CGo bindings to LibreOfficeKit
# Latest version of LibreOffice (5.2) is required
$ sudo add-apt-repository ppa:libreoffice/ppa
$ sudo apt-get update
$ sudo apt-get install libreoffice libreofficekit-dev
$ go get github.com/docsbox/go-libreofficekitThis example demonstrates how to convert Microsoft Office document to PDF
package main
import "github.com/dveselov/go-libreofficekit"
func main() {
office, _ := libreofficekit.NewOffice("/path/to/libreoffice")
document, _ := office.LoadDocument("kittens.docx")
document.SaveAs("kittens.pdf", "pdf", "skipImages")
document.Close()
office.Close()
}This example demonstrates how to get presentation slides titles
package main
import "fmt"
import "github.com/dveselov/go-libreofficekit"
func main() {
office, _ := libreofficekit.NewOffice("/path/to/libreoffice")
document, _ := office.LoadDocument("kittens.pptx")
slidesCount := document.GetParts()
for i := 1; i < slidesCount; i++ {
document.SetPart(i)
currentPart = document.GetPart()
fmt.Println("Current slide =", currentPart)
currentPartName = document.GetPartName(i)
fmt.Println("Current slide title =", currentPartName)
}
document.Close()
office.Close()
}Next example demonstrates how to use built-in LibreOffice rendering engine for creating page-by-page documents previews.
package main
import (
"os"
"fmt"
"unsafe"
"image"
"image/png"
)
import "github.com/dveselov/go-libreofficekit"
func main() {
office, _ := libreofficekit.NewOffice("/path/to/libreoffice")
document, _ := office.LoadDocument("kittens.docx")
rectangles := document.GetPartPageRectangles()
canvasWidth := libreofficekit.TwipsToPixels(rectangles[0].Dx(), 120)
canvasHeight := libreofficekit.TwipsToPixels(rectangles[0].Dy(), 120)
m := image.NewRGBA(image.Rect(0, 0, canvasWidth, canvasHeight))
for i, rectangle := range rectangles {
document.PaintTile(unsafe.Pointer(&m.Pix[0]), canvasWidth, canvasHeight, rectangle.Min.X, rectangle.Min.Y, rectangle.Dx(), rectangle.Dy())
libreofficekit.BGRA(m.Pix)
out, _ := os.Create(fmt.Sprintf("page_%v.png", i))
png.Encode(out, m)
out.Close()
}
