Presentation with Custom Slide Sizes

In this guide, the process of creating slides with custom size using UniOffice will be explained step by step.

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/slide-size folder in the unioffice-examples directory.

cd unioffice-examples/presentation/slide-size/

How it works #

The import section imports the necessary Go libraries and UniOffice packages. The init function which is defined in lines 12-19, sets the license key before running the main function.

The main function is defined in lines 21-58. A new presentation is created in line 25 using ppt := presentation.New(). Then the for loop in lines 28-47, creates five slides using the AddSlide method of the presentation.Presentation object. The text boxes and related properties are then set in the lines 31-46.

In line 52, the presentation.SlideSize is obtained by calling the SlideSize method. Then the sizes are set using slideSize.SetSize(presentation.SlideScreenSize16x9) in line 53.

Finally, the presentation is validated and written to a file in lines 55-58 using:

if err := ppt.Validate(); err != nil {
	log.Fatal(err)
}
ppt.SaveToFile("slide-size.pptx")

Run the code #

Run this command to generate the presentation file.

go run main.go
