The arrow keys from the num pad will move the cursor in the direction desired. Depressing the key for a period of time will accelerate the movement of the cursor in that direction. The Arrow Keys have been designed to act as an alternative to Mouse interaction. > File and Directory Access AdvanTex comes with a complete file editor which enables you to name files, change these names, import files from other directories and export files to other directories throughout your system. Refer to your manual for complete details on proper file creation and pathing techniques. Basic DOS rules apply. When editing or naming a file or directory, there are three keys to remember. The home key on your num pad will move the cursor line to the beginning of the file or directory name. The left and right arrow keys will allow you to skip over the name character by character. The back space key will erase the next character to the left. > Flip Image Functions This creates a mirror image of the original graphics file. What first appeared on the right hand side of the image, is now on the left hand side. The Flip Vertical function reverses the pixel columns from top to bottom, creating an upside down mirror image of the original graphics file. > General Help The help screens have been designed to give you a few basic operating instructions on the primary functions and capabilities of AdvanTex. The screens can be used as a quick reference source to refresh yourself on how to complete the task at hand. These screens do not replace the manual, however. Thorough explanations and instructions of all capabilities of this program should be sought in the user's manual. The help screens are listed alphabetically starting with Arrow Keys and ending with Zoom Functions. > Function Keys There are function keys which correspond to the primary functions of Advantex. Any of these functions may be activated by (1) placing the cursor over it and pressing Enter, 2) placing the cursor over it and pressing the left button on your mouse, and 3) pressing the function key (F1- F10) that corresponds to appropriate function. > Invert Page The Invert Page feature allows you to create a negative of the image by changing all black pixels to white pixels, and all white pixels to black pixels. The image will not be permanently altered unless you save the file, so feel free to play around with this feature. > Keyboard AdvanTex can be operated by the keyboard. AdvanTex is a program that is easy to move around in. The keypad keys change their meaning logically when in graphics mode. > Menu Mode key usage CURSOR LEFT selects menu to left of current CURSOR RIGHT selects menu to right of current CURSOR UP up one menu / list item CURSOR DOWN down one menu / list item HOME top of a menu or list END end of a menu or list PG UP top of a menu / up one list page PG DN end of a menu / down one list page ENTER select function under the menu bar ESC cancel current function F1..F10 Short cut keys for specific functions > Graphic Mode key usage CURSOR LEFT left on the graphics display CURSOR RIGHT right on the graphics display CURSOR UP up on graphics display CURSOR DOWN down on graphics display HOME up and left on graphics display END down and left on graphics display PG DN down and right on graphics display PG UP up and right on graphics display ENTER anchors current cursor position ESC cancels current function > Mark Area, Cutout, and Erase AdvanTex comes with the capability to draw a box around a specific area of the graphics file you wish to edit. There are no size limitations to how big or small the box must be. To draw a box, depress the F2 function key or the MARK AREA selection under the EDIT Menu. Initially you will have the arrow cursor and a pair of intersecting lines. Place this intersection in any one of the four corners of the box you wish to draw. Press enter to anchor this corner of the box. Now use your mouse or arrow keys to draw the rest of the box. Press enter when you are satisifed with where the box is located. You may now save this boxed area as a new ATX, PCX, or TIF file. After marking off an area, you may choose to erase the area inside or outside of the box. To erase the area within the box press F3 function key. To erase the area outside of the box, press F4 function key. Either function may be selected from your Edit menu. > Straighten Page by Page Rotation If you wish to change the angle or orientation of the graphics file slightly, you can use the Straighten Page function. Select "Straigten Page". The arrow cross hair cursor appears with the intersecting lines. The object is for you to draw a reference line that AdvanTex can use as a guide for the amount you want to rotate the image. With the cross hairs at an initial position, press Enter. This temporarily anchors one end of the line and produces a little square drag ICON (dragon). Draw the line along some edge in the picture that you want horizontal or vertical by moving the dragon to the right, left, up, or down with the arrow keys. A