Save SVG file to new one:

SVG Text Editing

  • This is the hardest task, as it is very demanding and tricky
  • SVG file has many features but we need only d="m ...  lines
  • Also the polylines can be encoded in many ways, absolute or relative coords 
  • There can be also e-number forms which u may write as zero values 0

Source SVG:

After filtering:

Remove the Z " from end of each line, as well as d="m from beginnings.

Use FIND to count all L letters, turn on wordwrap to see all lines at once.

Now you must comprehend coords system:

  • The first 2 coords after M are basepoints, after that are relative offsets;
  • If you find L-l block, the coords are absolute, not relative;
  • You must insert letter **a **before each absolute pair;
  • The last pair in one in L-l block must be preceded by** r **letter, which resets to rel. coords again;
  • Remove all L letters when done;
  • Also replace "," with " " (commas with spaces).

In Small Basic:

  • You may use **DWV062 **for all next Small Basic imports;
  • After first import you may encounter many issues, as displacing and missing parts;
  • Set fill to transparent for better seeing results;
  • You will obtain this at first import.

Now you can modify colors and add effects.

Use delay 2222 for better understanding parts ordering.

Final result:

As final part you return to notepad++ and replace lineends to "`" sign.

After that, select all line and paste to Small Basic instead of File.GetContents

Addendum

You can use LDImage.LoadSVG(fileName), but it gives u a BMP output, not as shapes as shown above!
