Struct ImageSpooler 

pub struct ImageSpooler { /* private fields */ }

A simple ZXPrinter spooler that produces images via DotMatrixGfx trait. Use this type as a substitute for the S generic parameter of ZxPrinterDevice or ZxPrinterBusDevice.

Trait Implementations

impl Clone for ImageSpooler

fn clone(&self) -> ImageSpooler

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageSpooler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ImageSpooler

fn default() -> ImageSpooler

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImageSpooler

where ImageSpooler: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl DotMatrixGfx for ImageSpooler

fn is_spooling(&self) -> bool

Returns true if the printer is currently capturing data. Returns false otherwise.

fn lines_buffered(&self) -> usize

Returns an approximate number of graphic lines already buffered.

fn clear(&mut self)

Clears the buffered image data.

fn write_svg_dot_gfx_lines( &self, description: &str, target: &mut dyn Write, ) -> Result<bool>

Renders already buffered image data as an SVG image written to the provided target. Returns Ok(true) if an image has been rendered. If there was no image data spooled, returns Ok(false).

fn write_gfx_data(&mut self, target: &mut Vec<u8>) -> Option<(u32, u32)>

Renders already buffered image data as a monochrome 8-bit greyscale image data. Returns Some(width, height) if an image has been rendered. If there was no image data spooled, returns None.

fn is_empty(&self) -> bool

Returns true if no image has been buffered. Otherwise returns false

impl Serialize for ImageSpooler

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Spooler for ImageSpooler

fn motor_on(&mut self)

Can be implemented to get the notification that the printing will begin shortly.

fn push_line(&mut self, line: &[u8])

After each printed line this method is being called with a reference to a slice containing information about up to 256 printed dots stored in up to 32 bytes.

fn motor_off(&mut self)

Can be implemented to get the notification that the printing has ended.
