Hi,
That an old project which should have been deleted. If you open the project group file you see all the demo projects.
I hope it helps!
Sincerly, Edward

This problem is not limited to TestApp!!!
We have use the last version of ZXing (v.3.9.8) to replace an old version (v.3.9.5) in an app and we have the same error: It is impossible to compile the project!!!
At the compilation, we have as result:
[DDC Error] ZXing.RGBLuminanceSource.pas(115): E2003 Identificator non declared: TBitmap [DDC Fatal Error] ZXing.RGBLuminanceSource.pas(122): F2063 ...
So, the conclusion is that the version v.3.9.8 cannot be installed as explained for the old versions or that elements are missing in the new code
Best Regards
Can you download 3.99 ? I released a new version because the last release was a bit behind the repo.
I downloaded it myself and builded all projects in the test solution for Windows32 and Window64. Just for a quick test. That works.
Can you try?

Which version of Delphi are you using?
The error what you get is: [DDC Error] ZXing.RGBLuminanceSource.pas(115): E2003 Identificator non declared: TBitmap
Its defined in fmx.graphics
this is included in the uses clause of ZXing.RGBLuminanceSource.pas with:
{$IFDEF FRAMEWORK_FMX} FMX.Graphics, {$ENDIF}
and this IFDEF is only available as of RAD Studio 11.1
This is because of this commit: https://github.com/Spelt/ZXing.Delphi/commit/129116c9e1ff355714c7504d535ec81e6bfa2f72
It breaks older Delphi versions. Is this something you can confirm ?
I only work with 11.3 and 12.0 so I did not notice it.
There is a new version 3.9.10 which has reverted FRAMEWORK_FMX so it should fix compatibility problems with pre 11.1 versions.
Can you check if this version works as expected on your machine ?
With Delphi 10.4.2, the version 3.9.10 doesn't work: The compilation triggers another fatal error:
[DCC Fatal error] ZXing.ScanManager.pas(11): F2613 Unit VCL.Graphics not found
Thanks. this confirms my hypothesis.
Anyway it seems the $IFDEF FMX does not work. So I reverted this fix to the >= 11.1 Delphi versions
I uploaded a new version.
USAGE
If you use a Delphi older then 11.1 then you NEED to set a compiler Define in your 'project options->Delphi compiler->Conditional defines'. Set this in your target platforms or All platforms. See demo applications.
FRAMEWORK_VCL - this predefined variable is set to true if the project uses the VCL framework FRAMEWORK_FMX - this predefined variable is set to true if the project uses the FireMonkey (FMX) framework
Feel free top reopen if there are any troubles.
Dear sir,
