Insert text is not working

[jesseXu]

That is my code below. However the text is not showing. The image is showing properly.
Any help? Thanks.

func main() {
	var pt pdft.PDFt
	err := pt.Open("abc.pdf")
	if err != nil {
		panic("Couldn't open pdf.")
	}

	err = pt.AddFont("arial", "./arial.ttf")
	if err != nil {
		fmt.Println(err)
		return
	}

	err = pt.SetFont("arial", "", 14)
	if err != nil {
		panic(err)
	}

	err = pt.Insert("Hello World", 1, 100, 100, 100, 100, gopdf.Center|gopdf.Bottom)
	if err != nil {
		panic(err)
	}

	//read image file
	// pic, err := ioutil.ReadFile("./testlb.png")
	// if err != nil {
	// 	panic("Couldn't read pic.")
	// }

	//insert image to pdf
	// err = pt.InsertImg(pic, 1, 100, 100, 172.0, 49.0)
	// if err != nil {
	// 	panic("Couldn't insert image")
	// }

	pt.Save("hello.pdf")
}

I have the same issue @signintech

@jesseXu I managed to add text to PDF, I had to fork this repo and fix few things:

• Set RGB color, current repo doesn't support it
• Repo uses font Index prefix as F, in my case I had to use TT

You can check changes here - https://github.com/plutov/pdft, but I am not going to create a PR, since current project is very limited, so my PR won't really help. It requires the major rewrite.

@plutov I am also having issues getting things to behave as expected. Using your fork, though, my unit tests failed on an error: strconv.Atoi: parsing "F1": invalid syntax. Using the original source, my PDF opens with a warning that the file is corrupted. 🤔

@swoldemi if you look into my commit history there are few places where I replaced F with TT to work with my PDF file. You can revert it back if your PDF file uses F. You can check it by opening PDF file raw data and look for /Font.

@plutov Ah I see, thank you! (Btw, huge fan of your YouTube series)

@signintech any news on this?

I will clone the repo and try to use the same font as you in the example but just downloading a times roman TTF off the Internet did not work for me as per the example in the readme.
