✨ NAME ✨

EMF::EMRSETWINDOWEXTEX — the EMF Set Window Extent (ex) record, bestie 💖

It's part of libemf, section 3 of the manual, and it's here to tell your metafile how big the logical window is. Iconic, honestly.

🦋 SYNOPSIS 🦋

#include <libemf.h>

So the tea is: this class inherits from EMF::METARECORD, and also from EMRSETVIEWPORTEXTEX. She's got a whole family tree. Family reunion energy. 🌈

👑 Public Member Functions 👑

  • EMRSETWINDOWEXTEX (INT cx, INT cy) — build one from a width and a height, go off
  • EMRSETWINDOWEXTEX (DATASTREAM &ds) — build one by reading it out of a datastream
  • bool serialize (DATASTREAM ds) — write this record out to a datastream
  • int size (void) const — how many bytes this record takes up
  • void execute (METAFILEDEVICECONTEXT *source, HDC dc) const — actually run this record against a device context

🧚 Public Member Functions inherited from EMF::METARECORD

  • virtual ~METARECORD () — the destructor she got from her parent, no notes 💅

💜 Detailed Description 💜

EMF Set Window Extent (ex). That's the whole vibe. ✨

Okay so the window extents define the scale of the logical coordinates. That's the main character mechanic right there. For example, if your XY plot goes from [-10,-10] to [10,10], then the window extents are [20,20]. Math ate that. 🔥

🎀 Constructor & Destructor Documentation 🎀

EMF::EMRSETWINDOWEXTEX::EMRSETWINDOWEXTEX (INT cx, INT cy) [inline]

Make a brand new one with the extents you want, periodt.

Parameters

  • cx — width of window in logical coordinates.
  • cy — height of window in logical coordinates.

EMF::EMRSETWINDOWEXTEX::EMRSETWINDOWEXTEX (DATASTREAM & ds) [inline]

Construct a SetWindowExtEx record from the input stream. Reading it in, not writing it out — important distinction, iykyk. 📖

Parameters

  • ds — Metafile datastream.

🌸 Member Function Documentation 🌸

void EMF::EMRSETWINDOWEXTEX::execute (METAFILEDEVICECONTEXT * source, HDC dc) const [inline], [virtual]

Execute this record in the context of the given device context. She's doing her thing live on stage. 🎤

Parameters

  • source — the device context from which this record is taken.
  • dc — device context for execute.

Implements EMF::METARECORD.

bool EMF::EMRSETWINDOWEXTEX::serialize (DATASTREAM ds) [inline], [virtual]

Serializing. That's it, that's the function. ✍️

Parameters

  • ds — Metafile datastream.

Implements EMF::METARECORD.

int EMF::EMRSETWINDOWEXTEX::size (void) const [inline], [virtual]

Internally computed size of this record. She knows her own measurements, no external validation needed. 💅

Implements EMF::METARECORD.
