Not able to open a 40MB TIF


Recommended Posts

What is the pixel resolution? That image is probably at least 3800 x 4600 pixels, correct?

Paint.NET converts everything to 32-bit internally. That means that a 1-bit black & white image takes up at least 32x the memory that it otherwise would.

Sorry, but Paint.NET always converts to 32-bit internally, due to the way the application is architected. Because of this, the enormous image you're trying to load would require about 8 GB of memory! :shock:

29632 * 23951 * 4 * 3 = 8,516,592,384

8,516,592,384 / 1024 / 1024 / 1024 = 7.93 GB (!)

The *4 is for 32-bits per pixel (and there are 8 bits per byte), the *3 is because we require 1 buffer per layer, 1 buffer for composition, and 1 buffer for scratch.
