How to make an infinite canvas (at least a very large one)?

Question

Android

I create my own view inside which I draw a bitmap in the onDraw method. The maximum was to create a bitmap the size of the view itself (which is full screen) multiplied by 3, and at the same time the whole application slows down terribly, if you create a bitmap with the size of the view multiplied by 4, openGl error Out of memory pops up in the logs.

Answer 1

We can only advise you to make several bitmaps and load them according to the algorithm.

Answer 2

No way. Different browsers have different limits on the size of the canvas and different reactions or lack thereof: from 3000 to 32767 pixels. In Chrome, this is due to the implementation of the Skia library, link to the bug report: https://code.google.com/p/skia/issues/detail?id=2122
Therefore, displaying large images in the canvas is possible only in the following ways: on a set of canvases or by rendering a part of the image to the canvas.
