Presentation with Custom Paragraph Properties

This guide will show you how to add borders to paragraphs and control the type, size and color.

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

Navigate to the path presentation/complex folder in the unioffice-examples directory.

cd unioffice-examples/presentation/complex/

How it works #

In the above sample code, the necessary packages are imported in lines 4-13. Then the metered license key is set inside the intit function, i.e. in lines 15-22.

The main function which contains the code used for generating the desired document is defined in lines 26-80. In this function, a new presentation.Presentation object is created in line 27 using presentation.New(). Then in lines 29-37, an image is loaded from file and added to the Presentation object using:

imgColor, err := common.ImageFromFile("gophercolor.png")
irefColor, err := ppt.AddImage(imgColor)

In line 39, a new slide is created using ppt.AddSlide(). Then the image is added to the slide in lines 41-43. In line 45 a new presentation.TextBox is created using slide.AddTextBox(). The text anchoring and paragraph alignments are set afterwards in lines 46-49.

From line 55 though line 60, the properties of the TextBox objects are set using:

tb.Properties().SetGeometry(dml.ST_ShapeTypeChevron)
tb.Properties().SetFlipHorizontal(true)
tb.Properties().SetSolidFill(color.LightBlue)
tb.Properties().LineProperties().SetWidth(0.125 * measurement.Inch)
tb.Properties().LineProperties().SetSolidFill(color.DarkBlue)
tb.Properties().SetPosition(2.5*measurement.Inch, 0.5*measurement.Inch)

Another TextBox is created in lines 62. Then the properties and contents of the TextBox are set using the for loop in lines 64-74. Finally, the presentation is saved to a file in line 79 using ppt.SaveToFile("complex.pptx").

Run the code #

Run this command to create the presentation using the example code.

go run main.go
