问题 I'm trying to make an Excel workbook to track a stock balance. Right now my workbook is set up with an Inventory, Deposit and Withdrawal sheets. Inventory sheet contains codes and quantity for each item in stock. I want to enter the item code in A1 cell on either the Deposit or Withdrawal sheet, then a program should take the number and see if it matches anything in the Inventory sheet, if it does then it should either add 1 to quantity of that item, or remove, depends on the Deposit or

How can I inject a dynamically generated image (barcode, as it happens) into a PDF document (I'm in rails if that matters)?

由 |▌冷眼眸甩不掉的悲伤 提交于 2021-02-08 04:57:05
问题 I'm aware of pdf-stamper, but I'm trying to avoid switching everything to jruby right now. I just need to "stamp" an image that I generate within the rails app (a PDF417 barcode) into a form field in the PDF document (there's an FDF; it's a document template kinda thing). I'm filling out the text-based fields by just shelling out to pdftk, so if there's a way to do it using pdftk, I'd be fine with that, but I've looked high and low for one without any luck. 回答1: How about using a barcode font

Is this code for calculating Code128 barcode check digits correct?

由 依然范特西╮ 提交于 2021-02-07 08:29:09
问题 Based on my understanding* of the check digit calculation for Code128 barcodes (which differs radically/drastically from most of the other standard barcode types), my code below is correct. However, I would appreciate a "sanity check" by those who may know better/have some empirical observations/mud from the trenches attached to their trench (or lab) coats. This is my understanding: Each character in the barcode, from the left, is first converted into its ASCII code (IOW, a barcode character

How to catch input on document[keypress] on window in javascript from Zebra mc330m scanner?

由 ↘锁芯ラ 提交于 2021-01-29 08:18:17
问题 I configured the scanner to send Enter at the end of the input and js reads it correctly but the other characters are lost. I have tried to decode the input characters with event.keyCode, event.which, event.charCode and nothing works. If I attach it to normal input it works. It also works in the browser address bar (chrome). But when I attach it to the document['onkeypress'] it doesn't read the characters. I tried Martin Orth solution from here: https://developer.zebra.com/thread/35513 but I

Read blurry barcode in python with pyzbar

由 我只是一个虾纸丫 提交于 2021-01-05 05:51:42
问题 I have been trying to read some barcodes from images uzing Python and pyzbar. Unfortunately, the images are taken from several feet away under several constraints and I cannot move or zoom the camera any closer. Is it possible to read barcodes this blurry using any existing Python libraries? So far I've tried some preprocessing including thresholding, sharpening, applying a vertical closing filter, and Wiener filtering, but none seem to help. I am probably asking for a miracle, but if you

Amazon亚马逊常见的几种label

由 两盒软妹~` 提交于 2020-12-25 10:42:37
供应链中时常听到这样一个名词——label，中文意思是标签。标签种类多样，贯穿供应链的始终，每个行业，甚至每个企业所使用的标签都不尽相同。但无论是哪一种标签，其核心目的都是标记产品信息，从而提高企业的库存跟踪和管理的效率。 本文介绍Amazon亚马逊常见的标签类型，主要包括从亚马逊网络平台上直接下载的标签以及通过EDI的方式传输业务数据时使用的标签。与亚马逊合作的供应商一定知道，使用亚马逊平台可以直接生成标签，但如果供应商使用EDI系统对接亚马逊，亚马逊将提供一个新的标签，供应商可以在此示例模板的基础上设计自己的标签。亚马逊常见的标签类型包括： 物料标签：亚马逊每个可运输/可销售的单元在其产品外部都必须有一个产品识别号，常见的产品识别号有UPC、ISBN、EAN，GTIN-12和ASIN等。这些产品识别号通常以条形码加数字的形式印在其销售包装的醒目位置。 箱贴：亚马逊要求其供应商在纸箱外贴上标签，用以表示箱内物品的信息。每个箱子必须有箱贴，且需要保证一张标签上同时具备文字和条形码信息。最常用的箱贴标准是SSCC标准(序列装运集装箱代码)，亚马逊SSCC标准箱贴的示例如下图所示，主要包含产品名称、每箱物料数量、发货地、UPC编码（通用产品信息）、P/N（零件号）、订单编号、ASIN(亚马逊标准标识号)等信息。 注：ASIN是亚马逊商品的特殊编码标识，是随机生成的字母数字组合
