Flames that might appear on the side of a hot rod or similar. Made in Inkscape with some fairly simple curves, inset and outset shadows made manually by duplicating the base layer and moving slightly then using the path -> difference tool, a few layers with gradients to make the yellow glows, and finally a mask to make the left side a soft edge. Drawn for a friend to overlay behind a surfer in an action photo.<br/>熱棒火焰<br/>fire、Flames、hot rod、shadow<br/>火、火焰、熱棒、陰影<br/>資料來源：openclipart ( https://openclipart.org/ )
