Detailed Description

A non-owning image::Image view over a buffer owned by SendspinImageSlot.

Each slot publishes its frames through these: one for the artwork on screen, and optionally a second for the outgoing frame during a cross-fade. A view always names a frame, black to begin with, so LVGL can be given it as a widget source before any artwork exists. Main loop only.

set_showing_artwork()

void esphome::sendspin_::ArtworkImageView::set_showing_artwork ( bool showing_artwork )

inline

Records whether the frame on show is real artwork rather than the black it starts as.

Only changes what the display lambda path draws. The frame itself is left alone, so anything reading the pixels directly (an LVGL widget) keeps drawing the last artwork until it is pointed elsewhere.
