Some test text!
This guide will help you build your own PDFNet Go wrappers by binding a free trial of the PDFNet library to Go. It will also show you how to run PDFTron samples and integrate the PDFTron SDK into Go applications on Windows. Your free trial includes unlimited trial usage and support from solution engineers.
Clone the uncompiled PDFNet wrappers by executing
git clone https://github.com/PDFTron/PDFNetWrappers # Git clone the code.
Navigate to PDFNetWrappers/PDFNetC
and download the PDFNet C/C++ SDK into that directory. Ensure you obtain the right architecture for your Go interpreter. For example, if your interpreter is 64bit (which this guide will assume), execute
cd PDFNetWrappers/PDFNetC # Move to where we download PDFNetC.
Unzip PDFNetC64.zip, then execute
move PDFNetC64\Headers . # Move PDFNetC Headers/ into place.
move PDFNetC64\Lib . # Move PDFNetC Lib/ into place.
to move the PDFNetC libraries in place.
You can delete PDFNetC64.zip
to free up space.
Your /PDFNetC
folder should be laid out like this like this:
PDFNetC
├── Headers
├── Lib
├── PDFNetC64
└── README.txt
Make a build directory inside /PDFNetWrappers
and navigate to it. This guide will assume the build directory is called Build.
cd .. # Go back up /PDFNetWrappers.
md Build # Create a directory to create the Makefiles in.
cd Build # Move to that directory.
Execute make
.
cmake -G "MinGW Makefiles" -D BUILD_PDFTronGo=ON .. # Create the pdftron directory under Build/PDFTronGo/ directory.
If all goes well, you should get a message which reads:
Build files have been written to ~/PDFNetWrappers/Build
Copy pdftron
directory followed by go install
.
cd PDFTronGo # Move to that directory.
go env # Find the go path in GOPATH environment variable.
xcopy /E pdftron GOPATH\src\pdftron\ # Copy pdftron directory to GOPATH/src directory.
cd GOPATH\src\pdftron # Move to pdftron directory.
go install # Build and install pdftron package for Go
You are now ready to run the samples or integrate PDFTron SDK into your own application.
Run a specific sample
GO
folder in the sample, for example /Samples/AddImageTest/GO
and execute ./RunTest.bat
Run all samples
To run all tests, navigate to /Samples
and execute:
cd ../Samples # Move to the Samples directory.
./runall_go.bat # Run all Go code samples, using the new wrappers.
The tests will run one by one.
/Samples/TestFiles/Output
This section will show you how to use our SDK to create a simple PDFTron "Hello World!" application. It will create a document with one blank page and save it as a linearized PDF in its running directory.
/Samples
directory and make a new directory called myApp
(if it does not exist already). This guide will assume your application is named myApp. For organization, create a new directory inside myApp
called GO
.Navigate inside that GO
directory and create a new GO file called myApp.go
. Open it with your favorite text editor and paste this into it:
package main
import (
"fmt"
. "pdftron"
)
func main(){
PDFNetInitialize() // PDFNet must be initialized before accessing any PDFTron API
doc := NewPDFDoc()
page := doc.PageCreate() // Start a new page
doc.PagePushBack(page) // Add the page to document
doc.Save("output.pdf", uint(SDFDocE_linearized)); // Save the document as a linearized PDF
doc.Close()
}
Run your application by executing go run myApp.go
. Make sure that your interpreter can find the PDFNetC library. If all goes well, your console should output:
PDFNet is running in demo mode.
Permission: write
Hello World!
Check the output.pdf
that the program output in the same directory. It should be a PDF with one blank page.
