LuaHPDF + libHaru

[Ulrich]

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.

A sample project features 16 different example routines, each showing different capabilities of the libHaru PDF library.

Hi Ulrich,
What a great tool and demo!! Awsome

This seems to be a great tool and I would like to know if it would be possible to create a pdf out of an webpage?
Do you happen to know that?

Kind regards,
Eric.

If you want to print a web page as a PDF, then the normal approach would be using a PDF printer. In the installer of your product, you would include a PDF printer, like PDFlite, CutePDF or any similar product. Afterwards, you would print the content using this device, which then creates the PDF document for you.

Ulrich,

I don't know how much experience you have with this, but I'm a bit lost and was hoping I could ask you something.

I've successfully made a header, body, and signature, which I'm pulling from a rich text box in AutoPlay; however, I can't figure out how to make the body text dynamically add a second page if it needs to. I'm using TextRect to draw the text, because it was the only way I could get the text to wrap.

Nice work Ulrich.

Is it possible to make bold and color font ?

I tried this but it didnt really work ;

hpdf.Page_BeginText(page)
hpdf.Page_SetTextRenderingMode(page, "HPDF_FILL")
hpdf.Page_MoveTextPos(page, 138, hpdf.Page_GetHeight (page) - 862)
hpdf.Page_SetTextLeading(page, 12)
hpdf.Page_ShowText(page, "JANUARY")
hpdf.Page_EndText(page)

[Ulrich]

For bold text, use a bold font name, like "Helvetica-Bold", etc. or load a TTF corresponding to a bold font, with LoadTTFontFromFile().

The "Text" button of the demo shows how to make colored text on the page, use the Page_SetRGBFill() function.

[jakabo]

how would be possible to center or right align the text in Rectangle ?

	hpdf.Page_GSave(page)  	
              hpdf.Page_Rectangle(page, 135, hpdf.Page_GetHeight (page) - 870, 100, 25) 
	hpdf.Page_Clip(page)
	hpdf.Page_Stroke(page)
	hpdf.Page_SetFontAndSize(page, font2, 13)
	
	hpdf.Page_BeginText(page)
	hpdf.Page_MoveTextPos(page, 138, hpdf.Page_GetHeight (page) - 862)
	hpdf.Page_SetTextLeading(page, 12)
	hpdf.Page_ShowText(page, "JANUARY")
	hpdf.Page_EndText(page)
	hpdf.Page_GRestore(page)

I am tring to list data in my xml file to pdf but it is coming over eachother as seen in the screenshot, why is that ?




Xml data:

<root><coming>
<person><name>TEST 1 </name><surname>ROP1</surname><company>INDIGO1</company><date>21.06.2013</date></person>
<person><name>TEST 2</name><surname>ROP2</surname><company>INDIGO2</company><date>22.06.2013</date></person>
<person><name>TEST 3</name><surname>ROP3</surname><company>INDIGO3</company><date>23.06.2013</date></person>
</coming></root>

Code :

n_lx = XML.Count("root/coming", "person");
local t_Links = {};
for i = 1, n_lx do
  local s_xml_subpath = "root/coming/person:"..i.."/";
  local name = XML.GetValue(s_xml_subpath.."name");
  local surname = XML.GetValue(s_xml_subpath.."surname");
  local company = XML.GetValue(s_xml_subpath.."company");
  local date = XML.GetValue(s_xml_subpath.."date");
	hpdf.Page_GSave(page)  	
    hpdf.Page_Rectangle(page, 1450, hpdf.Page_GetHeight (page) - 150, 280, 100)    
	hpdf.Page_Clip(page)
	hpdf.Page_Stroke(page)
	hpdf.Page_SetFontAndSize(page, font, 10)
	
	hpdf.Page_BeginText(page)
	hpdf.Page_SetRGBFill(page, 0.1, 0.5, 0.1)
	hpdf.Page_MoveTextPos(page, 1528, hpdf.Page_GetHeight (page) - 70)
	hpdf.Page_SetTextLeading(page, 12)
	hpdf.Page_ShowText(page, name)
	hpdf.Page_ShowTextNextLine(page, surname)
	hpdf.Page_ShowTextNextLine(page, company)
	hpdf.Page_ShowTextNextLine(page, date)
	hpdf.Page_EndText(page)
	hpdf.Page_GRestore(page)

end

You should not call Page_MoveTextPos() inside the loop.

Please refrain from sending PMs regarding open discussions.

Ulrich

[jakabo]

Yes but if i dont use Page_MoveTextPos() in loop how will I loop the text position ?

[jakabo]

Why is it asking if i want to save the pdf ?
It is already saved ;

local res = hpdf.SaveToFile(pdf, "c:\\Test.pdf");
hpdf.Free(pdf)
