sf::StencilComparison
StencilComparison
Enumeration of the stencil test comparisons that can be performed.
Definition StencilMode.hpp:43
sf::StencilComparison::NotEqual
@ NotEqual
The stencil test passes if the new value is strictly unequal to the value in the stencil buffer.
sf::StencilComparison::Less
@ Less
The stencil test passes if the new value is less than the value in the stencil buffer.
sf::StencilComparison::Always
@ Always
The stencil test always passes.
sf::StencilComparison::Never
@ Never
The stencil test never passes.
sf::StencilComparison::GreaterEqual
@ GreaterEqual
The stencil test passes if the new value is greater than or equal to the value in the stencil buffer.
sf::StencilComparison::Greater
@ Greater
The stencil test passes if the new value is greater than the value in the stencil buffer.
sf::StencilComparison::LessEqual
@ LessEqual
The stencil test passes if the new value is less than or equal to the value in the stencil buffer.
sf::StencilComparison::Equal
@ Equal
The stencil test passes if the new value is strictly equal to the value in the stencil buffer.
sf::StencilUpdateOperation
StencilUpdateOperation
Enumeration of the stencil buffer update operations.
Definition StencilMode.hpp:61
sf::StencilUpdateOperation::Keep
@ Keep
If the stencil test passes, the value in the stencil buffer is not modified.
sf::StencilUpdateOperation::Replace
@ Replace
If the stencil test passes, the value in the stencil buffer is set to the new value.
sf::StencilUpdateOperation::Decrement
@ Decrement
If the stencil test passes, the value in the stencil buffer is decremented and if required clamped.
sf::StencilUpdateOperation::Increment
@ Increment
If the stencil test passes, the value in the stencil buffer is incremented and if required clamped.
sf::StencilUpdateOperation::Invert
@ Invert
If the stencil test passes, the value in the stencil buffer is bitwise inverted.
sf::StencilUpdateOperation::Zero
@ Zero
If the stencil test passes, the value in the stencil buffer is set to zero.
sf::StencilMode
Stencil modes for drawing.
Definition StencilMode.hpp:107
sf::StencilMode::operator==
bool operator==(const StencilMode &left, const StencilMode &right)
Overload of the operator==
sf::StencilMode::operator!=
bool operator!=(const StencilMode &left, const StencilMode &right)
Overload of the operator!=
sf::StencilValue
Stencil value type (also used as a mask)
Definition StencilMode.hpp:75
sf::StencilValue::StencilValue
StencilValue(int theValue)
Construct a stencil value from a signed integer.
sf::StencilValue::StencilValue
StencilValue(T)=delete
Disable construction from any other type.
sf::StencilValue::StencilValue
StencilValue(unsigned int theValue)
Construct a stencil value from an unsigned integer.
