This class is used to control the shape and color of the drawing operations performed by a PNMPainter object.
Normally, you don't create a PNMBrush directly; instead, use one of the static PNMBrush.make_*() methods provided here.
A PNMBrush is used to draw the border of a polygon or rectangle, as well as for filling its interior. When it is used to draw a border, the brush is "smeared" over the border; when it is used to fill the interior, it is tiled through the interior.

int getRefCount | ( | ) | [inherited] |
Returns the current reference count.
static PNMBrush makeImage | ( | PNMImage const | image, |
double | xc, | ||
double | yc, | ||
BrushEffect | effect | ||
) | [static] |
Returns a new brush that paints with the indicated image.
xc and yc indicate the pixel in the center of the brush.
The brush makes a copy of the image; it is safe to deallocate or modify the image after making this call.
Returns a new brush that paints with the indicated image.
xc and yc indicate the pixel in the center of the brush.
The brush makes a copy of the image; it is safe to deallocate or modify the image after making this call.
Returns a new brush that paints a single pixel of the indicated color on a border, or paints a solid color in an interior.
static PNMBrush makePixel | ( | VBase4D const | color, |
BrushEffect | effect | ||
) | [static] |
Returns a new brush that paints a single pixel of the indicated color on a border, or paints a solid color in an interior.
static PNMBrush makeSpot | ( | VBase4D const | color, |
double | radius, | ||
bool | fuzzy, | ||
BrushEffect | effect | ||
) | [static] |
Returns a new brush that paints a spot of the indicated color and radius.
If fuzzy is true, the spot is fuzzy; otherwise, it is hard-edged.
Returns a new brush that paints a spot of the indicated color and radius.
If fuzzy is true, the spot is fuzzy; otherwise, it is hard-edged.
static PNMBrush makeTransparent | ( | ) | [static] |
Returns a new brush that does not paint anything.
Can be used as either a pen or a fill brush to make borderless or unfilled shapes, respectively.
ref | ( | ) | [inherited] |
Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
bool testRefCountIntegrity | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't completely bogus.
Returns true if ok, false otherwise.
Reimplemented in NodeReferenceCount, CachedTypedWritableReferenceCount, and NodeCachedReferenceCount.
bool testRefCountNonzero | ( | ) | [inherited] |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus.
Returns true if ok, false otherwise.
bool unref | ( | ) | [inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
Reimplemented in GeomVertexArrayFormat, and GeomVertexFormat.
