Opencascade color scale [Email protected] Abstract.The color scale is a specialized label object that displays a color map and an accompanying numerical scale for color mapped or contour data plots. as the geometry modeling kernel of Salome, opencascade provides the color scale function. the paper focus on the usage of

Browsers such as IE and chrome and zoomStill a few years ago, zoom it was just IE's own private toy, but now, in addition to the Firefox browser, the other, especially chrome and mobile browsers have been well supported by the Zoom attribute:zoomThe literal meaning is "zoom", a concept commonly used in photography.

In the previous chapter, we used a very important concept-scale, which explains how to use this section.1. Maximum value and minimum valueBefore introducing the scale, we introduce two functions that appear together with the scale bar, and also appear in the "3rd chapter". D3.max () D3.min () These two functions are used to find the maximum and

The basic idea of the scale space method is to introduce a parameter which is regarded as the scale in the visual information processing model, obtain the visual processing information at different scales through the continuous change scale parameter, then synthesize the information to dig into the essence characteristic of the image. The

Run Effect chart The map scale is an indispensable element in the map. In the process of designing and developing the GIS software, how to draw the map scale is a problem that needs to be solved seriously. There are several issues to be addressed in the process: 1. What tools are used? 2. How do different types of map scales be plotted separately? 3. How to control the drawing accuracy of map

The basic idea of the scale space method is:The visual information processing model is used to introduce the number of workers to be regarded as a scale, and obtain the visual processing information at different scales through the continuous change scale of workers, then, the information is integrated to deeply explore the essential features of the image. The

1.Scale Space of images The scale space expression of an image refers to the description of the image at all scales, because many processing operators in the scale space have a high degree of similarity with the sensory region profiles recorded in the outermost layers of the retina and visual cortex of mammals, the scale
