Hello

Im creating a toolbar (in this case in ProGUI, but i think question is the same) and i want to use a set of quality icons (i have it in PNG), something like:

My question is, how can i use it in imagebuttons or toolbar without lossing the nice shadow, transparency or even reflection efect? Is possible?

Thanks in advance

AFAIK, if you use 32bit icons with alpha the images will look just like that!

Its possible using PNG? (But keeping transparency and shadows)?

Yes, but it does only work on XP and newer.

You have to transform your image png into icon with alpha, it will work under XP with the activated Theme.

Photoshop? I tried with "Picture to Icon" trial and the shadow shows ugly (or maybe im a bad graphic manipulator

)

For the records (if anybody in the future want to solve this same problem).

Dld a freeware plugin that let you open any image with alpha channel and save it as ico. (i use it in photoshop and works like a charm)

As said above: you do not need to convert it to icon. Just use the png file directly.

I use the Axialis IconWorkshop trial to convert PNGs to Icons. It handles transparency
very well and you can specify the size quite straightforward.
Really worths a look...

And it shows the alpha?
Did you have an example (because i was not able to do it)?

Thanks

Code: Select all

UsePNGImageDecoder()

OpenWindow(0, 0, 0, 512, 384, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu)
CreateGadgetList(WindowID(0))
CreateToolBar(0, WindowID(0))
ToolBarImageButton(0, LoadImage(0, "c:\map.png"))

Repeat

No alpha here... I've always had to convert to .ico. Sometimes I cannot even get the fancy icons to show when in .ico format.

@Trond:

You are right!

Here is some modified code i test for using 48x48 images.

Code: Select all

;Modified from Sparkie's code

#TB_SETIMAGELIST = #WM_USER + 48
#TB_GETIMAGELIST = #WM_USER + 49

UsePNGImageDecoder() 

Procedure MakeLong(lo.w, hi.w)
  ProcedureReturn (hi * $10000) | (lo & $FFFF)
EndProcedure

;Your own 48x48 png images for toolbar with alpha showing
LoadImage(0, "F:\Inconos Alta Calidad\48x48\accept.png")
LoadImage(1, "F:\Inconos Alta Calidad\48x48\add.png")
LoadImage(2, "F:\Inconos Alta Calidad\48x48\attachment.png")

If OpenWindow(0, 0, 0, 350, 250,"", #PB_Window_SystemMenu |#PB_Window_SizeGadget | #PB_Window_ScreenCentered)
  hTB = CreateToolBar(0, WindowID(0))
  hOldIList = SendMessage_(hTB, #TB_GETIMAGELIST, 0, 0);
  hNewIList = ImageList_Duplicate_(hOldIList)
  ImageList_Destroy_(hOldIList)
  ImageList_SetIconSize_(hNewIList, 48, 48)
  SendMessage_(hTB, #TB_SETIMAGELIST, 0, hNewIList)
  SendMessage_(hTB, #TB_SETBITMAPSIZE, 0, MakeLong(48,48))
  SendMessage_(hTB, #TB_SETBUTTONSIZE, 0, MakeLong(48,48))
  SendMessage_(hTB, #TB_AUTOSIZE, 0, 0)
  ToolBarImageButton(0, ImageID(0))
  ToolBarImageButton(1, ImageID(1))
  ToolBarImageButton(2, ImageID(2))
  Repeat
    EventID = WaitWindowEvent()
    If EventID = #PB_Event_Menu
    EndIf
  Until EventID = #PB_Event_CloseWindow
  ImageList_Destroy_(hNewIList)
EndIf

Don't forget that if in XP they turn off themes then it will look bad.

You should have 2 sets of icons - one in 256 colours for if they don't have themes turned on.
