Bertemu kembali untuk melanjutkan tutorial tentang aplikasi sambapos yang sebelumnya telah kita pelajari bersama. Pada kesempatan kali ini saya akan membahas tentang cara setting untuk VFD Customer display, yaitu untuk menampilkan banner pada VFD yang terintegrasi pada POS PC.
Disini saya akan membuat beberapa banner yang akan ditampilkan pada VFD display yaitu banner selamat datang, banner closed / kasir tutup, banner display item dan total harga. Untuk mempersingkat waktu mari kita langsung aja ke tee.kaa.pee chekidotttttt Pertama-tama yang harus dipersiapkan yaitu unit POS PC yang sudah memakai VFD customer display. Disini saya menggunakan type WD-2025 VFD Display dengan 20 columns dan 2 line. Mungkin ada yang bertanya apa itu VFD display? Dengan gambar di bawah ini mungkin bisa sedikit menjawab pertanyaan tersebut. Setelah siap dengan unit POS PC dan VFD nya, mari kita mulai untuk mengimplementasikannya dengan aplikasi SAMBAPOS yang telah kita install sebelumnya. Selanjutnya kita buka aplikasi SAMBAPOS, kemudian LogIn dengan User administrator supaya bisa masuk ke dalam menu Setting.
Setelah itu kemudian masuk menu Manage kemudian pilih Printer, setelah itu kemudian klik Add New Printer. Setelah muncul tampilan Adding New Printer kemudian masukan parameternya sebagi berikut:.
Printer Name VFD Display. Printer Share Name / Port Name COM6. Printer Type Port Printer. Character set 857. Line Count 2.
Line Character Count 20 Dimana disetiap option pengisian parameternya tidak perlu dijelaskan kembali karena sudah dijelaskan pada tutorial sebelumnya, untuk lebih jelasnya bisa dilihat pada gambr dibawah ini: Setelah semuanya selesai dimasukan kemudian klik “Save” untuk menyimpan settingannya. Kemudian sekarang kita loncat dulu ke Printer Template sebelum mengerjakan Print Job. Disini kita akan membuat 4 buah Template banner yaitu “Display Item”, “Display Banner”, Display Total” dan “Display Closed”.
Caranya klik Printer Template Kemudian klik Add New Printer Template, Setelah muncul jendela Adding New Printer Template masukan rancangan templatenya sebagai berikut a. Display Item b.
Display Banner c. Display Total d. Display Closed Lanjut kembali setelah selesai membuat Printer Template, sekarang kembali lagi untuk membuat settingan Print Job-nya. Disini kita akan membuat 4 settingan untuk Print Job-nya yaitu untuk “Display Item”, “Display Banner”, “Display Total” dan “Display Closed”. Caranya yaitu pilih Print Job kemudian klik Add Print Job setelah muncul jendela Adding New Print Job Masukan parameternya seperti pada gambar dibawah ini: a. Display Item b. Display Banner c.
Display Total d. Display Closed Lanjut kembali setelah selesai membuat Print Job, sekarang kembali lagi untuk membuat settingan Action-nya. Disini kita akan membuat 4 settingan untuk Action-nya yaitu untuk “Display Item”, “Display Banner”, “Display Total” dan “Display Closed”. Caranya yaitu pilih Action kemudian klik Add New Action setelah muncul jendela Adding New Action, Masukan parameternya seperti pada gambar dibawah ini: a. Display Item b. Display Banner c.
Display Total d. Display Closed Lanjut kembali setelah selesai membuat Action, sekarang kembali lagi untuk membuat settingan Rules-nya. Disini kita akan membuat 4 settingan untuk Rules-nya yaitu untuk “Display Item”, “Display Banner”, “Logged In Banner” dan “Logged Out Closed”.
Caranya yaitu pilih Rules kemudian klik Add New Rules setelah muncul jendela Adding New Rules, Masukan parameternya seperti pada gambar dibawah ini: a. Display Item b. Display Banner c. Logged In Banner d.
