Gluing bitmaps

[Natter]

It seems that under the FW2010 version, the ability to label one bitmap on another has stopped working

Code: Select all  Expand view

local bmp1:="C:\pct1.bmp", bmp2:="C:\pct2.bmp"
local hBmp
local img:={FW_ReadImage( nil, bmp1 ), ; // [3],[4] are width and height
                  FW_ReadImage( nil, bmp2 )}

  hBmp := FW_MakeYourBitmap( img[1,3]+10, img[1,4]+6, ;
                  { |hDC, w, h| PaintOverlay( hDC, w, h, img) } )

  PalBmpFree( img[1] )
  PalBmpFree( img[2] )

  FW_SaveImage( hBmp, pr1 ) // cSave can be bmp,jpg,png

When executing the function FW_SaveImage, I get an error:
Error description: Error BASE/1074 Argument error: <=

[ 1] = P 0x135B0000
[ 2] = N 32

no use la unidad C:\

Paths to C files:\pct1.bmp and C:\pct1 .bmp are written for example only.

do you run the .exe as adm?

Regards, saludos.

[Natter]

Karinha, this option worked for years on many computers until I updated the FW version. FreeImage.dll It has nothing to do with it (I checked)

Mr. Natter

I understand you are using xHarbour. Not Harbour.
You are getting the run time error at this line while executing this line in function LoadFreeImage() in image.prg

Code: Select all  Expand view

     if hLib <= 32
 

This is because while using xHarbour, hLib is a pointer but not numeric.
I also agree that this problem was not there in earlier versions. It is because some changes are made in the functions,
LoadLibrary() and FreeLibrary() in this version.

We regret the inconvenience.

Please replace the existing
function LoadFreeImage( cResName )
in the "image.prg"
from lines 492 to 514

with this revised function and try

Code: Select all  Expand view

function LoadFreeImage( cResFile )

   DEFAULT cResFile := If( IsExe64(), "freeimage64.dll", "freeimage.dll" )

   if hLib == nil

      #ifdef __CLIPPER__
         hLib = LoadLib32( cResFile )
      #else
         hLib = LoadLibrary( cResFile )
      #endif

      if ValType( hLib ) == "P"
         hLibP = hLib
         hLib = PtrToNum( hLib )
      endif  

      if hLib <= 32
         if !( PROCNAME( 1 ) == "FREEIMAGEISLOADED" )
            MsgAlert( "Cannot load " + If( IsExe64(), "FreeImage64.dll", "FreeImage.dll" ) )
         endif
         hLib  = 0
      endif

   endif

return hLib
 

Please try with this change.
Honestly, I am yet to try. I will also check and get back if necessary.

[Natter]

I tried to run the Load Free Image() function in my program.
I received a message about the absence of the hLib variable.
If you set STATIC hLib, the compilation message will appear - STATIC declaration follows executable statement

[Antonio Linares]

Dear Natter,

static hLib must be declared before any code above

[Natter]

Yes, I declared the hLib variable. But the following error occurs:

Dear Natter,

Please recompile FWH\source\classes\image.prg using this dll.ch. Please update FWH\include\dll.ch:

If you don't know how to do it, or you prefer to use ours libs, then I will send them to you

[Natter]

Antonio, please, send them to me !

[Antonio Linares]

Already sent to your email

[Natter]

I replaced the libraries.

Could you please provide a small PRG to test it here ?

How to reproduce the error ?
