GDPicture don't recognize some 2D Barcode only if the image is rotated

Post by Erkaci » Mon Apr 16, 2018 11:36 am

Hello,
I have an issue with 2D Barcode (Datamatrix and Qr code) using this configuration :
- GDPicture 12.0.0.65
- C# (.NET Framwork 4.7.1)

Before I post this topic I have read others, but no right answer found.

My Problem is : GdPicture don't recognize this 2d barcode image despite the image is clear, but recognizes the same image when is rotated.
This issue happens with following images but NOT for each 2D barcode.

I have this image :
Image.jpg
When I try this :

Code: Select all

var result = _mGdPictureImaging.BarcodeMicroQRReaderDoScan(imageId, BarcodeQRReaderScanMode.BestQuality) 
GDPicture found no barcode

When I use the rotated image (180 degre, see image below) Gdpicture find the barcode.

The rotated image is :
ImageRoate.jpg
GDPicture result with rotated image is :
Barcode ; 01-ABC-abc-01
Format : 2D - qr 100 / 1

Important : I Use BMP format. Unfortunately I cannot attache my BMP images, GdPicture Editor does not allow me to attach BMP File (Error image extension). I Have converted these images to JPG format in order to attache them.

Thanks for Answer

Eric
