Function holoscan::viz::GetSurfaceFormats

Get the supported surface formats.

<a class="reference internal" href="function_modules_2holoviz_2src_2holoviz_2holoviz_8hpp_1a9b6ca550663db0ab06c5f3ba6877dff7.html#modules_2holoviz_2src_2holoviz_2holoviz_8hpp_1a9b6ca550663db0ab06c5f3ba6877dff7" target="_self">viz::Init()</a> has to be called before since the surface formats depend on the window.

If surface_formats is nullptr, then the number of surface formats supported for the current window is returned in surface_format_count. Otherwise, surface_format_count must point to a variable set by the application to the number of elements in the surface_formats array, and on return the variable is overwritten with the number of values actually written to surface_formats. If the value of surface_format_count is less than the number of surface formats supported, at most surface_format_count values will be written,

Parameters

• surface_format_count – number of surface formats available or queried

• surface_formats – either nullptr or a pointer to an array of SurfaceFormat values
