Today, my friend uses Photoshop to process the picture to save the specified size, but she only to the centimeter to shape the sense, but in the software to save the picture does not have this unit, can only save the units of pixels; Other software can only be saved in inches. I went to the internet to find the next information, finally found the conversion formula, special record:) 72 Megapixels/inch = 28.346 px/cm300 megapixels/inch = 118.11 px/cm1

Getting or Setting PixelsThe Safe (slow) Suppose you is working on an image = img[y, x]; Setting the pixel on the y-th row and x-th column are also simple IMG[y,x= Color; The fastThe Image pixels values is stored in the Data property, a 3D array. Use the If you need to iterate through the pixel values of the image.For example, in an grayscale image (Image= Imagegray[x, y]; You would does this:= Imagegray. Data0]; Ge

JQuery implements the method of displaying a floating window in 100 pixels in the page drop-down list. jquery window This example describes how to implement a floating window in 100 pixels in the drop-down list of jQuery pages.

Why is the height of a label several pixels higher than that of img ?, Label img Style: Li {Height: 300px;A {Display: block;Img {Width: 100%;Height: 100%; }}}Effect: Knowledge supplement: by default, the width and height are the height of the lines in the inline element automatically calculated by the browser, so you can set the background color.The height of the inline element is related to font-size, but not determined by font-size.

How to keep pixel perfect in Photoshop @Iamkikidong when designing Web pages and program interfaces, most designers are worn out to ensure that each pixel's color, texture, and location are accurately presented. Accidentally, some of the most commonly used operations such as moving, rotating and pasting will make your hard work to naught. However, if you can make some small changes to your workflow, you can always keep the quality of the work in the project. Pixel Perfect Rotation If you're n

Move the mouse up, add N pixels to the left of the element, and move the mouse over the meeting slowly to the original position. This control is developed based on Jquery and should reference the Jquery framework. Control Code The Code is as follows: $. Fn. myNudge = function (){Var self = $ (this );Self.css ({position: "absolute"}); // Let this element be absolutely positionedVar selfLeft = self.css ("left ");Var selfTop = self.css ("top ");Se

Use the followingCodeThe font size will not increase, but will decrease:Size = (INT) mtext. gettextsize () + 1;Mtext. settextsize (size );Later, we found that the returned value of gettextsize is measured in pixels (PX), while that of settextsize () is measured in sp. This result is returned only when the units of the two are inconsistent.You can use another form of settextsize () to specify the unit:Settextsize (INT unit, int size)Typedvalue. complex

You can use macros defined by opencv to extract pixel values.Assume that the gray-scale image can be used to access the pixels in column J of its line I: cv_image_elem (image, uchar, Y, X)For a color imageCv_image_elem (image, uchar, Y, 3 * X)Cv_image_elem (image, uchar, Y, 3 * x + 1)Cv_image_elem (image, uchar, Y, 3 * x + 2) Cv_image_elem is a macro, # Define cv_image_elem (image, elemtype, row, col )\(Elemtype *) (image)-> imagedata + (image)->
