The entire OpenCV library is already inside this package (`opencv.js` and `opencv.wasm`).\n\nThis module has zero dependencies.\n\n## Examples\n\n| Code | Input | Output |\n|---|---|---|\n| [dilation.js](https://github.com/echamudi/opencv-wasm/blob/master/examples/dilation.js) (node)|  |  |\n| [templateMatching.js](https://github.com/echamudi/opencv-wasm/blob/master/examples/templateMatching.js) (node) | source:

 |  |\n\n## Installation\n\n### node\n\n```\nnpm install opencv-wasm\n```\nCode example:\n```js\nconst { cv, cvTranslateError } = require('opencv-wasm');\n\nlet mat = cv.matFromArray(2, 3, cv.CV_8UC1, [1, 2, 3, 4, 5, 6]);\nconsole.log('cols =', mat.cols, '; rows =', mat.rows);\nconsole.log(mat.data8S);\n\ncv.transpose(mat, mat);\nconsole.log('cols =', mat.cols, '; rows =', mat.rows);\nconsole.log(mat.data8S);\n\n/*\ncols = 3 ; rows = 2\nInt8Array(6) [ 1, 2, 3, 4, 5, 6 ]\ncols = 2 ; rows = 3\nInt8Array(6) [ 1, 4, 2, 5, 3, 6 ]\n*/\n```\n\n### deno\n\n```ts\nimport { cv, cvTranslateError } from 'https://deno.land/x/opencv@v4.3.0-10/mod.ts';\n// Change the @ with the latest or any version you desire.\n// Check the available versions here: https://deno.land/x/opencv.\n```\nCode example:\n```ts\nimport { cv, cvTranslateError } from 'https://deno.land/x/opencv@v4.3.0-10/mod.ts';\n\nlet mat = cv.matFromArray(2, 3, cv.CV_8UC1, [1, 2, 3, 4, 5, 6]);\nconsole.log('cols =', mat.cols, '; rows =', mat.rows);\nconsole.log(mat.data8S);\n\ncv.transpose(mat, mat);\nconsole.log('cols =', mat.cols, '; rows =', mat.rows);\nconsole.log(mat.data8S);\n\n/*\ncols = 3 ; rows = 2\nInt8Array(6) [ 1, 2, 3, 4, 5, 6 ]\ncols = 2 ; rows = 3\nInt8Array(6) [ 1, 4, 2, 5, 3, 6 ]\n*/\n```\n\n## Usage\n\nBecause this module is using the same code as the official OpenCV.js for the web, you can use the same documentation at the web: https://docs.opencv.org/4.3.0/d5/d10/tutorial_js_root.html\n\nThere are some minor initialization changes, because this module will be loaded synchronously instead of the OpenCV's default (asynchronously). \n\nYou can check the files inside [examples](https://github.com/echamudi/opencv-wasm/tree/master/examples) folder as reference on how to initialize, loading images, and saving images.\n\n## Error Handling\n\nBy default, mistakes in code will produce error code. You can use the following snippet to translate the error code into meaningful statement from OpenCV.\n\n```js\nconst { cv, cvTranslateError } = require('opencv-wasm');\n\ntry {\n // Your OpenCV code\n} catch (err) {\n console.log(cvTranslateError(cv, err));\n}\n```\n\n## Versioning\n\nThis npm module uses the following versioning number:\n```\n-\n```\nFor Example\n```\n4.3.0-9\nOpenCV version 4.3.0\nOpenCV-Wasm Module version 9\n```\n\n## Development\n\n### Building\n\nRun the following script on macOS or Linux (tested on Ubuntu). You need docker on the system.\n\n```\nnpm install\n(cd ./utils && sh ./build.sh)\n(cd utils && node generateCvProps.js)\n```\n\n### Testing\n\nAfter completing the build script, you can run the test provided by OpenCV, and the test from this repo.\n\n```sh\n# OpenCV's test\n(cd ./build_wasm_test/bin && npm install)\n(cd ./build_wasm_test/bin && node tests.js)\n\n# This repo's test\nnpm test\n```\n\n## Authors\n\n* **Ezzat Chamudi** - [echamudi](https://github.com/echamudi)\n\nSee also the list of [contributors](https://github.com/echamudi/opencv-wasm/graphs/contributors) who participated in this project.\n\n## License\n\nCopyright © 2020 [Ezzat Chamudi](https://github.com/echamudi) and [OpenCV-Wasm Project Authors](https://github.com/echamudi/opencv-wasm/graphs/contributors)\n\nOpenCV-Wasm code is licensed under [BSD-3-Clause](https://opensource.org/licenses/BSD-3-Clause).
