Colour Finding
|
|
==============
|
|
|
|
Finding colours on the screen is quite simple. Simba offers methods like
|
|
``FindColor`` to locate colours on the screen.
|
|
|
|
These methods are usually composed out of several (but not always all)
|
|
components:
|
|
* The colour to search for.
|
|
* An area to search in, defined by *x1*, *y1*, *x2*, *y2*.
|
|
* Tolerance applied to the colour matching. With a maximum tolerance all
|
|
colours are matched.
|
|
* Spiral. A spiral defines a point where the search will start from.
|
|
This is particulary useful if you want the first result near specific
|
|
coordinates.
|
|
* AreaSize. The size the box of colours should be. Usually this is not
|
|
adjustable.
|
|
* A single point in *x*, *y* can be returned, or a set or points called
|
|
a *TPointArray*.
|
|
|
|
.. note::
|
|
Other techniques exist, which involve relative point distance from one point
|
|
to another; these are found in the :ref:`_scriptref_DTM` section.
|
|
|
|
.. note::
|
|
|
|
Although the documentation uses the ``English`` spelling of
|
|
``colour``; the code for compatibility sake uses ``color``, without the u.

Colour Finding Methods
|
|
----------------------
|
|
|
|
A list of all colour finding methods in Simba.
|
|
|
|
SimilarColors
|
|
~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function SimilarColors(C1, C2, Tolerance: Integer): Boolean;
|
|
|
|
SimilarColors returns true if the two passed colours are *similar* given the
|
|
passed tolerance.
|
|
|
|
FindColor
|
|
~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColor(var x, y: Integer; col, x1, y1, x2, y2: Integer):
|
|
Boolean;
|
|
|
|
|
|
FindColor returns true if the exact colour given (col) is found in the box
|
|
defined by *x1*, *y1*, *x2*, *y2*.
|
|
The point is returned in *x* and *y*.
|
|
It searches from the top left to the bottom right and will stop
|
|
after matching a point.
|
|
|
|
FindColorTolerance
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColorTolerance(var x, y: Integer; col, x1, y1, x2, y2, tol:
|
|
Integer): Boolean;
|
|
|
|
FindColorTolerance returns true if a colour within the given tolerance range
|
|
*tol* of the given colour *col* is found in the box defined by *x1*, *y1*,
|
|
*x2*, *y2*.
|
|
Only the first point is returned in *x* and *y*.
|
|
Whether or not a colour is within the tolerance range is determined by the
|
|
:ref:`scriptref_CTS` mode. It searches from the top left to the bottom right
|
|
and will stop after matching a point.
|
|
|
|
FindColors
|
|
~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColors(var pts: TPointArray; col, x1, y1, x2, y2): Boolean;
|
|
|
|
FindColors returns a list of all points that match the colour *col* in an area
|
|
defined by *x1*, *y1*, *x2*, *y2*. It returns true if one or more points have
|
|
been found.
|
|
|
|
FindColorsTolerance
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColorsTolerance(var pts: TPointArray; col, x1, y1, x2, y2,
|
|
tol: Integer): Boolean;
|
|
|
|
FindColorsTolerance returns true if at least one point was found.
|
|
A point is found if it is within the given tolerance range *tol*
|
|
of the given colour *col* and inside the box defined by *x1*, *y1*, *x2*, *y2*.
|
|
Whether or not a color is within the tolerance range is determined by the
|
|
:ref:`scriptref_CTS` mode.
|
|
It searches from the top left to the bottom right and will find all
|
|
matching points in the area.
|
|
|
|
FindColorSpiral
|
|
~~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColorSpiral(var x, y: Integer; color, xs,ys,xe,ye:Integer):
|
|
Boolean;
|
|
|
|
Same as FindColor, but starts searching from *x*, *y*.
|
|
|
|
FindColorSpiralTolerance
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColorToleranceSpiral(var x, y: Integer; color,
|
|
xs,ys,xe,ye,tolerance:Integer): Boolean
|
|
|
|
Same as FindColorTolerance, but starts searching from *x*, *y*.
|
|
|
|
FindColorsSpiralTolerance
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FindColorsSpiralTolerance(x, y: Integer;
|
|
var pts: TPointArray; col, x1, y1, x2, y2, tol: Integer): Boolean;
|
|
|
|
Same as FindColorsTolerance, but starts searching from *x*, *y*.
|
|
|

Colour tolerance
|
|
----------------
|
|
|
|
Simba contains several algorithms for determining if two colours are equal
|
|
given a tolerance. There are three algorithms:
