Slow VI when inserting a background picture

I am trying to draw a graph on top of an image. (A boat sailing on a map).
When I put the picture as a background on a graph, or behind a graph, my VI slows down. It seems to me like the picture is being updated in every timestep. How can I avoid this? The picture is static, and should only be drawn once.

Each time the graph is sent new data it needs to erase the current plot
before it draws the new data. For transparent graphs, erasing is done
by redrawing the image behind it.
You might want to investigate different formats for the graphics as that
can make a big difference. True color graphics tend to take longer to
draw, though it isn't as bad if it matches the monitor resolution.
If you have additional questions, please provide more de
tails.

Why firefox has slow response when i 'm saving pictures to hard disk?

I have windows 7 64 bit and Mozila firefox ver. 17.0.1. I have the following problem. When i try to save a picture from a site (right mouse click and save as) to the hard disk of my pc, the response of firefox is slow. It takes about 6 to 10 seconds. I thought it was a matter of file size but it proved that it was irrelevant, because it was happening to pictures from 10kb to 500kb. I did the following:
- clear history
- clear cache from firefox and the folder ''cache'' in my profile
- delete the files downloads.sqlite and localstore.rdf
- i changed the ''browser.download.manager.scanWhenDone'' and ''services.sync.prefs.sync.browser.download.manager.scanWhenDone'' to false
- clear the downloads window
- disable all add-ons
After all these, the problem still remained
Then i started firefox in safe mode (help --> Restart with Add-ons Disabled...). The problem still remained.
Then i disabled Microsoft security essentials (real time protection) and windows firewall. I do not have any other anti-virus or firewall on my pc. Nothing happened.
Then i created a new profile (reset firefox). Nothing happened. So, one last attempt was left to do. Reboot with safe mode. So i followed the following steps.
i ran msconfig and disabled ''Microsoft Security Client'' from start up tab and ''Microsoft Antimalware Service'' from services tab. So i did a safe mode boot with network support and windows firewall, disabled. Guess what. Nothing happened.
I noticed that when i was trying to save pictures, during the process, there was a significant hard disk activity (the led indicator of hard disk activity was lighting constantly) and firefox on the left upper corner, shown the message ''not responding'' for about 6 to 10 seconds. You understand that saving a picture of 19kb in 10 seconds is not normal.
Is this problem has to do with the cache? The hard disk is an SSD (solid state drive). Do you think it would be better to redirect cache to memory? (i have 6GB total RAM). This problem was also happening to previous versions of firefox, but i think that with this version, the problem is more frequent. It is not happening with every picture, but it happens with more than 65% of the pictures.
It also happens when loading a web page, but it might be a matter of a heavy web page that uses many resources of my system, during loading. The problem is the same. Constant hard disk activity and it takes time to load the web page. The problem with web page loading, is not as frequent as with saving pictures.
I think it is a matter of cache management. What is your opinion?
Thank you.

The cause to my problem was the jump lists, that Windows 7 introduced. There are two kinds of jump lists, automatic and custom. Automatic jump lists were causing the slow down of firefox through window explorer. Finally it was a problem of windows explorer and not firefox. Windows 7 introduced many new features that cause slow system performance. Anyway the solution to the problem is to follow the steps:
1. Open mycomputer and on the address bar paste the path: %AppData%\Microsoft\Windows\Recent\AutomaticDestinations
2. Press ctrl + a
3. press shift + delete and delete everything inside the folder
I think that the respective jump list of windows explorer is the one that starts with 1b4dd67f29cb1962, in case you don't want to delete every jump list in the folder. If you use firefox, download a file and then go to the above mentioned path and view files by date. The most recent file should be the correspondent with firefox.

Inserting background picture

Hi! Is there any way I can insert a background picture in an applet
instead of using just plain colors.. If there is how can I do it?
Your help is appreciatted.
thanx

You can paint an image right on the background, and than any other things.
That image can be semitransparent for a better look.
you might need to override
public void paintComponent(Graphics)
for doing this

Background pictures do not show up on Singsnap when I open a song to listen to.

When I click on a song to listen to on the site "Singsnap" some of the users have put pretty background pictures on their site but all I see is plain white, the background does not show up....It also does not show up on IE but it shows up beautifully on Google Chrome......Is there some setting I have disabled or what......The HTML is enabled...

See:
* [[Website colors are wrong]]
* [[Websites look wrong]]
* [[Images or animations do not show]]
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

Graphic card problem maybe? Since when I have changed the hard drive to my macbook pro and I installed all the new softwares, my mac is very slow and the screen gives crazy pictures,could maybe be the graphic card, does anybody have experienced this?

after a restart it works for a time, but always slow. I went to the Applestore this afternoon and the made a check and said it would be the logicboard and they would have to change it for CHF 600 and it would be ready in 10 - 15 days

How do I change the background picture that is shown when i start my Mac?

On the iMacs in my school they have a different name for everyone of the after for example the band Queen and then there is a picture on the inlogg screen with queen on it. So then you log in and there is another background picture after that. I Have a macbook pro and I would like to change that "start-picture".
Right now it´s kind of boring and grey. Can you change it somehow?

