How to generate SVGs

Use the following URL format:

/generate_svg?font_size=[integer]&text=[string]&text_length=[integer]&fill_color=[color]&text_color=[color]&shape=[circle/square/square_rounded/diamond]

Example: /generate_svg?font_size=30&text=Hello+World&text_length=5&fill_color=%23ff0000&text_color=%23ffffff&shape=circle

This request would generate an SVG image with the text "HW" (shortened from "Hello World") in a font size of 30, with a red fill color and white text color, and a circle shape.

text: The text to be displayed on the SVG. Mandatory.
shape: The shape to use (circle/square/square_rounded/diamond). Default to circle.
font_size: The size of the text in pixels. Default to 30 px.
text_length: The maximum length of the text. Defines how many characters the image will contain at most, but it is the algorithm that ultimately decides how many letters to put. Default to 3.
fill_color: The color of the shape. If not provided, a random color will be generated.
text_color: The color of the text. If not provided, a random color will be generated that has sufficient contrast with the fill color.

If you don't specify a fill_color or text_color, the script will generate a random one that has sufficient contrast with the other color. If you omit both colors, the script will generate two random colors with enough contrast.
