Examples

This example demonstrates the loading of an existing Image file into an instance of Aspose.PSD.Image using file path specified

[C#]

//Create Image instance and initialize it with an existing image file from disk location
string path = "C:\\temp\\image.psd";
using (Aspose.PSD.Image image = Aspose.PSD.Image.Load(path))
{
    //do some image processing
}

The following example demonstrates that the Text Alignment through ITextPortion for right-to-left languages works correctly.

[C#]

string sourceFilePath = "bidi.psd";
string exportFilePath = "bidiOutput.psd";

using (PsdImage image = (PsdImage)Image.Load(sourceFilePath))
{
    TextLayer layer = (TextLayer)image.Layers[2];
    ITextPortion[] portions = layer.TextData.Items;

    portions[0].Paragraph.Justification = JustificationMode.Center;
    layer.TextData.UpdateLayerData();

    image.Save(exportFilePath);
}

The following example demonstrates that reading and saving the Grayscale 16 bit PSD files to 16bit per channel RGB works correctly and without an exception.

[C#]

string sourceFilePath = "grayscale5x5.psd";
string exportFilePath = "rgb16bit5x5.psd";
PsdOptions psdOptions = new PsdOptions()
{
    ColorMode = ColorModes.Rgb,
    ChannelBitsCount = 16,
    ChannelsCount = 4
};

using (PsdImage image = (PsdImage)Image.Load(sourceFilePath))
{
    RasterCachedImage raster = image.Layers[0];
    Aspose.PSD.Graphics graphics = new Graphics(raster);
    int width = raster.Width;
    int height = raster.Height;
    Rectangle rect = new Rectangle(width / 3, height / 3, width - (2 * (width / 3)) - 1, height - (2 * (height / 3)) - 1);
    graphics.DrawRectangle(new Aspose.PSD.Pen(Color.DarkGray, 1), rect);
    image.Save(exportFilePath, psdOptions);
}

string pngExportPath = Path.ChangeExtension(exportFilePath, "png");
using (PsdImage image = (PsdImage)Image.Load(exportFilePath))
{
    // Here should be no exception.
    image.Save(pngExportPath, new PngOptions() { ColorType = PngColorType.GrayscaleWithAlpha });
}

The following example demonstrates that reading and saving the Grayscale 16 bit PSD files to 8 bit per channel Grayscale works correctly and without an exception.

[C#]

string sourceFilePath = "grayscale16bit.psd";
string exportFilePath = "grayscale16bit_Grayscale8_2_RLE.psd";
PsdOptions psdOptions = new PsdOptions()
{
    ColorMode = ColorModes.Grayscale,
    ChannelBitsCount = 8,
    ChannelsCount = 2
};

using (PsdImage image = (PsdImage)Image.Load(sourceFilePath))
{
    RasterCachedImage raster = image.Layers[0];
    Aspose.PSD.Graphics graphics = new Graphics(raster);
    int width = raster.Width;
    int height = raster.Height;
    Rectangle rect = new Rectangle(width / 3, height / 3, width - (2 * (width / 3)) - 1, height - (2 * (height / 3)) - 1);
    graphics.DrawRectangle(new Aspose.PSD.Pen(Color.DarkGray, 1), rect);
    image.Save(exportFilePath, psdOptions);
}

string pngExportPath = Path.ChangeExtension(exportFilePath, "png");
using (PsdImage image = (PsdImage)Image.Load(exportFilePath))
{
    // Here should be no exception.
    image.Save(pngExportPath, new PngOptions() { ColorType = PngColorType.GrayscaleWithAlpha });
}

The following example demonstrates that the document conversion progress works correctly and without an exception.

[C#]

string sourceFilePath = "Apple.psd";
Stream outputStream = new MemoryStream();

Aspose.PSD.ProgressEventHandler localProgressEventHandler = delegate(ProgressEventHandlerInfo progressInfo)
{
    string message = string.Format(
        "{0} {1}: {2} out of {3}",
        progressInfo.Description,
        progressInfo.EventType,
        progressInfo.Value,
        progressInfo.MaxValue);
    Console.WriteLine(message);
};

Console.WriteLine("---------- Loading Apple.psd ----------");
var loadOptions = new PsdLoadOptions() { ProgressEventHandler = localProgressEventHandler };
using (PsdImage image = (PsdImage)Image.Load(sourceFilePath, loadOptions))
{
    Console.WriteLine("---------- Saving Apple.psd to PNG format ----------");
    image.Save(
        outputStream,
        new PngOptions()
            {
                ColorType = PngColorType.Truecolor,
                ProgressEventHandler = localProgressEventHandler
            });

    Console.WriteLine("---------- Saving Apple.psd to PSD format ----------");
    image.Save(
        outputStream,
        new PsdOptions()
            {
                ColorMode = ColorModes.Rgb,
                ChannelsCount = 4,
                ProgressEventHandler = localProgressEventHandler
            });
}

Examples

This example demonstrates the use of System.IO.Stream objects to load an existing Image file

//Create an instance of FileStream
using(System.IO.FileStream stream = new System.IO.FileStream(@"C:\temp\sample.psd",System.IO.FileMode.Open))

    using (Aspose.PSD.Image image = Aspose.PSD.Image.Load(stream))
    {
        //do some image processing.
