Usage examples:

PSDNET-913. PSD information lost on just opening and saving

string src = "Original file.psd";
string outputPsd = "out_Original file.psd";
string outputPng = "out_Original file.png";

using (var psdImage = (PsdImage)Image.Load(src))
{
    psdImage.Save(outputPsd);
    psdImage.Save(outputPng, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
}

PSDNET-1352. Image loading failed

string srcFile1 = "test_text.psd";
string srcFile2 = "test_smart_object.psd";

using (PsdImage psdImage = (PsdImage)Aspose.PSD.Image.Load(srcFile1))
{
}

using (PsdImage psdImage = (PsdImage)Aspose.PSD.Image.Load(srcFile2))
{
}

PSDNET-1553. Image loading failed: Unable to cast object of type UnknownStructure to type DescriptorStructure

using (PsdImage newPsd = (PsdImage)new PsdImage(10, 10))
{
    newPsd.AddLayer(FillLayer.CreateInstance(FillType.Gradient));

    using (var memStream = new MemoryStream(DescriptorStructure.StructureKey + 1000))
    {
        newPsd.Save(memStream);

        memStream.Seek(DescriptorStructure.StructureKey, System.IO.SeekOrigin.Current);
        memStream.Write(new byte[1]);
        memStream.Position = 0;

        using (PsdImage psdImage = (PsdImage)Image.Load(memStream))
        {
            // Should load correctly
        }
    }
}

PSDNET-1631. File changed in the 3rd party library corrupts PSD file but it can be opened in the Photoshop

string sourceFile = "output.psd";
string outputFile = "export.png";

using (PsdImage img = (PsdImage)Image.Load(sourceFile, new PsdLoadOptions() { LoadEffectsResource = true }))
{
    img.Save(outputFile, new PngOptions() { CompressionLevel = 9, ColorType = PngColorType.TruecolorWithAlpha });
}

PSDNET-1566. Add new type of warp (Flag)

string sourceFile = "flag_warp.psd";
string outputFile = "flag_export.png";

using (var psdImage = (PsdImage)Image.Load(sourceFile, new PsdLoadOptions() { AllowWarpRepaint = true, LoadEffectsResource = true }))
{
    psdImage.Save(outputFile, new PngOptions
    {
        ColorType = PngColorType.TruecolorWithAlpha
    });
}

PSDNET-1621. Add new types of warp: arc up, arc down, sphere

string sourceFileArcUpper = "arc_upper_warp.psd";
string sourceFileArcLower = "arc_lower_warp.psd";
string sourceFileBulge =  "bulge_warp.psd";

string outputFileArcUpper ="ArcUpper_export.png";
string outputFileArcLower = "ArcLower_export.png";
string outputFileBulge = "Bulge_export.png";

using (var psdImage = (PsdImage)Image.Load(sourceFileArcUpper, new PsdLoadOptions() { AllowWarpRepaint = true, LoadEffectsResource = true }))
{
    psdImage.Save(outputFileArcUpper, new PngOptions {ColorType = PngColorType.TruecolorWithAlpha});
}

using (var psdImage = (PsdImage)Image.Load(sourceFileArcLower, new PsdLoadOptions() { AllowWarpRepaint = true, LoadEffectsResource = true }))
{
    psdImage.Save(outputFileArcLower, new PngOptions { ColorType = PngColorType.TruecolorWithAlpha });
}

using (var psdImage = (PsdImage)Image.Load(sourceFileBulge, new PsdLoadOptions() { AllowWarpRepaint = true, LoadEffectsResource = true }))
{
    psdImage.Save(outputFileBulge, new PngOptions { ColorType = PngColorType.TruecolorWithAlpha });
}

PSDNET-1682. Implement new method PsdImage.AddPosterizeAdjustmentLayer for adding new Posterize layer

string srcFile = "zendeya.psd";
string outFile = "zendeya.psd.out.psd";

using (PsdImage psdImage = (PsdImage)Image.Load(srcFile))
{
    psdImage.AddPosterizeAdjustmentLayer();
    psdImage.Save(outFile);
}

// Check saved changes
using (PsdImage image = (PsdImage)Image.Load(
    outFile,
    new PsdLoadOptions { LoadEffectsResource = true }))
{
    AssertAreEqual(2, image.Layers.Length);

    PosterizeLayer posterizeLayer = (PosterizeLayer)image.Layers[1];

    AssertAreEqual(true, posterizeLayer is PosterizeLayer);
}

void AssertAreEqual(object expected, object actual, string message = null)
{
    if (!object.Equals(expected, actual))
    {
        throw new Exception(message ?? "Objects are not equal.");
    }
}
