用法示例：

PSDNET-207. 支持颜色平衡调整图层

            var filePath = "ColorBalance.psd";

            var outputPath = "ColorBalance_out.psd";

            using (var im = (PsdImage)Image.Load(filePath))

            {

                foreach (var layer in im.Layers)

                {

                    var cbLayer = layer as ColorBalanceAdjustmentLayer;

                    if (cbLayer != null)

                    {

                        cbLayer.ShadowsCyanRedBalance = 30;

                        cbLayer.ShadowsMagentaGreenBalance = -15;

                        cbLayer.ShadowsYellowBlueBalance = 40;

                        cbLayer.MidtonesCyanRedBalance = -90;

                        cbLayer.MidtonesMagentaGreenBalance = -25;

                        cbLayer.HighlightsMagentaGreenBalance = 67;

                        cbLayer.HighlightsYellowBlueBalance = -95;

                        cbLayer.PreserveLuminosity = true;

                    }

            var layer = layers[index];

            if (!(layer is TextLayer)) continue;

            var textLayer = (TextLayer)layer;

            textLayer.UpdateText("/");

        }

        var imageOptions = new PsdOptions(psdImage);

        var fileName = Path.GetFileName(filePath);

            using (var image = Image.Load(filePath))

            {

                int layerIndex = 22;

                // 旧 API（使用第一个段落字体）

                PsdImage psdImage = image as PsdImage;

                double[] matrix = ((TextLayer)psdImage.Layers[layerIndex]).TransformMatrix;

                double baseFontSize = ((TextLayer)psdImage.Layers[layerIndex]).Font.Size;

                double fontSize = matrix[0] * baseFontSize;

                // 检查基本字体大小

                if (Math.Abs(100.0 - baseFontSize) > tolerance)

                {

                    throw new Exception("字体大小读取错误");

                }

                // 检查实际字体大小

                if (Math.Abs(88.425 - fontSize) > tolerance)

                {

                    throw new Exception("TransformMatrix 读取错误");

                }

                // 新 API（一个文本图层可能包含任意数量的字体大小）

                ITextPortion[] portions = ((TextLayer)psdImage.Layers[layerIndex]).TextData.Items;

                ITextStyle style = portions[0].Style;

                double fontSizeOfPortion = matrix[0] * style.FontSize;

                // 检查基本部分字体大小

                if (Math.Abs(100.0 - style.FontSize) > tolerance)

                {

                    throw new Exception("字体大小读取错误");

                }

                // 检查实际部分字体大小

                if (Math.Abs(88.425 - fontSizeOfPortion) > tolerance)

                {

                }

            }

PSDNET-179. 获取图层 DropShadowEffect 问题

       // 当 DropShadowEffect.UseGlobalLight 属性为 'true' 时，DropShadowEffect 对象使用 PsdImage.GlobalAngle 属性的角度值。

		using (PsdImage image = (PsdImage)Image.Load("4.psd"))

		{

    		image.GlobalAngle = 30;

    		image.Save("output.psd");
