I have looked around at the available tools and I haven't seen anything that I am interested in. I think the ones that mimic actually calipers are far to bulky for my tastes - you have to move it around and rotate it. I would rather just click two points and get an estimate. That is why I thought I would ask about it here. I think it would be perfect for screenshot captor. I use it every day.

Presumably, if the user selected two points to define a line, you would then know how many pixels make up that line (roughly). The user would assign a length to that measurement. That would assign a scale factor at that zoom level. So any other lines drawn could have a measurement associated with it. I know this works because that is what I do by hand with printed engineering drawings. I'd be very happy with this functionality.

I would only want to zoom in to better define either end point of a line, making sure that it lined up as closely as possible with the feature that I want a measurement estimate from.

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?

I have a folder where I am storing screen captures. I have the default new file name template set as "sc%num%" which will create screen captures sc001.png, sc002.png etc. This works great. Is it possible to tell Screenshot Captor to start at a specific number? Say the folder is empty and I want to start naming then images sc021.png.

Cheers and thanks,
Troy
