QR Code encoder library ported to PB

[mk-soft]

Great, thank you very much.
Now no more external DLLs.

Searched for URL example How to find the source code in the forum again

Code: Select all

img = qrcodegen::CreateTextImage("https://www.purebasic.fr/english/viewtopic.php?f=12&t=76558")

Hi iinfratec,
Is it possible to have a pbprogramm which read PDF, PNG,JPEG ?
THanks for answering

[fluent]

Very good job, thanks!
2 questions:
1/ Where in the code could I change the size of a "dot" (or the resulting qr-code image)? I've tried ResizeImage but it produces bad artefacts which often make the code unreadable by my smartphone
2/ Is it feasible to use a "round dot" style? Like in this example:

[Saki]

Hi,
it's not my code, but I'll give an answer.
Technically it is unwise to make it round, because you remove information giving content.
You must set the #Raw flag when resizing and you must not create the images as JPEG, but as PNG or BMP.

Best Regards Saki

@infratec
Amazing work!
Thanks a lot!
It seems does not support unicode characters

Anyway to make it process utf8 correctly? It only works with plain ascii at the moment while the mentioned page at https://www.nayuki.io/page/qr-code-generator-library does work correctly. Example text: ภาษาไทย

[mk-soft]

Part encodeText adapted text (#Mode_BYTE) from ASCII to UTF8.
works fine with my Mobil App "Barcode Scanner"

Code: Select all

; See first post ;)

[infratec]

I updated both versions on the fisrt page.
Also synchronized with the latest github version from 10 days ago.

Your code seems good (as many of your codes).
There is Notepad++ plugin to generate QR of selected text, but it seems really bugged.
May make another plugin of that library

[PeteM]

Anyone know how to change the background colour of the image, or to make it transparent?

[infratec]

Modified the code in the first post.
