DAY 3: Core Image exercises

By Taina — 

On Wednesday, we used script to apply filters and transformations to images. I used some of my artwork in these tests.

An image (wolf) on a background image

For the first time, I’ve saved an image (wolf) as a transparent png file.

coreimagetest_susimetsanpaal

Blurred background and random placement and scaling of the wolf layer

Opacity and amount of rotation have been specified.

coreimagetest_lentaviisusiibluril

Random rotation and placement of several layers of the same image

The scaling and opacity have been specified.
