Enumeration Type Documentation

◆ AlignType

enum te::map::AlignType

This enum contains values to control the alignment of components (like Canvas and MapDisplay).

Enumerator
Top	Top.
Center	Center.
Bottom	Bottom.
Left	Left.
Right	Right.

Definition at line 125 of file Enums.h.

◆ ChartType

enum te::map::ChartType

The chart types.

Enumerator
Pie	A pie chart.
Bar	A bar chart.

Definition at line 164 of file Enums.h.

◆ CompositionMode

enum te::map::CompositionMode

The composition mode used to render the canvas.

Enumerator
SourceOver	This is the default mode. The alpha of the source is used to blend the pixel on top of the destination.
DestinationOver	The alpha of the destination is used to blend it on top of the source pixels.
Clear	The pixels in the destination are cleared (set to fully transparent) independent of the source.
Source	The output is the source pixel. (This means a basic copy operation and is identical to SourceOver when the source pixel is opaque).
Destination	The output is the destination pixel. This means that the blending has no effect.
SourceIn	The output is the source, where the alpha is reduced by that of the destination.
DestinationIn	The output is the destination, where the alpha is reduced by that of the source.
SourceOut	The output is the source, where the alpha is reduced by the inverse of destination.
DestinationOut	The output is the destination, where the alpha is reduced by the inverse of the source.
SourceAtop	The source pixel is blended on top of the destination, with the alpha of the source pixel reduced by the alpha of the destination pixel.
DestinationAtop	The destination pixel is blended on top of the source, with the alpha of the destination pixel is reduced by the alpha of the destination pixel.
Xor	The source, whose alpha is reduced with the inverse of the destination alpha, is merged with the destination, whose alpha is reduced by the inverse of the source alpha.
Plus	Both the alpha and color of the source and destination pixels are added together.
Multiply	The output is the source color multiplied by the destination. Multiplying a color with white leaves the color unchanged, while multiplying a color with black produces black.
Screen	The source and destination colors are inverted and then multiplied. Screening a color with white produces white, whereas screening a color with black leaves the color unchanged.
Overlay	Multiplies or screens the colors depending on the destination color. The destination color is mixed with the source color to reflect the lightness or darkness of the destination.
Darken	The darker of the source and destination colors is selected.
Lighten	The lighter of the source and destination colors is selected.
ColorDodge	The destination color is brightened to reflect the source color. A black source color leaves the destination color unchanged.
ColorBurn	The destination color is darkened to reflect the source color. A white source color leaves the destination color unchanged.
HardLight	Multiplies or screens the colors depending on the source color. A light source color will lighten the destination color, whereas a dark source color will darken the destination color.
SoftLight	Darkens or lightens the colors depending on the source color. Similar to CompositionMode_HardLight.
Difference	Subtracts the darker of the colors from the lighter. Painting with white inverts the destination color, whereas painting with black leaves the destination color unchanged.
Exclusion	Similar to CompositionMode_Difference, but with a lower contrast. Painting with white inverts the destination color, whereas painting with black leaves the destination color unchanged.
