image sizing requires image environment

[xronosuf]

Currently, if an external graphic file is invoked outside an image environment, its scaling becomes unpredictable. This should be fixed to have some kind of standardized size or something to allow for some kind of default behavior, rather than having it being entirely arbitrary based on source file information.

NOTE: This is one of the issues noticed via the pdf from the "all examples" repo compilation as part of the full project audit I'm doing.

No, they can be resized by resize box, or they can just have a correct size.

The environment "image" resizes things and centers things.

Wim points out....

\begin{image}[3in]
PICTURE
\end{image}

or

\begin{image}[.6\textwidth]
PICTURE
\end{image}

BUT these options do nothing online... BUT kinda with good reason -- these resizings are for paper page size.
Rather, online you want your image size to be adaptable..

Actually, I think they should do something online - as the \textwidth should be the size of the window width that text can be inside. This is a whole other thing though, as Jim and I have talked about this at some length, and it comes down to how you want to handle dynamic resizing - i.e. if someone is actively dragging the window resize around for an already rendered window (as oppose to different window sizes on different monitors, but those windows themselves are static in size).

Right... that's what the issue says. The "image" environment standardizes the image size - because it resizes and centers the image to a specific size, regardless of the original image file size.

What I was saying, is that all images should have a default image size - say the width of the window or something (what the size is I don't actually care) and then all images should be scaled to that size unless you specify a different size via some kind of resize box. That way you don't get wildly different size images based on the source file's pixel dimensions - which most people don't actually know or notice since most image viewing programs resize the image to a relatively set size and scale the dpi.
