Presentation Using Templates

This guide explains the process of creating a new presentation file from an existing template file using UniOffice.

Sample input #

Template file

Before you begin #

You should get your API key from your UniCloud account.

If this is your first time using UniOffice SDK, follow this guide to set up a local development environment.

Clone the project repository #

In your terminal, clone the examples repository. It contains the Go code we will be using for this guide.

git clone https://github.com/unidoc/unioffice-examples

To get the example navigate to the path presentation/use-template folder in the unioffice-examples directory.

cd unioffice-examples/presentation/use-template/

How it works #

The import section imports the necessary UniOffice packages and Go libraries. The init function sets the license key.

The main function which is defined in lines 25-90, generates the modified presentation file. In this function the template presentation file is opened and presentation.Presentation object is instantiated.

Lines 29-31 print the layout information of the slides. The for loop in lines 34-36, remove the existing template slides. Line 37, obtains the layout of the template file using ppt.GetLayoutByName("Title and Caption") and saves it to a variable for later use.

In lines 37-44, a new slide is created from the template layout. Then the place-holder’s title and body of the template file are modified by updating the text content in lines 46-49. The remaining code i.e. lines 51-86, adds new slides with paragraph texts and other properties from the template layout. Then finally, the presentation is written to file in line 87 using ppt.SaveToFile("mod.pptx").

Run the code #
