Slideshow with Controls

Summary

A continuation of the previous slideshow demo but with controls to play, stop, advances, and select slides.

Slideshow demo screenshot

Notes

The images in this demo stack one on top of another from 1 to 9, which is why the top image starts with 9 and plays down to 8, 7, 6, etc.

Simple No Control Slideshow

Summary

Using jQuery to rotate image order in a slidehow instead of using Flash.

This is a work in progress where in future versions, the slideshow will include controls.

Notes

  • The Helper PHP File in the code is the packaged version of Displaying Images from a Directory, which I just demo’d in the previous post.
  • This demo intentionally displays the images slightly off one another’s placement position to show how the ordering works.

Displaying Images from Any Directory

Summary

Use PHP to retrieve image files from a directory and display them without knowing what the image file names are. This builds on the getimagesize() function I demo’d before.

I’m doing this so I can place images in a directory from which I can pull out to display in a slideshow on the home page and maybe the Archives section.

The demo here is only for a more procedural method to do it; for practicality’s sake, I would merge the two steps into one and probably put all of it into a function so I can retrieve an array of image file names just by providing the directory I want the server to look in.

What I Learned

If the web page is not in the same directory of the images, the opendir(), filetype(), and getimagesize() functions take the address of the directory in the parameter with $_SERVER['DOCUMENT_ROOT'] and then the directory from your domain, and not the uri’s (which start with “http://”).

Word It: Flies All Around

Summary

Using Processing to go beyond the Word It medium to learn many functions of the programming language.

This month’s theme is Fly, so I decided to go semi-obvious and spell the word by filling the negative space using images of flies. It sort of reminds me of the Orkin poster where it collects pests with adhesive printed in the Orkin logo pattern on the poster.

Here is my entry on Word It.

Completed build up of flies, spelling out FLY with the negative space.

PHP & Ajax

Summary

The next step of PHP self-teaching after PHP Basics. Learned to use Ajax by using PHP to receive information of an XML file, catalog.xml, and to instruct the display of data onto the original file.

Also added a cookie component so the visitors would not lose their place. Note: the cookie in this experiment expires very quickly so that the experiment can start over without manual deletion of the cookies from the browser.

getimagesize()

Summary

Learning the PHP function getimagesize(). Not only does this function get the size of an image, it gets the info of the file and of Flash files.

I used this function to set the layout of the images and Flash files on my portfolio site.
