# brickmos
**brick**-**mos**aic
This is a simple tool for converting images to Lego mosaics such that their
parts can be ordered quite easily from bricklink (https://www.bricklink.com/).
I wrote this for myself for a birthday present I worked on, but wanted to leave
it here for others to re-use or as inspiration.
(ltr: original image, pixelated image with original color, image with colors
mapped to given Lego colors; [image source](https://www.vincenthie.com/gallery/disney/ironmanportrait))
## Motivation & alternatives
This is a rather simple script which worked well for me, as I went back and
forth between my image editing tool and modifying the color pallet. I really
like this continuous process of shaping the result while keeping colors/brick
types and their prices under control. I even ended up replacing one 1x1 plate
with a 1x1 tile, since the respective color was too expensive on bricklink.
Furthermore, I was only interested in full 1x1 mosaics, similar to the Lego
mosaic art product line. I also ended up buying the frame parts used for the
Lego art frame, as it is extendable and easily wall-mountable (see [here](https://www.lego.com/de-de/campaigns/art/)).
However, if you are more interested in a GUI application, different workflow or
automatically chosen larger than 1x1 pixels, you may want to have a look at the
following alternatives (if I forgot an alternative here, let me know):
- Bricklink studio (full-blown brick set designer with a mosaic feature, (see
[here](https://www.bricklink.com/v3/studio/download.page))
- PicToBrick (specifically made for brick mosaics, see [here](http://www.pictobrick.de/en/pictobrick.shtml))
## Quickstart
The following should get you started.
### Dependencies
Main dependencies are:
- Python (I used python 3.8)
- `opencv-python` (the version I used is defined in _requirements.txt_)
If you run into problems missing `libGL.so`, install the following:
```bash
sudo apt update
sudo apt install libgl1-mesa-glx
```
### Installation
Install via PyPi
```bash
pip install brickmos --upgrade
```
### Process an image
Convert an image by invoking the script as follows:
`brickmos data/iron-man-portrait.jpg --output_directory="temp"`
Or alternatively clone this repo and run it directly:
`python run.py data/iron-man-portrait.jpg --output_directory="temp"`
Repeat the process while modifying the original image (change colors in areas
not working well, change colors overall, etc.) and limiting / extending the
colors (add useful ones, remove expensive ones) until you are satisfied with the
outcome (and price ;) ).
### Import parts to bricklink
1. Login at [https://www.bricklink.com/](https://www.bricklink.com/)
1. Go to __Want > Upload__ (see [here](https://www.bricklink.com/v2/wanted/upload.page))
1. Choose ___Upload BrickLink XML format___
1. Copy & paste (ctrl-a, ctrl-c, ctrl-v) the XML output of the tool into the window
1. _Proceed to verify items_ and add all to a wishlist (please double-check the
items, before ordering)
## Further information
Find some further definitions below.
### Parameters
Find a short explanation of the parameter arguments below.
#### Required arguments
- `--image_file, -i`: the path to the (original) image to process, can be a
_.jpg_ or _.png_ file
#### Optional arguments
- `--color_file`: the csv-file defining the brick-colors to be used (if not
given, colors.csv at script location is attempted), see format description
below
- `--output_directory, -o`: the directory the output image and BOM is written to
(default is current working directory)
- `--spares`: the number of spares to add per color/brick (in bricklink BOM),
just in case of loosing some bricks
- `--size`: the width/height of the image in 1x1 bricks (default is _48x48_ -
same as current Lego art)
- `--grid_cell`: the size of one cell in the helper grid (e.g.: _4x4_), the
helper grid is useful as a guide when finally placing the bricks, it can be
deactivated by specifying _none_
## Color definition
The set of available colors is defined by the csv-file (`--color_file`, see
above). The following information is required.
```text
rgb ; Bricklink Color Name ; Bricklink Color ID ; Bricklink Part ID
255,255,255 ; White ; 1 ; 3024
175,181,199 ; LightBluishGray ; 86 ; 3024
89,93,96 ; DarkBluishGray ; 85 ; 3024
33,33,33 ; Black ; 11 ; 3024
```
This is an example set of colors for a 4 'color' black & white picture using 1x1
plates. The example is already in expected format. The format requires a header
line and semicolons as column delimiters. The values used here should be aligned
with the definitions on bricklink for the export to work properly (see
[https://www.bricklink.com/catalogColors.asp](https://www.bricklink.com/catalogColors.asp)).
More details about each column:
- The first column is the RGB value of the corresponding color. There is no
official definition of these from Lego, thus, use something as close as
possible you can find. I picked the colors defined on the bricklink page.
- The second column is just a recognizable name for the color. Using the
bricklink name seems reasonable.
- The third column is the bricklink color ID (see page mentioned before). This
is important for the XML-export to function properly.
- The fourth column is the bricklink brick type ID. You can find these in
bricklinks database. Since the script only considers 1x1 parts, only these
should be used. The _3024_ from the example is the 1x1 plate (see [here](https://www.bricklink.com/v2/catalog/catalogitem.page?P=3024#T=C)).
Other options include, but are not limited to, 1x1 tiles (3070b, see [here](https://www.bricklink.com/v2/catalog/catalogitem.page?P=3070b#T=C))
or 1x1 plate round (4073, see [here](https://www.bricklink.com/v2/catalog/catalogitem.page?P=4073#T=C)).
Note that prices vary _a lot_ with color **AND** brick type. For my own mosaic
I used 1x1 plates, but replaced an expensive color with a much cheaper 1x1
tile.
