mouse zooming

[gubment_cheez]

hey, when zooming with the mouse (by holding the control key down and using the scroll wheel), it zooms in by 12%; however it zooms out by 10.71875%

here's the zoom levels I got with PDN

0100	0112	0125	0140	0157	0176	0197	0220
 0247	0276	0310	0346	0388	0434	0486	0545
0610	0683	0765	0857	0960	1074	1203	1348
 1509	1690	1893	2120	2374	2659	2978	3200
 1447	1621	1815	2033	2277	2551	2857	3200
0584	0654	0733	0821	0919	1030	1153	1292
 0235	0264	0296	0331	0371	0416	0465	0521
0094	0106	0119	0133	0149	0167	0188	0210

I checked this with an Excel Spreadsheet, shown here, in case someone wants to verify my work. the function takes the previous number (in column 1-the zoom levels list, one row above the current) and adds or subtracts the percentage (in column 02, row 01 and row 33 respectively) to figure out what the current zoom level should be. I chose this method to detect any rounding error because that's what I originally thought the problem was

and when PDN isn't at a square zoom level, it stretches some pixels, but not others, which paints a distorted image on the screen.

Is there supposed to be a question, or are you just stating the facts as you see them ... ?

[gubment_cheez]

oh, yeah. forgot the question. would it be possible to keep the zoom on solid numbers, like 100, 200, 300 400, 500, like the zoom tool/toolbar?

[david.atwell]

The zoom is a function of your personal mouse's click wheel. It's not something PdN makes up; Some people's scroll wheels scroll at 10%, some at 15%, some at 12%. Mine tends to scroll somewhere around 17%, but it's not constant.

This has been asked before. Different mice have different sensitivities, and trying to adjust to fit everyone's would be close to impossible.
