Public Functions Documentation

function containsPoint

inline bool videocomposer::OutputInfo::containsPoint (
    int px,
    int py
) const

Check if this output contains a point in global coordinates

---

function findMode

inline const OutputMode * videocomposer::OutputInfo::findMode (
    int w,
    int h,
    double refresh=0.0
) const

Find a specific mode by resolution and optional refresh rate

Parameters:

• w Width
• h Height
• refresh Refresh rate (0 = don't care)

Returns:

Pointer to matching mode, or nullptr if not found

---

function getBounds

inline void videocomposer::OutputInfo::getBounds (
    int & outX,
    int & outY,
    int & outWidth,
    int & outHeight
) const

Get output bounds as a rect

---

function getCurrentMode

inline OutputMode videocomposer::OutputInfo::getCurrentMode () const

Get current mode as OutputMode

---

function getDPI

inline double videocomposer::OutputInfo::getDPI () const

Get DPI (dots per inch) based on physical size

Returns:

DPI value, or 96.0 if physical size unknown

---

function getDisplayName

inline std::string videocomposer::OutputInfo::getDisplayName () const

Get display name for UI (e.g., "Samsung U28E590 (HDMI-A-1)")

---

function getPreferredMode

inline const OutputMode * videocomposer::OutputInfo::getPreferredMode () const

Get the preferred/native mode

Returns:

Pointer to preferred mode, or nullptr if none found
