Article Introduction：Amap API document analysis: How to implement the vector layer of the map in PHP Map applications have become an indispensable part of our daily lives. When developing map applications, it is very important to organically combine maps with your own business needs. In map applications, vector layers are a common and very practical way to display maps. This article will introduce how to use the Amap API to implement the vector layer function of the map in PHP. Before we begin, we need to understand the basic usage of the Amap API

Article Introduction：What does vector graphics mean? A vector image is an image described using geometric figures, which are represented by mathematical formulas rather than a collection of pixels. In computer graphics, vector graphics are widely used in graphic design, CAD, map production, chart drawing and other fields. In contrast, bitmap images are composed of pixels, and the number of pixels determines the resolution of the image. Unlike bitmap images, vector images use geometric shapes such as line segments, curves, and points to describe images. Due to the use of mathematical formulas, vector images can be enlarged infinitely without distortion; while bitmap images

Article Introduction：Vector images and bitmaps are two common image file formats, and they have different characteristics and applications in digital image processing. This article will introduce the differences and characteristics of vector graphics and bitmaps. First of all, a vector image is an image composed of a series of geometric shapes and paths. The biggest feature of vector graphics is that each element in the image is represented by a mathematical formula instead of being described by a grid of pixels. Vector graphics can be scaled losslessly, maintaining image clarity and quality at any resolution. Common file formats for vector graphics include EPS, AI, S

Article Introduction：Is the vector image png or jpg? In the field of image processing, we often hear the terms vector graphics and bitmaps. They represent two different image representation methods, with their own characteristics and uses. Among these two representation methods, generally speaking, vector images are often saved in SVG, AI, EPS and other file formats, while bitmaps are often saved in png, jpg, bmp and other formats. So to answer the question in the title, vector images can be png or jpg, but they can also be in other formats. The difference between vector graphics and bitmaps is their

Article Introduction：Vector graphics are graphics described based on mathematical formulas. They consist of a series of points and line segments. Through the combination and arrangement of these points and line segments, an image is formed. Compared with bitmaps, vector images have many advantages, such as lossless enlargement and reduction, small file size, and flexible editing. Therefore, vector graphics are widely used in many design fields, such as illustration, logo design, print production, etc. Well, the first issue in making vector graphics is choosing the right software. There are many professional vector graphics production software on the market today.

Article Introduction：Vector images are not in png format; vector images are object-oriented images or drawing images, which are drawn based on geometric characteristics. The formats of vector images include svg, cdr, win, emf formats, etc., while png format refers to portable network graphics. , is a bitmap format that uses a lossless compression algorithm.

Article Introduction：Introduction to how to use Golang to convert pictures into SVG vector graphics: In the field of image processing, SVG (ScalableVectorGraphics) has become a popular format, which can store and display vector graphics. This article will introduce how to use the Golang programming language to convert images into SVG vector graphics. SVG conversion principle: The principle of converting pictures into SVG vector graphics is to convert pixel points into paths, and use paths to describe the outline of the image. During the conversion process we will

Paper idea: This paper proposes a novel end-to-end process for building online long-distance vectorized high-precision (HD) maps using vehicle-mounted camera sensors. Vectorized representations of high-precision maps use polylines and polygons to represent map features, which are widely used by downstream tasks. However, previous solutions designed with reference to dynamic target detection ignored the linear map

Article Introduction：CorelDRAW is a very easy-to-use vector design software that supports the conversion of images between vector graphics and bitmaps. So how do you remove the background in a bitmap and turn the image into a vector image? Trace through the outline of a bitmap image, with the option to remove background color as you trace, converting the bitmap into a fully editable and fully scalable vector graphic. Let’s take a look at the details! The specific operations are as follows: 1. Open the CorelDRAW software and import the bitmap image that needs to be processed. 2. Select [Bitmap] > [Trace Bitmap] > [Outline Tracing] > [Line Drawing] in the top menu bar. 3. In the pop-up dialog box, set parameters according to personal needs. Make sure the Remove Background option is checked.

Article Introduction：CorelDRAW is a very easy-to-use vector design software. We can directly use the software to design vector graphics. There are many new friends who can’t tell what is a vector image and what is a bitmap, and will even draw an equal sign between them. Today I will talk about the differences and characteristics between them to make everyone better understanding of using the software. The specific differences are as follows: 1. The constituent units of bitmaps and vector images are different. Bitmaps are composed of pixels. The more pixels there are, the higher the space occupied and the definition. But bitmaps have a fixed size and will be blurry when enlarged. Vector graphics use mathematical formulas to describe graphics and can be enlarged infinitely without distortion. Continuously enlarge the picture to clearly see the blur. 2) Vector images are composed of mathematical formulas and can be enlarged or reduced infinitely without causing

Article Introduction：Previously we shared how to remove the background of a simple picture and extract a vector image in CorelDRAW. Just use automatic color selection and remove it with one click. But for pictures with complex backgrounds, this method may not be suitable because removing the background will also affect the part of the image that needs to be retained. So how should we operate on pictures with complex backgrounds? Let’s find out together! The specific operations are as follows: Open the CorelDRAW software and import the pictures that need to be processed. Click the [Draw Bitmap]-[Outline Draw]-[Line Drawing] option in the menu, and you can also try other drawing methods to retain more details and extract more complex vector graphics. Doing so converts the image into a vector format for further editing and adjustment

Article Introduction：CorelDRAW is a very easy-to-use graphic design software that can draw vector images and bitmaps. Bitmaps are composed of pixels and will be distorted and blurred after being enlarged to a certain extent, while vector images will not. Users can also use software to convert images between the two formats. Many friends said that there is no response when using CorelDRAW software to convert bitmaps into vector images. What is going on? Let’s take a look. The specific steps are as follows: There are two reasons why a bitmap cannot be converted to a vector image: the bitmap is too large or the resolution is too low. The first method is easy to solve by re-saving and compressing it. So how to change the resolution? 1. Open the CorelDRAW software, import the image, click [Bitmap]-[Resample] above
