彩色半调

“彩色半调”滤镜模拟在图层上使用放大的半调网屏的效果。滤镜将图像划分为矩形，并用圆形替换每个矩形。圆形的大小与矩形的亮度成比例。

应用彩色半调滤镜

  1. 在“编辑”工作区中，选择图像、图层或区域。
  2. 从“滤镜”菜单中选择“像素化”>“彩色半调”。
  3. 为半调网点的最大半径输入一个从 4 到 127 像素的值。
  4. 为一个或多个通道输入介于 -360 到 360 之间的网角值（网点与实际水平线的夹角）：

    • 对于灰度图像，在通道 1 中输入值。其他通道文本框中的值不影响该滤镜。

    • 对于彩色图像，使用通道 1、2、3 和 4，这些通道与 CMYK 通道相对应（青色、洋红色、黄色和黑色）。

  5. 单击“默认”可将所有网角恢复为其默认值，然后单击“确定”。

晶格化

“晶格化”滤镜将图层重新绘制为多边形的颜色块。可以设置晶体的晶格大小。

彩块化

“彩块化”滤镜将图层重新绘制为纯色的块。可以使用此滤镜使扫描的图像看起来像手绘图像，或使现实主义图像类似抽象派绘画。

碎片

“碎片”滤镜重新绘制图层，以便看上去存在偏移和模糊。

铜版雕刻

“铜版雕刻”滤镜将图层重新绘制为灰度图像中黑白区域的随机图案，或者彩色图像中完全饱和颜色的随机图案。可以选择点、线或描边图案。

马赛克

“马赛克”滤镜将图层重新绘制为彩色的正方块。可以设置马赛克单元格大小。

点状化

“点状化”滤镜将图层重新绘制为随机放置的点，就像在点画中一样，并且使用工具箱中的背景颜色作为点之间的画布区域。可以设置单元格大小。
