php - 如何在 php 或 javascript 上扫描图像？

Question

我不知道有没有可能？

我有一个 php 项目，我们可以在 php 或 javascript 上或...通过扫描仪扫描图像，有什么办法吗？

Answer 1

假设扫描器连接到执行 PHP 的服务器:

目前有一些很好的解决方案，利用开源的SANE扫描软件通过PHP扫描图像:

SCANPHP

A PHP Lightweight Scanning GUI which makes use of the Open Source SANE Scanning software. The PHP GUI can be installed on any Web Server as long as PHP can be run. PHP calls the scanimage command in order to provide the scan. Post scanning, the image is piped "|" to gocr / pnmtojpeg in order to provide the acquired file.

PHPSANE

phpSANE is a web-based frontend for SANE written in HTML/PHP so you can scan with your web-browser. It also supports OCR.

一个代码示例是:

exec("scanimage --mode Gray --resolution 150 | pnmtojpeg > /tmp/image.jpg");

可以引用SANE Project Homepage有关可用选项、安装步骤等的更多信息。
