Render Large PDFs eg 1.5x2meters to Image at 600dpi not possible

[cyberchen123]

Is there anyway this could be done? For smaller PDF like A2 its working, but at bigger Formats System.Drawing seems to die. Is it possible to use a alternative to Systen.Drawing? Thx U Rock 🥇 :)

1500x2000mm = 59.05x78.74 " x 600dpi = 35430 x 47244 pixels image.
at 24bit RGB Image, 3 bytes per pixel image memory is required.
If you do the math, you need 4789 MegaByte of RAM, or 4.7 GB!
There is no way .NET GDI subsystem or any 'normal' program can fit that into memory.
Those size images are printed in "stripes" by high end RIP Software with a 5 digit price tag...
