FillLayer.Update

FillLayer.Update method

Updates the pixel data of the fill layer based on the current IFillSettings.

public void Update()

Exceptions

exceptioncondition
ArgumentOutOfRangeExceptionThrown when an unknown FillType is encountered.

Examples

The following code demonstrates the support of Fill layers: Color fill.

[C#]

// Add support of Fill layers: Color fill
string sourceFileName = "ColorFillLayer.psd";
string exportPath = "ColorFillLayer_output.psd";

var im = (PsdImage)Image.Load(sourceFileName);
using (im)
{
    foreach (var layer in im.Layers)
    {
        if (layer is FillLayer)
        {
            var fillLayer = (FillLayer)layer;
            if (fillLayer.FillSettings.FillType != FillType.Color)
            {
                throw new Exception("Wrong Fill Layer");
            }
            var settings = (IColorFillSettings)fillLayer.FillSettings;
            settings.Color = Color.Red;
            fillLayer.Update();
            im.Save(exportPath);
            break;
        }
    }
}

The following code save images with different type of gradient and shows how to Aspose.PSD draws the gradient.

[C#]

string fileName = "FillLayerGradient.psd";
string sourceFile = fileName;
GradientType[] gradientTypes = new[]
{
    GradientType.Linear, GradientType.Radial, GradientType.Angle, GradientType.Reflected, GradientType.Diamond
};
using (var image = Image.Load(sourceFile))
{
    PsdImage psdImage = (PsdImage)image;
    FillLayer fillLayer = (FillLayer)psdImage.Layers[0];
    GradientFillSettings fillSettings = (GradientFillSettings)fillLayer.FillSettings;
    foreach (var gradientType in gradientTypes)
    {
        fillSettings.GradientType = gradientType;
        fillLayer.Update();

        string resultFile = fileName + "_" + gradientType.ToString() + ".png";
        resultFile = resultFile;
        psdImage.Save(resultFile, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
    }
}

The following code saves images with pattern Fill Layer and demonstrates how Aspose.PSD renders the pattern.

[C#]

string sourceFile = "sample.psd";
string outputFile = "sample_out.psd";
string outputPngFile = "sample_out.png";

// Load an existing image into an instance of PsdImage class
using (var image = (PsdImage)Image.Load(sourceFile))
{
    foreach (var layer in image.Layers)
    {
        if (layer is FillLayer)
        {
            var fillLayer = (FillLayer)layer;
            var settings = (IPatternFillSettings)fillLayer.FillSettings;
            settings.HorizontalOffset = -5;
            settings.VerticalOffset = 12;
            settings.Scale = 300;
            settings.Linked = true;
            settings.PatternData = new int[]
                                       {
                                           Color.Black.ToArgb(), Color.Red.ToArgb(),
                                           Color.Green.ToArgb(), Color.Blue.ToArgb(),
                                           Color.White.ToArgb(), Color.AliceBlue.ToArgb(),
                                           Color.Violet.ToArgb(), Color.Chocolate.ToArgb(),
                                           Color.IndianRed.ToArgb(), Color.DarkOliveGreen.ToArgb(),
                                           Color.CadetBlue.ToArgb(), Color.YellowGreen.ToArgb(),
                                           Color.Black.ToArgb(), Color.Azure.ToArgb(),
                                           Color.ForestGreen.ToArgb(), Color.Sienna.ToArgb(),
                                       };

            settings.PatternHeight = 4;
            settings.PatternWidth = 4;

            settings.PatternName = "$$$/Presets/Patterns/ColorfulSquare=Colorful Square New\0";
            settings.PatternId = Guid.NewGuid().ToString() + "\0";

            fillLayer.Update();
            break;
        }
    }

    image.Save(outputFile, new PsdOptions(image));
    image.Save(outputPngFile, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
}
