move problem

JoseyWales · Postby **JoseyWales** » Mon Oct 27, 2014 7:41 am

when i try to move text by holding left mouse button, sometimes it jumps around and moves very far. there is not a steady movement to where i want. the more complicated the text, the slower it moves and jumps more. what would cause this? i've been careful to stay off move bars. i'm using a wireless mouse with new battery. thanks

I usually find that "jumping around when dragging" behaviour is caused by snapping. Try toggling snap by pressing "%" or by using the View > Snap menu and see if there is any difference.

JoseyWales · Postby **JoseyWales** » Thu Oct 30, 2014 11:25 pm

i have disabled all snap functions. when i'm moving a text, it will jump completely off page. it does the same thing when moving gradient pointers. seems it always moves down to right.

Hhmmm.... I would have answered just what Xav said..... Hhmmm.

Is the object you're moving purely text? Has it been grouped with anything? Have you applied any filters? Converted to paths? Applied LPE?

Have you only used text and gradients, and those are the only culprits? Or do other objects behave like this too? Are tiled clones involved?

It might be faster if you can provide the SVG file for us to look at, instead of asking so many questions

just text but has been converted to paths and interpolated to make 3d text. any object i try to move may jump too far. the nodes in gradients jump too far when i'm trying to adjust their position.
i've only asked 2 questions.

Oh no, I'm sorry!! I meant it might be easier if you could provide your SVG file for us to look at, instead of us asking you a million questions! After a certain point, a guessing game can go on forever. So us being able to look at your file would be much faster. I'm sorry for being so vague.

"Any object...may jump".....hhmm.... So that would indicate the issue is not specific to text or anything you might have done to it.

Usually some kind of jumping behavior is related to snapping or spiro splines. I can't think of anything else that might cause this, at the moment.

Would you mind attaching your SVG file? Or maybe someone else has an idea??

JoseyWales · Postby **JoseyWales** » Sun Nov 02, 2014 12:21 pm

it says my file is too big to attach. it's only 5 words but some are interpolated.
also, when i click and drag a box to make a selection, sometimes it even jumps off the screen.
i have an Intel Core i7 processor 64 bit, 4gb ram. reckon it doesn't like 64 bit?

Hello
JoseyWales,
First, I was thinking that the problem was your wireless mouse according for the first information you provided. Since I saw that others were giving good advices, I didn't say anything

But now you say:

Brynn is right... we are playing the One Million Question's game. It's neccesary that you PROVIDE the problematic file. You can ZIP the file and attach the ZIP here, or you can provide a link to dropbox, google drive or any other on-line storage service.

More questions
-You are using a Windows Operative System, right? (Win XP, Win Vista, Win 7, Win 8)
-You are using Inkscape 0.48.5 for 32 bits architecture? You should know It can also be used in 64bits architecture
- You have changed your wireless mouse to one with a chord?

Greetings

Or maybe some soothsayer have guessed what is your problem?? :roll:

JoseyWales · Postby **JoseyWales** » Sun Nov 02, 2014 1:29 pm

zip file attached.
i have 5 or 6 different files and they all do the same.
i have tried a corded mouse with same result.
windows7
0.48.5

Seems the 3d shadow creates many objects that slow down the screen redraws. Plus, the big one was duplicated, doubling the slowdown. Total count of gradient objects was about a hundred.

I combined the shadow objects on each word and cleaned the document... much better size and performance.

Open the file and unhide the top layer to see the result being almost indistinguishable from original. (after making the background black...)

JoseyWales · Postby **JoseyWales** » Sun Nov 02, 2014 7:26 pm

yes it does move faster but it still occasionally jumps down and to right about 200 pixels each way. when i draw a box around an area to select objects, seems it doesn't jump as much if i start at the right side and drag to left. seems it shouldn't make a difference.
i should use layers but i'm just now learning inkscape and in a hurry.
THANKS for your help.

tylerdurden · Postby **tylerdurden** » Sun Nov 02, 2014 10:22 pm

For incremental movement you can also use the alt+arrow keys.

I use layers to isolate elements in troubleshooting. They are also helpful in design, but not necessary.

tylerdurden · Postby **tylerdurden** » Mon Nov 03, 2014 12:20 am

P.S.

I can't replicate the issue with the file I uploaded, is the issue still there for you when using the file I uploaded?

Also, when I stated combined, I meant using the Menu: Path>Union after ungrouping the 33 objects forming the extruded "shadow". Similarly, "cleaned" means using Menu: File>Clean up Document.

Edit: corrected "Combine" to "Union". TD

JoseyWales · Postby **JoseyWales** » Mon Nov 03, 2014 12:48 am

still have problem but not as bad. i never used Combine, only Union before interpolating.
i don't see Clean up document.

My machine have an AMD Phenom(tm) II P920 Quad-Core Processor

So, for many people it's very OLD.

Even manipulating the file edited by tylerdurden, I note some delay between the position of the mouse and the position of the selection, the operation of moving objects with the mouse shows delay.

I guess this behaviour is what you are describing along this topic. Sadly, I consider that normal. It may not only be the responsability of inkscape. I don't know but Inkscape may work better ( without delays) in a Linux Operative System. Maybe some maintenace is needed in my machine as in yours. At this point it could be better to contact to the developers:
https://inkscape.org/en/contribute/report-bugs/

Some advices?: all the written before, by the other users, and always clean (vacuum defs In MENU>>FILE), organize, think in what are you doing.

