Haru Pdf is based on pixels for default resolution 72dpi. Also note the coordinates that are different from HMG HPDF.
http://libharu.sourceforge.net/graphics.html
So 210mm is: 210/25.4 * 72 = 595,275591 px
and 297mm is: 297/25.4 * 72 = 841,889764 px
Look at grid on page 1.
At sample on page 2, value 400 corresponds lower-left corner of the grid in pixels (nRow), so 400/72 * 25.4 = 141,111111 mm, counting from bottom of the page.

Haru Pdf is based on pixels for default resolution 72dpi. Also note the coordinates that are different from HMG HPDF.

edk, text along with the grid is not accentuating, I already added _HMG_HPDF_SetEncoding ("WinAnsiEncoding") but it does not work

You need to do:
HPDF_GetFont gets the handle of a corresponding font object by specified name and encoding.

Code: Select all

Local cEncoding := _HMG_SYSDATA[ 150 ] [ 10 ]       //Value of "SET HPDFDOC ENCODING TO".   "SET HPDFDOC ENCODING TO" set _HMG_HPDF_SetEncoding
font := HPDF_GetFont (pdf, "Helvetica", cEncoding)
Good luck to you.

it does not work so I need the horizontal text to be right-aligned just with HPDF_Page_SetTextMatrix? But the accent does not work.
MÃ-nimo: 119 -> "Mínimo: "


Local Pdf := _HMG_SYSDATA[ 150 ][ 1 ]
Local Page := _HMG_SYSDATA[ 150 ][ 7 ]
Local cEncoding := _HMG_SYSDATA[ 150 ] [ 10 ]

ofont := HPDF_GetFont (Pdf, cFont, cEncoding)
HPDF_Page_SetFontAndSize (Page, ofont, nFontSize)

nAngle := 0
nRad := nAngle / 180 * 3.141592 //radian value
nTextWidth := HPDF_Page_TextWidth( page ,"Mínimo: " +alltrim(str(nMim) ))

nxPos:= 85 - (nTextWidth* cos (nRad)) // posição coluna do texto
nyPos := nRow + nMim
HPDF_Page_BeginText (page)
HPDF_Page_SetTextMatrix ( page , cos ( nRad ), sin ( nRad ), -sin ( nRad ), cos ( nRad ), nxPos , nyPos - nFontSize/2 + .75 ) // nyPos = posicao Linha(Row)
HPDF_Page_ShowText (page, "Mínimo: "+alltrim(str(nMim)))

I don't see the problem with accents:

Code: Select all

SET HPDFDOC ENCODING TO "WinAnsiEncoding"

Do you have a .prg file saved in UTF-8? Perhaps this is a problem.
Prg in ANSI works fine:

Hi Kryzstof,

Is this text right: MĂ-nimo ?

And should the prg be save ad UTF-8 ? I think it must.
I download both and they show "MĂ-nimo".

Serge
