I was able to solve the issue.
The issue is not related to NetBarcode, System.Drawing.Common (atleast on windows). On linux environment we use libgdiplus.
NetBarcode.Barcode.GetImage() creates a bitmap:
var bitmap = new Bitmap(_width, _height);
This by default creates a bitmap having 32bit depth (RGBA).
public Bitmap(int width, int height) : this(width, height, PixelFormat.Format32bppArgb)
{
}
I suspect on Linux GDI+ is no properly handling 32bit color images.
If you explicitly specify bitmap to use 24Bit:
var bitmap = new Bitmap(_width, _height, PixelFormat.Format24bppRgb);
The memory leak issue will be fixed.

Thanks for the contribution. Could you post the memory diagnostics in version 1.4.5?

Currently on version 1.4.5 the memory usage is at 50ish MB. This can further be increased (a bit only) by disposing Font & FontFamily Barcode.cs:55.
Also for future versions of .NET (6 and above) I would recommend switching to SkiaSharp or ImageSharp (SkiaSharp is faster compared to ImageSharp) as Microsoft has restricted System.Drawing.Common to Windows only in .NET 6.
