Bank Account Statement

In this guide creating a sample bank statement document will be shown.

Before you begin #

You should get your API key from your UniCloud account if you don’t have any yet.

If this is your first time using UniPDF SDK, follow this guide to setup 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/unipdf-examples.git

Navigate to the templates/bank-account-statement folder in the unipdf-examples directory.

cd unipdf-examples/templates/bank-account-statement

How it works #

UniPDF packages and other libraries are imported in the import section in lines 10-24. The init function in lines 26-35 loads the license key from environment to authenticate library request.

The main function in lines 37-125 creates the file using templates and writes the document to file. In lines 42-51 the template file and json file are read using mainTpl, err := readTemplate("templates/main.tpl") and statement, err := readAccountStatement("account_statement.json") respectively. The template options object is created in lines 54-87 using creator.TemplateOptions. In line 89 the main template is drawn using c.DrawTemplate.

In lines 94-112 a function defined for drawing header and footer elements.

In line 114-119 the footer and header are drawn by using the predefined function. Finally the pdf document is written to file in lines 122-124 using the following code.

if err := c.WriteToFile("unipdf-bank-account-statement.pdf"); err != nil {
		log.Fatal(err)
	}

The readTemplate function reads the template function and returns io.Reader buffer. In lines 145-190 AccountStatement object is defined to represent the data used for the document. The readAccountStatement function defined in lines 194-207 decodes the data in json to an AccountStatement object.

Run the code #

Use the following command to run the code.

go run pdf_bank_account_statement.go
