If i set logo from DrawableSource.Resource it crash my app, if i set DrawableSource.Empty all ok
I convert drawable to bitmap and it throw me error if i set logo

I'm using this simple vector image, that displays a circle
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="40dp"
android:height="40dp"
android:viewportWidth="40"
android:viewportHeight="40">
<path
android:pathData="m0,20a20,20 0 0,1 40,0a20,20 0 0,1 -40,0z"
android:fillColor="#000000" />
</vector>
When the size of the qr code view is not an integer - for example, I want it to take up part of the screen width, say 0.6, the logo is drawn rather pixelated. If I round up the size, it's drawn as it should be. Here is a sample code in Compose:
val textContent = LoremIpsum().values.first().take(300)
val context = LocalContext.current
val drawable = remember(textContent) {
QrCodeDrawable(
data = QrData.Text(textContent),
options = QrVectorOptions.Builder()
.setErrorCorrectionLevel(QrErrorCorrectionLevel.High)
.setLogo(
QrVectorLogo(
drawable = AppCompatResources.getDrawable(context, R.drawable.ic_logo),
padding = QrVectorLogoPadding.Natural(.28f),
)
)
.setShapes(
QrVectorShapes(
darkPixel = QrVectorPixelShape.RoundCorners(0.5f),
ball = QrVectorBallShape.Circle(1f),
frame = QrVectorFrameShape.Circle()
)
)
.build(),
)
}
Image(
rememberDrawablePainter(drawable),
contentDescription = null,
contentScale = ContentScale.None,
modifier = Modifier
.size(300.5.dp)
)
Result with size 300.5.dp

When I generate a VCard QR code with a name in Cyrillic letters, when I scan the code, the name "Роман" became "?????", but if I set the name as "Roman", the code works correctly
Sorry for the noob question, new dev here!
I am using this version:
implementation ("com.github.alexzhirkevich:custom-qr-generator:2.0.0-alpha01")
jitpack is in my settings.gradle
maven("https://jitpack.io")
Yet theres a problem importing some functions:
import com.github.alexzhirkevich.customqrgenerator.QrData
import com.github.alexzhirkevich.customqrgenerator.createQrVectorOptions
import com.github.alexzhirkevich.customqrgenerator.dsl.QrVectorLogoShape
Unresolved reference: createQrVectorOptions
Unresolved reference: dsl
Am I missing something?
How to customise eyes like this, i tried and able to customise with same shape but all the sides are same! how to differentiate left top, right top and left bottom eye side?

Can you add the option to load a logo from the url and not just from resources? please
Thank you for your work, is very nice this library.
Is your feature request related to a problem? Please describe.
I created a QR code design which features randomly selected pixel highlights in my apps accent color.
It works fine most of the time as the error correction easily compensates those pixels.
But in some cases, when the higlight happens to be at an important area, like the center of an alignment pattern, it produces hard to read codes.
Describe the solution you'd like
The paint method of QrVectorColor and the shape method of QrVectorPixelShape should have an additional input parameter that gives some extra information about the current pixel.
This could either be a boolean that states if it belongs to a reserved area or an int that works like an enum stating exactly to which area it belongs.
The different reserved areas are:
Please refer to this page:
https://www.thonky.com/qr-code-tutorial/module-placement-matrix
Describe alternatives you've considered
The alternative would be to not use any highlights or to use a darker color. But I want to use my apps accent color and I like the way it looks now.
is there any way to use URI or Bitmap for the logo image?

