defined in header "iswapchain.hpp"

class ISwapchain;

Interface for the Swapchain class. A swapchain contains 1 or more on-screen framebuffers. Right now it can only be used for triple buffering. When an image from a swapchain is presented the front and back buffers are automatically switched around.

Methods

Methods	Description
[getWidth](/dpw105f18/papago-api/wiki/ISwapchain::getWidth)	Returns the width of the swapchain
[getHeight](/dpw105f18/papago-api/wiki/ISwapchain::getHeight)	Returns the height of the swapchain
[getFormat](/dpw105f18/papago-api/wiki/ISwapchain::getFormat)	Returns the format of the swapchain
