Just for fun... watermark graphics! The steps are:
1. Choose an image, probably no more than 20x20 pixels 2. Use an image library to convert each pixel into a table cell, as shown in the script.
I used they Python "pillow" library for step 2. This library allows you to iterate over each pixel, grab the RGB value, and generate table cells. You can use the width/height attributes of each cell to size the watermark.
Be careful, because Pinescript has a maximum character limit around 60,000 or so, and this script will reach that limit quickly. You also run into some limitation on table size, I think. That's why I suggest using no more than a 20x20 image.
Pictured in this chart is a legendary trader... message me if you would like to commission your own watermark.
