问题 Please help me out by sharing the step by step procedure to achieve the scanning functionality using Twain in ASP.Net MVC5. Thank you 回答1: At this moment, none of the browsers support scanning out of the box. You need to use a third-party library (not part of Microsoft's .NET core components). Below example uses Scanner.js, which is a product offered by our company: Enable Scanning from TWAIN Scanners to ASP.NET Pages: Step by Step Below steps use Scanner.js as example; they may differ for

Scanned Image to Readable Text

由 我们两清 提交于 2019-12-24 05:59:13
问题 I am wondering is there a way to get scanned image with text to be converted to readable text by writing code for it? Is that possible? 回答1: OCRTools is what I use for .net For Java, i've used Aspire in the past, it's very good, a little scary though. I've heard a lot about tesseract, you might as well check that out. If you are getting confused by the answer: What you are looking for is an Optical Character Recognition software's API/SDK. What you've asked in the question points to building

WIA's ShowAcquireImage only saves in BMP?

由 感情迁移 提交于 2019-12-24 00:37:08
问题 I am using the WIA 2.0 library within Delphi XE to automate scanning. I am using the " ShowAcquireImage " function to provide an image to be saved to disc. I want to save the image in a compressed format such as png or jpg, but the library only seems to save in bitmap. Has anyone else seen this problem, and is there a workround? (Apart from saving to disc as a big bmp file, and re-loading into a TJpegImage/TPngImage object, that is). Thanks for any advice PhilW. This the code I am currently

Fix the orientation of a PDF in order to scale it

问题 I am having some issues with a PDF containing a rotation property created by a Xerox scanner. The below function was originally created to scale the height of an input PDF by the amount given by the variable scaleHeight. This works fine for input documents without rotation. When testing a document with a 270 degree rotation, I found that the rotation property which would have made the document appear in a portrait orientation was ignored. Instead, the document appeared in a landscape

rose-scanning reading

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> rose-scanning的功能 把classpath中使用rose的jar包和folder都生成资源对象，供spring读取里面的bean到beanfactory中（更准确是的RoseAppContext或RoseWebAppContext）。 自动打开annotation识别，不用再在xml中配置。 处理过程 new RoseAppContext或RoseWebAppContext，后面用RoseAppContext代替。 RoseAppContext构造函数中最后会调用在父类AbstractApplicationContext中实现的的#refresh()方法。 在#refresh()方法中会调用一些列方法，最后调用到AbstractXmlApplicationContext#loadBeanDefinitions(XmlBeanDefinitionReader reader),这个里面会调用RoseAppContext中重写的#getConfigResources()方法。这个方法是为了获取xml配置文件的位置，然后让后面的reader去读取到Context中。 在#getConfigResources()方法中调用RoseResources#findContextResources()

问题 WIA Scanning via Feeder Here is my device properties: Document Handling Select = 1 (2 is for flatbed, and 1 is for the feeder.) Here is my item (page) properties: Horizontal Resolution = 150 Vertical Resolution = 150 Horizontal Extent = 500 (I want to get it first to work, then I'll play with the extents.), Vertical Extent = 500 Bits Per Pixel = 8 Current Intent = 4 I got everything running smoothly if I set the "Document Handling Select" to "2". When I set it to "1", and ran it, just before

C# WIA with Automatic Document Feeder (ADF) retuns only one page on certain scanners

问题 I have a HP Scanjet 7000 (duplex & ADF scanner) and a HP Scanjet 5500c (only ADF) and a scanner program I'm developing which uses WIA 2.0 on Windows 7. The problem is that the code works perfectly on the older scanner model, but on the newer one the code seems to run just fine through the first page, then fail on the second. If I step through the code around the following line; image = (WIA.ImageFile)wiaCommonDialog.ShowTransfer(item, wiaFormatTIFF, false); the old scanner stops and waits for
