BaseRect.h Rectangles have two interpretations: a set of (zero-size) points, and a rectangular area of the plane. Most rectangle operations behave the same no matter what interpretation is being used, but some operations differ: -- Equality tests behave differently. When a rectangle represents an area, all zero-width and zero-height rectangles are equal to each other since they represent the empty area. But when a rectangle represents a set of mathematical points, zero-width and zero-height rectangles can be unequal. -- The union operation can behave differently. When rectangles represent areas, taking the union of a zero-width or zero-height rectangle with another rectangle can just ignore the empty rectangle. But when rectangles represent sets of mathematical points, we may need to extend the latter rectangle to include the points of a zero-width or zero-height rectangle. To ensure that these interpretations are explicitly disambiguated, we deny access to the == and != operators and require use of IsEqualEdges and IsEqualInterior instead. Similarly we provide separate Union and UnionEdges methods. Do not use this class directly. Subclass it, pass that subclass as the Sub parameter, and only use that subclass. 28064 99 %

Blur.cpp 12768 71 %
Blur.h Implementation of a Gaussian blur. A Gaussian blur is good for blurring because, when done independently in the horizontal and vertical directions, it matches the result that would be obtained using a different (rotated) set of axes. This is a "service" class; the constructors set up all the information based on the values. The callers are responsible for creating and managing the backing surface and passing the pointer to the data to the Blur() method. This class does not retain the pointer to the data outside of the Blur() call. A spread N makes each output pixel the maximum value of all source pixels within a square of side length 2N+1 centered on the output pixel. 6238 100 %
BorrowedContext.h This is a helper class that let's you borrow a CGContextRef from a DrawTargetCG. This is used for drawing themed widgets. Callers should check the cg member after constructing the object to see if it succeeded. The DrawTarget should not be used while the context is borrowed. 2203 -

DrawTargetCairo.cpp Clamp r to (0,0) (2^23,2^23) these are to be device coordinates. Returns false if the rectangle is completely out of bounds, true otherwise. This function assumes that it will be called with a rectangle being drawn into a surface with an identity transformation matrix; that is, anything above or to the left of (0,0) will be offscreen. First it checks if the rectangle is entirely beyond CAIRO_COORD_MAX; if so, it can't ever appear on the screen -- false is returned. Then it shifts any rectangles with x/y < 0 so that x and y are = 0, and adjusts the width and height appropriately. For example, a rectangle from (0,-5) with dimensions (5,10) will become a rectangle from (0,0) with dimensions (5,5). If after negative x/y adjustment to 0, either the width or height is negative, then the rectangle is completely offscreen, and nothing is drawn -- false is returned. Finally, if x+width or y+height are greater than CAIRO_COORD_MAX, the width and height are clamped such x+width or y+height are equal to CAIRO_COORD_MAX, and true is returned. 68451 48 %

ImageScaling.h 3059 100 %
ImageScalingSSE2.cpp The functions below use the following system for averaging 4 pixels: The first observation is that a half-adder is implemented as follows: R = S + 2C or in the case of a and b (a ^ b) + ((a & b) << 1); This can be trivially extended to three pixels by observaring that when doing (a ^ b ^ c) as the sum, the carry is simply the bitwise-or of the carries of the individual numbers, since the sum of 3 bits can only ever have a carry of one. We then observe that the average is then ((carry << 1) + sum) >> 1, or, assuming eliminating overflows and underflows, carry + (sum >> 1). We now average our existing sum with the fourth number, so we get: sum2 = (sum + d) >> 1 or (sum >> 1) + (d >> 1). We now observe that our sum has been moved into place relative to the carry, so we can now average with the carry to get the final 4 input average: avg = (sum2 + carry) >> 1; Or to reverse the proof: avg = ((sum >> 1) + carry + d >> 1) >> 1 avg = ((a + b + c) >> 1 + d >> 1) >> 1 avg = ((a + b + c + d) >> 2) An additional fact used in the SSE versions is the concept that we can trivially convert a rounded average to a truncated average: We have: f(a, b) = (a + b + 1) >> 1 And want: g(a, b) = (a + b) >> 1 Observe: ~f(~a, ~b) == ~((~a + ~b + 1) >> 1) == ~((-a - 1 + -b - 1 + 1) >> 1) == ~((-a - 1 + -b) >> 1) == ~((-(a + b) - 1) >> 1) == ~((~(a + b)) >> 1) == (a + b) >> 1 == g(a, b) 12890 76 %

PatternHelpers.h This class is used to allow general pattern creation functions to return any type of pattern via an out-paramater without allocating a pattern instance on the free-store (an instance of this class being created on the stack before passing it in to the creation function). Without this class writing pattern creation functions would be a pain since Pattern objects are not reference counted, making lifetime management of instances created on the free-store and returned from a creation function hazardous. Besides that, in the case that ColorPattern's are expected to be common, it is particularly desirable to avoid the overhead of allocating on the free-store. 5170 86 %

Unless otherwise indicated, methods on this class correspond to methods on BaseRect. The API is currently very bare-bones; it may be extended as needed. Do not use this class directly. Subclass it, pass that subclass as the Sub parameter, and only use that subclass. 11653 85 %
Scale.h Scale an image using a high-quality filter. Synchronously scales an image and writes the output to the destination in 32-bit format. The destination must be pre-allocated by the caller. Returns true if scaling was successful, and false otherwise. Currently, this function is implemented using Skia. If Skia is not enabled when building, calling this function will always return false. IMPLEMTATION NOTES: This API is not currently easily hardware acceleratable. A better API might take a SourceSurface and return a SourceSurface; the Direct2D backend, for example, could simply set a status bit on a copy of the image, and use Direct2D's high-quality scaler at draw time. 1546 -
