SoCoResource的支持

 SoCoResource 包含有关颜色填充图层的信息。本文演示了Aspose.PSD for Java 如何支持PSD文件中的SoCoResource。

• 使用Image类的工厂方法Load将PSD文件加载为图像
• 从图像图层中获取SoCoResource
• 设置所需属性
• 保存结果

 以下代码片段展示了Aspose.PSD for Java如何支持SoCoResource。

                            socoResource.setColor(Color.getRed());
                            break;
