kandi X-RAY | QRCode Summary

QRCode is a C++ library typically used in Utilities, QRCode Processing applications. QRCode has no bugs, it has no vulnerabilities and it has low support. However QRCode has a Non-SPDX License. You can download it from GitHub.

A QR code is composed of many little squares, called modules, which represent encoded data, with additional error correction (allowing partially damaged QR codes to still be read). The version of a QR code is a number between 1 and 40 (inclusive), which indicates the size of the QR code. The width and height of a QR code are always equal (it is square) and are equal to 4 * version + 17. The level of error correction is a number between 0 and 3 (inclusive), or can be one of the symbolic names ECC_LOW, ECC_MEDIUM, ECC_QUARTILE and ECC_HIGH. Higher levels of error correction sacrifice data capacity, but allow a larger portion of the QR code to be damaged or unreadable. The mode of a QR code is determined by the data being encoded. Each mode is encoded internally using a compact representation, so lower modes can contain more data.

As far as I understand, you are just looping through the candidates array but you are not storing the updated array. You need to store the updated data in a variable as well. Please give it a try with the solution below using map.

QUESTION

How to add android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED when creating enrollment token for afw#setup enrollment

Asked 2022-Mar-18 at 18:55

We successfully can add android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED:true to a qrCode bundle by injecting the property into the returned enrollment token before converting to a QR code which will indeed leave system apps enabled; however, I would like to have the option to enroll a device using the afw#setup DPC enrollment method by entering the returned token value in as a manual code instead of creating a QR code.

When creating the token via Method enterprises.enrollmentTokens.create, is there any way to pass the android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED:true property when creating the token to allow this property to take effect while manually entering the token value? Or is that property only allowed to affect QR code enrollments rather than manual ones?

For example, I want to use this DPC identifier method by entering the code manually but with the passed android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED:true

Here is the documentation: https://developers.google.com/android/management/provision-device#dpc_identifier_method

I have tried multiple ways to set a qrCode value during token creation but the property never shows up in the returned enrollment_token object. For example if I use this to create a token:

ANSWER

Answered 2022-Mar-18 at 18:55

The API generates the contents of the qrCode field. When manually inputting the enrollment token during afw#setup enrollment, you cannot use DPC extras like android.app.extra.PROVISIONING_LEAVE_ALL_SYSTEM_APPS_ENABLED.

Extras are only usable when provisioning devices via QR Code or Zero Touch.

How do I combine Text and an Image File into one Image File in Flutter?

Asked 2022-Mar-17 at 20:01

Below is a snippet of code from a function that uploads a generated QR code (using the qr_flutter package) to firebase storage; then gets the firebase storage url to save in a custom model that is uploaded to firebase firestore (not shown).

This works fine, however I want to upload a file that consists of the QR code bounded by title text above and address text below. (Essentially a Column with children [title, qrFile, address]).

My question is: How do I combine Text and my qrFile into a single image file that I can upload to firebase storage?

One solution is to use the screenshot package (https://pub.dev/packages/screenshot). This package has a function to save a widget as an image (without displaying it on screen) as shown below.

Return inline dynamic SVG from MVC Controller

Asked 2022-Mar-11 at 11:50

I'm building a method on my Controller to generate an SVG QR Code (QRCoder) and I'm trying to inline the resultant SVG from the controller into the View using a Method on the Controller.

When I attempt to view the method directly, I see the SVG XML coming back successfully, but it's getting an exception. I'm not quite sure what I need to make my controller return so that I can do this in my view.

The version of OpenCV you get with the apt package is always fairly old. Additionally, there's no guarantee that all the modules (here: the QR decoder) were given the required dependencies (here: quirc). Installing additional packages wouldn't solve this because OpenCV needs them at build time, before packaging.

To get the most recent version, install it via pip:

ANSWER

Answered 2022-Mar-05 at 12:06

self.pushButton_3.clicked.connect(self.generate()) at this line you are not connecting the generate function but you are calling it by adding () to function name, so change it to self.pushButton_3.clicked.connect(self.generate) and self.generate should accept one argument x which is callback event of pushbutton

so either change definition of self.generate which accepts one argument or make a lambda function which accepts one argument and calls self.generate by placing this line self.pushButton_3.clicked.connect(lambda x: self.generate())

You need to invert the colors and have a white border around the image, like this:

The border around the image should have at least the width of the QRCode's pixel, so if the smallest square inside the image has 8×8px, then the border should have at least 8px.

The color outside the border can be white too.
