Detailed Description

create a raw frame for confirmation UI dialog

Many rendering code borrowed from the following source https://android.googlesource.com/trusty/app/confirmationui/+/0429cc7/src

Member Typedef Documentation

◆ LabelConfMsg

using cuttlefish::confui::ConfUiRendererImpl::LabelConfMsg = teeui::LabelBody

Constructor & Destructor Documentation

◆ ConfUiRendererImpl()

cuttlefish::confui::ConfUiRendererImpl::ConfUiRendererImpl ( std::uint32_t  display,
const std::string &  confirmation_msg,
const std::string &  locale,
bool  inverted,
bool  magnified 
)
private

device configuration

ctx_{# of pixels in 1 mm, # of pixels per 1 density independent pixels}

The numbers are, however, to fit for the host webRTC local/remote clients in general, not necessarily the supposedly guest device (e.g. Auto, phone, etc)

In general, for a normal PC, roughly ctx_(6.45211, 400.0/412.0) is a good combination for the default DPI, 320. If we want to see the impact of the change in the guest DPI, we could adjust the combination above proportionally

this does not repaint from the scratch all the time

It does repaint its frame buffer only when w/h of current display has changed
