HELP with HPDF_Page_TextRect()

[Alexsander Santos]

Hi.

I am using libHaru in a Lua Script (AutoPlay Media Studio). Everything is ok BUT I cannot use the command HPDF_Page_TextRect().

Ex:

require "hpdf"

local pdf = hpdf.New()

if pdf then

  local page = hpdf.AddPage(pdf)

  hpdf.Page_SetSize(page, HPDF_PAGE_SIZE_A4, HPDF_PAGE_PORTRAIT)

  local height = hpdf.Page_GetHeight(page)

  local width = hpdf.Page_GetWidth(page)

 

  --Cabeçalho

  local image = hpdf.LoadPngImageFromFile(pdf,"esquerda.png")

  local image2 = hpdf.LoadPngImageFromFile(pdf,"direita.png")

  hpdf.Page_DrawImage(page,image, 30, height - 100, 138, 50.5)

  hpdf.Page_DrawImage(page,image2, width-30-140.5, height - 100, 140.5, 50,5)

  

  --Identificação

  local font = hpdf.GetFont(pdf, "Times-Bold", "WinAnsiEncoding")

  hpdf.Page_SetFontAndSize(page, font, 12)

  hpdf.Page_BeginText(page)

  hpdf.Page_TextOut(page, 30, height - 250, "Processo:")

  hpdf.Page_TextOut(page, 30, height - 275, "Interessado:")

  hpdf.Page_EndText(page)

This works very well. Now, I will try to add a long text in a rectangle and justify it.

 local ementa = "Esse é um texto muito específico e longo. Sua função é testar a funcionalidade de colocação de um texto justificado dentro de um determindo espaço de página. Vamos ver se funciona. Parece bom!";

  hpdf.Page_TextRect(page,0,0,200,200,HPDF_TALIGN_JUSTIFY,ementa);

hpdf.Page_TextRect does not work.The IDE says that the 7th argument must be 'string' but the 7th argument is the  HPDF_TextAlignment

Anybody helps?

Thanks and sorry about bad English

the correct syntax is:

HPDF_Page_TextRect( hPage, nLeft, nTop, nRight, nBottom, cText, nAlign ) -> hStatus

So you just swapped HPDF_TALIGN_JUSTIFY and ementa positions.
Please, try with:

hpdf.Page_TextRect(page,0,0,200,200,ementa,HPDF_TALIGN_JUSTIFY)

Best regards.

Hi Maurizio

Thank you for your answer. But, this makes the same error, now just saying that the erros is in the 6th argumen (image added)

I think it coud be an error in the version of libhpdf.dll (2.2). I tryed to compile 2.3, but I gave up. I looked for a precompiled last version of libhpdf.dll and hpdf.dll but I could not find.

Do you have another idea?

Thanks
