Detailed Description

Typedef Documentation

using Gsk::Corner = typedef Corner_Wrapper::Corner

Corner enumerators are scoped by the wrapper class and can be implicitly converted to int.

Enumeration Type Documentation

enum Gsk::BlendMode

strong

The blend modes available for render nodes.

The implementation of each blend mode is deferred to the rendering pipeline.

See https://www.w3.org/TR/compositing-1/#blending for more information on blending and blend modes.

Since gtkmm 4.20:

Enumerator
DEFAULT	The default blend mode, which specifies no blending.
MULTIPLY	The source color is multiplied by the destination and replaces the destination.
SCREEN	Multiplies the complements of the destination and source color values, then complements the result.
OVERLAY	Multiplies or screens the colors, depending on the destination color value. This is the inverse of hard-list.
DARKEN	Selects the darker of the destination and source colors.
LIGHTEN	Selects the lighter of the destination and source colors.
COLOR_DODGE	Brightens the destination color to reflect the source color.
COLOR_BURN	Darkens the destination color to reflect the source color.
HARD_LIGHT	Multiplies or screens the colors, depending on the source color value.
SOFT_LIGHT	Darkens or lightens the colors, depending on the source color value.
DIFFERENCE	Subtracts the darker of the two constituent colors from the lighter color.
EXCLUSION	Produces an effect similar to that of the difference mode but lower in contrast.
COLOR	Creates a color with the hue and saturation of the source color and the luminosity of the destination color.
HUE	Creates a color with the hue of the source color and the saturation and luminosity of the destination color.
SATURATION	Creates a color with the saturation of the source color and the hue and luminosity of the destination color.
LUMINOSITY	Creates a color with the luminosity of the source color and the hue and saturation of the destination color.

enum Gsk::Transform::Category

strong

The categories of matrices relevant for GSK and GTK.

Note that any category includes matrices of all later categories. So if you want to for example check if a matrix is a 2D matrix, category >= GSK_TRANSFORM_CATEGORY_2D is the way to do this.

Also keep in mind that rounding errors may cause matrices to not conform to their categories. Otherwise, matrix operations done via multiplication will not worsen categories. So for the matrix multiplication C = A * B, category(C) = MIN (category(A), category(B)).

Since gtkmm 4.20:

Enumerator
UNKNOWN
ANY
CAT_3D
CAT_2D
CAT_2D_AFFINE
CAT_2D_TRANSLATE
IDENTITY

enum Gsk::Corner_Wrapper::Corner

The corner indices used by Gsk::RoundedRect.

Since gtkmm 4.20:

Enumerator
TOP_LEFT	The top left corner.
TOP_RIGHT	The top right corner.
BOTTOM_RIGHT	The bottom right corner.
BOTTOM_LEFT	The bottom left corner.

enum Gsk::FillRule

strong

Specifies how paths are filled.

Whether or not a point is included in the fill is determined by taking a ray from that point to infinity and looking at intersections with the path. The ray can be in any direction, as long as it doesn't pass through the end point of a segment or have a tricky intersection such as intersecting tangent to the path.

(Note that filling is not actually implemented in this way. This is just a description of the rule that is applied.)

New entries may be added in future versions.

Since gtkmm 4.20:

Enumerator
WINDING	If the path crosses the ray from left-to-right, counts +1. If the path crosses the ray from right to left, counts -1. (Left and right are determined from the perspective of looking along the ray from the starting point.) If the total count is non-zero, the point will be filled.
EVEN_ODD	Counts the total number of intersections, without regard to the orientation of the contour. If the total number of intersections is odd, the point will be filled.

enum Gsk::Isolation

strong

These flags describe the types of isolations possible with a Gsk::IsolationNode.

More isolation options may be added in the future.

Since gtkmm 4.22:

Bitwise operators:

Isolation operator|(Isolation, Isolation)
Isolation operator&(Isolation, Isolation)
Isolation operator^(Isolation, Isolation)
Isolation operator~(Isolation)
Isolation& operator|=(Isolation&, Isolation)
Isolation& operator&=(Isolation&, Isolation)
Isolation& operator^=(Isolation&, Isolation)

Enumerator
NONE
BACKGROUND	If the background should be made available. If the background is not available, future operations will be rendered to a transparent background and added to the existing background later.
COPY_PASTE	If copies should be available to paste nodes. If copies are not available, paste nodes can only paste from copies that are made inside the isolated contents.
ALL

enum Gsk::MaskMode

strong

The mask modes available for mask nodes.

Since gtkmm 4.20:

Enumerator
ALPHA	Use the alpha channel of the mask.
INVERTED_ALPHA	Use the inverted alpha channel of the mask.
LUMINANCE	Use the luminance of the mask, multiplied by mask alpha.
INVERTED_LUMINANCE	Use the inverted luminance of the mask, multiplied by mask alpha.

enum Gsk::PorterDuff

strong

Enumerator
SOURCE
DEST
SOURCE_OVER_DEST
DEST_OVER_SOURCE
SOURCE_IN_DEST
DEST_IN_SOURCE
SOURCE_OUT_DEST
DEST_OUT_SOURCE
SOURCE_ATOP_DEST
DEST_ATOP_SOURCE
XOR
CLEAR

enum Gsk::ScalingFilter

strong

The filters used when scaling texture data.

The actual implementation of each filter is deferred to the rendering pipeline.

Since gtkmm 4.20:

Enumerator
LINEAR	Linear interpolation filter.
NEAREST	Nearest neighbor interpolation filter.
TRILINEAR	Linear interpolation along each axis, plus mipmap generation, with linear interpolation along the mipmap levels.
