Flipbooks allow the user to move their finger across a hotspot and flip through a sequence of images. They are most often used for 360° views of an object, but are also useful for time-lapse videos, such as a sunset. Flipbooks can also have two optional conditions:
‘inverse’ which draws the last image first and spins backwards through the images, and
‘stop’ which does not loop through all the images, e.g. Flipbook1,inverse,stop .
Hotspot = Flipbook1
|Hotspot options||Inverse, stop|
|Position in Hotspot||Prior to v19 images are aligned to top left of hotspot. From v19 and beyond images are centred in the hotspot.|
|Content resizes to fill hotspot||Aspect fit (If the image is in a different aspect ratio to the hotspot, it will keep the aspect ratio but expand or shrink such that it fits inside the hotspot fully without cropping)|
|Folder Name||Flipbook1 (2, 3 etc)|
|File type(s)||JPG or PNG|
|File name(s)||1.jpg 2.jpg etc up to 180|
|Examples||QA Oomph Walkthough/Oomph_Walkthough/360|
|Transparent background allowed||Yes|
|Draws the last image first and spins backwards through the images|
|Do not loop through all the images, stop at the last/first image when reaching the end|
New Options as of Version 19
As of Oomph v19 the alignment of content within flipbooks will now be center aligned rather that aligned from the top left of the hotspot.
|ppf=n||Specify a "pixels per frame" value. This is a measure of the "speed" of the flipbook and is set as the number of pixels to swipe between images. The default is 60. e.g ppf=80 means the image will change for every 80 pixels of swipe movement.|
|Enable or disable deceleration based momentum when the flipbook is swiped. On by default as of v19, but can be disabled with the option "nomomentum".|
|Specifying this on a regular flipbook makes it behave just like a FlipbookVertical widget|
