colorbar
Add a colorbar to an image in milliseconds (faster than plt.imshow+plt.colorbar) 💨
colorbar achieves its speed by avoiding matplotlib and instead using numpy, pillow, cmap and pycairo!
🛠️ Install via: pip install colorbar (+ if pycairo causes trouble try conda install anaconda::pycairo)
Usage 💡
```python import numpy as np from colorbar import CBar
shape = (400, 800)
im = np.linspace(0, 1, shape[0] * shape[1]).reshape(*shape) # dummy image
cbar = CBar(cmap='gray', # see https://cmap-docs.readthedocs.io/en/latest/catalog/
vmin=im.min(), # pixels <= vmin become first color of cmap
vmax=im.max()) # pixels >= vmax become last color of cmap
imcbar = cbar.draw(im) # draw colorbar!
imcbar.show()
```
draw() returns a PIL.Image that is shown via show() and saved via save()
python
im_cbar.save('cbar.png')
Use cbar.save() instead of im=cbar.draw()+im.save() to save the image as a vector graphic
python
...
cbar.save('cbar.pdf', im) # .pdf, .svg, .ps or .eps
To customize the colorbar, draw() and save() take the arguments:
- vertical: If True, colorbar is vertical. Default: True
- pad: Added pixel rows on the colorbar-side of the image. Default: 0
- pad_color: Color-string of added pixels. Default: 'k'(=black)
- x: Position of the colorbar center relative to image in width-direction. Default: .9
- y: Position of the colorbar center relative to image in length-direction. Default: .5
- width: Size of the colorbar relative to image. Default: .05
- length: Size of the colorbar relative to image. Default: .8
- label: Label above the colorbar. Default: None
- ticks: List (e.g. [0, 1]) or dict (e.g. {0: 'low', 1: 'high'}) of ticks. Default: None
- fontsize: Fontsize of labels and ticks. Default: 20
- linecolor: Color of the lines and the font used to write labels and ticks. Default: w(=white)
- linewidth: Width of ticklines and outlines. Default: 2
- tick_len: Length of ticklines. Default: 2
Finally, if you want draw() to return a numpy array use asarray=True
python
im_cbar = cbar.draw(im, asarray=True)
to e.g. plot it with matplotlib via plt.imshow(im_cbar).