Describe the bug
The quick documentation and viewing of source code does not work with intellij, this implies that it is not published
Versions
Library : '2.0.0-alpha01'
Android: 'N/A'
To Reproduce
Try quick documentation or view the source code in Android Studio
Expected behavior
Should be able to view the source code and documentation
Screenshots
If applicable, add screenshots to help explain your problem.
Additional context
You may try this plugin instead, as this auto configures gradle artifact publish
in 1.5.5 it was SweepGradient(List<Pair<Float, Int>>)) ==> java list is working
in 1.5.6 it is SweepGradient(Array<Pair<Float, Int>>)) ==> here is generic array so can not convert from java to kotlin

When set background image to the qr code for some images, scanner not able to scan the qr code.
i did research and found if background image has black part at any of 4 corners that eye can't be differentiated by the scanner and scanner can't read it.
Versions
Library : '8b2a97c5e6' and '1.6.1'
Android: '13'
Here is the QR Code which generated using this Library with background image (NOT SCANNABLE)
Here is the QR Code which generated online using same background image. (SCANNABLE)
When adding background image to the qr code they are adding some opacity around the eyes so scanner can differentiate eyes and background. also they highlight the fourth small eye (may be this can help to read qr code easily but i am not sure) check i marked with red arrow. Can you add this option or flag to add opacity around the eyes?
Hi Alex,
Thanks for this amazing example project, can you add support for Flutter for Custom Qr Generator?
I think will be amazing for pub.dev community!
Thanks in advance!
Without frame color and ball color symmetry shape is good
new QrVectorColors(getQRVectorColor(Color.BLACK),
QrVectorColor.Unspecified.INSTANCE, QrVectorColor.Unspecified.INSTANCE,
QrVectorColor.Unspecified.INSTANCE);
when frame color and ball color set getting this
new QrVectorColors(getQRVectorColor(Color.BLACK),
QrVectorColor.Unspecified.INSTANCE,getQRVectorColor(Color.BLACK),
getQRVectorColor(Color.BLACK));
Is there a way that we can make a gradient background that fills the whole qr
Right now lib has feature options.setPadding() which apply only to the QrCodeDrawable but when set background image it apply to whole area. Can we have that feature so we can give desire padding/margin to the background image too?
is it possible to add GIF image as foreground of QR Code?
Describe the option you are trying to implement
Hi, I try to create a QR code with random circle sizes and colors with the vector implementation.
Is this possible? The instagram example is only provided with the deprecated method.
It feels like this should be simple, but I can't find a way how to do this.
Thanks for your help.
P.S: If it is not possible yet I would love to see this feature implemented.
Is it possible to give different colours to eyes? right now colour applying to all eyes.

logo {
drawable = AppCompatResources.getDrawable(
context, R.drawable.ic_logo_telegram
)
size = .25f
padding = QrVectorLogoPadding.Natural(.2f)
shape = QrVectorLogoShape.Default
}
Result. If you set the playback speed to 0.5, the first telegram logo is opened, then the qr code.
Describe the bug
The code in example is invalid
Versions
Library : 'example'
Android: '11'
Change codeShape property from default to QrShape.circle(), will cause qr code can not be recognized.

I want my QR codes to be as small as possible.
I have to encode 64 character hex strings.
Describe the solution you'd like
The QR code specification defines 4 standard ways of encoding the data.
Numeric, Alphanumeric, binary & kanji.
I could encode hex strings way more efficiently if I just upper case them and then use Alphanumeric as encoding.
So in short:
It would be awesome if we could set the encoding option somehow.
Describe alternatives you've considered
The alterative are ugly big codes 😀

It seems to be more complicated to create a QR Code with square pixel shapes than it should be.
Describe the solution you'd like
There should be a built in QrVectorPixelShape.Square(size) shape modifier
Describe alternatives you've considered
Using QrVectorPixelShape.RoundCorners(0f) is different, as the shape cannot be scaled
I am generating QR code using zxing library...after generating, i am getting a bitmap image...can i edit QR code in the bitmap image in future instead of generating it again?
Taking too much time to generate Bitmap. On average devices with 1024 size takes about 8 - 10 seconds. How can we reduce generation time?
I am trying to implement a custom QR like the ones provided in the examples (Instagram to be specific) code in Java. I have attempted to use the builder but was not successful.
can any one provide me with examples?
thanks.
Describe the option you are trying to implement
I want to create QR code with smaller positioning markings (the 3 shapes on the top left and right and bottom left)
Is there any way to adjust the size of them and let the content grow a bit more?
Thanks for the library! Awesome job!
i want to store option in room database and also edit the qr code from history
