PsdReader Class

This class enables you to read PSD images.

Namespace: Aurigma.GraphicsMill.Codecs
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic 
Public NotInheritable Class PsdReader _
	Inherits FormatReader _
	Implements IMetadataReadSupport
C# 
public sealed class PsdReader : FormatReader, IMetadataReadSupport

Remarks

PSD is the native bitmap file format of the Adobe® Photoshop® graphics editor. This format is standard de facto for designers all over the world. This format is rather complex and stores a lot of data (image layers, text, effects, etc). It is rather complex task to parse it and merge all the layers as they are displayed in the Photoshop. The good news is that PSD file always stores image where all the layers are merged in correct way. Graphics Mill for .NET can load this merged layer, so you can work with PSD files as well as with other image formats.

Examples

The code sample below extracts EXIF and IPTC metadata from the PSD file and displays it. It also demonstrates the usage of the PsdReader class.

Visual Basic 
Dim bitmap As New Aurigma.GraphicsMill.Bitmap

Dim reader As New Aurigma.GraphicsMill.Codecs.PsdReader("c:\Mountain.psd")

'Read metadata
Dim exif As Aurigma.GraphicsMill.Codecs.ExifDictionary = reader.Exif
Dim iptc As Aurigma.GraphicsMill.Codecs.IptcDictionary = reader.Iptc

'Read bitmap
Dim frame As Aurigma.GraphicsMill.Codecs.Frame = reader.LoadFrame(0)
frame.GetBitmap(bitmap)

frame.Dispose()

reader.Dispose()

'Show EXIF tags
If Not exif Is Nothing Then
    Console.WriteLine("EXIF")
    Console.WriteLine("---------------")
    For Each key As Long In exif.Keys
        Console.WriteLine("{0}: {1}", exif.GetKeyDescription(key), exif.GetItemString(key))
    Next
End If

'Show IPTC tags
If Not iptc Is Nothing Then
    Console.WriteLine("IPTC")
    Console.WriteLine("---------------")
    For Each key As Long In iptc.Keys
        Console.WriteLine("{0}: {1}", iptc.GetKeyDescription(key), iptc.GetItemString(key))
    Next
End If
C# 
Aurigma.GraphicsMill.Bitmap bitmap = new Aurigma.GraphicsMill.Bitmap();

Aurigma.GraphicsMill.Codecs.PsdReader reader = 
    new Aurigma.GraphicsMill.Codecs.PsdReader(@"c:\Mountain.psd");

//Read metadata
Aurigma.GraphicsMill.Codecs.ExifDictionary exif = reader.Exif;
Aurigma.GraphicsMill.Codecs.IptcDictionary iptc = reader.Iptc;

//Read bitmap
Aurigma.GraphicsMill.Codecs.IFrame frame = reader.LoadFrame(0);
frame.GetBitmap(bitmap);

frame.Dispose();

reader.Dispose();

//Show EXIF tags
if (exif != null)
{
    Console.WriteLine("EXIF");
    Console.WriteLine("---------------");
    foreach (long key in exif.Keys)
    {
        Console.WriteLine("{0}: {1}", exif.GetKeyDescription(key), exif.GetItemString(key));
    }
}

//Show IPTC tags
if (iptc != null)
{
    Console.WriteLine("IPTC");
    Console.WriteLine("---------------");
    foreach (long key in iptc.Keys)
    {
        Console.WriteLine("{0}: {1}", iptc.GetKeyDescription(key), iptc.GetItemString(key));
    }
}
