I have problem to converte a Png file on Jpg, and then this jpg to Bmp on Windows Seven
I save the images in a ". \ Temp" folder.
After performing the conversion I use the images in a combobox and in Windows Seven IO I see black lines on the images but in reality there are no images saved in a folder ". \ Temp"

you can see on first picture some black line I not Know why ...

to create jpg from Png I made
hBmp := FW_ReadImage( nil, cFile )[ 1 ]
hNew := FW_TransformBitmap( hBmp, NIL, 40)
ext:= aExt[ntipo]
cNewfile:= cFolderTemp+cNewName+ext
FW_SaveImage( hBmp,cNewfile ,90)

then to converte jpg to BMP I made

cFileBmp:= savetobmp(cfileJpg)

Function Savetobmp(cfile)
Local hBmp := FW_ReadImage( nil, cfile )[ 1 ]
FW_SaveImage( hBmp, cfile+".Bmp",90 )
Return cfile

on windows 10 it runs perfectly, on windows Seven How I can resolve ?

What if you try this way?

FW_SaveImage( "file.png", "file.jpg", nQuality )
FW_SaveImage( "file.png", "file.bmp )

Nages, I tried it but bmp images are created perfectly then when you use the combox you see black lines
in the snapshot below you can see that the selected image has black lines, the image to be selected is shown very well

I made a small test

Code: Select all | Expand

#include "fivewin.ch"

Function test()
   local oDlg
   local oCbx
   local nIcoElemento := 1
   local aGet[1]
   local aElementiItems:= {}
   Local aFiles:={"ombrellone_verde.png",;
                  "Palma_verde.png",;
                  "cabina_verde.png",;
                  "tenda_verde.png"}

   local aBmpCombo:=Convert_2_Bmp(aFiles)

           for n= 1 to  Len(aBmpCombo)
             AaDd(aElementiItems,"")
           next


  define dialog oDlg  size 400,400 title "Test combo Images"
   @ 2,5 COMBOBOX aGet[1] VAR nIcoElemento Items aElementiItems ;
            BITMAPS aBmpCombo SIZE 50,120 PIXEL  of oDlg
  activate dialog oDlg centered

    return nil
//-------------------------------------------------------------------//
Function Convert_2_Bmp(aFiles)
   local atmp:= {}
   local n
   local nQuality:= 90

             For n= 1 to 4
               cNewFile:="temp_"+(ltrim(str(n)))+".bmp"
               FW_SaveImage( aFiles[n],  cNewFile,nQuality )
               aadd( atmp, cNewFile )
             next n

        return atmp
//-------------------------------------------------------------------//

I sent you my images via MAIL

So, you have problem in converting to bmp?

One question:
Why do you want to convert png into bmp? You can use png directly with combobox now.

>You can use png directly with combobox now

FROM WHEN ?

i MADE

Local aFiles:={"ombrellone_verde.png",;
"Palma_verde.png",;
"cabina_verde.png",;
"tenda_verde.png"}

@ 2,5 COMBOBOX aGet[1] VAR nIcoElemento Items aElementiItems ;
BITMAPS aFiles SIZE 50,120 PIXEL of oDlg

AND IT IS THE SAME

return nil

I do not see any lines.
I tested on windows 10

obviously the problem I do not have on windows 10, but in windows Seven as I specified in the first post

so I tried your test on Windows Seven

Please select the tropical selection, when you select this you'll see the line black on bitmap
