OCR
|
|
===
|
|
Simba has OCR functions (Optical Text Recognition); these are used to *read* text from an image.
|
|
|
|
It also has a wide variation of text *finding* functions. Both will be covered in
|
|
this article.
|
|
|
|
|
|
Fonts
|
|
-----
|
|
|
|
Fonts are an essential part of the text finding and identifying.
|
|
Now follows a brief explanation of the Font related functions in Simba.
|
|
|
|
All fonts have an unique identifier in the shape of a ``string``.
|
|
If you create or load a new font, they will need to be given a name.
|
|
|
|
LoadSystemFont
|
|
~~~~~~~~~~~~~~
|
|
|
|
.. _scriptref_fonts:
|
|
|
|
.. code-block:: pascal
|
|
|
|
function LoadSystemFont(const SysFont: TFont; const FontName: string):
|
|
boolean;
|
|
|
|
This font loads a previously created Font with the name specified by
|
|
*FontName*.
|
|
|
|
Example:
|
|
|
|
.. code-block:: pascal
|
|
|
|
program new;
|
|
var
|
|
Font : TFont;
|
|
begin
|
|
Font := TFont.Create;
|
|
Font.Name := 'Courier New';
|
|
Font.Size := 10;
|
|
Font.Style := [];
|
|
LoadSystemFont(Font,'test');
|
|
DisplayDebugImgWindow(0,0);
|
|
DisplayDebugImgWindow(150,50);
|
|
DrawBitmapDebugImg(BitmapFromText('BMP[0] has not been freed','test'));
|
|
Font.free;
|
|
end.
|
|
|
|
LoadFont
|
|
~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function LoadFont(const FontName: string; shadow: boolean): boolean;
|
|
|
|
Load the font specific by the *FontName*. The font has to recide in the Fonts
|
|
directory.
|
|
|
|
|
|

~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function FreeFont(const FontName: string): boolean;
|
|
|
|
This function is used to free a font identified by *FontName*.
|
|
|
|
|
|

|
|
~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function BitmapFromText(const text, font: String): integer;
|
|
|
|
This function creates a bitmap from a string *text* with the given *font*.
|
|
For an explanation on how to use and work with Bitmaps, please refer to
|
|
:ref:`scriptref_bitmaps`.
|
|
|
|
TPAFromText
|
|
~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function TPAFromText(const text, font: String;var w,h : integer): TPointArray;
|
|
|
|
This function creates a TPA from a string *text* with the given *font*.
|
|
For an explanation on how to use and work with TPAs, please refer to
|
|
:ref:`scriptref_tpointarray`.
|
|
|
|
TPAFromTextWrap
|
|
~~~~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
procedure TPAFromTextWrap(const text, font: String;var w,h : integer;var TPA : TPointArray);
|
|
|
|
A wrapper function for the previously mentioned function. Required to
|
|
work arounds bugs in the interpreter.
|
|
|
|
MaskFromText
|
|
~~~~~~~~~~~~
|
|
|
|
.. code-block:: pascal
|
|
|
|
function MaskFromText(const text, font: String): TMask;
|
|
|
|
This function creates a Mask from a string *text* with the given *font*.
|
|

|
|
|
|
A general function for reading text.
|
|
Reads text at (*atX*, *atY*) with a minimal vertical spacing of *minvspacing*
|
|
and a maximal vertical spacing of *maxvspacing*, the text colour should match
|
|
the colour *color* with the given tolerance *Tolerance*; the length of the text
|
|
is specified with *len*. Finally, the font to use for the identifying is
|
|
specified with the fontname *font*.

|
|
and a maximal vertical spacing of *maxvspacing*, the text colour should match
