Render as image without a file?

[soulflyman]

Hi is there already a possibility to render printer code as an image but keep the image in the memory and don't write it to a file.
This would allow me to save the data into a database instead on the file system.
Currently, I render the code, then it gets saved into a file, I then read the file and write the content to the database.

Eliminating the temporary file would be more efficient.

The current image renderer doesn't support that but it can be added. I think adding a callback as a second argument to the image renderer could do the trick, then you would get a callback with bytes instead of writing to file.

On another note, it's pretty common to just store a url to a file in the database vs storing the image file content.

We have overhauled the rendering system to allow for this.
