    Just to clarify, not 200 dpi (dots per inch), 200 pixels = 5 feet (scale).

    Cool. Look forward to seeing them. As for the VTT audience, you should probably immerse yourself into those forums to get an idea of what is expected and what people want to see.

    Question clarifying...

    If I create my graphics with a scale of 1 inch = 5 feet, and resolution to 200 dpi (dots per inch), isn't that the same as 200 pixels per 5 feet?

    You are over complicating it. As I explained in the reply to your PM, we don't care what the dpi is. We aren't printing it. What is a dot on the screen, how does that compare to a dot on a printer? Just keep it simple.

    Heh. I think the answer to the question is "yes." DPI may not matter to you, but I suspect it might to Gamerprinter!

    Not in this instance. He is talking to me specifically about VTTs. There is no need to print when you are playing directly on the screen, but I get the irony of the statement and his name.

    Info yeah, but technically speaking...

    A digital image is measured in pixels. When a pixel is printed, it is represented by a dot. Therefore dpi and ppi is the same thing - one in its digital format only (pixels), the other in print (dots).

    All graphics are measured interchangeably as dpi or ppi - I've got software that refers to both.

    A 200 dpi or ppi image is measured as 200 x 200 dots or pixels. Most software I use only refer to dpi, even when an image is never intended to be printed.

    So the issue is semantics. Unless you've got some other specific way to describe 200 pixels = 5 feet, there's only one way for me to make it.

    So I do believe I am correct. I am not making it more complicated. The software I refer to mentioning ppi was Micrografx Picture Publisher and it nolonger exists. All other graphics software refer to dpi interchangeably with pixels.

    Its a simple question.

    Nice work GP...I'm also quite thoroughly impressed with the exterior map...The interior map shows a LOT of work done, but for my own tastes it may be a wee bit too texture heavy...I'm not saying thats a bad thing, as I'm more of a minimalist in my approach to mapping...I definitely agree that these would go really well with VTT.

    As for the dpi/ppi/200 argument...there is no argument really...200 pixels per 5 square feet = 200 dpi scaled print for D&D size miniatures = good for everyone
