This is some “Typescript” code for Dall-E. It uses files as well
const response = await openai.createImageEdit(
fs.createReadStream(“sunlit_lounge.png”) as any,
fs.createReadStream(“mask.png”) as any,
“A sunlit indoor lounge area with a pool containing a flamingo”,
1,
“1024x1024”
);
The key thing is that they are using a file system ReadStream (but it is an image). I suspect that if you are not using an openai library to help you, you will have to read the file at your end and feed its content instead of the filename.
