Feng Baobao, how to draw pictures and texts with pixelation?
The following are the steps for general pixel-based drawing (although there are no steps specifically for Feng Baobao's pixel-based drawing, they can be used universally): ##1. Drawing software recommendations 1. **Photoshop** - This was a powerful drawing software. It drew a bit map, and after zooming in, it would show a pixel-style colored grid. It had powerful post-editing functions and could also be used to create pixel-style animations. 2. **AI（Adobe Illustrator）** - It was a drawing software. The drawing was not limited by the size of the canvas, and zooming would not affect the clarity. The [Rectangle Grids Tool] can be used to draw pixelated wind. It is suitable for drawing simple pixelated icons, pixelated cartoon characters, etc., but it cannot be used for animation effects. 3. **Aseprite** - A software that focused on the creation of pixelated paintings. The interface was simple and easy to use. There was a tool specifically for curve and diagonal adjustment, which could greatly reduce the appearance of jagged edges. It could also be used to create animations. It could be purchased on Steam (no Chinese version available). ##2. Basic settings for drawing a pixelated picture with PS 1. ** New Canvas ** - Create a new canvas (shortcut key: Ctrl-N) and set the canvas size to the unit of measurement: Pieces. In addition, there was another important setting: [edit] → [preferences](shortcut key: Ctrl-K). Change the image's subspace to "adjacent (retain hard edges)", and then you could start painting. 2. ** Setting up the brush and pen ** - Choose the pencil tool and set the brush size to 1 px, Opacity to 100%, Pressure to Off, and Smoothing to 0%. In this way, any line drawn with a pencil would be a 1-pel line. 3. ** Paintbucket Tool ** - When you need to paint a large area, you can use the paint bucket tool. Remember to uncheck the [Anti-sawtooth] option and set the tolerance to 0. This way, the color that you fill will not contain sawtooth. ##3. Drawing Techniques of Pixel-based Drawing 1. ** Canvas size ** - The size of the canvas depended on how much detail he wanted to draw. For beginners, it is recommended to start with a small canvas, such as 50x50 or smaller. An object had to be drawn with as little as possible to ensure that it was recognizable enough. Even if the resolution was low, it could still show a rich picture. 2. ** Clean Lines ** - First, he drew a sketch, then based on the sketch, he drew a 1-pel line sketch. When drawing the first round of the line drawing, focus on the lines and shapes first. After the model is completed, clean up the excess dots and irregular jagged lines. 3. ** Control the number of colors ** - When you first start drawing, it is recommended to control the number of colors. Because the canvas was small, too many colors would easily get mixed up. He could practice using large blocks of color first. When drawing an object, after filling in the intrinsic color, find the intersection between light and dark, first draw the color of the dark part, then draw the color of the light part. 4. ** Lossless Enlarging of Pixel-Based Painting ** - He selected a low-resolution layer, right-clicked, and turned the image into a smart object.[Editor] → [Free Transform](shortcut key: Control +T). This way, the image would not become blurry even if it was enlarged. 5. ** The Dithering Technique of Pixel-Based Painting ** - Dithering was a common technique in the creation of pixelated paintings. It could make the color transition more natural, express the texture and texture of the object, and increase the level. Different levels of shaking would reveal different details. When you first started drawing, you could start with simple levels of shaking, mainly used in large areas or large scenes. After mastering simple pixelated painting, he could try to challenge different levels of dithering. As for Feng Baobao's pixelated drawing, he first had to identify Feng Baobao's character characteristics, such as hairstyle, clothing, expressions, and other elements. Then, he would create it according to the above pixelated drawing method. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Scripting, creating pixelation
One way to create a pixelated map with a script was to first take out the rmb value of each pixelated point in a pixelated map, then use the script to operate excel and set the rmb value as the background color of the cell. This process mainly involved two points: one was to use Python to do image processing, which would use the Image module; the second was to use Python to operate excel. There were three main methods to operate excel with Python on the Internet, namely xlrd, xlwd, xlutils, pyExcelerator, and pywin32. The first two had better support for simple excel operations and were cross-platform, while Pywin32 was equivalent to excel's interface. It had rich operations, but it could only be done under the window and excel was installed. In this application, because the background color needed to be set according to different rmb values (the first two can only set common color values), so Pywin32 was selected. It should be noted that when setting the color, the rmb must be converted to hex, and the order of the rmb values must be reversed first. Otherwise, the color value set is opposite to the rmb value passed in. Through these two libraries, one could automatically draw a picture in excel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Led matrix and pixelation
The LED matrix was a layout consisting of multiple LED light sources. These LED lights could be controlled independently to achieve different lighting effects or display functions. Taking the car field as an example, the matrix LED headlights of the Buick Regal GS consisted of 105 LED light sources, forming 84 independently controllable lighting zones. This was an application of the LED matrix in lighting. Pieces were used to describe the resolution of the LED beads in the matrix. Like Porsche's newly announced "HD matrix LED flashlight" headlights technology, each light group was composed of 16384 LED lamp beads, and the two headlights had a total of 65536-pixel-matrix light source. Compared to the existing headlights that provided 84-pixel-matrix light sources, the light source projection accuracy of the new product was improved by several orders of magnitude. In the field of LED screens, such as transparent LED screens, there was also an LED matrix. The screen was assembled from a series of individual LED dots in a matrix pattern, and each dot emitted light to present the overall color. This meant that whether it was in lighting or display devices, the LED matrix and the concept of the pixelated were related. The pixelated was an indicator of the degree of detail of the LED beads in the matrix, and the matrix was the layout of many LED beads. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What is the printing pixelation setting?
Different types of printed matter had different requirements for the pixelation settings: 1. ** Four-color printing manuscript **: The basic resolution requirement is 300dpi or above. Some high-end fashion magazines require a resolution of more than 1000. 2. ** Black-and-white manuscript **: The resolution requirement is relatively low, but it should be around 200dpi. 3. ** Ink jet printing electronic file **: The resolution varies with the size. Generally, the media used by the ink-jet printer is 30 - 45dpi. For large anti-aircraft gun advertisements, the resolution can be appropriately reduced, or even less than 10dpi. The photo output image is small, and the resolution is generally not lower than 72dpi. The recommended resolution is 120dpi. 4. ** Digital printing (commonly used for small batches of picture albums, posters, flyers, etc.)**: The recommended resolution is 300dpi, and the minimum is 200dpi. 5. ** newspaper printing **: The scanning resolution is 125 - 170dpi. For printed images, the resolution is set to 1.5 to 2 times the screen line (85lpi for newspaper printing). 6. ** Magazine/promotional material printing **: Scanning resolution of 300dpi (133 or 150dpi for magazine printing). 7. ** High-quality book printing **: The scanning resolution is 350 - 400dpi (175 - 200lpi for book printing). 8. ** Wide-format printing (such as posters and other large-format images that can be seen from afar)**: The scanning resolution used is 75 - 150dpi. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Comparing the pixelation of the iPhone with the iPhone
There were many different types of cell phones with different pixelation. For example, the 808 had 41 million pixelation, the Lumia 1020 had 41 million pixelation, and the N9 had 8 million pixelation. There was also a cell phone with 13 million pixelation and two 2 million pixelation camera modules. The iPhone 4S, the iPhone 6, and the iPhone 6 Plus all used 8 MP cameras, while the iPhone 6S and the iPhone 12 series used 12 MP cameras. It can be seen that there are models with higher resolution than Apple phones, such as the nokia808 and nokia1020, and there are also models with lower resolution than Apple phones, such as the nokiaN9. The resolution of the two models varies. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