My mistake, yes, Union.

Menu: File>Clean..
Menu: FIle>Vacuum Defs

Same function, different label:

I do see some very slight lag, but not so much to describe as jumping, particularly as using slow drag for fine positioning, where keystroke nudges will be very effective and measurable.

P.S. I am running on a P4 2.8Ghz pentium laptop.

Oooohh, so that explains the "jumping"! AND the other problem too!

Good job guys!

It's because the drawing size is challenging your memory (RAM). You drag the object, but it takes Inkscape longer to re-draw the object in its new position, because there's not enough RAM to do it quickly. So there's a little lag time. Somewhere around here I wrote some tips for getting the best performance out of Inkscape. I'll search it out and post a link. Note the the upcoming new stable release (in the next few months) 0.91 will have a new renderer which will improve a lot of these performance issues..... Well, at least until we start to draw even larger images!

JoseyWales · Postby **JoseyWales** » Mon Nov 03, 2014 4:30 am

no, i'm not talking about the lag time to redraw. i understand that and it doesn't bother me. i worked with ACAD with some of the first computers 35 years ago...talk about a delay, lol.
i have a fast processor, 860@2.8ghz, and 4gb of ram so the delay is minimal. the cursor jumping off the screen is the problem. it's especially irritating when trying to set a gradient. it's like inkscape doesn't know where my cursor is located at all times. that might explain why i can't always select a tool on first try. wonder if there is a test for that?

hulf2012 · Postby **hulf2012** » Mon Nov 03, 2014 6:58 am

Back to the start again! :roll:

... Someone mention, in other topic related with your problems, something about Input Devices (in Menu>>File>>Input Devices) but you haven's say anything.
... Or maybe could it be even the surface behind your mouse!!.

But as you tell us, it's not a problem of Inkscape, because it's not reproductable on other older machines. It's something wrong with your system. Do your check list again.

mmm... what could it be? :?:

tylerdurden · Postby **tylerdurden** » Mon Nov 03, 2014 7:59 am

Pre .91 relocated menu:

Menu: Edit>Input Devices

JoseyWales · Postby **JoseyWales** » Mon Nov 03, 2014 10:01 am

i downloaded software into my old computer, drew the same text and everything works perfectly. it's a 10 year old computer running vista with only 2gb ram.
on problem computer, i checked input devices and unchecked pressure sensitive pad and saved. it says i'm using core pointer. also changed/lowered screen resolution. i still have same problem. my processor has 8 cores. i'm also ran malware scan with no problems.
i uninstalled again, installed 0.91pre2, checked input device settings and everything looks just like your picture.
still same problem.

Postby **brynn** » Mon Nov 03, 2014 2:21 pm

Well, I do agree that since it's not reproducible for us, that it's probably something on your end. But it is intriguing! I'm always up to learn new things.

the cursor jumping off the screen is the problem.

Does the cursor only jump off the screen when you've clicked on something (object or gradient handle)? Like does it only happen during a "drag" movement (with mouse button pressed)? Has it ever jumped off the screen with nothing "attached"?

I seem to recall seeing some Windows option, on my old XP machine, where whenever you press....I can't remember if it was press any key, or if it was only the Ctrl key. But anyway, that would cause the cursor to jump to the center of the page, or the beginning of a line of text.....or something like that. I think that was probably a more helpful feature in the earlier days of computers, than it is now. I don't think that could be happening for you, because bottom right would be an odd place to want the cursor to go to. But just a thought.

If someone else mentioned this already, I apologize. Unless you change Inkscape Preferences > Filters > Number of Threads, Inkscape doesn't use all the cores. That may improve the performance a little. There is a 64-bit version of one of the 0.48x releases. (I can't seem to find my link at the moment -- Partha.com, I think.) As far as I understand, it should be identical to 32 bit, but it is called "unofficial". But I think with 0.91, we will have official 64-bit. I could be wrong about that last sentence, but I see the files on SF.

JoseyWales · Postby **JoseyWales** » Mon Nov 03, 2014 9:33 pm

it only jumps while i'm holding left mouse button and dragging and it's always down and to right. that's what doesn't make sense to me. why is it always in same direction? i've never had this problem with other drawing packages such as Acad, Solidworks, etc. i may try loading it on another new computer.

tylerdurden · Postby **tylerdurden** » Mon Nov 03, 2014 10:17 pm

I'd start fiddling with the usual suspects like hardware acceleration, write combining, pointer dynamics, embedded scroll, etc.

Is this a touch-screen?

JoseyWales · Postby **JoseyWales** » Tue Nov 04, 2014 12:49 am

update - SUCCESS...finally.
problem was due to display size. i sit far from monitor so i had display size set to 150%. i changed it 100% and 125% and tried it on both sizes. everything works perfectly with both sizes. it also cured my problem of not being able to select different tool buttons. they select on first try every time. i don't know if inkscape can be made to work on 150%?
anyway, THANKS TO EVERYONE FOR YOUR HELP. now back to fun working with inkscape.
sorry i was so ignorant.
