![]() ![]() Supported formats include: Enter an image URL: Or upload a file (<10MB, <10MP): This web application is powered by the barcode scanning implementation in the open source ZXing project. This will delete the image from our storage. ZXing Decoder Online Decode a 1D or 2D barcode from an image on the web. Paste the generated URL in the following form and submit. At any time, the image can be deleted using the same URL. When a QR code is generated the image is saved in a storage service to be publicly accessed through a URL. How can I delete the image that I have uploaded? Only you can delete the images that you have uploaded as a user, while if you are not authenticated, anyone can delete them. You can enable or disable the assigned image, upload new images or permanently delete the QR code. With your LightenPic user account you can save and manage your QR codes. We guarantee the saving of the image for 90 days. LightenPic will upload your image to the cloud and generate a QR code through which to access a page where it is viewed, all in a single step. You can scan the code at any time to access the picture saved in the cloud. Test your QR code and make sure it leads to the correct data. LightenPic QR Code Generator is a easy and free way to turn image into qr code. After you are finished entering the information you need, click the generate QR code button.You can also choose to customize your QR code and add a logo, image, icon, set the colors and patterns of your choice to make it even more captivating. To download the full example and see more information on the classes and methods used in this code tip, check out the original forum post.Select your image You can convert a picture to a QR Code and can use any valid format, such as jpg or png. Writer.WriteBarcode(image, data, writeOptions) Writer.CalculateBarcodeDataBounds(new LeadRect(0, 0, image.ImageWidth, image.ImageHeight), image.XResolution, image.YResolution, data, writeOptions) WriteOptions.VerticalAlignment = BarcodeAlignment.Near WriteOptions.HorizontalAlignment = BarcodeAlignment.Near QRBarcodeWriteOptions writeOptions = writer.GetDefaultOptions(data.Symbology) as QRBarcodeWriteOptions QRBarcodeData data = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData ĭata.Bounds = new LeadRect(0, 0, image.ImageWidth, image.ImageHeight) Using (RasterImage image = RasterImage.Create((int)(8.5 * resolution), (int)(11.0 * resolution), 1, resolution, RasterColor.FromKnownColor(RasterKnownColor.White))) String recognizedCharacters = ocrPage.GetText(-1) īarcodeEngine engine = new BarcodeEngine() OcrEngine.Startup(null, null, null, (IOcrPage ocrPage = ocrEngine.CreatePage((imagePath, 1), OcrImageSharingMode.AutoDispose)) Using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false)) Create and use OCR to get text from the image ![]() It doesn’t take much to do either of these advanced imaging processes with LEADTOOLS.Ĭheck out the following code snippet that loads an image, OCRs the text, then creates a QR Code on a blank image. OCR Web Service allows you to: Convert image to text or extract text and characters from scanned PDFs or images. Or even better yet, use your mobile phone to capture a picture of the text you want to convert into a QR code. Or use zonal OCR to convert just a block of text into a QR code. Plus, they can pack in a ton of information so you can encode and squeeze all the text from a document into a QR code. That may be true, but you’re only thinking about reading.Ĭreating barcodes, especially QR codes, is still an important and popular task. Most of the time you probably think of OCR and Barcodes as the last step in a document imaging process: How about something a little less common, like OCR + Barcode? Huh? Those don’t really go together do they? ![]() There are many applications, especially in the document imaging world, where technologies intersect and you may find the need to piecemeal multiple SDKs together.įor example, Scanning + Document Cleanup + OCR, OMR + Forms Recognition + OCR, or OCR + PDF. We developed LEADTOOLS with the mindset that we want it to be a one-stop-shop for imaging. We take great pride in the fact that LEADTOOLS is truly a comprehensive imaging SDK. ![]()
