Problem with conversion Image on W7

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?
Code: Select all
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
#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

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
