此页面包含Aspose.PSD for .NET 22.9的发行说明。
- 此版本在16位图像导出时存在回归问题,因此我们建议在使用此版本的此功能时要谨慎。如果16位图像处理是您的主要功能,请不要升级至 Aspose.PSD 22.9。
- 对于几个版本的 Photoshop,用户可能会遇到一个带有读取层错误的窗口,这不会影响与 PSD 文件的工作。
我们正在努力解决这些问题。
关键 | 摘要 | 类别 |
---|---|---|
PSDNET-1237 | 创建内部 LayerStyleFX 模型,用于包含效果和相关数据,以在效果资源 Lfx2、lmfx 和 mlst 中使用单个模型 | 增强功能 |
PSDNET-1227 | 添加读取和写入 ‘Lefx’ 结构的功能,其中包含时间线模型中图层状态的效果信息 | 特性 |
PSDNET-1230 | 将时间线图层状态应用于 PsdImage 中的图层 | 特性 |

使用示例:
PSDNET-1072.在导出至 8 位时,将 PSD 文件(RGB/16 位)上的不正确透明度保存
string inputPsdFile = "8bitWithTransparency.psd";
string outputPsdFile = "16bitWithTransparency.psd";
string outputImageFile = "OutputWithTransparency.png";
using (var img = Image.Load(inputPsdFile))
{
// 16 位保存选项
PsdOptions p16 = new PsdOptions() { ChannelBitsCount = 16, ColorMode = ColorModes.Rgb };
img.Save(outputPsdFile, p16);
}
using (var img = Image.Load(outputPsdFile))
{
// 使用 16 位颜色保存图片
img.Save(outputImageFile, new PngOptions() { ColorType = Aspose.PSD.FileFormats.Png.PngColorType.TruecolorWithAlpha });
}
PSDNET-1140.在打开 PSB 文档时加载全局图层资源步骤中出现异常
string sourcePsdFile = "input.psb";
string outputImageFile = "output.png";
using (var image = (PsdImage)Image.Load(sourcePsdFile))
{
// 这里不应该出现异常。
image.Save(outputImageFile, new PngOptions() { ColorType = PngColorType.GrayscaleWithAlpha });
}
PSDNET-1227.添加读取和写入 ‘Lefx’ 结构的功能,其中包含时间线模型中图层状态的效果信息
string sourceFile = "4_animated.psd";
string outputFile = "output.psd";
using (var psdImage = (PsdImage)Image.Load(sourceFile))
{
TimeLine timeLine = TimeLine.InitializeFrom(psdImage);
int[] layerIds = timeLine.LayerIds;
var layerStateEffects11 = timeLine.Frames[1].LayerStates[layerIds[1]].StateEffects;
layerStateEffects11.AddDropShadow();
layerStateEffects11.AddGradientOverlay();
var layerStateEffects21 = timeLine.Frames[2].LayerStates[layerIds[1]].StateEffects;
layerStateEffects21.AddStroke(FillType.Color);
layerStateEffects21.IsVisible = false;
timeLine.ApplyTo(psdImage);
psdImage.Save(outputFile);
}
PSDNET-1230.将时间线图层状态应用于 PsdImage 中的图层
string sourceFile = "3_animated.psd";
string outputPsd = "output.psd";
string outputPng = "output.png";
using (var psdImage = (PsdImage)Image.Load(sourceFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
TimeLine timeLine = TimeLine.InitializeFrom(psdImage);
var layerIds = timeLine.LayerIds;
var layerState11 = timeLine.Frames[1].LayerStates[layerIds[1]];
timeLine.Frames[1].LayerStates[layerIds[1]].StateEffects.AddPatternOverlay();
layerState11.BlendMode = BlendMode.Multiply;
// 将活动帧从 0 更改为 1 以启用将 LayerState 应用于 Layer
timeLine.ActiveFrame = 1;
// 将更改应用于 PsdImage
timeLine.ApplyTo(psdImage);
psdImage.Save(outputPsd);
psdImage.Save(outputPng, new PngOptions());
}
PSDNET-1266.处理特定文件时存在内存泄漏
string[] filesToLoad = new string[] { "testPsd0.psd", "testPsd1.psd", "testPsd2.psd" };
int inputNumber = GC.MaxGeneration;
#if NETCOREAPP
GCSettings.LargeObjectHeapCompactionMode = GCLargeObjectHeapCompactionMode.CompactOnce;
#endif
GC.Collect(inputNumber, GCCollectionMode.Forced);
GC.WaitForFullGCComplete();
double memCount = (double)Process.GetCurrentProcess().PrivateMemorySize64 / 1024 / 1024;
Console.WriteLine("测试前使用的总字节: {0:N2} MiB", memCount);
double max = memCount;
for (int i = 0; i < 50; i++)
{
int fileIndex = i % inputNumber;
string sourceFile = Path.Combine(baseFolder, filesToLoad[fileIndex]);
// 检查打开和保存
using (MemoryStream outputStream = new MemoryStream())
{
using (PsdImage psd = (PsdImage)Image.Load(sourceFile, new PsdLoadOptions { LoadEffectsResource = true }))
{
psd.Save(outputStream, new JpegOptions() { Quality = 100 });
}
}
#if NETCOREAPP
GCSettings.LargeObjectHeapCompactionMode = GCLargeObjectHeapCompactionMode.CompactOnce;
#endif
GC.Collect(inputNumber, GCCollectionMode.Forced);
GC.WaitForFullGCComplete();
memCount = (double)Process.GetCurrentProcess().PrivateMemorySize64 / 1024 / 1024;
max = Math.Max(max, memCount);
}
memCount = (double)Process.GetCurrentProcess().PrivateMemorySize64 / 1024 / 1024;
Console.WriteLine("测试后使用的总字节: {0:N2} MiB", memCount);
Assert.IsTrue(Math.Abs(memCount - max) < 20, "发现基本功能中的内存泄漏!");
