25 maj 2020 · I have a list in my slide with one item in one object. I need to keep equal distance between the objects. Using distribute vertically or horizontally options does not bring what I am looking for.
27 sie 2018 · One thing you could do is using the Console tab to compute the horizontal or vertical distance between two elements using dimension/position properties/methods such as Element.getBoundingClientRect() or HTMLElement.offsetTop, but I guess you are looking for something that works more like a tool rather than coding your own solution.
7 mar 2012 · I have developed an algorithm to calculate the height(m) based on # of pixels and the distance from the object that you are calculating the height from. I am just lost on how to calculate pixels in an image, besides reading the metadata for the height and width in pixels of the whole image.
9 lut 2018 · This extension measures the dimensions from your mouse pointer up/down and left/right until it hits a border. So if you want to measure distances between elements on a website this is perfect. It doesn't really work with images because there the colors change a lot pixel to pixel. Images & HTML Elements.
22 cze 2023 · pixel size = 2 * tan ( horiz.fov /2 ) * distance / image width in pixels. So at 50 mm on 12 Mpx full frame at 5 m distance you get. tan (39.6°/2) * 5000mm / 4000 = 0.45 mm
12 cze 2017 · If you know the actual width or height and camera-to-object distant, you can easily calculate a ratio size-to-distance. Say a object is 3 meters wide and a picture is taken with the camera positioned 12 meters from the subject. The ratio size-to-distance is 3÷ 12 = 0.250.
Measure distance. Quickly determine the distance between any elements on your screen. Hold dimensions on the screen. Support short distance.
