In this article, you will learn how to find layers and update the layer’s text or image within Photoshop’s PSD files dynamically using C# .NET.
PSD is the default format used by Adobe Photoshop for saving its documents in a multilayered structure where each layer contains the text, images, graphical objects, and other supported elements. There could be the case when you have a PSD template and you need to create several resultant images by populating the text and image layers within the template. An example of such a scenario is creating employee cards within an organization. In order to automate this process, I’ll show you how to:
C# Library to Find and Update PSD Layers
Aspose.PSD for .NET allows creating and modifying PSD files without installing Adobe Photoshop or Illustrator. The API can be handy in the scenario where you need to update PSD layers dynamically using C# or VB.NET. You can install the API using NuGet Package Manager or download and reference its DLLs manually.
Find and Update Text Layers in PSD Files using C#
Aspose.PSD for .NET allows you to find the desired layer in PSD files using the layer’s name. Once you find the layer, you can update its content. The following are the steps to find and update a text layer in a PSD file.
- Create an instance of the PsdImage class and initialize it with the PSD file’s path.
- Access the layers in the PSD using PsdImage.Layers property.
- Match each layer’s display name to get the desired layer into the TextLayer object.
- Update the text using TextLayer.UpdateText(String) method.
- Save the updated image using PsdImage.Save(String) method.
The following code sample shows how to find and update the text layer in the PSD file using C#.
Below is the screenshot of the input PSD file we have used in this example:
The following is the resultant PSD file having updated text layer:
Find and Update Image Layers in PSD Files using C#
In order to deal with graphical objects such as images, Aspose.PSD for .NET exposes Graphics class. This class is used to clear or draw the graphics within the PSD layers. The following are the steps to find a PSD layer and update its image.
- Create an object of the PsdImage class to load the PSD file.
- Find the layer in the PSD file from PsdImage.Layers object.
- Load the image you want to draw in the layer in a Stream object.
- Create a new Layer object and initialize it with the Stream object created in the previous step.
- Create an instance of the Graphics class and initialize it with layer to be replaced.
- Clear the layer using Graphics.Clear() method.
- Draw the image in the layer using Graphics.DrawImage(Image, Rectangle) method.
- Save the file using PsdImage.Save(String) method.
The following code sample shows how to find and update image layers in the PSD file using C#.
The following is the screenshot of the PSD file after updating the image layer using the above-mentioned code:
