Adding image assets to your Roku Channel allow your to make the channel your own! Using the Zype Platform and Zype API, you will be able to change the majority of images on the fly without having to republish your app. However, there are a few images that need to be bundled during installation because they make up your application icon set. These images live on the Roku Channel store. This tutorial will describe the images that need to be bundled, the images that can be updated via the Zype Platform, and the specs for both.
Assets that can only be configured during publication:
Example assets are included in our Roku SDK and need to be packaged with the Roku Channel are because they make up your application icon set. They do not get loaded via a call to the Zype API:
Image Home (Center Focus Icon) - your large icon. HD is 366 x 210 pixels, SD is 248 x 140 pixels. PNG format.
Image Brand (Side Icon) - your small icon. HD is 108 x 69 pixels, SD is 80 x 46 pixels. PNG format.
Image Splash - the splash screen (what appears while your Roku Channel loads). 640 x 480 pixels. JPG format.
When publishing, you will also need a HD Poster that is a 290 x 218 JPG format and an SD Poster that is a 214 x 144 JPG format. We call that the Image Store in our Zype Roku App.
Assets that can be changed using the Zype Platform and Zype API:
These assets get loaded via a call to the Zype API every time the Roku Channel gets loaded.
