Android Question problem with Draw Bitmap from WebView

[Roberto P.]

Hello
I can not solve the problem of truncation of the page when I create image from web view.

is only generated image of the first page !? I saw that there are other identical reports and did various tests, but I could not find a way to solve the problem.
Can anyone help me please.

Example 1

    Dim bmp As Bitmap         =     mWV.CaptureBitmap()       
    Dim out As OutputStream
   
    out =    File.OpenOutput(mPathSavedReport, mFileSavedReport, False)
       
    bmp.WriteToStream(out, 100, "PNG")

    out.Close

Example 2

Dim Canvas1 As Canvas
Dim Bitmap1 As Bitmap
   
 Bitmap1.InitializeMutable(100dip, 100dip)
     
   Canvas1.Initialize2(mWV.CaptureBitmap()) 'this canvas will draw on the activity background
     
    SetDensity(Canvas1.Bitmap, 300)
     
   'Canvas1.DrawTextRotated("Pincode: 1234567", 150dip, 250dip, Typeface.DEFAULT_BOLD, 18, Colors.Black, "CENTER", -90)
   
   Dim Out As OutputStream

    Out = File.OpenOutput(File.DirRootExternal, "Test.png", False)
   
   Canvas1.Bitmap.WriteToStream(Out, 100, "PNG")
   Out.Close

Thank you

Have you tried to increase the WebView size (make it larger than the activity)?

 

[Roberto P.]

I did not understand the question?

 

[Erel]

Maybe I misunderstood the problem. Is the problem that the image created doesn't include the full web page?

 

[Roberto P.]

Erel
The problem is that the image is created of the only part visible in the device. In other words, if the web view has a higher height of the screen is generated the image of one area that you see.
I hope it is clear.
I think the problem depends on the image of the web view generation.
thank you

Can you upload a small project that demonstrates the problem?

 

[Roberto P.]

HI Erel,
make a small example is a complex task that requires very little time. I ask the great courtesy to tell me how to work the DrawBitmap function or send me the source of the same way I analyze where is the problem with our html.
Thanks so much

WebView.CaptureBitmap calls the native WebView.capturePicture api.
