rendertarget_reconfigure(3) Arcan Lua API rendertarget_reconfigure(3) NAME rendertarget_reconfigure - Change the output density or processing flags of a rendertarget SYNOPSIS nil rendertarget_reconfigure( vid:rtgt, float:hppcm, float:vppcm ) DESCRIPTION Two major properties of a rendertarget are the intended output density and the targetted colour space. For vectorized assets that are sized in physical units e.g. pt (1/72th of an inch) like with render_text, the engine needs knowledge of the target output before drawing. By default, this is some display-dependent initial size, accessible through the global constants HPPCM and VPPCM , or 38.4 when those cannot be found. When targeting a display, locally or remote, that has a different density it is typically advised to update the render- target pipeline that gets mapped to that output using this function. When- ever an asset gets created or attached to a rendertarget, it will be rerastered to match the density of the rendertarget. NOTES 1 For HDR composition and rendering, you typically need to provide further metadata about light levels and so on. This can be set on the rtgt using image_metadata .
