Android Question Bitmaps less bulky for printing purposes ?

[MitchBu]

I am still struggling with printing. PDF printing creates random errors, so I am exploring bitmap printing.

But to get to 300 dpi requires a picture 2550x3300 for a letter size printing. As a result, the resulting default bitmap format chokes the printer.

Would it be possible to use a less memory hungry format, as described here:
https://developer.android.com/reference/android/graphics/Bitmap.Config

It would seem RGB_565 could be the solution.

You can use this (untested) code to create a mutable bitmap with different configuration:

Sub Create565Bitmap(Width As Int, Height As Int) As Bitmap
 Dim jo As JavaObject
 Return jo.InitializeStatic("android.graphics.Bitmap").RunMethod("createBitmap", Array(Width, Height, "RGB_565"))
End Sub

Erel, you are the best !

It works perfectly, and the printer no longer gets into error

Thank you.
