Working with Timeline in Aspose.PSD for .NET

Introduction

In the dynamic world of graphic design and image manipulation, the ability to control and manipulate the timeline of images is crucial. Aspose.PSD for .NET provides a powerful solution with its Timeline class. This high-level feature enables users to make changes to the timeline of PsdImage, such as altering frame delay, editing layer states on specific frames, and more.

Prerequisites

Before diving into the exciting possibilities that the Timeline class offers, make sure you have the following prerequisites in place:

• Aspose.PSD for .NET Library: Ensure that you have the Aspose.PSD for .NET library installed. You can download it from the Aspose.PSD for .NET documentation.
• Document and Output Directories: Define the paths for your document and output directories in the code. Adjust the baseDir and outputDir variables according to your project structure. Now, let’s explore how to utilize the Timeline class step by step.

Import Namespaces

To start working with the Timeline class, import the necessary namespaces in your code:

using System;
using System.Collections.Generic;
using System.IO;
using Aspose.PSD.FileFormats.Core.Blending;
using Aspose.PSD.FileFormats.Psd;
using Aspose.PSD.FileFormats.Psd.Layers.Animation;

Step 1: Load PSD Image

Begin by loading the PSD image from the specified source file. Ensure that the source file path is correctly set:

string sourceFile = Path.Combine(baseDir, "image1219.psd");
using (PsdImage psdImage = (PsdImage)Image.Load(sourceFile))
{
    // Your code for further operations goes here
}

Step 2: Access the Timeline

Once the PSD image is loaded, access the Timeline using the following code:

Timeline timeline = psdImage.Timeline;

Step 3: Change Dispose Method

Manipulate the dispose method of a specific frame. In this example, we change the dispose method of frame 1:

timeline.Frames[0].DisposalMethod = FrameDisposalMethod.DoNotDispose;

Step 4: Adjust Frame Delay

Modify the delay of a particular frame. Here, we change the delay of frame 2 to 15:

timeline.Frames[1].Delay = 15;

Step 5: Edit Layer State

Change the opacity of ‘Layer 1’ on a specific frame. In this instance, we set the opacity to 50 on frame 2:

LayerState layerState11 = timeline.Frames[1].LayerStates[1];
layerState11.Opacity = 50;

Step 6: Move Layer

Move ‘Layer 1’ to the left-bottom corner on a specific frame (frame 3 in this example):

LayerState layerState21 = timeline.Frames[2].LayerStates[1];
layerState21.PositionOffset = new Point(-50, 230);

Step 7: Add New Frame

Add a new frame to the timeline:

List<Frame> frames = new List<Frame>(timeline.Frames);
frames.Add(new Frame());
timeline.Frames = frames.ToArray();

Step 8: Change Blend Mode

Alter the blend mode of ‘Layer 1’ on a specific frame (frame 4 in this case):

LayerState layerState31 = timeline.Frames[3].LayerStates[1];
layerState31.BlendMode = BlendMode.Dissolve;

Step 9: Save Changes

Apply the changes back to the PsdImage instance and save the modified PSD image:

psdImage.Save(outputPsd);

Step 10: Clean Up

Finally, clean up by deleting the temporary output file:

File.Delete(outputPsd);

Conclusion

In conclusion, the Timeline class in Aspose.PSD for .NET empowers developers to have granular control over the timeline of PSD images. Through a series of simple steps, you can manipulate frame properties, layer states, and more, opening up a realm of creative possibilities.
