COMP6023 DCOM1 Class 30 Transparency & PNG

We looked at transparency and the PNG format.

COMP6021 Class 32 Tutorial

Today's class was a tutorial. We looked at dithering questions from the set of sample questions.

Working out the weighted average of the RGB values is easy enough. But generating a dithering pattern from a patent and a target simulated colour, is a bit trickier.

Students should expect a dithering question on the summer exam.

COMP6023 DCOM1b Classes 31 & 32

Students worked on the assignments. I am keen for students to finish soon. There is no reason to delay. Students already have all the information they need to complete all the assignments.

Students did a dithering exercise using Photoshop.

COMP6023 SEO Example

Thanks to a problem with my roof I recently found this ideal example of a website that is in need of some SEO. The whole site is a collection of images.
