install\r\n\r\n`npm install @rgba-image/lanczos`\r\n\r\n## usage\r\n\r\nResize the source image to fit in the destination image:\r\n\r\n```js\r\nconst { lanczos } = require( '@rgba-image/lanczos' )\r\n\r\nlanczos( source, dest )\r\n```\r\n\r\nResize from a source region to a location on the destination image:\r\n\r\n```js\r\nconst sourceX = 10\r\nconst sourceY = 20\r\nconst sourceWidth = 50\r\nconst sourceHeight = 100\r\nconst destX = 30\r\nconst destY = 40\r\nconst destWidth = 150\r\nconst destHeight = 300\r\n\r\nlanczos( source, dest, sourceX, sourceY, sourceWidth, sourceHeight,

uses lanczos3 resampling. You can also use lanczos2, usage is\r\nexactly the same, but you import lanczos2 instead of lanczos:\r\n\r\n```js\r\nconst { lanczos2 } = require( '@rgba-image/lanczos' )\r\n```\r\n\r\n## License\r\n\r\nMIT License\r\n\r\nCopyright (c) 2018 Nik Coughlin\r\n\r\nPermission is hereby granted, free of charge, to any person obtaining a copy\r\nof this software and associated documentation files (the \"Software\"), to deal\r\nin the Software without restriction, including without limitation the rights\r\nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell\r\ncopies of the Software, and to permit persons to whom the Software is\r\nfurnished to do so, subject to the following conditions:\r\n\r\nThe above copyright notice and this permission notice shall be included in all\r\ncopies or substantial portions of the Software.\r\n\r\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR\r\nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,\r\nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
