Dumping binary context of 2D array texture only works for selected layer.

[reduz]

Description

Inspecting an array texture as binary and saving it to a file only saves one layer of the whole texture.

Steps to reproduce

When inspecting an array texture as binary:

This has 24 layers, hence the total size should be 686128*24 = 7990272

Exploring as binary shows the whole thing:

But RMB -> Export to Bytes

Only saves one layer:
332928 save_data.bin

7990272 / 24 = 332928

Either the whole texture should be saved, or an option to save either the whole texture or the current layers should be offered.

I found this error while trying to workaround #3148, by the way.

Environment

• RenderDoc version: 1.28
• Operating System: Ubuntu
• Graphics API: Vulkan
• GPU: GTX 1650

When viewing a texture's bytes in the buffer viewer it is intentional that only one subresource is displayed at a time, since the physical layout of subresources is not necessarily defined or consistent. That commit clarifies this (and disables the byte offset/length fields as those are not supported for textures).

If you want to save the whole texture to a file without conversion, you can save to dds which supports all texture formats natively and has a defined layout. You could also use a python extension to save to a custom format if you want the raw bits with no headers and custom alignment/ordering.
