Programmed for extracting raw data (.txt files) from .svg files with a common pattern. This project contains sample.svg file and blank sample.txt file to make it easier for you to try it!

• To run this yourself, review requirements.md file and do the following in terminal:

cd <path of the project on your computer>

python main.py

• Note: requirements.txt do NOT need to be run as no libraries are required. If you do so, following error will occur...

ERROR: You must give at least one requirement to install (see "pip help install")

• Understand the output
• Understand the code
• Use cases

This program helped me with extracting raw data from .svg exported Gimp paths.

Output is pixels' x and y coordinates in this format:

    x, y in pixels 

    1240, 1099

    2975, 2834

    ...

• Note: The data HAVE TO begin with "C" and end with "/>" while having unwanted ' " ' at the end for this to work as intended

The program is written in Python 3.10

• The program opens your .svg file

def main():

    f = open("sample.svg", "r")

• For loop that goes over every line in your .svg file and does all the magic

    for line in f.readlines():

• l represents a line in the cycle, if its length is 0, program skips the line and move onto the next one

        l = line.split()
    
        if len(l) == 0:
            continue 

• The data we want start with "C", only after the "C" is found, program starts storing the data to lists

        if l[0] == "C":
            i = 1
            l = l[1:]
            
        if i == 0:
            continue

• Some unwanted elements ("/>" and '"') are present near the data we want, this removes them!

        if l[-1] == "/>":
            i = 0
            l = l[:-1]
            l[-1] = l[-1][:-1]

• Now "uninterupted" data is further split into x and y values, those are then appended to lists

        for j in range(0, len(l)):
            x, y = l[j].split(",") 

            pixels_x.append(x)
            pixels_y.append(y)

• The program opens .txt file as e where the extracted data will be stored and writes info about the contents of the file

    e = open("sample.txt", "w")
    e.write("# x, y in pixels")

• x and y values are then written into the text file in the format seen above

    for j in range(0, len(pixels_x)):
        e.write("%s %s\n" % (pixels_x[j], pixels_y[j]))
