// you could now draw that color at (x, y) of another pixmap of the size (regionWidth, regionHeight)
}
}
