Display image in Linux

Can someone share an example of how to display a graphic image when using the linux compiler? I have tried different things but have not been successful. Thanks!

Display it as a sprite.
Thats an easy way.

ImageGadget should also work, if you work without a screen. Or use the DrawImage()-function.

If you use PB under Windows as well then handle the graphic thing under Linux like you do it under Windows.

I still am unable to get a image to work on Linux PB projects, it must be something I am doing wrong... I am using Windows to write and test the code but it will not compile on Linux. Here is the code:

Code: Select all

Enumeration 1
  #Window_Form1
  #image
  #exit
EndEnumeration

FileName$ = "logo.bmp"
LoadImage(#image, FileName$)

Procedure.l Window_Form1()
  If OpenWindow(#Window_Form1,175,0,268,187,#PB_Window_SystemMenu|#PB_Window_ScreenCentered|#PB_Window_Invisible,"Linux Text")
    If CreateGadgetList(WindowID(#Window_Form1))
      ButtonGadget(#exit,105,145,60,20,"Exit")
      HideWindow(#Window_Form1,0)
      ProcedureReturn WindowID()
    EndIf
  EndIf
EndProcedure

If Window_Form1()
  
  StartDrawing(WindowOutput())
    imgid = UseImage(#image)
    DrawImage(imgid,10,50,48,48)
  StopDrawing()  
  
  quitForm1=0
  Repeat
    EventID=WaitWindowEvent()
    Select EventID
      Case #PB_Event_CloseWindow
        If EventWindowID()=#Window_Form1
          quitForm1=1
        EndIf

      Case #PB_Event_Gadget
        Select EventGadgetID()
          Case #exit
            End
            
        EndSelect
    EndSelect
  Until quitForm1
  CloseWindow(#Window_Form1)
EndIf
End

And the error when attemping to compile on Linux:

******************************************
PureBasic Linux x86 v3.81
******************************************

Loading external modules...
Starting compilation...
48 lines processed.
Creating the executable.
purebasic.o(.text+0x13f): In function `main':

- Feel the ..PuRe.. Power -

Is there an obvious syntax error? If it helps, "logo.bmp" has 256 colors and I am using RedHat 9

That is a PB bug, DrawImage(ImageID, x, y , [NewWidth, NewHeight])
with NewWidth and NewHeight isn't working.

Thanks for the reply. Does this mean you can not add image graphics if you are using the LInux version? If so, what is the correct way. I just want to add a image to my form.

I changed the line:

Code: Select all

DrawImage(imgid,10,50,48,48)

to

Code: Select all

DrawImage(imgid,10,50)

and now it compiles, however, when I execute the app is receive this error:

Gdk-ERROR **: BadMatch (invalid parameter attributes)
serial 51 error_code 8 request_code 146 minor_code 3

Any ideas?

I am still trying to get an image to display on my window when compiling on Linux. I have changeded distro's (Mandrake 10) since this was first posted and loaded the new version of PB (3.91) but I still do not get an image. There are no errors when compling the code - but I receieve this error on the command line when I execute the app: "DrawImage GTK not implemented"

I have both GTK 1.2 dev and SDL 1.2 dev loaded, am I missing something else?

Code: Select all

UseJPEGImageDecoder()
FileName$ = "logo.jpg"
LoadImage(1, FileName$)

OpenWindow(0,175,0,200,187,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"Linux PB Image")

StartDrawing(WindowOutput())
  imgid = UseImage(1)
  DrawImage(imgid,45,45,99,114)
StopDrawing() 
 
Repeat
  EventID=WaitWindowEvent()
Until EventID = #PB_Event_CloseWindow

End

This function is not implemented, I'm on it.

I'm just curious, had DrawImage worked before 3.91? :roll:

<edit>
I re-loaded 3.81 and DrawImage did not work either. It does not matter now, I was able to finally get an image to display using a ImageGadget. This had not worked on previous attempts with a different distro. I assume now that I did not have all of the required items for Linux. Who knows (who cares?)..

Code: Select all

UseJPEGImageDecoder()
FileName$ = "logo.jpg"
LoadImage(1, FileName$)

OpenWindow(0,175,0,200,187,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"Linux PB Image")
  CreateGadgetList(WindowID())
  ImageGadget(0,0,0,200,187,UseImage(1))
 
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
