Hello at all

Is it possible to send directly an image in DATA to a WebGadget ??

Enumeration
 #Form0
 #Web0
 #Bouton0
 #Image
EndEnumeration

OpenWindow(#Form0, 216, 0, 397, 340, "New window ( 0 )",  #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar )
WebGadget(#Web0, 12, 18, 372, 291, "about:blank")
ButtonGadget(#Bouton0, 104, 315, 182, 20, "")

Repeat
  
 Evenement = WaitWindowEvent()
 
 If Evenement = #PB_Event_Gadget
  
  Select EventGadget()
    
   Case #Bouton0
    
    ImageID = CatchImage(#Image, ?FlagImage)
    SetGadgetText(#Web0, "???")
     
  EndSelect  
  
 EndIf 
 
Until Evenement = #PB_Event_CloseWindow

End
 
DataSection
 FlagImage:
 IncludeBinary "Image.jpg"
EndDataSection

Have a good day

Hi,

I think it is not possible to do it 'directly'.

In my opinion it is only possible to save the 'catched' image to the harddisk
Like this:

Code: Select all

Select EventGadget()
   Case #Bouton0
     ImageID = CatchImage(#Image, ?FlagImage)
     TmpImgFilename$ = GetTemporaryDirectory() + "test.bmp"
     SaveImage(#Image, TmpImgFilename$)
     SetGadgetItemText(#Web0, #PB_Web_HtmlCode, "<img src=" + #DQUOTE$ + TmpImgFilename$ + #DQUOTE$ + "></img>")
     
   Case #Web0
     If EventType() = #PB_EventType_DownloadEnd
      If Len(TmpImgFilename$)
        DeleteFile(TmpImgFilename$)
        TmpImgFilename$ = ""
      EndIf
     EndIf
  EndSelect

It seemed as though it was impossible.
Even with PB, it is not used, but sometimes it is still impossible to do things

I do like you show to me

So thanks a lot INFRATEC for your precious help

I wish you a good evening

I don't know if WebGadget supports it but there is a way

Hello Wilbert

Interesting, i don't know this tips

But apparently that not works with WebGadget
I have try this Data_URI_scheme

Code: Select all

Enumeration
 #Form0
 #Web0
 #Bouton0
EndEnumeration

OpenWindow(#Form0, 216, 0, 397, 340, "New window ( 0 )",  #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar )
WebGadget(#Web0, 12, 18, 372, 291, "about:blank", #PB_Web_Mozilla)
ButtonGadget(#Bouton0, 104, 315, 182, 20, "Charger le DATA")

Repeat
 
 Evenement = WaitWindowEvent()
 
 Select EventGadget()
   
   Case #Bouton0
         
    SetGadgetItemText(#Web0, #PB_Web_HtmlCode, "data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAABGdBTUEAALGP C/xhBQAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9YGARc5KB0XV+IA AAAddEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIFRoZSBHSU1Q72QlbgAAAF1J REFUGNO9zL0NglAAxPEfdLTs4BZM4DIO4C7OwQg2JoQ9LE1exdlYvBBeZ7jq ch9//q1uH4TLzw4d6+ErXMMcXuHWxId3KOETnnXXV6MJpcq2MLaI97CER3N0 vr4MkhoXe0rZigAAAABJRU5ErkJggg==")     
    
  EndSelect
 

Until Evenement = #PB_Event_CloseWindow

End

Normally a red point appears in Firefox...and not in WebGadget, in IE that not works too

Thanks when even for your help

Maybe it has to do with the version of the browser. IE8 supports the Data URI scheme but older IE versions don't.
I don't know if WebGadget relies on the version of IE that is installed.
On my Windows 7 both PB x86 and PB x64 show the dots correctly with or without the #PB_Web_Mozilla flag.

Try this one, it works here with mozilla or not:

Code: Select all

Enumeration
  #Form0
  #Web0
  #Bouton0
EndEnumeration

DataSection
  world: IncludeBinary #PB_Compiler_Home+"examples\sources\data\geebee2.bmp"
  worldend:
EndDataSection

*mem = AllocateMemory((?worldend-?world) * 1.35)

Base64Encoder(?world, ?worldend-?world, *mem, MemorySize(*mem))

a$ = "<html>"  + #CRLF$
a$ + "<head>"  + #CRLF$
a$ + "</head>" + #CRLF$
a$ + "<body>"  + #CRLF$  
a$ + "<a href="+Chr(34)+Chr(34)+"><img src="+Chr(34)+"Data:image/bmp;base64,"
a$ + PeekS(*mem)
a$ + Chr(34)+" alt="+Chr(34)+Chr(34)+" width="+Chr(34)+"128"+Chr(34)+" height="+Chr(34)+"128"+Chr(34)+" /></a>"+#CRLF$
a$ + "</body>" + #CRLF$      
a$ + "</html>" + #CRLF$  


OpenWindow(#Form0, 216, 0, 397, 340, "New window ( 0 )",  #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar )
WebGadget(#Web0, 12, 18, 372, 291, "about:blank")
ButtonGadget(#Bouton0, 104, 315, 182, 20, "Charger le DATA")

Repeat
  
  Evenement = WaitWindowEvent()
  
  Select EventGadget()
      
    Case #Bouton0
      
      SetGadgetItemText(#Web0, #PB_Web_HtmlCode, a$)
      
      
  EndSelect
  
  
Until Evenement = #PB_Event_CloseWindow

End

Yes you have right..i'm an old man...so i use an old browser IE7

I don't know if WebGadget relies on the version of IE that is installed.

Yes the WebGadget use the browser IE installed in the machine

I believe you have found the problem
