OpenCVMatToNativeBatch

OpenCVMatToNativeBatch

Demonstrates how to take a OpenCV mat and convert it to a Bitmap which is then converted to a Texture2D for use with the NativeBatch. The texture is then shown on screen and can be compared to the same texture that was loaded using the normal DemoFramework methods.

The cv::Mat -> Bitmap routines used here are a very basic proof of concept.

Command line arguments':

Argument Description Source
--ActualDpi <arg> ActualDpi [x,y] Override the actual dpi reported by the native window DemoHost
--DensityDpi <arg> DensityDpi <number> Override the density dpi reported by the native window DemoHost
--DisplayId <arg> DisplayId <number> DemoHost
--LogExtensions Output the extensions to the log DemoHost
--LogLayers Output the layers to the log DemoHost
--LogSurfaceFormats Output the supported surface formats to the log DemoHost
--VkApiDump Enable the VK_LAYER_LUNARG_api_dump layer. DemoHost
--VkPhysicalDevice <arg> Set the physical device index. DemoHost
--VkPresentMode <arg> Override the present mode with the supplied value. Known values: VK_PRESENT_MODE_IMMEDIATE_KHR (0), VK_PRESENT_MODE_MAILBOX_KHR (1), VK_PRESENT_MODE_FIFO_KHR (2), VK_PRESENT_MODE_FIFO_RELAXED_KHR (3), VK_PRESENT_MODE_SHARED_DEMAND_REFRESH_KHR (1000111000), VK_PRESENT_MODE_SHARED_CONTINUOUS_REFRESH_KHR (1000111001) DemoHost
--VkScreenshot <arg> Enable/disable screenshot support (defaults to enabled) DemoHost
--VkValidate <arg> Enable/disable the VK_LAYER_LUNARG_standard_validation layer. DemoHost
--Window <arg> Window mode [left,top,width,height] DemoHost