Logged Out Banner Baiklah setelah selesai semua, sekarang kita masukan settingannya ke dalam terminal untuk di eksekusi. Caranya yaitu masuk ke menu terminal kemudian pilih terminal server kemudian edit. Pada jendela edit terminal server cari select Print Job, kemudian pindahkan Print Job yang telah kita buat tadi yaitu “Display Item”, “Display Banner”, Display Total” dan “Display Closed” dari sebelah kiri ke sebelah kanan, setelah semuanya selesai kemudian klik OK dan diakhiri dengan klik “Save” untuk menyimpan settingannya. Untuk lebih jelasnya bisa dilihat pada gambar dibawah ini: Setelah selesai semuanya, lakukan LogOut dari program dan keluar terlebih dahulu dari program SAMBAPOS. Sekarang kita akan coba hasilnya, buka aplikasi SAMBAPOS kemudian LogIn dengan User masing-masing, setelah LogIn dan masuk ke program coba lihat pada VFD Customer Display. Lakukan transaksi dan lihat juga apakah ada perubahan? Mudah-mudahan berhasil.

Sampai disini dulu untuk tutorial Setting VFD Customer Displaynya semoga berhasil dan menambah sedikit pengetahuannya, mohon maaf jika ada salah-salah karena saya juga sama-sama sedang belajar, mohon bantuannya atau masukannya dari para master-master di bidang ini supaya menambah pengetahuannya lebih luas lagi. Mudah-mudahan dengan pencerahan yang sedikit ini bisa bermanfaat khususnya bagi saya dan umumnya bagi semuanya yang sudi untuk membacanya. Sekian dan terimakasih atas perhatiannya, sampai jumpa lagi pada kesempatan yang lainnya pada tutorial yang lainnya. Let’s imagine that you need to digitize a page of a book or a printed document, you will use a scanner to create an image of the real page. However although you have the rights to edit the content of the scanned book, you can’t edit it in your computer because it’s an image, and you can’t simply edit an image as if it were a digital document. Yeah, the user can use programs that creates PDF with selectable text and then they can do what they want, however as a developer, you can offer your user the possibility of extract the text from images using the Optical Character Recognition technology.
To achieve our goal of converting images to text, we are going to use Tesseract written in C installing it in the system and then using the command line with the PHP wrapper. In this article you will learn how to extract the text from an image in a Symfony project with the help of Tesseract. Install Tesseract in your system In order to use the optical character recognition API, as mentioned in the article, we are going to use Tesseract.
Is an open source Optical Character Recognition (OCR) Engine, available under the Apache 2.0 license. It can be used directly using an API to extract typed, handwritten or printed text from images. It supports a wide variety of languages (that needs to be installed). Tesseract supports various output formats: plain-text, hocr(html) and pdf. The installation process of Tesseract in your system will vary according to the Operative System that you use: Windows The installation of Tesseract in Windows is pretty simple, we recommend you. You can get (download always the most recent version).
The installation process is very straightforward, just follow the wizard. However we recommend you to install directly all the languages that you need for tesseract in the setup (only the ones you need, otherwise the download process will take long) and register tesseract in the PATH a Windows environmental variable: C: Program Files (x86) Tesseract-OCR tesseract.exe All the trained language data should be saved in TESSDATAPREFIX, a Windows environmental variable, which is at C: Program Files (x86) Tesseract-OCR tessdata in your case. In case you need more information or your operative system isn’t listed, please refer to the.
Install the Tesseract PHP wrapper To handle Tesseract with PHP, we are going to use the most known Wrapper of Tesseract written. Is an useful and very easy to use wrapper of the command line instructions for Tesseract OCR inside PHP. The preferred way of installation is via composer, you can execute the following command directly in the terminal: composer require thiagoalessio/tesseractocr 1. Note: you need to install the specified version as in the documentation of the library, the method to recognize the text in the image using Tesseract is $tesseract-run. In the older versions you need to use $tesseract-recognize instead. Implementation within a controller The usage of the library is pretty simple and easy to understand: run ( ); // Show recognized text echo $result.
