cropping body equation, when we need to crop a vertex, these six equations are enough. However, when we want to determine the visibility of a region, we perform some additional calculations. As shown in 2, the relationship between an object and a projection object can be roughly divided into four situations: surrounded, surrounded, intersection, and separation. The largest light blue rectangle in the figure contains the entire projection body. The sm

We know that displaying images in HTML is usually tagged with an img control, and of course resizing is easy.However, a specific IMG size will appear, showing a larger size and a length-to-width ratio that does not match the specific IMG size. and caused the compression problem, the picture squeeze is very serious, looks very uncomfortable.This time can be used in CSS background-image this property to solve. Use the div tag instead of the IMG tag and set the div's background image.Because Backgr

picture. The width is the same. Width:Math.round of the right picture (ScaleX * 300), Height:Math.round of the right picture (ScaleY * 300), Vi. questions: Selection.width; Selection.height How do these two values get? I want to first make the big things clear, and then write a few more about how to get the key values in this analysis. Must be this plug-in is very large, code a lot of complexity, so can only step by step in depth. This is the plugin URL: http://odyniec.net/projects/img

Web page to crop pictures, do not need to go through the server. This is accomplished with the Https://github.com/mailru/FileAPI framework. cooperate with Jcrop. Advanced browsers use canvas cropping, IE6 7 8 use flash over. Core code: var el = $ (' input ').

A pair of 1024*768 size pictures, cropped to 240*240 size, not distorted after cropping, as far as possible to retain the theme meaning of the picture. The method I used: 1. First the picture and so on to the scale of the size can be cropped; If it is a wide picture, then the height of the scale to height = 240px, a narrow picture (height is greater than width) by width and so on scale; 2. Cut the center by the long width format; Retain the middl

NET implementation code, a closer look at the thumbnail is a bit clearer than the original, but the cost is that the thumbnail file is larger than the original, so if you want to make a large picture of the screen full of the monitor clearer, then the picture takes up space and network traffic must b

05. Image cropping for Windows Store app, In the Win Phone Silverlight api, there is a PhotoChooserTask selector that specifies the width and height attributes. when selecting an image, You can crop the data by using the following code: PhotoChooserTask photoChooserTask = new PhotoChooserTask (); photoChooserTask. completed + = new EventHandler After selecting an image, you can crop it: This interaction is imitated here, and similar interaction i

The upgraded version of the Gaussian Blur function, with the cropping area. The check_rect () function is used to process the cropped area rectangle. If you do not want to crop the image, you only need to set left, top, right, and bottom to 0. In addition, the storage format of the bitmap is up and down. If you want to crop the image normally, you only need to set bottom to-bottom. Bool check_rect (INT width, int height, Int left, Int Top, Int ri

The image cropping function has been being developed recently: Download the image (webmercator projection) from the image server. The service interface needs to input a polygon of the WGS84 coordinate to return the webmercator image. The client needs to convert the image to Gaussian projection (beijing54) It is considered that the geographic coordinate of WGS84 to Beijing 54 Gaussian projection is reversible with seven parameters. The projection tra

Matrix changes generally include three parts: WVP. This article is devoted to explaining some principles in the Construction of P Matrix, that is, projection cropping matrix. Learn more before you start. The role of the projection matrix is to save the objects in the cone and eventually correspond to the viewport. The process is roughly three steps. First, the cone is projected to become a so-called parallel pipeline observer, which can be understood

This article mainly introduces how to use JavaScript + canvas to crop images. For more information, see canvas as a label that allows us to use script plotting, it provides a series of complete attributes and methods. We can use this to achieve graphic rendering, image processing, and even simple animation and game production. The canvas label has only two attributes: width and height, which are used to set the width and height of the canvas. If the canvas is not set through the label attribute
