Classe FreeImage de xharbour + fwh

Rossine · Post by **Rossine** » Mon Dec 11, 2006 7:34 pm

Olá,

No xharbour existe uma classe para acessar a freeimage.dll, só que, quando incluo o "freeimage.ch", como no programa abaixo é gerado os erros abaixo:

#include "fivewin.ch"
#include "FreeImage.ch"
#include "common.ch"

function Main()

local oWnd, oBmp

DEFINE WINDOW oWnd TITLE "SaveToBmp"

ACTIVATE WINDOW oWnd

return nil

Application
===========
Path and name: C:\teste\imag8.exe (32 bits)
Size: 1,565,184 bytes
Error occurred at: 12/11/06, 17:30:40
Error description: Error BASE/2023 Argument error: SizeOfCStructure
Args:
[ 1] = A { ... }

Stack Calls
===========
Called from: => HB_SIZEOFCSTRUCTURE(0)
Called from: cstruct.prg => __ACTIVESTRUCTURE(150)
Called from: => __INIT_BITMAPINFOHEADER$(0)

Isto é alguma incompatibilidade ? Como corrigir isto ?

Obrigado,

Rossine.

Hello Silvio,

I am trying to use the class \xharbour\contrib\freeimage

Best regards.

Olá,

Esta classe realmente é muito boa e tem várias funções para se trabalhar com a freeimage, mas não consigo usá-la junto com FWH.

Veja um exemplo abaixo:
