Struct qt_gui::QColorTransform

#[repr(C)]pub struct QColorTransform { /* fields omitted */ }

QColorTransform is an instantiation of a transformation between color spaces. It can be applied on color and pixels to convert them from one color space to another.

C++ class: QColorTransform.

C++ documentation:

QColorTransform is an instantiation of a transformation between color spaces. It can be applied on color and pixels to convert them from one color space to another.

Setting up a QColorTransform takes some preprocessing, so keeping around QColorTransforms that you need often is recommended, instead of generating them on the fly.

Methods

impl QColorTransform

pub unsafe fn copy_from(
    &self,
    other: impl CastInto<Ref<QColorTransform>>
) -> Ref<QColorTransform>

This is supported on cpp_lib_version="5.14.0" only.

Calls C++ function: QColorTransform& QColorTransform::operator=(const QColorTransform& other).

pub unsafe fn map_uint(&self, argb: c_uint) -> c_uint

This is supported on cpp_lib_version="5.14.0" only.

Applies the color transformation on the QRgb value argb.

Calls C++ function: unsigned int QColorTransform::map(unsigned int argb) const.

C++ documentation:

Applies the color transformation on the QRgb value argb.

The input should be opaque or unpremultiplied.

pub unsafe fn map_q_rgba64(
    &self,
    rgba64: impl CastInto<Ref<QRgba64>>
) -> CppBox<QRgba64>

This is supported on cpp_lib_version="5.14.0" only.

Applies the color transformation on the QRgba64 value rgba64.

Calls C++ function: QRgba64 QColorTransform::map(QRgba64 rgba64) const.

C++ documentation:

Applies the color transformation on the QRgba64 value rgba64.

The input should be opaque or unpremultiplied.

pub unsafe fn map_q_color(
    &self,
    color: impl CastInto<Ref<QColor>>
) -> CppBox<QColor>

This is supported on cpp_lib_version="5.14.0" only.

Applies the color transformation on the QColor value color.

Calls C++ function: QColor QColorTransform::map(const QColor& color) const.

C++ documentation:

Applies the color transformation on the QColor value color.

pub unsafe fn new() -> CppBox<QColorTransform>

This is supported on cpp_lib_version="5.14.0" only.

Calls C++ function: [constructor] void QColorTransform::QColorTransform().

pub unsafe fn new_copy(
    color_transform: impl CastInto<Ref<QColorTransform>>
) -> CppBox<QColorTransform>

This is supported on cpp_lib_version="5.14.0" only.

Calls C++ function: [constructor] void QColorTransform::QColorTransform(const QColorTransform& colorTransform).

pub unsafe fn swap(&self, other: impl CastInto<Ref<QColorTransform>>)

This is supported on cpp_lib_version="5.14.0" only.

Calls C++ function: void QColorTransform::swap(QColorTransform& other).
