"Drawing on canvas - how computers read pixels" — Mariko Kosaka
Abstract:
Drawing an image on-screen is a fundamental part of making digital graphics. There are so many tools and libraries such as Photoshop and ImageMagic available to us to perform various tasks. We draw, crop, apply filters, and compress images all the time. But what exactly is happening when we use those tools? What do those different settings and parameters mean? Do we need elaborate tools or can we roll up our own? In this talk, Mariko will introduce core concepts in digital imaging and image processing. The talk will explore what is happening on a pixel-level when you draw charts in your screen or apply filters to an image. Once you understand what a pixel is and how to manipulate it, you can make a smart and confident choice in your rendering method and formatting.
