iOS Question Bitmap question

[mrossen]

Hi

I use this snip of code in my B4A app,

Canvas1.Initialize(ImageViewPinCard) 'this canvas will draw on the activity background
   
    Canvas1.DrawText(Device, 14dip, 50dip, Typeface.DEFAULT, 10, Colors.Black, "LEFT")
    Canvas1.DrawText("S/N: " & SN, 14dip, 60dip, Typeface.DEFAULT, 6, Colors.black, "LEFT")
    Canvas1.DrawText("PIN Code: " & PinCode, 14dip, 70dip, Typeface.DEFAULT_BOLD, 7, Colors.Black, "LEFT")

    Bitmap1.Initialize3(Canvas1.Bitmap)

I would like to use it in B4i but it seems not to have "Bitmap1.Initialize3)

Another problen is "Typeface.DEFAULT" is not accepted,

Anyone with come experince on this ?

It seems that it is not possible to initialize a canvas directly to a bitmap but only to views.
You could use an ImageView instead.

The DrawText routine is a bit different in B4i.
The line below

Canvas1.DrawText(Device, 14dip, 50dip, Typeface.DEFAULT, 10, Colors.Black, "LEFT")

must be

Canvas1.DrawText(Device, 14dip, 50dip, Font.CreateNew(10), Colors.Black, "LEFT")

Font.CreateNew creates a Font object based on the default font and 10 is the size.


And replace

Bitmap1.Initialize3(Canvas1.Bitmap)

by

Bitmap1 = Canvas1.CreateBitmap)
