Hello Monks!

I’ve been away from perl (and programming in general) for a looong time — so I’m a bit rusty :-(

I have an SQLite database containing jpg blobs.

I’d like to extract them and then pass each jpg data blob (one at a time) into Image::Epeg to create thumbnails.

Unfortunately, Image::Epeg-new(\$jpg_data); isn’t working. (It works ok when reading from a file, but not from a “data ref”).

What I’d like to avoid is extracting the blob to a scalar, writing that to disk and then opening the file from Epeg. Is it possible to extract into a memory-mapped file (one created in a virtual file system) directly? Or something like that?
