Node js resize image on the fly8/30/2023 ![]() ![]() So, with this article I want to do three things: And, if you're like me and still on your "learning algorithms" journey, this algorithmic solution may enrich your personal DP arsenal. ![]() Another point that drew my attention (as a creator of javascript-algorithms repo) was the fact that Dynamic Programming (DP) approach might be smoothly applied to solve it. There are many great articles written about the Seam Carving algorithm already, but I couldn't resist the temptation to explore this elegant, powerful, and yet simple algorithm on my own, and to write about my personal experience with it. lanczos3: Use a Lanczos kernel with a=3 (the default).There is an interactive version of this post available where you can upload and resize your custom images. lanczos2: Use a Lanczos kernel with a=2. nearest: Use nearest neighbour interpolation. attention: focus on the region with the highest luminance frequency, colour saturation and presence of skin tones. entropy: focus on the region with the highest Shannon entropy. The experimental strategy-based approach resizes so one dimension is at its target length then repeatedly ranks edge regions,ĭiscarding the edge with the lowest score based on the selected strategy. Some of these values are based on the object-position CSS property. sharp.strategy: cover only, dynamically crop using either the entropy or attention strategy. avity: north, northeast, east, southeast, south, southwest, west, northwest, center or centre. sharp.position: top, right top, right, right bottom, bottom, left bottom, left, left top. When using a fit of cover or contain, the default position is centre. Some of these values are based on the object-fit CSS property. outside: Preserving aspect ratio, resize the image to be as small as possible while ensuring its dimensions are greater than or equal to both those specified. inside: Preserving aspect ratio, resize the image to be as large as possible while ensuring its dimensions are less than or equal to both those specified. fill: Ignore the aspect ratio of the input and stretch to both provided dimensions. contain: Embed within both provided dimensions. cover: Crop to cover both provided dimensions (the default). When both a width and height are provided, the possible methods by which the image should fit these are: JSDoc Resize image to width, height or width x height. ![]()
