Save r16 Pixmap?

[SpiderPig]

auto pixmap = CreatePixmap(width, height, TEXTURE_R16);
pixmap->Save("Map.r16");

This fails to save, should it be possible to do?  Or do I need a plugin? 🤔

r16 is not an image format. You can do this:

pixmap->pixels->Save("Map.r16");

BTW, DDS files do support a variety of formats including floats and half-floats. I've been working with these lately and I think these are my preference. There may be some errors in the current DDS saving code for some formats, though.

Okay thanks.  I just want to use the pixmap to apply to a terrain so if the dds option works I'll use that.

The reason I like DDS is because it includes the width and height information, and it specifies the pixel format. A 16-bit heightmap, for example, could consist of half-floats or unsigned shorts. With a raw file there's no way of knowing what format it is.
