Generate QR Code in PHP with PHP QR Code Generator source code

A QR code (abbreviated from Quick Response code) is a type of matrix bar-code (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the automotive industry due to its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols).

This specifies how much of the data's codewords (8-bits per codeword) can be restored for a distorted or damaged QR Code image using the Reed-Solomon error correction algorithm. The higher the correction level, the less the data capacity of the barcode can be for a given dimension. Below is a table mapping the levels to their restore percentages and the string constants used when calling the PHP QR Code library.

How to convert Video to mp3 (Convert MP4 to MP3) on windows?

MP4 files are used to store and watch videos, while MP3 files are used to store and listen audio. The MP4 and MP3 file formats have the same lineage, they all come from the File Compression Experts Group (MPEG) format. In addition, in terms of attributes, the MP4 file format and the MP3 file format are very similar. The only major difference between the two is that the MP4 format is used for video and the MP3 format is used for audio.

In this case, simply strip the video content to convert MP4 files to MP3 files.

Is the "convert white background color to transparent background color" possible with the GUI version of VeryPDF PDF Stamp software?

Can the stamp be protected or made so that it is not possible to copy and paste it into another application or document? I want to use it to add a signature image to drawings and do not want people to be able to copy that signature.
