Stretchy Slideshow V2

Post by rbytes » Sun Apr 28, 2019 4:06 am

I posted Stretchy Slideshow three years ago. It was a test to see how I could use sprite scaling to make dynamic wipes that stretched or shrank images to move from one "slide" to another.

I had a bit of trouble with the math for simultaneously growing one picture while shrinking the next, and vice-versa. Thanks to Henko for showing me a solution. It enables me to add 12 new wipes. There are four that look a bit like page turns in four directions, four that start images in a corner and grow them to full screen, and four that start images on midsides and grow them to fill the screen.

Because there are 19 demo slides, I will post the Stretchy Slideshow folder to Dropbox. It contains the program, a folder called Stretchy that contains the images and a MIDI file for the music background. ... DBy8a?dl=0

You can easily substitute your own slides in the Stretchy folder. They should all be sized at 2048 x 1536 to work properly.

The slideshow works on iPhones as well as iPads, but on iPhones a portion of each image will be cropped at the top and bottom so that they fill the screen horizontally. It would be fairly easy to reduce the scale if you would rather see the complete images with empty space on each side.
