barcode

问题 Does anyone know a good sdk for reading and decoding 2d barcodes (preferably Datamatrix or QR) from within a Java ME application? The application will be closed source, and while I'd prefer that the SDK be free (perhaps MIT or LGPL licenses), I would not mind forking over some cash for a commercial license. I've come across the Semacode SDK but it's GPL licensed and the links to the commercially licensed version do not seem to be working. There's also one from http://qrcode.sourceforge.jp but

问题 How to find out which type of barcode is this in my sample ? I looked on wikipedia and there are quite many types of barcodes, most common should be Code 39 and Code 128. Is there any lib for barcode OCR (python, java, C#, delphi) ? On this barcode should be encoded time and date of expiration. EDIT I need to know how to read and decode above barcode. This barcodes were generated in legacy system and It would be nice if my app could OCR and understand them On my barcode should be date 19.11

问题 Currently I'm programming a label-writer (Brother QL-570, if it matters, in Java) to print barcodes with different ID's. The length of the barcode data can vary from ~17 characters to ~3. However, given that I've understood the barcode-concept correctly, the more data - the wider will the barcode become. I'd prefer if all barcodes had the same, contstant size: no matter data-length. (It won't look good if the barcode doesn't fill up the label, nor will it (work) if it's too large) How can one

问题 I recently purchased a 2D Barcode reader. When scanning a U.P.S. barcode, I get about half of the information I want, and about half of it looks to be encrypted in some way. I have heard there is a UPS DLL. Example - Everything in bold seems to be encrypted, while the non-bold text contains valuable, legitimate data.

问题 Im a little bit confused because I can display every string with every font on my windows form but as an image it is not always possible. Maybe there is just something wrong with my code. But let me show you what I was trying. At first I have this: Label l = new Label(); l.Text = "Ì CSharp Î"; this.Font = new Font("Code 128", 80); l.Size = new System.Drawing.Size(300, 200); this.Controls.Add(l); this.Size = new Size(300, 200); Well this is very fine. Now I would like to try to save the same

问题 I want to integrate the zing barcode scanner to my android application. so i used zing integrator as follows public Button.OnClickListener mScan = new Button.OnClickListener() { public void onClick(View v) { Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.setPackage("com.google.zxing.client.android"); intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); startActivityForResult(intent, 0); }};public void onActivityResult(int requestCode, int resultCode, Intent intent) { if

问题 I've been using libdmtx in a project and looking to update to a newer version, but it seems the project hasn't been updated in well over a year. The last update/version was June, 2011. The Git repository shows that the last commit was August, 2011. Finally, the author's web site, which previously promoted libdmtx, Dragonfly Logic, is dead with a 404 Not Found error. Is there another data matrix library that can meet this criteria? Open source Platform-neutral C/C++ (i.e. can build for Windows

问题 I am look at building a 13 digit EAN bar code scanner which works on the web on mobile devices and will use the devices camera to take an image of bar code to scan and decode. I'm not trying to do this through a native app as I would prefer to make this part of my native website search experience. E.g. website visitors on a mobile will be prompted to scan a bar code without having to open an app. This script works well on desktop https://github.com/EddieLa/JOB and uses the Navigator
