Un Scan It 6.0

Un Scan It 6.0 is a simple and effective tool which allows you to automatically convert hard copy graphs to (x,y) ASCII data at Full Scanner Resolution!

UN‑SCAN‑IT works with any scanner, digital camera, or other image input device to digitize strip charts, instrumental output, old graphs, published graphs, etc. In addition to the many digitizing features, UN‑SCAN‑IT also integrates peak areas, smooths data, takes derivatives, re‑scales graphs, and exports the (x,y) data for use in other software programs.

If you have ever had to guess at the data values on a printed graph, hold two graphs up to a light to compare the features, use the cut and weigh technique to find peak areas, use a planimeter, or "squint and click" on each point with a digitizing tablet, then you will find UN‑SCAN‑IT to be the solution of choice. Digitizing graphs with UN‑SCAN‑IT is accurate, quick, and easy.

Major Functions:

• Automatically digitize strip chart and (x,y) recorder output
• Compare and analyze data from graphs that are on different scales
• Compare your data with published graphs of other investigators
• Digitize old graphs for comparison with new data
• Re‑scale and append existing previously printed graphs
• Graph data, background subtract, smooth data, find peak areas, etc.
• Analyze and store hard copy output in digital (x,y) form on disk
• Prepare publication quality graphs from messy originals
• Export data to other spreadsheet, data analysis, and graphics programs
• Save the data in (x,y) ASCII, JCAMP, and clipboard format

Enhancements:

• Drag and Drop Setup: This new setup method allows all of the setup parameters to be defined by simply dragging icons to their appropriate locations on the graphical image.
• Colored Data Recognition: The software can now use color averaging to recognize and digitize colored data lines and points.
• Grayscale Data Recognition: The software can now use a grayscale intensity range to recognize and digitize grayscale data lines and points.
• Improved Help Menus with Graphics: The new help screens contain more complete help descriptions, as well as new graphic images accompanying the description.
• Improved Setup Icons: The software now displays a variety of setup icons on the graphical image that clearly identify all of the current setup parameters and their locations.
• Polar Coordinate Digitizing: Graphs that have been recorded using a polar (r,) coordinate system can now be digitized in manual mode.
• Raster Scan Scatter Plot Mode: This new digitizing mode assigns a single (x,y) data point at the center of contiguous pixels of defined data color.
• Graphical (x,y) Data Eraser: The new data eraser allows data points that were erroneously digitized due to stray marks, other data lines, axes lines, etc. to be erased from memory. This option can be very useful for deleting groups of stray digitized data points.
• Horizontal/Vertical Grid Filter: A new grid filter that ignores horizontal and vertical lines within the search region can now be used to filter grid lines.
• Intersecting Line Following: The software can be set to automatically pause when an intersecting line is encountered, or automatically estimate the continuance point of the line and continue automatically.
• Auto Dashed/Dotted Line Following: This new feature allows the software to automatically estimate and continually update the vertical limits when following dashed or dotted lines.
• Variable Surface Point Assignment: This new point assignment method allows the software to follow the top surface of the curve where the peaks go up, and the bottom surface where the peaks go down. This method is useful for digitizing graphs that contain both sharp upward and downward peaks.
• Improved Transform Resolution: The final number of transformed data points can be selected as a priority, in addition to the regular method of selecting the absolute x data spacing.
• Increased Number of Data Points: The maximum number of digitized (x,y) data points has been increased to 30,000 per data file.
• Multi-Point Manual Digitizing: This version now contains a manual digitizing mode that will continuously digitize data points when the mouse is moved along a curve while depressing the mouse button.
• Icon Slider: This feature allows all the current setup icons (and their corresponding location settings) to be moved in the desired direction. This feature can be especially useful when used in conjunction with the Save/Load Axis Setup Parameters option. By using these options, multiple graphs with similar axis parameters can be easily digitized by simply saving and loading the axis setup parameters, and then sliding the axis setup icons to account for the shifts that may have occurred during the scanning process.
• Sample Images: Several sample images are now included in the UN‑SCAN‑IT folder. These sample images are useful in identifying the axis setup parameters, and provide useful examples of the digitizing process.
• New User's Manual: The UN‑SCAN‑IT User's Manual has been enhanced with additional graphical examples, chapter guides, and additional feature descriptions.