Navigate to the route that matches the index action of this controller, and you will see as output the recognized text of the image. Support languages As you known, there are other languages in the world that uses special characters, that’s why Tesseract offer different languages packs. For example, if you try to recognize the following image without the german package: You’ll get as result “griifien”. That isn’t true at all, that happens because these characters are of the german language. To solve it, you need to add the german package (identified with deu): lang ( 'deu' ); // Execute tesseract to recognize text $result = $tesseractInstance - run ( ); echo $result. Note: in order to use different languages, you will need the respective packages installed too.
Custom options If you already read some content of, you know that there are a lot of properties that you can change. The PHP wrapper of tesseract provide some methods for the most used options: Change executable path For different reasons, you may not have tesseract available directly in the environment variable PATH, therefore the execution of a command with the php wrapper “ tesseract imagename.jpeg outputbase” won’t work.
You can specify the location of the tesseract executable with the executable method: $tsaInstance = new TesseractOCR ( 'image.jpeg' ); // For example in Windows, you need to wrapp the path in double quotes to make it work. $executablePath = 'C:/Program Files (x86)/Tesseract-OCR/tesseract.exe'; $tsaInstance - executable ( $executablePath ); $recognized = $tsaInstance - run ( ). Value Description 0 Orientation and script detection (OSD) only. 1 Automatic page segmentation with OSD. 2 Automatic page segmentation, but no OSD, or OCR.
3 Fully automatic page segmentation, but no OSD. (This value is used by default if none providen) 4 Assume a single column of text of variable sizes.
5 Assume a single uniform block of vertically aligned text. 6 Assume a single uniform block of text. 7 Treat the image as a single text line. 8 Treat the image as a single word.
9 Treat the image as a single word in a circle. 10 Treat the image as a single character.
Set languages to recognize You can define one or more languages to be used during the recognition using the -lang($lang1, $lang2) method. You can get a list of: $tsaInstance = new TesseractOCR ( 'image.jpeg' ); // To provide full chinese recognition $tsaInstance - lang ( 'chisim', 'chitra' ); $recognized = $tsaInstance - run ( ). This list is really useful when dealing with contents that contain technical terminology. Whitelist characters You can even limit the characters that tesseract will recognize, for example with the following image: Tesseract will recognize 'BOSS'.
That’s great, cause in the image seems that someone wrote BOSS however, the user (probably a child or someone with bad calligraphy) wrote the number “8055”? That’s where the whitelist comes in handy, in this case we can limitate the characters to recognize only numbers using a range from 0 to 9: $tsaInstance = new TesseractOCR ( 'image.jpeg' ); // Recognize all in numbers $tsaInstance - whitelist ( range ( 0, 9 ) ); $recognized = $tsaInstance - run ( ). Giving as result the expected number “8055”. Set config value Tesseract offers more than 600 customizable properties (you can list them using in the console tesseract -print-parameters) that you can modify using the -config($propertyName, $value): $tsaInstance = new TesseractOCR ( 'image.jpeg' ); // Size of window for spline segmentation $tsaInstance - config ( 'textordsplinemedianwin', 6 ); // For smooth factor $tsaInstance - config ( 'textordskewsmoothoffset', 3 ); $recognized = $tsaInstance - run ( ). The images captured by the recent cameras often exceed 2 MB. Using such images frequently results in OutOfMemoryError. Also, due to landscape/portrait orientation, the images often are displayed as rotated. To deal with these issues we need to compress the image and give proper rotation before loading it to memory.
The following method compresses image (similar to whatsapp), while maintaining its aspect ratio and also preventing significant loss to its quality. A demo project implementing this compression can be downloaded from. By default php engine in WAMP Server provides import size of 2Mb. What if someone needs to import a large database, say 20Mb.
The Solution to increase the database size is given and which changes the original configuration permanently. Open php.ini files in C: wamp bin php php5.3.5 and C: wamp bin apache Apache2.2.17 bin and perform following in both files. Locate uploadmaxfilesize and set its value as large as you want. For example uploadmaxfilesize = 100M (M denotes Mb). Locate postmaxsize and set its value as large as uploadmaxfilesize. For example postmaxsize = 120M. Locate memorylimit and set its value as large as postmaxsize.
For example memorylimit = 140M What if we didn’t change postmaxsize? By default postmaxsize is set to 8M. So, phpMyAdmin will not extend it’s import size greater than 8M.
