So, I've drawn on the map a few time, often by accident. I thus far haven't been able to erase it, and have either had to leave it there, or have the GM erase all freehand. Is there any chance erasers could be in our future? Even an "erase everything I'VE done" would be nice. Cheers, and thanks for having this service available.

If you can select your drawing and move/rotate it around you should be able to hit the backspace/delete key to get rid of it from the tabletop.

theres also ctrl+z to undo the last step you made...but I support the need of an eraser tool

When you're drawing on the tabletop, you are creating a vector-based drawing. Each vector line/shape is a series of mathematical expressions that tells the application how the object is to appear on your screen. This is why your line remains crisp if you increase the scale of your drawing. An eraser tool that you would normally find in MSPaint/Gimp/Photoshop is used for raster-based images, not vector. A raster image like a BMP, JPG, PNG, etc is comprised of a large mass of pixels. An eraser tool is used on raster images to remove said pixels.

Kristin: Could a vector-based drawing be altered by changing the color? If so an eraser could change the color to transparent. The vector line/shape would still be there but it wouldnt be visible. Not quite the same but it could be an intermediate step. - Gauss

If you made the drawings invisible, then you'd have elements taking up RAM that don't actually have to be there. Also it might make selecting elements on the tabletop difficult because you might accidentally select the invisible drawing rather than what you actually wanted. It would make more sense to just select a drawing and delete it. As a player, you should be able to delete your own drawings by selecting them and hitting the backspace/delete key. Is this not working as such?

I was thinking of keeping 1 line of a drawing invisible but I see your point. The reason I was wondering is not because delete doesn't work (it does now) but because if you draw a very extensive drawing then want to tweak it I thought that certain lines would be individual and not part of the whole. - Gauss

Unfortunately, you can't vary the coloring of a single piece of vector drawing. As for tweaking vector graphics, if we had more complex vector spline drawing tools you could yank individual vertices around, manage Bézier curves, and remove vertices/segments entirely. However that's quickly descending into very complicated tools that you would find in comprehensive vector drawing programs like Adobe Illustrator and CorelDRAW.

Not to hijack this topic, but Kristin, I have a post up about the Fog of War and was wondering if yew can shed any light on how it works too? <a href="http://community.roll20.net/discussion/3396/fog-of-war-issue-environment-layer-and-video-chat-fails#Item_1" rel="nofollow">http://community.roll20.net/discussion/3396/fog-of-war-issue-environment-layer-and-video-chat-fails#Item_1</a>

I'll have to check with the Devs on how FoW is handled to give you a better answer on that thread, Cycotix.
