Adding Gradient Effects to Images in Aspose.PSD for .NET

Introduction

Enhancing images with gradient effects can add a captivating dimension to your visual content. Aspose.PSD for .NET provides a powerful platform for incorporating gradient overlays into your images. In this tutorial, we’ll guide you through the process of adding gradient effects using Aspose.PSD for .NET.

Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites in place:

• Aspose.PSD for .NET Library: Download and install the library from Aspose.PSD for .NET Documentation.
• .NET Environment: Ensure you have a working .NET environment set up on your machine.

Import Namespaces

Begin by importing the necessary namespaces into your project:

using Aspose.PSD.FileFormats.Psd;
using Aspose.PSD.FileFormats.Psd.Layers.FillSettings;
using Aspose.PSD.FileFormats.Psd.Layers.LayerEffects;
using Aspose.PSD.ImageLoadOptions;
using System;
using Aspose.PSD.FileFormats.Core.Blending;
using System.IO;

Step 1: Load the Image and Define Paths

// The path to the documents directory.
string SourceDir = "Your Document Directory";
string OutputDir = "Your Output Directory";

string sourceFileName = Path.Combine(SourceDir, "GradientOverlay.psd");
string exportPath = Path.Combine(OutputDir, "GradientOverlayChanged.psd");

var loadOptions = new PsdLoadOptions()
{
    LoadEffectsResource = true
};

Step 2: Assert Initial Settings

Ensure that the initial settings of the gradient overlay are as expected:

using (var im = (PsdImage)Image.Load(sourceFileName, loadOptions))
{
    var gradientOverlay = (GradientOverlayEffect)im.Layers[1].BlendingOptions.Effects[0];

    // Assertion checks for initial settings
    // ...

    // Color Points
    // ...

    // Transparency points
    // ...
}

Step 3: Modify Gradient Overlay Settings

Adjust the gradient overlay settings according to your preferences:

// Test editing
settings.Color = Color.Green;

gradientOverlay.Opacity = 193;
gradientOverlay.BlendMode = BlendMode.Lighten;

settings.AlignWithLayer = false;
settings.GradientType = GradientType.Radial;
settings.Angle = 45;
settings.Dither = true;
settings.HorizontalOffset = 15;
settings.VerticalOffset = 11;
settings.Reverse = true;

// Add new color point
// ...

// Change location of previous point
// ...

// Add new transparency point
// ...

// Change location of previous transparency point
// ...

im.Save(exportPath);

Step 4: Validate Edited File

Check if the modifications were applied successfully:

// Test file after edit
using (var im = (PsdImage)Image.Load(exportPath, loadOptions))
{
    var gradientOverlay = (GradientOverlayEffect)im.Layers[1].BlendingOptions.Effects[0];
    try
    {
        // Assertion checks for modified settings
        // ...
    }
    catch (Exception e)
    {
        string ex = e.StackTrace;
    }
}
