I am sorry for the inconvenience.
For VCL, TRVBitmap is defined in RVClasses unit (and = TBitmap)
For FMX, TRVBitmap is defined in fmxRVClasses unit (as a special class)

I you can create Delphi application with FMX Linux for this OS, am sure that TRichView and ReportWorkshop will work on it as well.
The only specific Linux requirement for TRichView: pango library version at least 1.44 must be installed.

Sorry, the components were not tested on a server environment. However, Linux is supported (FMXLinux is required), and all FireMonkey demo projects for ReportWorkshop can be compiled and ran on Linux. If you do not need a user interface, you can use a non-visual component TRVReportHelper.RichView in...

Run "Install TRichView VCL in Delphi IDE" from Windows Start menu.
It will recompile the TRichView+ReportBuilder integration package.

The advice above works if you upgraded ReportBuilder from another 22.x version. If you upgraded from an older version, re-run TRichView setup.

This example draws line numbers on the left margin. Just make sure that value of LeftMargin property is large enough.
It's only a drawing, so these numbers are not considered as a part of a document.

I am sorry, but additional parameters defining the shift of coordinates were still not added :( Probably, one more custom painting item would be a better solution than modifying OnParaBack. I'll add it in the next update. I can send a beta version to you if you need it sooner; please remind me after...

This code shows how to draw line numbers in FireMonkey version of TRichView: https://www.trichview.com/forums/viewtopic.php?p=45845#p45845 But if you want to implement not only simple text coloring, but syntax highlighting, it is much more complicated task. In TRichViewEdit, you can change colors on...

This code for OnPaint event draws line numbers in FireMonkey version of TRichView. Line numbers are drawn on the left margin, so the value of LeftMargin property must be large enough. The following values can be customized: - distance from the right side of numbers to the right side of the left marg...

Sorry for the delay, an example will be tomorrow.

Text color can be changed, just like any other text attribute.
Line numbers is not a built-in feature but can be implemented using custom drawing events.
I'll provide an example later today.

Do you have RVCamera.Latency = 0?

In the newest versions, these delays can be removed without recompilation. Just assign RVCamera.FFMpegProperty.NoDelay = true.

This is a minor update. See viewtopic.php?t=13096
