Detailed Description

SkIRect holds four 32-bit integer coordinates describing the upper and lower bounds of a rectangle. SkIRect may be created from outer bounds or from position, width, and height. SkIRect describes an area; if its right is less than or equal to its left, or if its bottom is less than or equal to its top, it is considered empty.

Member Function Documentation

◆ adjust()

void SkIRect::adjust	(	int32_t	dL,
		int32_t	dT,
		int32_t	dR,
		int32_t	dB
	)

inline

Adjusts SkIRect by adding dL to fLeft, dT to fTop, dR to fRight, and dB to fBottom.

If dL is positive, narrows SkIRect on the left. If negative, widens it on the left. If dT is positive, shrinks SkIRect on the top. If negative, lengthens it on the top. If dR is positive, narrows SkIRect on the right. If negative, widens it on the right. If dB is positive, shrinks SkIRect on the bottom. If negative, lengthens it on the bottom.

The resulting SkIRect is not checked for validity. Thus, if the resulting SkIRect left is greater than right, the SkIRect will be considered empty. Call sort() after this call if that is not the desired behavior.

Parameters

dL	offset added to fLeft
dT	offset added to fTop
dR	offset added to fRight
dB	offset added to fBottom

Definition at line 446 of file SkRect.h.

                                                                {

    }

◆ bottom()

constexpr int32_t SkIRect::bottom ( ) const

inlineconstexpr

134{ return fBottom; }

◆ contains() [1/3]

}

◆ contains() [3/3]

bool SkIRect::contains	(	int32_t	x,
		int32_t	y
	)		const

inline

Returns true if: fLeft <= x < fRight && fTop <= y < fBottom. Returns false if SkIRect is empty.

Considers input to describe constructed SkIRect: (x, y, x + 1, y + 1) and returns true if constructed area is completely enclosed by SkIRect area.

Parameters

y	test SkIPoint y-coordinate

Returns: true if (x, y) is inside SkIRect

Definition at line 463 of file SkRect.h.

    }

◆ containsNoEmptyCheck()

bool SkIRect::containsNoEmptyCheck ( const SkIRect & r ) const

Returns true if SkIRect contains construction. Asserts if SkIRect is empty or construction is empty, and if SK_DEBUG is defined.

Return is undefined if SkIRect is empty or construction is empty.

Parameters

    }

◆ height()

constexpr int32_t SkIRect::height ( ) const

inlineconstexpr

Returns span on the y-axis. This does not check if SkIRect is sorted, or if result fits in 32-bit signed integer; result may be negative.

If delta.fX is negative, moves SkIRect returned to the left. If delta.fX is positive, moves SkIRect returned to the right. If delta.fY is negative, moves SkIRect returned upward. If delta.fY is positive, moves SkIRect returned downward.

Parameters

delta offset added to SkIRect

    }

◆ offset() [2/2]

void SkIRect::offset	(	int32_t	dx,
		int32_t	dy
	)

inline

Offsets SkIRect by adding dx to fLeft, fRight; and by adding dy to fTop, fBottom.

If dx is negative, moves SkIRect returned to the left. If dx is positive, moves SkIRect returned to the right. If dy is negative, moves SkIRect returned upward. If dy is positive, moves SkIRect returned downward.

Parameters

dx	offset added to fLeft and fRight
dy	offset added to fTop and fBottom

    }

◆ outset()

void SkIRect::outset	(	int32_t	dx,
		int32_t	dy
	)

inline

If dx is positive, makes SkIRect wider. If dx is negative, makes SkIRect narrower. If dy is positive, makes SkIRect taller. If dy is negative, makes SkIRect shorter.

Parameters

127{ return fRight; }

◆ setEmpty()

void SkIRect::setEmpty ( )

inline

Sets SkIRect to (0, 0, 0, 0).

Many other rectangles are empty; if left is equal to or greater than right, or if top is equal to or greater than bottom. Setting all members to zero is a convenience, but does not designate a special empty rectangle.

242{ memset(this, 0, sizeof(*this)); }

Sets SkIRect to (left, top, right, bottom). left and right are not sorted; left is not necessarily less than right. top and bottom are not sorted; top is not necessarily less than bottom.

Parameters

left	stored in fLeft
top	stored in fTop
right	stored in fRight
bottom	stored in fBottom

		int32_t	y,
		int32_t	width,
		int32_t	height
	)

inline

        fRight  = Sk32_sat_add(x, width);
        fBottom = Sk32_sat_add(y, height);
    }

◆ size()

constexpr SkISize SkIRect::size ( ) const

inlineconstexpr

Returns spans on the x-axis and y-axis. This does not check if SkIRect is sorted, or if result fits in 32-bit signed integer; result may be negative.

Returns: SkISize (width, height)

Definition at line 172 of file SkRect.h.

172{ return SkISize::Make(this->width(), this->height()); }

SkISize::Make

static constexpr SkISize Make(int32_t w, int32_t h)

Definition: SkSize.h:20

◆ sort()

void SkIRect::sort ( )

inline

Swaps fLeft and fRight if fLeft is greater than fRight; and swaps fTop and fBottom if fTop is greater than fBottom. Result may be empty, and width() and height() will be zero or positive.

Definition at line 553 of file SkRect.h.

                {
        using std::swap;
        if (fLeft > fRight) {
            swap(fLeft, fRight);
        }
        if (fTop > fBottom) {
            swap(fTop, fBottom);
        }
    }

◆ top()

constexpr int32_t SkIRect::top ( ) const

inlineconstexpr

Returns top edge of SkIRect, if sorted. Call isEmpty() to see if SkIRect may be invalid, and sort() to reverse fTop and fBottom if needed.

Returns: fTop

Definition at line 120 of file SkRect.h.

120{ return fTop; }

◆ topLeft()

constexpr SkIPoint SkIRect::topLeft ( ) const

inlineconstexpr

Definition at line 151 of file SkRect.h.

151{ return {fLeft, fTop}; }

◆ width()

constexpr int32_t SkIRect::width ( ) const

inlineconstexpr

Returns span on the x-axis. This does not check if SkIRect is sorted, or if result fits in 32-bit signed integer; result may be negative.

Returns: fRight minus fLeft

Definition at line 158 of file SkRect.h.

158{ return Sk32_can_overflow_sub(fRight, fLeft); }

◆ width64()

constexpr int64_t SkIRect::width64 ( ) const

inlineconstexpr

Returns span on the x-axis. This does not check if SkIRect is sorted, so the result may be negative. This is safer than calling width() since width() might overflow in its calculation.

Returns: fRight minus fLeft cast to int64_t

Definition at line 180 of file SkRect.h.

180{ return (int64_t)fRight - (int64_t)fLeft; }

◆ x()

constexpr int32_t SkIRect::x ( ) const

inlineconstexpr

Returns left edge of SkIRect, if sorted. Call isEmpty() to see if SkIRect may be invalid, and sort() to reverse fLeft and fRight if needed.

Returns: fLeft

Definition at line 141 of file SkRect.h.

141{ return fLeft; }

◆ y()

constexpr int32_t SkIRect::y ( ) const

inlineconstexpr

Returns top edge of SkIRect, if sorted. Call isEmpty() to see if SkIRect may be invalid, and sort() to reverse fTop and fBottom if needed.

Returns: fTop

Definition at line 148 of file SkRect.h.

148{ return fTop; }
