TCompareRules = packed record
Color, Tolerance: Int32; // Color and tolerance. Color can be -1 to match any color.
UseShadow: Boolean; // If the fontset has a shadow, it can be used to improve recognition.
ShadowMaxValue: Int32; // Max brightness of shadow, Shadows are black so this is often low.
Threshold: Boolean; // Threshold the image? If so all above fields are ignored.
ThresholdAmount: Int32; // Threshold amount.
ThresholdInvert: Boolean; // Threshold invert?
UseShadowForColor: Boolean; // Find and offset shadows by (-1,-1) and use most common color to recognize text with.
MinCharacterMatch: Int32; // Minimum hits required to match a character. Useful to remove smaller characters (like dots) that are often misread.
end;IsStatic parameter:
If the starting position (X1,Y1) of the text never changes the text is static which greatly increases accuracy and speed. If this is the case you must pass the pixel perfect bounds of the text you want to read.
MaxWalk parameter:
How far the OCR looks on the X axis before giving up. By default this is 40 so if no characaters are matched in 40 pixels the function finishes.
LocateText function:
LocateText does not OCR! In simple terms a bitmap of the text is created (Using DrawText) and searched for. Color can be -1 though each pixel of the text must be the exact same color.
