Gracias mil

function main()
local oWnd

define window oWnd
activate window oWnd on paint( BarCode( hDC ) )

return nil

function BarCode( hDC )

   local cCode := "testing from fivewin"
   local hBrush := CreateSolidBrush( 0 )

   hZebra := hb_zebra_create_pdf417( cCode, NIL )
   hb_zebra_draw( hZebra, {| x, y, w, h | FillRect( hDC, { y, x, y +  h, x + w }, hBrush ) }, 5, 5, 1, 4 )

   hb_zebra_destroy( hZebra )

   deleteobject( hBrush )

return(nil)

Mira yo lo hago asi

#include "fivewin.ch"
#include "codebar.ch"

static oCode, oWndP

function Main()

local oMenu

oCode := TCodeBars():New()

oMenu = BuildMenu()
**

BuildCode( CODEBAR_DATAMATRIX, "DataMatrix ")

* define window oWndP menu oMenu
* activate window oWndP &&ON INIT (BuildCode( CODEBAR_DATAMATRIX, "DataMatrix ", oWndP:end() ))

return nil

function BuildMenu()

local oMenu

menu oMenu
menuitem "CodeBar"
menu
menuitem "EAN13" action( BuildCode( CODEBAR_EAN13, "477012345678" ) )
menuitem "EAN8" action( BuildCode( CODEBAR_EAN8, "1234567" ) )
menuitem "UPCA" action( BuildCode( CODEBAR_UPCA, "01234567891" ) )

menuitem "PDF417" action( BuildCode( CODEBAR_PDF417, "PDF17" ) )
menuitem "DATAMATRIX" action( BuildCode( CODEBAR_DATAMATRIX, "DataMatrix ") )
endmenu
endmenu

return oMenu

function BuildCode( nCode, cCode, nFlags )

* local hDC := oWndP:GetDC()

default nFlags := 0


oCode:Reset()
if nCode < CODEBAR_PDF417
oCode:nHeightCode = oCode:nHeight - 50
oCode:nWidthCode = 1.5
else
oCode:nHeightCode = 3
oCode:nWidthCode = 1
endif
oCode:SetType( nCode )
oCode:SetCode( cCode )
oCode:SetFlags( nFlags )
oCode:Build()

* DrawBitmap( hDC, oCode:hCodeBar, 0, 0 ) && aqui lo pinta en la pantalla

DrawBitmap( oCode:hCodeBar,10, 10 ) && aqui lo mando a un archivo file.bmp de 10x10 tam
hDib := DibFromBitmap(oCode:hCodeBar )
DibWrite( "file.bmp" , hDib )

* oWndP:ReleaseDC()
* oWndP:END()

return nil

Gracias mi amigo, eso funciona perfectamente con la librería externa de zebra y con XHarbour
estoy migrando Harbour 3.2.0, que tiene la librería hbzebra y el ejemplo es el que puse arriba,, y no veo la manera de pasarlo a un file..

Un abrazo..

Yo tengo una función que te puede ser util....
Usa gdiplus y no se si te faltará alguna funcion gdiplus ( en caso de faltar pidela )
El codigo que te pongo es para qrcode pero lo he comentado y te lo he puesto para pdf417. No lo he probado con pdf417 .

   local hZebra := hb_zebra_create_pdf417( cVar, NIL )
   LOCAL nFlags
   local nWidth, nHeight
   local hBmp, hGraf
   local hBrush  := GdiPlusNewSolidBrush( 255, 255, 255, 255 )

   GdiPlusDeleteBrush( hBrush )
   GdiPlusDeleteBrush( hBrush2 )

Gracias,,,, funciona ok,,,, y como cambio el color en gdi???
Salu2

Salu2

Puedes utilizar los colores que necesites solo cambiandolo aqui ...
hBrush2 es el color del codebar
hbrush el color del fondo

local hBrush  := GdiPlusNewSolidBrush( 255, 255, 255, 255 )

Mr. Mastintin, where are this functions?

Code: Select all | Expand

 nWidht  := hb_Zebra_GetWidth ( hZebra, nLineWidth, nLineHeight, nFlags )
   nHeight := hb_Zebra_GetHeight( hZebra, nLineWidth, nLineHeight, nFlags )

THANKS!

[byte-one]

Christobal, please try QR-Code with data "aa1"! You can see, that the last block is not to see! It seems as a bug in zebra. DATAMATRIX is ok.

[cnavarro]

Sorry, I do not understand well

[byte-one]

Cristobal, please try with this code! The code are made ok, but the function hb_zebra_Getwidth(...) returns wrong width-result. I found, that this behavoir is on mode "alphanumeric" in the QR-sourcecode but not in all cases.
