Transparent area becomes black when use BUTTON...ADJUST

Transparent area becomes black when use BUTTON...ADJUST

Postby hua » Tue Dec 05, 2023 9:42 am

I created the button with this command
Code: Select all  Expand view  RUN
DEFINE BUTTON oBtnWhatsnew RESOURCE "whatsnewg","","","whatsnew"   OF oBar ADJUST


The image is alpha-blend image.
If I don't use ADJUST clause, the image is not resized but transparent area displays ok.
If I use ADJUST clause, the image's size is nice but the transparent area of the image becomes black like below

Image

How do I fix this? Using HArbour+FWH1912
The bar is repositioned before display using the command oBar:GoRight()

TIA

This is working fine for me here with FWH1912

Code: Select all  Expand view  RUN
#include "fivewin.ch"

function btnbar()

   local oWnd, oBar

   DEFINE WINDOW oWnd TITLE FWVERSION
   DEFINE BUTTONBAR oBar OF oWnd SIZE 80,80 RIGHT //2007
   DEFINE BUTTON OF oBar RESOURCE "ICHAT"    ADJUST
   DEFINE BUTTON OF oBar RESOURCE "FILES"    ADJUST
   DEFINE BUTTON OF oBar RESOURCE "POCKETPC" ADJUST
   DEFINE BUTTON OF oBar RESOURCE "IMAGE8"   ADJUST

   ACTIVATE WINDOW oWnd CENTERED

return nil
 


rc file
Code: Select all  Expand view  RUN
ICHAT    10 "..\bitmaps\alphabmp\ichat.bmp"
FILES    10 "..\bitmaps\alphabmp\files.bmp"
POCKETPC 10 "..\bitmaps\alphabmp\pocketpc.bmp"
IMAGE8   10 "..\bitmaps\pngs\image8.png"

Thank you for taking your time to create the sample.
I managed to create a reduced self-contained example that still shows the bug on my pc. Can you see whether that is the case or not on yours?

This is your definition of the buttonbar
Code: Select all  Expand view  RUN
 DEFINE BUTTONBAR oBar OF oWnd 3D size 110,66


1) Remove "3D" clause. This is creating problem of transparency. If you remove this clause, the images will be transparent.
But resizing makes the image ragged.

2) Add "GDIP" clause. This makes the resized image smooth.

Recommended code:
Code: Select all  Expand view  RUN
 DEFINE BUTTONBAR oBar OF oWnd GDIP SIZE 110,66 RIGHT


Please make this small change in buttonbar definition and let us know.

Code: Select all  Expand view  RUN
#include "fivewin.ch"

PROCEDURE main()

  local oBar, oBtnWhatsNew
  local oWnd

  DEFINE WINDOW oWnd TITLE "Test png in bar " + FWVERSION

  DEFINE BUTTONBAR oBar OF oWnd /*3D*/ GDIP RIGHT SIZE 110,66

  DEFINE BUTTON oBtnWhatsnew RESOURCE "WHATSNEWG","","","WHATSNEW"   OF oBar ;
      ADJUST FLAT

//  oBar:GoRight()

  ACTIVATE WINDOW oWnd CENTERED //MAXIMIZED

return
