Hi Friend,

I would like to get some detailed descriptions about some terms used in the coding.

1) Slowmatch and FastMatch palette parameter in 'Color Resolution'? I had tried going through the SDK, but couldn't get a detailed explanation.

2) Order parameter in 'Color Resolution' - RGB (Loads the image as Red, green, blue - Explanation other than this.), ROMM

3) Legacy page parsing algorithm: (Identifies the page-parsing algorithm used in the toolkit till version 10.0 is what I found).

4) All Dithering methods. Like what does Burkes's method do?

5) Panel - GET_RED_PANEL, GET_BLUE_PANEL, etc parameter of  'Color Separator'.

6) An example for Create zone which uses all parameters as Char Filter, Zone fill, Recognition method.

7) LanguageCharacterPlus, LanguageCharacterPlusFilter, LanguageCharacterFilter, - parameters of 'Apply OCR'.

I would appreciate if you could send me the descriptions as soon as possible.

Thanks and have a good day!!!

1-Both terms are used to refer to color matching techniques
The "Slow match" is slower, but does a better job for color matching. "Fast Match" is faster, but may not pick the best possible match.

2-Regarding the order parameter issue you can refer to the following link for detailed information

3-The Legacy page parsing algorithm: is used for backward compatibility

4-Regarding the Dithering methods: These are standard
dithering methods. There are for people that want to use a specific dithering
method. In most cases, Floyd-Steinburg is the best choice. For information about a specific dithering method,
you can find it on the Internet by using Google.

5-regarding the panel: What help file is this in? I am assuming that this is for the color
Separation function. The panels are the color planes. I can not find these in any help file.

6-An example for Create zone: please provide me with more details about what you are trying to do?

7-The apply OCR: The OCR engine supports many different
languages for recognizing text. For a language to be used in the recognition process it must be set as active.

To activate the languages that will be used in the next recognition process,
Call SelectLanguages. In addition, special character options can also be set
For characters in the active languages using LanguageCharacterPlus,
LanguageCharacterPlusFilter and LanguageCharacterFilter. To determine what
Languages have been activated for the OCR engine, call SelectedLanguages

To determine whether a specific character is enabled in the active languages,
Call IsCharacterEnabled.

DefaultSpellLanguages property gets the default languages used for checking
Spelling. All available spelling languages available to the OCR engine are
Default and are used for checking spelling.
