<short>Contains routines and types used when drawing graphics.</short>
|
|
<descr>
|
|
<p>
|
|
<var>GraphUtil.pp</var> contains routines and types used when drawing
|
|
graphics. They focus primarily on converting colors and drawing gradients,
|
|
scroll bars, and arrows.
|
|
</p>
|
|
<p>
|
|
It includes routines used to convert between both the HSL (hue, saturation,
|
|
lightness) and HSV (hue, saturation, brightness value) alternative
|
|
representations of the RGB color model.
|
|
</p>
|
|
<p>
|
|
HSV models the way different colors mix together, with the saturation
|
|
dimension resembling various tints of brightly colored paint, and the value
|
|
dimension resembling the mixture of those paints with varying amounts of
|
|
black or white paint.
|
|
</p>
|
|
<p>
|
|
HSL places saturated colors around a circle with a lightness value of 0.5,
|
|
where a lightness value of 0 or 1 is fully black or white (respectively).
|
|
</p>
|
|
<p>
|
|
GraphUtil is used in the Lazarus IDE, in LCL WidgetSet components, and
|
|
optional Lazarus components like FPReport, SynEdit, and TAChart.

<descr>
|
|
<p>
|
|
<var>BitmapGrayscale</var> is a procedure used to convert the specified
|
|
bitmap image to a grayscale image. It calculates the weighted average of the
|
|
RGB (Red, Green, Blue) color components of each pixel in the bitmap and
|
|
assigns it to each color component. Weighting is done by multiplication of
|
|
the RGB values with the corresponding filter factors in the RedFilter,
|
|
GreenFilter and BlueFilter arguments. The end result is an image where the
|
|
original colors are converted to various shades of gray.
|
|
</p>
|
|
<p>
|
|
<var>ABitmap</var> is the <var>TCustomBitmap</var> instance with the original
|
|
image data.
|
|
</p>
|
|
<p>
|
|
<var>RedFilter</var>, <var>GreenFilter</var> and <var>BlueFilter</var> are
|
|
multipliers (data type: single) for the red, green, blue color components of
|
|
each pixel when the average value of the three color components is
|
|
calculated. Usually these factors are between 0.0 and 1.0 and are selected to
|
|
suppress or enhance the contribution of the corresponding color channel to
|
|
the overall grayscale value. The combination 0.30, 0.59, 0.11 for the red,
|
|
green and blue components, respectively, is often chosen because it matches
|
|
the sensitivity of the human eye and thus results in a visual brightness
|
|
impression like in the original color image.

BitmapGrayscale(Image1.Picture.Bitmap, 1.00, 0.00, 0.00); // Red filter
|
|
BitmapGrayscale(Image1.Picture.Bitmap, 0.00, 1.00, 0.00); // Green filter
|
|
BitmapGrayscale(Image1.Picture.Bitmap, 0.00, 0.00, 1.00); // Blue filter
|
|
BitmapGrayscale(Image1.Picture.Bitmap, 0.00, 0.50, 0.50); // Cyan filter
|
|
BitmapGrayscale(Image1.Picture.Bitmap, 0.50, 0.00, 0.50); // Magenta filter
|
|
BitmapGrayscale(Image1.Picture.Bitmap, 0.50, 0.50, 0.00); // Yellow filter

Draws a line with an arrow at the specified location on a canvas.

|
<descr>
|
|
<p>
|
|
<var>DrawArrow</var> is an overloaded procedure used to draw a line between
|
|
the specified points with an arrow at the ending point.
|
|
</p>
|
|
<p>
|
|
Overloaded variants of the routine allow the arguments to be specified using
|
|
various types. The variant with Direction, Location, Size, and ArrowType
|
|
arguments can draw a line with an arrow head in horizontal or vertical
|
|
directions only. The variant with the ArrowAngleRad argument allows the slope
|
|
for sides on the arrow head to be specified as a number of radians.
|
|
</p>
|
|
<p>
|
|
<var>Direction</var> is a <var>TScrollDirection</var> enumeration value, and
|
|
indicates the direction for the line and the arrow head. Allowed values
|
|
include: sdLeft, sdRight, sdUp, or sdDown.
|
|
</p>
|
|
<p>
|
|
<var>Location</var> is a <var>TPoint</var> instance which contains the
|
|
coordinates for the line starting point. This is the same as the
|
|
<var>p1</var> argument in an overloaded variant. <var>p2</var> is the ending
|
|
point for the line and the position where the tip of the arrow head is drawn.
|
|
</p>
|
|
<p>
|
|
<var>Size</var> contains the length of the line in pixels. It is used to
|
|
calculate both the ending point for the line starting at Location, and the
|
|
position where the tip of the arrow head is drawn.
|
|
</p>
|
|
<p>
|
|
<var>ArrowType</var> is a <var>TArrowType</var> enumeration value, and
|
|
indicates the drawing style used for the arrow head. atSolid causes the arrow
|
|
head to be drawn as a filled triangular polygon. atArrows causes two inclined
|
|
lines to be draw at the tip of the arrow head using the slope angle specified
|
|
in ArrowAngleRad.
|
|
</p>
|
|
<p>
|
|
<var>ArrowAngleRad</var> is a floating point value with the number of radians
|
|
for the slope on the sides of the arrow head. The default value for the
|
|
argument is defined in the NiceArrowAngle constant, and causes a 45 degree
|
|
angle to be used to draw the inclined sides on arrow head. Use
|
|
<b><angle>*pi/180</b> to convert an angle in degrees to radians.

|
|
<var>FloodFill</var> is a procedure which implements a simple
|
|
first-in-first-out circular buffer (queue) for flood-filling contiguous
|
|
voxels. This algorithm avoids stack problems associated simple recursive
|
|
algorithms described in the discussion at <url
|
|
href="http://steve.hollasch.net/cgindex/polygons/floodfill.html"/>. Please
|
|
note that the routine is slow because of its use of <var>Canvas.Pixels</var>.
