PSB 到 PNG 的转换

将 Photoshop® 大型文档“PSB”（Photoshop Big）文件格式转换为“PNG”（便携式网络图形）光栅图像格式。

string sourcePsdFile = "input.psb";
string outputImageFile = "output.png";

using (var image = (PsdImage)Image.Load(sourcePsdFile))
{
    // Here should be no exception.
    image.Save(outputImageFile, new PngOptions() { ColorType = PngColorType.GrayscaleWithAlpha });
}

将时间轴层状态应用到 PSD 层

使用 C# 代码将图层状态应用于“PSD”图像时间轴内的图层。

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;

    // Change active frame from 0 to 1 to activate applying of LayerState to Layer
    timeLine.ActiveFrame = 1;

    // Apply changes to PsdImage
    timeLine.ApplyTo(psdImage);

    psdImage.Save(outputPsd);
    psdImage.Save(outputPng, new PngOptions());
}

没有任何内存泄漏的图形处理

处理图形文件时避免内存泄漏，例如PSD。

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("Total used bytes before test: {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]);

    // CheckOpenSaving
    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("Total used bytes after test: {0:N2} MiB", memCount);
Assert.IsTrue(Math.Abs(memCount - max) < 20, "Memory leak in base functionality found!");
