Code-128A

Hello!
How generate a barcode Code-128A forcibly ?

increase the width of the Narrow space NS and Wide space WS

Thank you for your great work
Is it possible for TZintSymbology.zsCODE128 to increase the width of the Narrow space NS and Wide space WS see the attached image? I need this because when you print the barcode on a small label sometimes barcode reader cannot read it.
thanks again

Micro QR generates the same code for any text

When generating "Micro QR" barcode, the result does not depend on the input string, the same image is generated.
I tested in VCL demo.

Compilation Error

[dcc64 Error] zint_dotcode.pas(35): E2010 Incompatible types: 'PWideChar' and 'string'

The QR code in FMX demo is not working

Excellent component.
When using and compiling the FMX demo (in order to understand how the package will work on FMX, on Delphi 10.4.2), the generated QR code is attached to the stroke of a black rectangle, which is slowing down (and even disabling) the optical recognizing, in addition to many graphic rendering issues.

Compared to the VCL demo that don't have this problem (even coloring the QR code in VCL doesn't affect the result), the generated QR code is rapidly recognized by scanners.

P.S. :

• The scan is done by a phone app.
• The source was not modified, I have just downloaded the package and compiled the demos.

FMX demo

VCL demo

In Delphi 10.3 - 64bits QRcode is empty

Take VCL-QR-EPC demo, add platform Win64 and run : the QRcode shows an empty content.

Print a Code128 with small size

Hi, based on the demo, I am trying to generate a small (3cm) barcode using Code 128. The full size is nice but I cannot read it when with that size. The spacing of 0 and 1 seems not to get correct, seems to cut, I dunno. What properties should I look at to fix it?
Thank you!

Bad height of Code128 and alike

Hi,
First of all thanks for this super port. I'm using the initial version with great joy. Now I'm testing version 25.02.2020:

Comparing the latest version of Zint for Delphi with the previous one I find that a lot Code128 or alike are not taking correct dimensions.
They are cropped in height by some fixed factor. To illustrate please see below - screen dump taken form the supplied VCL demos.
<----- Left shows version: 25.02.2020 Girocode-Generator EPC-QR: -----> Right shows initial version:

The BoxModel does not seem to have changed - so I guess this is a small bug and happens for all 'simple' linestyled bar codes Code128 UPC .. etc?

Would be nice to have that fixed ;-)

Best regards
zEn

can you please fix it to work with delphi 10.2

hi
thank you for you great work.
can you please make the demo for fmx work with delphi 10.2 thanks

Invalid length input on creating EAN13

Hi, creating EAN13 or EAN8, any data get 'Invalid Length Input' error, the demo have that issue too, how to fix?
