PrepareYuiLinearImageRegionV1

Complete bounded Windows vertical slice: on a native cache miss, materialize the exact linear-light result as BGRA8 for the established nearest texture path. This is color-correct on legacy OpenGL contexts where GL_LINEAR would interpolate encoded sRGB bytes.

cpufrontendfrontend.yuifunctionsource-exampleyehoyui

Turn YUI models into a working frontend and its rendering/input adapters.

external PrepareYuiLinearImageRegionV1(yuiRenderImageResource image, yuiRenderImagePresentation presentation, yuiRenderBounds sourceBounds, int destinationWidth, int destinationHeight, text resourceSlot, text source) returns yuiPreparedImageRegionV1

Status: source-declared

Parameters

yuiRenderImageResource image
Supply image as yuiRenderImageResource.
yuiRenderImagePresentation presentation
Supply presentation as yuiRenderImagePresentation.
yuiRenderBounds sourceBounds
Supply source bounds as yuiRenderBounds.
int destinationWidth
Supply destination width as int.
int destinationHeight
Supply destination height as int.
text resourceSlot
Supply resource slot as text.
text source
Supply source as text.

Notes and source

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
