Properties

Colour

#
Colour Colour { get; }
Gets the colour currently selected in this model.

Filter

#
NamedPalette Filter { get; set; }
Gets or sets the source for allowed colours. When not null, this property will limit displayed colours to the defined set of colours in the filter. Assigning a new filter will automatically wipe the display caches. Note that not all models necessarily constrain themselves to a filter, this property is a hint as much as anything.

Format

#
string Format { get; }
Format the current model state.

Icon

#
IIcon Icon { get; }
Gets the icon associated with this model.

Nomen

#
Nomen Nomen { get; }
Gets the description of this model.

Methods

Draw

#
void Draw(Context context, RectangleF bounds, ColourModelVisuals visuals)
Draw this colour model into a graphics context.
Parameters:
context (Context)Context to draw with.
bounds (RectangleF)Target bounds for model.
visuals (ColourModelVisuals)Visual properties.

GetChannels

#
void GetChannels(out UiNumber channel1, out UiNumber channel2, out UiNumber channel3)
Gets the channel values of the current space. The current design of this api does not allow for a varying number of channels. This is potentially a big problem, potentially not. At present the only colour model which requires more than three channels is CMYK.
Parameters:
channel1 (out UiNumber)Properties of first channel.
channel2 (out UiNumber)Properties of second channel.
channel3 (out UiNumber)Properties of third channel.

RespondToMouseDown

#
object RespondToMouseDown(PointF mouse, MouseButtons buttons)
Respond to a mouse down event on this model.
Parameters:
mouse (PointF)Mouse coordinate.
buttons (MouseButtons)Mouse buttons.
Returns: Motion record specific to this model.

RespondToMouseMove

#
void RespondToMouseMove(object motionData, PointF mouse, MouseButtons buttons, Keys keys)
Respond to a mouse move event. These are only relayed when at least one mouse button is down.
Parameters:
motionData (object)Mouse move begin record.
mouse (PointF)New mouse location.
buttons (MouseButtons)Mouse buttons involved.
keys (Keys)Modifier keys involved.

RespondToMouseUp

#
void RespondToMouseUp(object motionData, PointF mouse, MouseButtons buttons, Keys keys)
Respond to a mouse up event.
Parameters:
motionData (object)
mouse (PointF)
buttons (MouseButtons)
keys (Keys)

SetChannels

#
void SetChannels(UiNumber channel1, UiNumber channel2, UiNumber channel3)
Update the colour from channels.
Parameters:
channel1 (UiNumber)First channel.
channel2 (UiNumber)Second channel.
channel3 (UiNumber)Third channel.

SetColour

#
void SetColour(Colour colour)
Change this colour model to reflect a given colour. There is no guarantee that the model colour will be exactly equal to the given colour, there may be both rounding errors as well as gamut constraints.
Parameters:
colour (Colour)Colour to match.
