Assigned to release

• ATPhoto 1.0-alpha1 (Alpha release)

State

ready-for-merge

Motivation

Increasing the Presentation Quality of ATPhotoAlbum. Make it more than just a ATFolder images with another view.

Assumptions

Needs to be discussed...

Proposal

1. Adding DocumentMenus for scales and effects
2. Rewrite the JavaScripts
3. Automatic Scale Selection

Adding DocumentMenus

Nice would be to move scale and effect selection to the DocumentMenu area. Having one for Effects and one for Scales with Effects getting a list of the available slide effects (fade, crossfade, wipe) and the Scales menu showing all the available scales plus automatic (see 3. Automatic Scale Selection for details). This makes them far more easier to use and customize. Options should not show up in the content area.

Rewrite the Transitions JavaScripts

Taking the JS form ATPhoto and make the effects plugable into ATPhoto

Automatic Scale Selection

Try to get the height and width of the parent image-container element to choose automatically the perfect scale which fits the current image-container size best. This function could be invoked on window resize to update the page with a new image scale of the current image.

JavaScript Transition effect available under GNU Lesser General Public License.

Implementation

Needs to be discussed...

Risks

• The Transitions JavaScripts do not seem to work with Opera. All not supported Browsers just swap the images is nice for a Fallback. But Opera should work.
• fschulze mentioned that firefox does move the image while fading. needs to be investigated
• if javascript is disabled it should fallback to a regular photoalbum_view like known in ATFolder
