The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The license only requires software under the LGPL be modifiable by end users via source code availability. The license allows developers and companies to use and integrate software released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. The GNU Lesser General Public License (LGPL) is a free software license published by the Free Software Foundation (FSF). Wikipedia’s discussion is actually right on for a change: For example, the C library is LGPL or you wouldn’t be able to create ANY commercial, closed source app for Linux at all. LGPL has the caveat that you can use it in a commercial application without the need to open source the commercial app so long as you include/make available the source code for the library as part of your app. Will be included in next prerelease or if you like to try now, please do not hesitate to contact Winter: The example project lists all the devices and even works nice on Raspberry Pi. You can open a connection to a device and transfer data as needed. The new LibUSBDeviceMBS class provides functions to list devices and query information. The library itself is licensed LGPL, so you can load it in commercial applications, but distribute it as DLL/so/dylib file. With quite a few Linux distributions, it comes preinstalled. The new plugin classes are based on the open source LibUSB library, which works on MacOS, Windows and Linux. Wether this is a scale to weight items, barcode devices, various sensors or just a special label printer, we do provide classes to help you.įor some time now we got HIDAPI classes to replace the older MacHID, LinuxHID and WinHID classes to provide a cross platform interface for USB devices with HID protocol.Īnd now we replace MacUSBConnect and WinUSB classes with our new LibUSB classes. The "-" is interpreted as "page 1 to the end of the document".Quite a few Xojo developers use our MBS Xojo USB Plugin to connect to devices, do measurements, exchange data and query information for their applications. The "2-" is interpreted as "pages 2 to the end of the document". The following examples assume a document with 20 total pages. If page range is not valid or if a page is greater than document total page count, ArgumentException is thrown. The pages are always printed in ascending order, even if specified in non-ascending order. To print multiple times, use the Copies property. Repeating a page does not print it multiple times. If the last page is not present, then the document total page count is used as the last page. The last page must be larger than the start page. If the start page is not present, then 1 is used as the start page. In a page range of the form - the start page number must be larger than 0 and less than or equal to the document's total page count. Every page identifier is an integer greater than 0 unless wildcards are used (see below examples). A valid page range is either a single integer identifying the page to print, or a range in the form - where start page and last page are integers identifying the first and last inclusive pages respectively to print. Any whitespace between page ranges is ignored. The PageRanges property is a list of page ranges specifying one or more pages that should be printed separated by commas. PageRanges as Stringĭefaults to empty string, which means print all pages.
