PsdLoadOptions.ReadOnlyType

PsdLoadOptions.ReadOnlyType property

Gets or sets the read-only mode used when loading a PSD image.

public ReadOnlyMode ReadOnlyType { get; set; }

Property Value

One of the ReadOnlyMode values:

  • !:ReadOnlyMode.None – No restrictions. Image content can be modified.
  • !:ReadOnlyMode.Default – The image is fully read-only.
  • !:ReadOnlyMode.MetadataEdit – Only metadata can be edited (such as ImageResources), while image pixel content remains read-only.

Examples

Demonstrates editing and saving PSD metadata using ReadOnlyMode.MetadataEdit.

[C#]

string sourceFile = "psdnet2382.psd";
string outputFile = "output.psd";

string testMetadata = "Updated metadata text";

using (PsdImage psdImage = (PsdImage)Aspose.PSD.Image.Load(sourceFile,
    new PsdLoadOptions() { ReadOnlyType = ReadOnlyMode.MetadataEdit })) // Sets the of ReadOnlyMode to true
{
    AssertAreNotEqual(testMetadata, psdImage.XmpData.Meta.AdobeXmpToolkit);

    // Change metadata in ReadOnlyMode
    psdImage.XmpData.Meta.AdobeXmpToolkit = testMetadata;

    // Save changed metadata in ReadOnlyMode
    psdImage.Save(outputFile);
}

using (PsdImage psdImage = (PsdImage)Aspose.PSD.Image.Load(outputFile)) // Sets the of ReadOnlyMode to true
{
    AssertAreEqual(testMetadata, psdImage.XmpData.Meta.AdobeXmpToolkit);
}

void AssertAreEqual(object expected, object actual)
{
    if (!object.Equals(expected, actual))
    {
        throw new Exception("Objects should be equal, but they don't.");
    }
}

void AssertAreNotEqual(object obj1, object obj2)
{
    if (object.Equals(obj1, obj2))
    {
        throw new Exception("Objects should not be equal, but they are equal.");
    }
}
