Technical data of product parameters
The following rules determine which device pixels a painting operation affects.
All references to coordinates and pixels are in device space. A shape is a path to beFI820F 3BDH000031R1
painted with the current color or with an image. Its coordinates are mapped into
device space but not rounded to device pixel boundaries. At this level, curves
have been flattened to sequences of straight lines, and all “insideness” computations have been performed.
Pixel boundaries always fall on integer coordinates in device space. A pixel is aFI820F 3BDH000031R1
square region identified by the location of its corner with minimum horizontal
and vertical coordinates. The region is half-open, meaning that it includes its
lower but not its upper boundaries. More precisely, for any point whose realnumber coordinates are (x, y), let i = floor(x) and j = floor(y). The pixel that contains this point is the one identified as (i, j). The region belonging to that pixel is
defined to be the set of points (x′, y′) such that i ≤ x′ < i + 1 and j ≤ y′ < j + 1.
Like pixels, shapes to be painted by filling and stroking operations are also treated
as half-open regions that include the boundaries along their “floor” sides, but not
along their “ceiling” sides.
A shape is scan-converted by painting any pixel whose square region intersects
the shape, no matter how small the intersection is. This ensures that no shapeFI820F 3BDH000031R1
ever disappears as a result of unfavorable placement relative to the device pixel
grid, as might happen with other possible scan conversion rules. The area covered by painted pixels is always at least as large as the area of the original shape.
This rule applies both to fill operations and to strokes with nonzero width. Zerowidth strokes are done in a device-dependent manner that may include fewer
pixels than the rule impliesNote: Normally, the intersection of two regions is defined as the intersection of their
interiors. However, for purposes of scan conversion, a filling region is considered to
intersect every pixel through which its boundary passes, even if the interior of the
filling region is empty. Thus, for example, a zero-width or zero-height rectangle
paints a line 1 pixel wide.
