用法示例:

PSDPYTHON-69. 实现支持渐变映射图层

        sourceFile = "gradient_map_src.psd"
        outputFile = "gradient_map_src_output.psd"
      
        def AssertAreEqual(expected, actual, message=None):
            if expected != actual:
                raise Exception(message or "对象不相等。")

        with PsdImage.load(sourceFile) as image:
            im = cast(PsdImage, image)
            layer = im.add_gradient_map_adjustment_layer()
            layer.gradient_settings.reverse = True

            im.save(outputFile)

        with PsdImage.load(outputFile) as image:
            im = cast(PsdImage, image)
            gradient_map_layer = cast(GradientMapLayer, im.layers[1])
            gradient_settings = cast(GradientFillSettings, gradient_map_layer.gradient_settings)

            AssertAreEqual(0.0, gradient_settings.angle)
            AssertAreEqual(4096, gradient_settings.interpolation)
            AssertAreEqual(True, gradient_settings.reverse)
            AssertAreEqual(False, gradient_settings.align_with_layer)
            AssertAreEqual(False, gradient_settings.dither)
            AssertAreEqual(GradientType.LINEAR, gradient_settings.gradient_type)
            AssertAreEqual(100, gradient_settings.scale)
            AssertAreEqual(0.0, gradient_settings.horizontal_offset)
            AssertAreEqual(0.0, gradient_settings.vertical_offset)
            AssertAreEqual("Custom", gradient_settings.gradient_name)

PSDPYTHON-71. 实现膨胀、挤压和扭曲类型的变形

            with PsdImage.load(sourceFile, loadOpt) as psdImage:
                psdImage.save(outputFile, pngOpt)

PSDPYTHON-72. Rgb 和 Lab 模式在包含艺术板图层文件中不能包含少于 3 个通道和多于 4 个通道

        sourceFile = "Rgb5Channels.psb"
        outputFile = "Rgb5Channels_output.psd"

        with PsdImage.load(sourceFile) as image:
            image.save(outputFile)

PSDPYTHON-79. 在处理特定文件的处理区域顶部必须是正数 (参数 ‘areaToProcess’)

PSDPYTHON-74. 保存后，画布图像的展开部分被裁剪。数据丢失，但预览看起来正确

        sourceFile = "bigfile.psd"
        outputFile = "bigfile_output.psd"
        outputPicture = "bigfile.png"
