C# - GetData() cannot be natively converted to float[]

[sixstepsaway]

Tested versions

• 4.3.beta2.mono

System information

Windows 10, Forward+

Issue description

In GDScript, you can call

image.get_data().to_float32_array()

which gets the data from the image and returns it as a float array.

In C# there's no native way of converting, so the only way I can do this is I have to have a GDScript on a node and call that, but I can't do that off the main thread, so I can't background thread it.

Any chance of a conversion like GDScript has, somehow?

Steps to reproduce

Get an image. Run image.GetData(). Observe the lack of conversion :(

Minimal reproduction project (MRP)

Same as above: Get an image. Run image.GetData(). Observe the lack of conversion :(

This would be something on the C# library side, have you checked if there is a C# equivalent in the standard library there? The equivalent data is just a standard System.Array, try, for example System.BitConverter

There isn't. It returns byte, you can't choose to have it as a float instead, and converting byte to float in C# is... complex.

I mean to convert byte[] to float[], there's no method on Image to get a float[], in GDScript or C#, the difference is that PackedByteArray is a raw array in C#, so the conversion is something that's the responsibility of the C# side, specifically the library

All right, thank you.
