GenoRect Class
The GenoRect class encapsulates a rectangle.
| Property |
Description |
Left |
Get or set the left value of the rectangle. |
Right |
Get or set the right value of the rectangle. |
Top |
Get or set the top value of the rectangle. |
Bottom |
Get or set the bottom value of the rectangle. |
ToString |
Returns a string representing the rectangle. The string
returned includes two points in the format "x1, y1 x2, y2".
Example: 123,456 678,999 |
FormatXY1XY2 |
Similar to the ToString property, however
returns a string ready for HTML/XML/SVG attributes. Optionally, you may
pass a parameter to inflate the rectangle.
Example: x1="123" y1="456" x2="789" y2="999" |
FormatXYWH |
Very similar to FormatXY1XY2, however
returns a width and height instead of x2, y2.
Example: x1="123" y1="456" width="666" height="543" |
Usage:
Here is an example to use the GenoRect object.
Set rc = i.Position.boundary_rect
Report.WriteBr rc ' Write the default value (implicitly calling ToString)
Report.WriteBr rc.FormatXY1XY2
Report.WriteBr rc.FormatXY1XY2(-10) ' Shrink the rectangle by 10 units on each side
rc.Left = rc.Left + 1 ' Move the left edge by one unit
Report.WriteBr rc.FormatXYWH
Report.WriteBr rc.FormatXYWH(+5) ' Inflate the rectangle by 5 units on each side
Future Improvements:
The methods FormatXY1XY2 and FormatXYWH could have
an extra parameter strFormatOptions to perform additional
formatting:
| strFormatOption |
Meaning |
" |
Put double quotes around the values. This is the default
value anyways
Example: x1="123" y1="456" x2="789" y2="999" |
' |
Put double quotes around the values.
Example: x1='123' y1='456' x2='789' y2='999' |
= |
Don't put any quotes around the values.
Example: x1=123 y1=456 x2=789 y2=999 |
- |
Negate the y-values (Top and Bottom)
Example: x1="123" y1="-456" x2="789" y2="-999" |
, (comma) |
Separate the values with a comma instead of a space.
Example: x1="123",y1="456",x2="789",y2="999" |
Of course, you could make combinations such as
rc.FormatXYWH 10, "-="
This would return a rectangle inflated by 10 units on each site, with the top
and bottom negated and no quotes around the values.
