I’ve started a couple posts lately, only to find them more complex than expected. So to get myself back on the board, tonight you get a pretty simple one, based on an error one of my colleagues encountered recently. Suppose we…
Today I get to give you a sneak peak into a feature that's not yet officially present, but you'll find if you know where to look: XQuery-level integration with ImageMagick! In this post I demonstrate automatically scaling down large images for CurioVault.com.
