How do I create a software Image from memory?

Windows
1

My plug-in deals with huge bitmaps sprites and with JUCE 8 my editor takes several seconds to create because of the transfer of this data to the GPU.

I would like to be able to load them to the CPU first, like with JUCE 7, then only transfer the extracted frames to the GPU on demand.

I see how I can create an empty software image using SoftwareImageType(), but how can I create one from memory? ImageFileFormat::loadFrom() doesn’t allow specifying the image type, is there another way to load PNG resources directly to a software image?

Thanks