rubber line will follow from the anchor point to the dragon. You can use the "+" and "-" keys to hop the dragon to either end of the rubber reference line. F10 will zoom you in and out. When you are satisfied with the new angle and positioning of the reference line, press enter. The line is now anchored. The program will ask you if you wish to Go Back or Straighten Page. To begin the page rotation, move the black bar to Straighten Page and press the ENTER key. Note: The larger the angle the program needs to shift the page, the longer it will take to complete the task. This is particullarly true when using the EMS simulator. Larger angles shifts may also cause some distortion of the image. > Saving & Loading Image Files When you initially scan in a page, it is held in your EMS simulator or your EMS card. At this point, the file has no name. If you wish to save this file, you must assign it a DOS compatible file name. To assign, change, or reformat a file name use the functions available under the FILE Main Menu. The LOAD FROM selection allows you to activate a graphics file that has already been saved to hard disk. The SAVE AS selection allows you to assign a name to a file that has just been scanned. The SAVE AREA AS selection allows you to name a boxed area and/or reformat the graphics file in ATX, PCX, or TIF file forms. The DISCARD IMAGE allows you to remove the scanned image from your screen without copying it to permanent memory. QUIT AdvanTex exits you from the program and back to the DOS prompt. > How to Scan To scan an image, select the OCR menu then select the Scan Page function. Alternatively you can simply press F3. The computer will now begin scanning. > Scanning Options To change any of the default selections, select the "Scanner Settings" control panel. > Control Panels Control panels are windows which let you change values which control Advantex. > Changing a Control Panel Option: Move the cursor bar to the selection you want to modify and press the Enter key. Move the cursor bar to the new setting you want and press Enter again. The setting will change to the value you selected remain active until you change it again. Scanner settings are stored in the startup profile. activate the scanner, place the cursor over the SCAN selection box, and press Enter. > Exiting From a Control Panel To cancel your selections, place the cursor over the CANCEL selection box, and press Enter. To return to the main menu, press ESC. > Zoom Functions The ZOOM OUT display is a compressed view of the graphics page that you normally see after a page scan or load. When you wish to take a closer look at a portion of your graphics file, 1. Press the F9 key to activate the select targeting cross hairs. 2. Use the CURSOR keys to move the target cross hairs to the desired location on the ZOOM OUT display. 3. Toggle between ZOOM OUT and ZOOM IN at the cross hair point by pressing F10. > Test Locating Symbols The TEST LOCATE funtion operates on a scanned or loaded image to locate all symbols meeting your current OCR criteria. The OCR criteria most affecting this function is the spot filter size which determines the size of the least spot to be considered for OCR and the maximum symbol size whic determines the maximum height or width of a symbol to be considered for OCR. Symbols falling outside of the OCR criteria range are not marked and are ignored during OCR. The bitmap is written on to show the location, height baseline for each line of symbols. You must rescan or reload a new image after using this function. > Test Locating Words The TEST LOCATE WORDS performs the OCR word separation function on a scanned or loaded image. This allows the user to view Advantex's word separtor capabilities for the text on the page. The word space breaking is automatically recalculated EVERY line and should be accurate in all but the tightest cases (typeset with very very small word breaks). To run the test use TEST LOCATE WORDS on the EDIT menu. Each word is highlighted by writting a halftone on the bitmap and the the dynamically calculated word space break criteria. You must rescan or reload a new image after using this function. > Using the Separate Lines Function The SEPARATE LINES funtion operates on a scanned or loaded image to cut lines where the symbols of one line accidentally touch the symbols of the line following. To use this function set the maximum symbol size to a rectangle just taller and wider than the biggest single character you want to consider for OCR (including the decenders). The select the SEPARATE LINES function. ATX will process the bit map and physically separate the touching lines. After separation you can then use the normal OCR functions. > Handling Accidental Ligatures (Touching Symbols) You can handle accidental ligatures two ways. The first is to add these touching symbols to a font by training. The second is to enable or disable the double error marker (See: Text Settings Menu) which outputs two error marker symbols on detection of a wide error character.
