I have some issues related to some QR code generation and questions.
1. QR code generation speed
I have tried to make QR code images from a binary file.
Therefore, I made several large QR code images with set CodeText to the nearly maximum capacity of QR code.
But, the speed of barcode image generation was very slow;
It was almost 2 minutes and 6 seconds in generating 11 large QR code images.
I tried with J4L’s Barcodes for .NET with almost same conditions;
It was only 18 seconds in generating same QR code images.
I think that your product is superior to J4L’s because J4L’s is lacked in many features and stabilities but the difference between Aspose’s and J4L’s are too much.
I hope that the performance will be improved at future release.
2. Some questions about QR code
I know that the capacity of QR code is 4296 at alphanumeric mode and 2953 at binary mode.
But, I did not find the property to set the mode of QR code.
And, I have a question about mode.
Are only alphabets and numbers permitted at alphanumeric mode?
If I set code text to a string containing “/” or “?”, must it be binary mode?
I think that is right because the max capacity seems to be accorded with 2953 when I set code text to the string containing “/” or “?”.
What I know really is how long I can insert at QR code image with Aspose Barcode.NET and how I set CodeText to byte array directly.
3. The issue about blank barcode image is generated when code text is set to over maximum capacity.
When I set code text to a string of 3000 length (i.e. over 2953), generated barcode image was blank and only became a white rectangle. The library did not alert any error.
If you could take a few minutes to answer my questions, I would really appreciate it.
Thank you in advance for your help and apologize for my short English skill.
