PatchTool PatchReader-Custom chart

|
In this mode you select the numbers of rows and columns of the chart or target you want to measure; there is no need to open a file of the proper size beforehand. Click on the "Start" button once the chart dimensions are defined. You can select any patch to make individual measurements, or use a timer to automatically make measurements at fixed time intervals. It is also possible to take measurements one row at a time, by scanning the instrument from one side of the chart to the other. Select the Strip mode with the menu within the “Measurement mode” box; the contrast between neighboring patches must be high enough so that the instrument automatically detects a transition OR the patches are separated by contrast gaps consisting of thin black and/or white lines before and after each patch (Note: Targets with contrast gaps can easily be created with PatchTool). Click the “Stop” button at any time. The measurements are saved in a CGATS type file which can be readily opened by PatchTool and most programs which can read color files.
Screenshots of the "Unconstrained measurements" mode are shown on the previous page. Screenshots of the "PatchTool file" measurements mode are shown on the following page. |
