i2OCR is a free online Optical Character Recognition ( OCR ) that extracts text from images so that it can be edited, formatted, indexed, searched, or translated. <ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto"> <toolkit:Viewbox x:Name="viewbox" Height="250" Width="350"> <Grid Background="White" Height="250" Width="350"> ... </Grid> </toolkit:Viewbox> </ScrollViewer> </UserControl> Notice that initially the Viewbox is given exactly the same hard-coded size as the Grid inside. This ensures that the Viewbox doesn t need to perform any initial scaling instead, the Grid is at its natural size when the application first starts. When the user turns the mouse wheel, a MouseWheel event handler checks the delta and simply adjusts the Width and Height properties of the Viewbox proportionately. This expands or shrinks the Viewbox, and rescales everything inside: Private Sub Page_MouseWheel(ByVal sender As Object, _ ByVal e As MouseWheelEventArgs) ' The Delta is in units of 120, so dividing by 120 gives ' a scale factor of 1.09 (120/110). In other words, one ' mouse wheel notch expands or shrinks the Viewbox by about 9%. Dim scalingFactor As Double = CDbl(e.Delta) / 110 ' Check which way the wheel was turned. If scalingFactor > 0 Then ' Expand the viewbox. viewbox.Width *= scalingFactor viewbox.Height *= scalingFactor Else ' Shrink the viewbox. viewbox.Width /= -scalingFactor viewbox.Height /= -scalingFactor End If End Sub javascript ocr demo: JavaScript OCR demo tesseract ocr example javascript Javascript Credit Card OCR Prototype - Topcoder

Tesseract.js is a pure Javascript port of the popular Tesseract OCR engine. This library supports more than 100 languages, automatic text orientation and script ... The initialization vector (IV), or salt, is an important aspect of encryption security. The IV is a block of bits that further obfuscates the result of an encryption. The idea is that the IV will help prevent the same data from generating the same cipher text if it is encrypted more than once by the same key and algorithm. SQL Server does not allow you to specify an IV when encrypting data with a symmetric key, however. Instead SQL Server generates a random IV automatically when you encrypt data with block ciphers like AES and DES. The obfuscation provided by the IV helps eliminate patterns from your encrypted data patterns that cryptanalysts can use to their advantage when attempting to hack your encrypted data. The downside to SQL Server s randomly generated IVs is that they make indexing an encrypted column a true exercise in futility. In addition to random IV generation, SQL Server s EncryptByKey and DecryptByKey functions provide another tool to help eliminate patterns in encrypted data. Both functions provide two options parameters: an add authenticator flag and an authenticator value. If the add authenticator flag is set to 1, SQL Server will derive an authenticator from the authenticator value passed in. The authenticator is then used to obfuscate your encrypted data further, preventing patterns that can reveal information to hackers through correlation analysis attacks. If you supply an authenticator value during encryption, the same authenticator value must be supplied during decryption. ocr html5 canvas JavaScript text recognition and OCR on < canvas > - Stack Overflow

As you would hope, you are able to build a common UI of a *.master file using the same Visual Studio 2005 designers used to build *.aspx files. For your site, you will add a descriptive Label (to serve as a common welcome message), an AdRotator control (which will randomly display one of two images), and a Menu control (to allow the user to navigate to other areas of the site). Figure 26-6 shows one possible UI of the master page that we will be constructing (again notice that the content placeholder is empty). Also notice that the AdRotator widget is simply displaying a red X right now, as we have not specified an image for it to display. Ordinarily, every time an element receives a mouse button down event, it will receive a corresponding mouse button up event shortly thereafter. However, this isn t always the case. For example, if you click an element, hold down the mouse, and then move the mouse pointer off the element, the element won t receive the mouse up event. In some situations, you may want to have a notification of mouse up events, even if they occur after the mouse has moved off your element. To do so, you need to capture the mouse by calling the MouseCapture() method of the appropriate element (MouseCapture() is defined by the base UIElement class, so it s supported by all Silverlight elements). From that point on, your element will receive the MouseLeftButtonDown and MouseLeftButtonUp event until it loses the mouse capture. There are two js ocr demo JavaScript OCR demo
