Alternatively;
Is there any command line tool for ARM Linux which could possibly do what I need?
I could use the TProcess approach as well, it works for well for me to do so and fits perfectly within my frame of approaching my requirements.
You could use ImageMagick, it works quite ok on Raspberry Pi, so I would guess it also works with other ARM's
I am looking at GraphicsMagick and it seems interesting and seems to a have a different license than ImageMagick.
I have two new questions:
1. How do I download, install and use GraphicsMagick on Raspbian and then utilize it from my lazarus app? Do I utilize it from the terminal with RunCommand?
2. What license does GraphicsMagick have? I am working on a commercial product so I need to know the license in order to not potentially get sued in the future and cause harm to my company.
EDIT:I found on Google that there is something called PascalMagick, which uses ImageMagick.
Is there a similar thing for GraphicsMagick?
