Map sizing: bug or feature?

I'm not sure if this is an unintended bug, or a useful feature that I don't know how to use, so here goes:

I was recently making some maps in Tiled, and sized them to exactly 70 pixel squares so that they'd go right into Roll20 without having to resize them to the map grid. Now, it turns out, if your roll20 grid isn't big enough to fit the map, it'll auto-resize to be smaller. I'm not happy about this behavior, but it at least makes sense. Worse: if you're not zoomed to 100% while dragging the file onto the map, it'll re-scale automatically as well (or at least it did for me).

For the latter in particular, does anybody know if this is an expected occurance, and how to manipulate it to be of advantage?

A map should not rescale and should just edge out of the corners if you haven't set the page size large enough. Are you on the map layer?

I was on the map layer at the time, yes. I tried dropping the file 2 or 3 times with no success until I realized that the grid was too small. Upon updating it, the file dropped at the correct size. Same with the zoom issue - once I went to 100%, it was the correct size on drop.

Strange, I've never seen that before. If Gauss comes by the thread, maybe he'll have a better idea.

To clarify the problem, you were uploading a map into Roll20 and it was resized automatically? This has always been normal behavior for at least a bit of resizing. When you upload an image it reprocesses it to thumb, medium, and max sizes. The max size may be slightly different than the original size (the other two will obviously be different).

If you want it at original size just resize it back to the desired size. You can do this by the scalers or by using Set Dimensions.

Yeah, to clarify: I was uploading a map, and it was reduced in size automatically (didn't run into any instances where it was increased in size). The reduction was fairly substantial, I'd estimate 30% or more size reduction - this may be what you're referring to as 'medium' size. The problem is that I don't know exactly how much it was reduced in size, so I can't exactly increase the size, while Set Dimensions requires more finesse than I have ever managed to have in getting the mouse to highlight an exact square of pixels.

The curious part is that, by adjusting the zoom I was examining the roll20 table at, or by increasing the number of grid squares on the table, I was able to get it to upload at exactly the initial size (or so close that I couldn't tell the difference), once roll20 was done importing it. I only really noticed because I'd taken the time to make a map using grids the same size as roll20 uses, so thought it was odd that I got different sizes after import depending upon the conditions of the desktop.

So, it is uploading images differently based on the Roll20 zoom level?

Set Dimensions is not the Align to Grid tool. To use Set Dimensions right click on the image, go to advanced and select "Set Dimensions". Then input the dimensions of the image (you can find it via the original file on your computer).

Gauss, yes, the image was at a different scale depending upon the zoom I had been using. When I set the zoom to 100%, the next time I dropped the file onto the tabletop, it was at the right scale, as it was the next time I dropped one onto a different page.

Also, you're right, I was thinking align-to-grid! Had no idea there was a true set-dimensions tool, and that will certainly save problems in the future. Thanks!

Hmm, not that I'm likely anywhere near my art quota, but I hadn't thought about that at all. Thanks for the head's up!
