在用户扫描过程中,可能会有新的扫描设备打开,也可能现有的扫描设备关闭,因此,有必要让用户随时知道可用的设备列表。其设计思路是:在选择更新设备后,调用sane_get_devices来获得可用的设备列表。实现时,为了允许用户在更新设备时进行其他操作,可将更新的操作放至一个新的线程中去实现。当可用设备为0时,应给用户相应的...
现有技术中,基于SANE协议框架下搜索可用的扫描设备通常都是先通过sane_get_devices()遍历轮询当前计算机中安装的所有扫描驱动,然后基于获取到的扫描驱动再确认是否有... 注意:该技术已申请专利,请尊重研发人员的辛勤研发付出,在未取得专利权人授权前,仅供技术研究参考不得用于商业用途。
深入浅出Pyinsane:Python实现的Sane API解析 ### 摘要 Pyinsane是一个利用ctypes和抽象层技术实现的纯Python版本Sane API,它不仅兼容Python 2.7和3.x版本,还通过Pillow和libsane库的支持,极大地简化了扫描仪的使用流程。用户可以通过简洁的代码示例轻松实现扫描功能,降低了技术门槛。 ### 关键词 Pyinsane, Sane API,...
其设计思路是:在选择更新设备后,调用sane_get_devices来获得可用的设备列表。实现时,为了允许用户在更新设备时进行其他操作,可将更新的操作放至一个新的线程中去实现。当可用设备为0时,应给用户相应的提示。 2.2 列出选项 根据测试需要,这里要求给出SANE后端的版本号,可用选项的详细信息以及警告信息。关于版本号,...

After so many months in the relative quiet of your office at home, you might get distracted by the hustle and bustle of working around other people. So embrace technology and invest in a pair of noise-cancelling headphones like theGalaxy Buds2. Even if you don’t like to listen to m...
sane.py: Make arr_snap return a 3D numpy array, shaped (samples, width, height) Remove multipleOf support in arr_snap, this should be done by the caller Overall cleanup Expose the localOnly option to sane.get_devices() Documentation: New python-sphinx generated documentation, reworked example...
* sane_get_devices() now takes a second argument of boolean type. If it's SANE_TRUE, then the backend must return local (non-remote) devices only. * scan now uses the default-unit of `mm' (millimeters) again for lengths.Using `cm' (centimeter) proved confusing since the help ...
