Method capture_video_frame()

Captures the current pixel information as sent to the monitor of the virtual device.

Usage

RamigaOutput$capture_video_frame(file, ...)

Arguments

file

A path to a png file where to store the captured frame.

...

Ignored

Returns

If file is missing it returns a grDevices::as.raster() object. Otherwise, it will save it as png file to the specified path and returns nothing.

Method capture_audio_buffer()

Capture the audio that is currently on the output buffer. While the emulator is running, audio is continuously generated and stored in a ring buffer. Use this function to collect data in this buffer. It can only be read once and the buffer has a limited capacity.

Usage

RamigaOutput$capture_audio_buffer(file, ...)

Arguments

file

A file path to store the audio (RIFF wav format).

...

Ignored

Returns

If file is omitted, the audio data is returned as a matrix of numeric values. It returns 2 rows (for both stereo channels). The number of columns correspond with the number of samples available from the buffer. The waveform is scaled between -1 and +1, such that it can be played directly with audio::play().

---

Method print()

Prints basic information about the emulator output.

Usage

RamigaOutput$print(...)

Arguments

...

Ignored

Method clone()

The objects of this class are cloneable with this method.

Usage

RamigaOutput$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
