LuaHPDF

libHaru is a free, cross platform, open source library for generating PDF files, and LuaHPDF is a module that lets you programmatically create PDF files via Lua using this library.

LuaHPDF was developed by Kurt Jung as an interface to the Haru PDF Library. I have built libHaru 2.2.0.0, with zlib 1.2.8 and libpng 1.6.2, and finally compiled the LuaHPDF 1.3.0 module.

Using with AutoPlay Media Studio 8

Add the common.lua, hpdf.dll and libhpdf.dll files to your project, placing it into the Scripts folder. It then can be used on any page or dialog when needed.

Using with Setup Factory 9

Add the common.lua, hpdf.dll and libhpdf.dll files to the Primer Files of your project, so it will be decompressed into the runtime folder when the setup is executed. Then, where needed, load it.

Sample code for loading and using the module

require "hpdf"
require "common"

local pdf = hpdf.New()
if pdf then
	local page = hpdf.AddPage(pdf)
	local height = hpdf.Page_GetHeight(page)
	local width = hpdf.Page_GetWidth(page)
	local font = hpdf.GetFont(pdf, "Times-Roman")
	hpdf.Page_SetFontAndSize(page, font, 24)
	hpdf.Page_BeginText(page)
	hpdf.Page_TextOut(page, 60, height - 60, "Hello from Haru version " .. hpdf.VERSION_TEXT);
	hpdf.Page_EndText(page)

	local res = hpdf.SaveToFile(pdf, _TempFolder.."\\Hello.pdf");
	hpdf.Free(pdf)
	if (res == 0) then
		File.Open(_TempFolder.."\\Hello.pdf", _TempFolder, SW_SHOWNORMAL);
	else
		Dialog.Message("Error", "Could not save PDF document.", MB_OK, MB_ICONSTOP);	
	end
else
	Dialog.Message("Error", "Error creating PDF object.", MB_OK, MB_ICONSTOP);
end
