Screenshot Captor / Feature Request: Measure based on a scale
« on: May 16, 2017, 03:06 PM »
I frequently have to measure engineering drawings that are not to scale. They do have dimensions markers on them with listed values. I have to take a ruler and measure that line. Since I know what the length of the line is supposed to be and what it actually is measured to I can use that as a scale factor/ratio (known value divided by the measured value) . I can then measure any other distance on that image and multiple it by the scale factor to determine what it should be.
I know there are problems with this method, particularly if the aspect ratio is different from the original. It would still make for a pretty good approximation. I believe this would be a valuable addition to the ScreenShot Captor set of tools. I see the process working like:
1. Take a screen capture
2. use a "caliper" tool to identify a known length on an image. Enter in the corresponding known length
3. use a calibrated measure tool to select two points on the image - the calibrated length will be displayed.
It really doesn't have to be much more sophisticated than that. Maybe there could be an option to apply a horizontal and vertical calipers to attempt to correct for aspect ratio errors?
Thanks,
Troy
