Capture2Text Readme -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- What is Capture2Text? -------------------------------------------------------------------------------- Capture2Text enables users to do the following: * Optical Character Recognition (OCR) Allows the user to quickly snapshot a small portion of the screen, OCR it and (by default) save the result to the clipboard. * Speech Recognition Using speech recognition the user can speak into their microphone and Capture2Text will convert the speech to text. If the speech recognition technology is not 100% sure, Capture2Text will present the user with a list of the most likely transcriptions. The selected result will (by default) be copied to the clipboard. -------------------------------------------------------------------------------- How to Launch Capture2Text (no installation required): -------------------------------------------------------------------------------- 1) Unzip the contents of the zip file. Make sure that there are no Asian or other non-ASCII characters in the path where you unzipped it. Also, if you are on Windows 7, don't unzip it to the Program Files directory (this will avoid issues related to write privileges). 2) Double-click on Capture2Text.exe. You should see the Capture2Text icon on the bottom-right of your screen (though it might be hidden in which case you will have to click on the "Show hidden icons" arrow). -------------------------------------------------------------------------------- OCR Language Support: -------------------------------------------------------------------------------- Capture2Text can OCR the following languages: Afrikaans Frankish Maltese Albanian French Norwegian Ancient Greek Galician Polish Arabic German Portuguese Azerbaijani Greek Romanian Basque Hebrew Russian Belarusian Hindi Serbian Bengali Hungarian Slovakian Bulgarian Icelandic Slovenian Catalan Indonesian Spanish Cherokee Italian Swahili Chinese Japanese Swedish Croatian Kannada Tagalog Czech Korean Tamil Danish Latvian Telugu Dutch Lithuanian Thai English Macedonian Turkish Esperanto Malay Ukrainian Estonian Malayalam Vietnamese Finnish Maltese By default only Chinese, English, French, German, Japanese, and Spanish are installed. To acquire other languages: 1) Download the appropriate OCR language dictionaries from: http://code.google.com/p/tesseract-ocr/downloads/list These files end in ".tar.gz" (ex. tesseract-ocr-3.02.rus.tar.gz). 2) Open the ".tar.gz" file you just downloaded with 7-Zip or similar decompression software and navigate to the directory that has the file that ends in ".traineddata". 3) Drag the ".traineddata" file (and any other file in this directory) to this path in the Capture2Text directory: Capture2Text\Utils\tesseract\tessdata 4) Restart Capture2Text Note: Arabic and Hindi are more CPU intentive and will thus be slower to OCR. -------------------------------------------------------------------------------- OCR Usage: -------------------------------------------------------------------------------- Press the OCR capture key (default: Windows Key + Q) to start the capture. Now, using your mouse, resize the capture box over the area of the screen that you want to OCR. A preview of the captured OCR'd text will appear in the top-left corner of the screen. Press the capture key again or the left mouse button to complete the capture. The captured screen area will be OCR'd and the textual result will be stored in the clipboard by default. To cancel an OCR capture, press Esc. To move the capture box, hold down the right mouse button and drag the mouse. To nudge the capture box, use the arrow keys. To toggle the active capture box corner, press the space bar. To change the OCR language, right-click the Capture2Text tray icon, select the OCR Language option and then select the desired language. To quickly switch between 3 languages, use the OCR language quick access keys: Windows Key + 1, Windows Key + 2, and Windows Key + 3. When the Tesseract versions of Chinese or Japanese is selected, you should specify the text direction (vertical or horizontal) using the text direction key: Windows Key + W. The text direction will not have any effect on the NHocr Chinese and Japanese dictionaries. Using the Preferences dialog, you can change the following OCR settings: - OCR Hotkeys. - Current OCR Language. - The 3 Quick-Access OCR Languages. - Capture Box color and opacity. - Enable/Disable the preview box and change its colors, font and opacity. - Change the text direction (used for Chinese and Japanese). -------------------------------------------------------------------------------- Speech Recognition Language Support: -------------------------------------------------------------------------------- Capture2Text can perform speech recognition for the following languages: Afrikaans French Polish Chinese German Portuguese Czech Italian Russian Dutch Japanese Spanish English Korean Turkish -------------------------------------------------------------------------------- Speech Recognition Usage: -------------------------------------------------------------------------------- Press the speech recognition capture key (default: Windows Key + A) to start the capture. You will see a box that says "Recording..." in the top-left corner of your screen. Speak a word or phrase or sentence into your microphone. Capture2Text will automatically recognize when you are done speaking and will display a box that says "Analyzing...". The speech recognition will take a couple of seconds. When the speech recognition is complete you will see a list of possible transcriptions to choose from. When you choose a transcription, it will be stored in the clipboard by default. When the results windows is displayed, you can press Enter to select the first transcription or use the number keys (1-9) to select the corresponding transcription. To cancel a speech recognition capture, press Esc. To change the speech recognition language, right-click the Capture2Text tray icon, select the Speech Recognition Language option and then select the desired language. To quickly toggle between 2 languages, use the speech recognition language hotkey: Windows Key + 4 Using the Preferences dialog, you can change the following speech recognition settings: - Speech recognition Hotkeys. - Current speech recognition Language. - The 2 speech recognition languages to toggle between. - The properties of the Results window (font, color, number of results). - How much silence to wait for before recording stops. -------------------------------------------------------------------------------- Output Options: -------------------------------------------------------------------------------- By default, the OCR'd or speech recognized text will be placed in the clipboard. You also have 3 more ways to output the text. To send the text to a pop-up window you can right-click the Capture2Text tray icon and select Show Popup Window. To send the text to whichever textbox currently contains the blinking cursor/I-beam, right-click the Capture2Text tray icon and select Send to Cursor. Advanced: To send the text directly to a window/control (for example, Notepad++), first fill in the Send to Control settings in the Preferences dialog. Once this is done you may enable/disable the option by right-clicking the Capture2Text tray icon and selecting Send to Control. Using the Preferences dialog, you can change the following output settings: - Text to prepend/append to the captured text. - Enable/Disable outputting to the clipboard. - Enable/Disable outputting to a popup window. - Popup window properties (default width and height). - Enable/Disable sending the output text to the cursor. - Enable/Disable outputting to a control. - Additional command to send to the output control. -------------------------------------------------------------------------------- Configuration: -------------------------------------------------------------------------------- Right-click the Capture2Text tray icon in the bottom-right of your screen and then select the "Preferences..." option to bring up the Preferences dialog. -------------------------------------------------------------------------------- Substitions: -------------------------------------------------------------------------------- Sometimes Capture2Text consistently makes the same OCR mistakes such as recognizing an "M" as "I\/|". By editing the substitutions.txt file in the Capture2Text directory, you may tell Capture2Text to substitute one text string for another text string. Just find the appropriate language section and add one substitution per line in this format: from_text = to_text Example (adding 3 substitutions to the English section): English: I\/| = M >< = X some%space%text = some_text To create a substitution regardless of language, add the substitution to the "All:" section. Special tokens and escape characters: %space% = Space ch...
