👷 Build images with images

👷 Build images with images.

About

Tiler is a tool to create an image using all kinds of other smaller images (tiles). It is different from other mosaic tools since it can adapt to tiles with multiple shapes and sizes (i.e. not limited to squares).

An image can be built out of circles, lines, waves, cross stitches, legos, minecraft blocks, paper clips, letters, ... The possibilities are endless!

Installation

• Clone the repo: git clone https://github.com/nuno-faria/tiler.git;
• Install Python 3;
• Install pip (optional, to install the dependencies);
• Install dependencies: pip install -r requirements.txt

Usage

• Make a folder with the tiles (and only the tiles) to build the image;
  • The script gen_tiles.py can help in this task; it builds tiles with multiple colors based on the source tile (note: its recommended for the source file to have an RGB color of (240,240,240)). It is used as python gen_tiles.py path/to/image and creates a folder with a 'gen_' prefix in the same path as the base image.
• Run python tiler.py path/to/image path/to/tiles_folder/.

Configuration

All configurations can be changed in the conf.py file.

gen_tiles.py

• DEPTH - number of divisions in each color channel (ex: DEPTH = 4 -> 4 * 4 * 4 = 64 colors);
• ROTATIONS - list of rotations, in degrees, to apply over the original image (ex: [0, 90]).

tiler.py

• COLOR_DEPTH - number of divisions in each color channel (ex: COLOR_DEPTH = 4 -> 4 * 4 * 4 = 64 colors);
• IMAGE_SCALE - scale to apply to the image to tile (1 = default scale);
• RESIZING_SCALES - scale to apply to each tile (ex: [1, 0.75, 0.5, 0.25]);
• PIXEL_SHIFT - number of pixels shifted to create each box (ex: (5,5)); if None, shift will be the same as the tile dimension);
• OVERLAP_TILES - if tiles can overlap;
• RENDER - render image as its being built;
• POOL_SIZE - multiprocessing pool size;
• IMAGE_TO_TILE - image to tile (ignored if passed as the 1st arg);
• TILES_FOLDER - folder with tiles (ignored if passed as the 2nd arg);
• OUT - result image filename.

Config details for example output

Hello there and thanks for this awesome repo.

I am trying to manipulate the config parameters to get the awesome results in the readme ,but I can not make that happen.

Can you provide details config for each example ?

Sorry,you've spelt the word wrong.

Requesting permission to use some of your Tiles

@nuno-faria I am creating my own tiler and while i have not copied any of your code I have used some of your tiles but I wanted to get permission to do this before I continue on. If you say no i will remove the tiles I have copied so far. Thanks

Feature : Use vector image or input and output

Hi !
I find this project very attractive artisticly-wise, and I was wondering how big of a deal it would be to use SVGs images as an input in order to have scalable vector graphics at the output.

I know it might sound far-fetched, but are you (or can you) consider it ?

Thanks for your great work,

Cheers !

what should i put under tiles_paths

It takes a long time

I'm working with a 960 * 960 pixel image with circle_100 tile, it takes me about 20 mins. Is it because of the poor performance of my computer? Can I accelerate it with GPU? Looking forward your reply.

only work with 'at' tiles

second command generate empty out.png file, why?

Creating tiles with multiple arbitrary Objects?

Just wondering whether the algorithm would still work if you use let's say paperclips and minecraft blocks, that would give a lot more creative freedom, but not sure how the algorithm would hold up with many different shapes.

Can I batch convert?

I want to batch convert several images instead of selecting them one by one, and I don't know how to do it.

Hello

I am following the usage instructions, but get some trouble.

Thanks @nuno-faria，I got it

Here is the solution

python tiler.py ~/Downloads/tmp/cake.png tiles/circles/gen_circle_100/

I though the first parameter is my input image, and second parameter as output directory. But it is not, the second parameter is also input, as basic element.

Tiler should pre-allocate array before loading tiles

If working on a large image it's possible you won't have enough ram to load, but you have to find this out after the tiles load (which can take a bit). Maybe allocate the buffer first to ensure we have space?
