Can't save as image with unusual extension

[Nakilon]

I would like to save some temporal files with extension .temp but I get No known saver for '1.temp'. (Vips::Error)

Thing like this would be nice:

def write_to_file name, type = nil, opts = {}
  ...
  saver = Vips::vips_foreign_find_save(type || filename)

im.write_to_file "1.temp", "png"

Hello, write_to_file uses the extension to decide what saver to use, so it has to be a known extension.

You can call pngsave directly, for example:

im.pngsave "1.temp"

Would that work?

Yeah seems to work fine. Thanks.
