Hello everyone, I am a red panda ❤
I have to say that the weather is really nice today.
neither cold nor hot~
The wind is blowing nicely~
The only downside is that I can't go out to play~ (woo woo wailing as a worker)

How to convert an ordinary emoji into pixel style?
Next, I will use python to create a pixel wind with you~
Introduction to Tiler
Tiler, which means bricklayer, is to use various small elements as "tiles" to build a big picture [1].
Address: https://github.com/nuno-faria/tiler
The project presets a lot of "tiles":
There are LEGOs, plus signs, circles, @ signs, hearts, multipliers, wavy lines, horizontal and vertical bars, various grids from Minecraft, and paper clips.
In this article, I prefer to call them " pixel tiles ".
The project has already received 4.6k stars on GitHub
Looking at the sample image, the pixel-style emoji mentioned at the beginning of this article should also be implemented.
Without further ado, install it first.
Clone and download the project, and then install the dependencies in requirements.txt.
git clone https://github.com/nuno-faria/tiler.git
pip install -r requirements.txt
The specific operation is shown in the following figure
C: \Users\Administrator>cd tiler
C:\[Users\Administrator|ti1er>pip install -r requirements.txt
Convert pixmap
Now demonstrate how to use Tiler to convert ordinary emoticons into pixel style.
After the previous operations, you can see the downloaded files and configurations locally.
Among them, the folder images contains project sample images, the folder tiles contains the tile directory, and the conf.py contains configuration files.
C:\Users\Administrator\tiler
I added a to-be-converted image - 333.png, but it doesn't matter if I put it in other directories, I just need to specify it in the next step.
In addition to the image to be converted, you also need to select a pixel tile. Only the line is suitable for the built-in pixel tile. We will use it to demonstrate first.
Among them, gen_line_h is placed in a horizontal line segment diagram.
To generate a pixmap, execute the following commands in the tiler directory:
python tiler.py ./images/333.png ./tiles/lines/gen_line_h/
During the execution process, there is a progress bar reminder. The image to be converted is small, and it is completed in a few seconds.
At this point in the tiler directory, a new image has been generated - out.png.
What about the Convert Pixel effect?
Achieved, but not fully realized, and a little bit of soul - not enough pixels.
customize
I'm guessing it's an issue with pixel tiles, the image above uses rectangular tiles.
But in the built-in directory, no square was found, so we need to customize the pixel block.
If you want a better pixel wind conversion effect, it is best to adjust the parameter configuration .
Let's talk about custom pixel blocks first.
custom pattern
First, create a new folder square2 in the directory tiles.
Put a custom pixel tile in it, I prepared a square (50x50 pixels).
The suggested color[2] is #F0F0F0.
C:\Users\Administrator\tiler\tiles\square2
Just having one tile is not enough, you need to use the script gen_tiles.py to generate a series of multi-color tiles.
custom parameters
Parameters can also be customized before generating pixel tiles.
By changing the code in conf.py, I adjusted values like DEPTH.
- DEPTH: The number of partitions for each color, the default value is 4.
- COLOR_DEPTH: The number of colors the image contains, the default value is 32.
#GEN TILES CONFS
#number of divisions per color R,Gand B)#DEPTH =4 ->4*4*4=64 colors
DEPTH -6
# list of rotations, in degrees, to apply over the original imageROTATIONS - [e]
#############################
#TILER CONFS
#number of colors per imageCOLOR_DEPTH = 64
#tiles scales(1 = default resolution)RESIZING_SCALES -[0.5，0.4，0.3,0.2， 0.1]
# number of pixels shifted to create each box (tuple with (x,y))
# if value is None，shift will be done accordingly to tiles dimensions#PIXEL_SHIFT =(5,5)
PIXEL_SHIFT - None
#if tiles can overlapOVERLAP_TILES = False
#render image as its being builtRENDER = False
The author has annotated each configuration parameter in conf.py, and you can adjust it yourself when you use it.
custom effects
Next generate new pixel tiles.
Execute the command in the tiler directory:
Open the folder gen_square2, the pixel tiles of various colors have been generated.
The next step is to recreate the pixmap using the new tiles:
python tiler.py ./images/333.png ./tiles/square2/gen_square2/
Isn't it so simple! ! !
