Layer.Layer

Layer()

Initializes a new instance of the Layer class. Constructor for lazy initialization.

public Layer()

Examples

The following example demonstrates how you can draw on a newly created layer if the simple constructor version is used in Aspose.PSD

[C#]

string outputFilePath = "output.psd";

int width = 100;
int height = 100;
using (var image = new PsdImage(width, height))
{
    var layer = new Layer();
    layer.Bottom = height;
    layer.Right = width;
    image.AddLayer(layer);

    Graphics graphic = new Graphics(layer);
    graphic.Clear(Color.Yellow);

    // draw a rectangle with Pen tool
    graphic.DrawRectangle(new Pen(Color.Red), new Rectangle(30, 10, 40, 80));

    // draw another rectangle with Solid Brush in Blue color
    graphic.DrawRectangle(new Pen(new SolidBrush(Color.Blue)), new Rectangle(10, 30, 80, 40));

    image.Save(outputFilePath);
}

Layer(RasterImage, bool)

Initializes a new instance of the Layer class.

public Layer(RasterImage image, bool disposeImage = false)
ParameterTypeDescription
imageRasterImageThe image.
disposeImageBooleanif set to true [dispose image].

Examples

The following code demonstrates ability to load JPEG/PNG/etc image files to PsdImage without direct loading.

[C#]

string filePath = "PsdExample.psd";
string outputFilePath = "PsdResult.psd";
using (var image = new PsdImage(200, 200))
{
    using (var im = Image.Load(filePath))
    {
        Layer layer = null;
        try
        {
            layer = new Layer((RasterImage)im);
            image.AddLayer(layer);
        }
        catch (Exception)
        {
            if (layer != null)
            {
                layer.Dispose();
            }

            throw;
        }
    }

    image.Save(outputFilePath);
}

Layer(Stream)

Initializes a new instance of the Layer class.

public Layer(Stream stream)
ParameterTypeDescription
streamStreamThe image stream

Examples

The following example demonstrates how you can add Bmp, Jpeg, Jpeg2000, Png, Psd, Tiff, Gif images as layers to PsdImage

[C#]

string outputFilePath = "PsdResult.psd";

var filesList = new string[]
{
    "PsdExample.psd",
    "BmpExample.bmp",
    "GifExample.gif",
    "Jpeg2000Example.jpf",
    "JpegExample.jpg",
    "PngExample.png",
    "TiffExample.tif",
};

using (var image = new PsdImage(200, 200))
{
    foreach (var fileName in filesList)
    {
        string filePath = fileName;
        using (var stream = new FileStream(filePath, FileMode.Open))
        {
            Layer layer = null;
            try
            {
                layer = new Layer(stream);
                image.AddLayer(layer);
            }
            catch (Exception e)
            {
                if (layer != null)
                {
                    layer.Dispose();
                }

                throw e;
            }
        }
    }

    image.Save(outputFilePath);
}

ParameterTypeDescription
boundsRectangleThe layer bounds.
redBytesByte[]The red bytes.
greenBytesByte[]The green bytes.
