sbgnrender 1.0.0a9

A SBGN rendering library

SBGNRender Python library

This library is using Selenium to control ChromeDriver, to run a JS website rendering SBGN (based on Newt)

To install it, the simplest way is via PyPI :

sudo pip3 install sbgnrender

After installing the library, usage is the following :

from sbgnrender import renderSBGN

renderSBGN(
    input_file,  // Path as a string
    output_file, // Path as a string
    format,      // Format as a string : svg, png, jpg
    scale,       // Scale of the network (default 1 for svg, 3 for jpg/png)
    bg,          // Background color as HTML String (ex #fff for white), None for transparent (available for png/svg),
    max_width,   // Maximum width in pixels
    min_width,   // Minimum width in pixels
    quality,     // Quality (available for jpg),
    layout,      // Perform automatic layout
    verbose      // True | False
)

This library depends on ChromeDriver, which can be installed on ubuntu/debian systems with

sudo apt install chromium-chromedriver

On Ubuntu 19.x and later, chromium installation is using snap package manager, which causes a problem while writing and accessing temporary files. The current workaround is to change chromium temporary directory permissions with :

sudo chmod 711 /tmp/snap.chromium

This is just a temporary which you will have to do at startup (after having run chrome at least once) everytime. If somebody knows a trick, contributions are welcome
