The picture that needs to be made is the part on the left in the attachment. Used to apply for system hotspots The target requires about one screen 1. First download the picture and convert it into bmp format if you need to crop some parts. As shown in the bmp in the attachment 2. Open the bmp file in b2a Note: It is more convenient to change the background color to black if possible. There are two tips in the process of transferring pictures: 1 is the choice of color The main color of my picture is red, and the color fades in some places. So I chose low brightness white, low brightness red and high and low brightness black. Some people may ask why not choose highlight red It will indeed be much brighter with the highlight red color However, people who often draw will find that the use of color blocks is very limited. For general Asciier, I recommend using low-bright colors for color blocks. 2 is x rate, y rate and dx, dy x rate and y rate are proportions, dx dy is translation The original image is smaller I chose x rate and y rate as 3 After transferring it, I found that the image was larger than one screen. So it is more appropriate to change the size of the picture to 2.5. Here I think it would be better to move the whole picture upward so that the color blocks can be used more easily. So I entered 3 on dy, which seems to be this number. I can’t remember the specific value. The effect is as follows Both of the above techniques can be adjusted by selecting different parameters. The goal is to make the image as close as possible to the original The picture below is the effect of using different dy on the globe part of the original picture. You can see that the bottom of the picture above is smooth and easier to make, but the triangle on the bottom is very strange. 3. Modify the transferred image As you can see from the picture above, it is very different from the final work. Further modifications include Change background to black Modify some color blocks, etc. This is a long and arduous process It only took me five minutes to transfer the picture The later modifications took more than an hour. In addition, there are some other techniques in processing this picture. I tried to use color blocks to draw the two apertures near the numbers, but the continuity was not very good. So it was changed to a straight line because the change of angle is also very difficult to handle. Finally changed to dot final result . ' '. . ' ' . clear ' : magnificent ' , big .

Summary: Using b2a to make a good work still requires certain basic knowledge and skills of asciier. Not just turning any picture into a good work using b2a Later modifications are far more important than the transfer itself extreme agent Source: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 10.100.116.44] Modification: lzl modified this article at 08:25:11 on October 20 [FROM: 10.100.116.44]
