The Aspect Ratio Calculator allows you to calculate the missing value within a ratio, this is useful for resizing images, scaling objects, models and for. Whereas converting pixels to inches can be helpful in outputting a digital image to a physical image, converting inches to pixels can help you bring a physical image into digital form.Ĭongrats! You’ve successfully converted pixels to inches. This can be useful to know when printing a physical copy of the image or displaying it on a larger screen.įormula: Pixels / DPI = Inches Converting Inches to Pixels For example, when you resize a photo to fit on a website or resize a. If you know the pixel width and height of your image, our calculator will convert those dimensions into its display size in inches. The 6:4 Aspect Ratio Calculator allows you to enter height or width and get the. About the Formulas Converting Pixels to Inches Page Size Converter: Calculate how to resize your document if its in the wrong proportion for your desired size. So, what we’re really seeking to understand here is pixels-per-inch (PPI). This is advanced tool for batch conversion with lot of image processing features from rotating, image resizing, adding an anti-theft 'X', overlaying text and/or a logo onto the image to more advanced requirements such as leveling RGB, HSL, brightness. See all the sizes we can print from your file. In computer terms, we use pixels instead of dots. There's no need to use functions when setting the width/height.DPI, which stands for dots-per-inch, is a measure used in printing to calculate the number of dots that can fit into a line with a width of one inch. And undefined * container.width() is NaN - Not a Number. Stranger still, when you actually call setImageDims in the resize event handler, you don't provide that value at all, meaning it's undefined. And you basically "rename" it to container inside the function, so perhaps that'd be a better name to begin with? And $imgAspectRatio would imply that it's a jQuery object. selector is fine (if non-descriptive), but content_area is snake_case whereas you use camelCase (which is the JavaScript convention) everywhere else. There's little system in your variable-naming. Of course, you already have a resizeImage function which does the exact same thing - it's just hard coded to only use the body as its reference. For another, I'd just find resizeImage or maybe resizeToMatch to be more straightforward. For one, I rarely see the need to abbreviate words. There's a lot of code here, so I'll just start with a single function: setImageDims I have also created a rudimentary fiddle to illustrate the imageCalc(), setImageDims(), and imageResize() functionality here. JQuery('.menu-main-container').css('display', 'block') ![]() SetImageDims('.com-background > img', '#main-content') setImageDims('.com-background > img', '#main-content', ratio1) var ratio1 = imageCalc('.com-background > img') We can generate another simple formula: Angular size in degrees (size 57.29) / distance No doubt you can figure out the formulas for minutes and seconds of arc. JQuery('.mobile-contain > a').bind(event, function(), 7000) Multiplying 57.29 3,600 seconds per degree we get 206,244 meaning an object at a distance of 206,244 times its size displays an angular size of 1 second. Var ua = erAgent var event = (ua.match(/iPad/i)) ? 'touchstart' : 'click' Note: all these functions work (I do have an error imageResize('.com-background > img', ratio1) ratio1 is not defined within the window.resize function. The below scriptfile includes the issue above, and some functionality for mobile, and an overlay. First, an image gallery I have setup and now, Iframes. Now, I have got these functions working, however I feel like they could be more efficient/clean. I have created a set of functions to calculate the aspect ratio of an image, set a height/width on document.ready and on window.resize resize the image. ![]()
