公共API更改
已添加的API:
- T:Aspose.PSD.FileFormats.Psd.Layers.SectionDividerLayer
- M:Aspose.PSD.FileFormats.Psd.Layers.SectionDividerLayer.GetRelatedLayerGroup
- P:Aspose.PSD.FileFormats.Psd.Layers.SectionDividerLayer.IsVisibleInGroup
已移除的API:
- 无
使用示例:
PSDNET-694. 在读取PattResource时，宽度和高度被交换
string sourceFile = "Untitled-1.psd";
string outputFile = "output.png";
using (var image = (PsdImage)Image.Load(sourceFile))
{
var fillLayer = (FillLayer)image.Layers[1];
fillLayer.Update(); // 调用模式渲染
image.Save(outputFile, new PngOptions());
}
PSDNET-789. 多个图层效果的混合不正确
string srcFile = "source_789.psd";
string outputSmartObjectPath = "output789.png";
string outputFile = "output789.psd";
using (PsdImage image = (PsdImage)Image.Load(srcFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
var length = image.Layers.Length;
for (int i = 0; i < length; i++)
{
var smart = image.Layers[i] as SmartObjectLayer;
if (smart != null && smart.Name == "__D__")
{
using (var stream = new MemoryStream(smart.Contents))
{
stream.Position = 0;
using (var imageInSmart = (PsdImage)Image.Load(stream))
{
for (int j = 0; j < imageInSmart.Layers.Length; j++)
{
// 寻找文本图层
var textLayer = imageInSmart.Layers[j] as TextLayer;
if (textLayer != null)
{
var textData = textLayer.TextData;
textData.Items[0].Text = "最佳";
textData.Items[0].Style.FontSize = 170;
}
}
smart.ReplaceContents(imageInSmart);
}
}
break;
}
}
// 以这种方式保存已更改的PSD文件
image.Save(outputSmartObjectPath, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
image.Save(outputFile);
}
PSDNET-805. 存在多个图层效果时，混合顺序和逻辑不正确
string sourceFile = "1_200x200.psd";
string contentFile = "Numbers1Best.png";
string outputFilePng = "output.png";
string outputFilePsd = "output.psd";
using (PsdImage image = (PsdImage)Image.Load(sourceFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
var length = image.Layers.Length;
for (int i = 0; i < length; i++)
{
var smart = image.Layers[i] as SmartObjectLayer;
if (smart != null && smart.Name == "__D__")
{
smart.ReplaceContents(contentFile);
break;
}
}
// 以这种方式保存已更改的PSD文件
image.Save(outputFilePng, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
image.Save(outputFilePsd);
}
PSDNET-823. 添加SectionDividerLayer以改善图层组的体验
// 以下代码演示SectionDividerLayer图层以及如何获取相关的LayerGroup。
// 图层层次结构
// [0]: '</图层组>' Group 1的SectionDividerLayer
// [1]: '图层 1' 普通图层
// [2]: '</图层组>' Group 2的SectionDividerLayer
// [3]: '</图层组>' Group 3的SectionDividerLayer
// [4]: 'Group 3' GroupLayer
// [5]: 'Group 2' GroupLayer
// [6]: 'Group 1' GroupLayer
void AssertAreEqual(object expected, object actual, string message = null)
{
if (!object.Equals(expected, actual))
{
throw new FormatException(message ?? "对象不相等。");
}
}
using (var image = new PsdImage(100, 100))
{
// 创建图层层次结构
// 添加图层组 'Group 1'
LayerGroup group1 = image.AddLayerGroup("Group 1", 0, true);
// 添加普通图层
Layer layer1 = new Layer();
layer1.DisplayName = "图层 1";
group1.AddLayer(layer1);
// 添加图层组 'Group 2'
LayerGroup group2 = group1.AddLayerGroup("Group 2", 1);
// 添加图层组 'Group 3'
LayerGroup group3 = group2.AddLayerGroup("Group 3", 0);
// 获取SectionDividerLayer的实例
SectionDividerLayer divider1 = (SectionDividerLayer)image.Layers[0];
SectionDividerLayer divider2 = (SectionDividerLayer)image.Layers[2];
SectionDividerLayer divider3 = (SectionDividerLayer)image.Layers[3];
// 使用SectionDividerLayer.GetRelatedLayerGroup()方法，获取相关的LayerGroup实例。
AssertAreEqual(group1.DisplayName, divider1.GetRelatedLayerGroup().DisplayName); // 同一个LayerGroup
AssertAreEqual(group2.DisplayName, divider2.GetRelatedLayerGroup().DisplayName); // 同一个LayerGroup
AssertAreEqual(group3.DisplayName, divider3.GetRelatedLayerGroup().DisplayName); // 同一个LayerGroup
LayerGroup folder1 = divider1.GetRelatedLayerGroup();
AssertAreEqual(5, folder1.Layers.Length); // 'Group 1' 包含5个图层
}
PSDNET-842. 描边效果属性未保存到PSD文件
void AssertAreEqual(object expected, object actual, string message = null)
{
if (!object.Equals(expected, actual))
{
throw new FormatException(message ?? "对象不相等。");
}
}
string srcFile = "badStrokeEffect.psd";
string output = "output.psd";
using (var image = (PsdImage)Image.Load(srcFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
var layer1 = new Layer();
image.AddLayer(layer1);
layer1.BlendingOptions.AddStroke(FillType.Color); // 不会抛出ArgumentNullException
StrokeEffect strokeEffect = image.Layers[1].BlendingOptions.AddStroke(FillType.Color);
strokeEffect.Size = 10;
strokeEffect.Position = StrokePosition.Outside;
strokeEffect.Overprint = true;
image.Save(output);
}
// 检查保存的值
using (var image = (PsdImage)Image.Load(output, new PsdLoadOptions() { LoadEffectsResource = true }))
{
StrokeEffect strokeEffect = (StrokeEffect)image.Layers[1].BlendingOptions.Effects[0];
AssertAreEqual(10, strokeEffect.Size);
AssertAreEqual(StrokePosition.Outside, strokeEffect.Position);
AssertAreEqual(true, strokeEffect.Overprint);
}