It sounds like you're using Adobe Send for Outlook. Correct?
Unfortunately, there is no way to change the default text that is inserted into your message. You'll have to change it each time.
I will pass along your request to the Adobe Send team.

HT5361 When inserting pictures in a new mail message using the " photo browser" button I can view and select photos but the " choose " button is gone. What have I done wrong?

When inserting pictures in a new mail message using the " photo browser" button I can view and select photos but the " choose " button is gone. What have I done wrong?

Hi Liz,
Sorry to hear you are having a similar problem. Last night I went to the tool bar at the top of iphoto, clicked on "File", then clicked "Browse Backups" in the drop down menu.    I have an external hard drive that is set up to Time Machine.   The Browse Backups opened the iphoto pages in the Time Machine. I selected a date one day ahead of the day I performed the now infamous update, and it showed my iphoto library as it had existed that day.   I then clicked "Restore Library" at the bottom right corner of the Time Machine screen.   Roughly 2 hours later my iphoto was back to normal.   When I opened iphoto there was a message saying I need to upgrade my program to be compatible with the new version of iphoto(version 9.2.1). I clicked "Upgrade" and within seconds it had done whatever upgrading it needed to do.
The only glitch in the restoration was that it restored the library as it appeared last week, so I no longer had photos I had imported this past weekend.   I simply went back to the Browse Backups in the drop down menu, when Time Machine opened I selected the page showing my pictures from this weekend and again said to Restore Library.   Roughly 45 minutes later the library was restored including the most recent photos.
I am now a happy camper.
I don't know if any of this will be of help to you because your email says you are having trouble with photos imported after the upgrade was performed.   Have you had any pop up notices when you first open iphoto, that tell you you need an upgrade to be compatible with the new iphoto?     If so have you clicked "upgrade"?
Good luck Liz, if you have Time Machine running as a back up to your library, maybe you wil be able to get help there, by following my instructions above.   Otherwise,   good luck with your investigations.   I'd be interested in hearing how you make out.

When inserting a .pdf of a document with a standard white paper color the test and images show up, but the white background is transparent. How do you also make the white paper color show up?

When inserting a .pdf of a document into a Keynote template with a standard white paper color the text and images show up, but the white background is transparent. How do you also make the white paper color show up?

Use the color fill option - select the inserted .pdf and assign a fill color of white to it using the Color Fill Menu on the Toolbar or the Color Picker Palette.
Good Luck.

Why does the screen background picture get reset to default when switching user

iMac with OS X 10.6.8
I have several user accounts on this iMac, each with a different wallpaper chosen from a common folder (library/desktop/nature) in the top level of the hard drive. (Which exists – can always reset background picture from this folder)
When I switch from one user account to another, the wallpaper picture, set on the previous login, appears for a moment and then is immediately replaced by the default blue.
This happens when switching from any user to another. I tried restarting the system but the problem is still there.
This problem just suddenly started and there have been no upgrades or changes to OS X.
Ideas appreciated!!

I've found the answer.
Today, the problem suddenly appeared on my other Mac, which made me look at recent apps..
I installed Team Viewer a month ago, (which is a great app apart from this) so quit it and removed it from the dock. Problem solved!!
The odd thing is that the problem appeared only after I had been using Team Viewer for some weeks.

Contact Picture Low Resolution When inserted from Outlook 2007

-iPhone 3G
-Outlook 2007
When I insert a picture into a contact using the iPhone: the picture is saved as 320x320 in both iPhone and Outlook after sync.
The problem is when I add a picture into a contact using Outlook2007: the picture is saved as 72x72. Outlook automatically resize any picture down to 72x72.
+How can I make outlook insert pictures at 320x320 resolution?+

Welcome to the Apple Discussions.
How are you going about uploading?
Are you digging the files out of the DATA folder in the iPhoto Library Folder? If so, you're using the thumbnails that iPhoto uses for display purposes.
There are three ways (at least) to get files from the iPhoto Window.
1. Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. Show File: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
I suggest you use the File -> Export option and export the pics to the desktop. There iPhoto will make a copy. Upload that, and when the upload is finished you can trash the copy on the desktop - your original is safe in iPhoto.

After rotobrush, how to make background picture appear in the video when exporting it to PremierePro

I seem to have problems saving/using it with premiere pro. it's a 10 second video of myself with 3 pics: 2 that I put in front of the video and one as a background. In after effects, in the bottom left corner box, the 2 pics are above the video file and the background picture is below it. Still in after effects, the background pic is there behind me and the 2 other pictures are in front of my video which is where everything should be, great. When i save it, then export it to premiere pro, the 2 pics in front are there but not the background pic, the background is just my full video as if I didn't rotobrush it. Help??
Also, how can i export the project as a file in Avi, mpeg, mp4...?
Thanks in advance

Hello Mylenium, i do apologize about my ambiguous question. I'm starting to learn how to use it and in some way, i didn't even know what i was talking about myself. But thanks to your help, i now got it.
"When you export an After Effects project as an Adobe Premiere Pro project, Adobe Premiere Pro uses the settings from the first composition in the After Effects project for all subsequent sequences. Keyframes, effects, and other properties are converted in the same way as when you paste an After Effects layer into an Adobe Premiere Pro sequence."
so as it says above, it only uses the initial video. What i did was only render using the rotobrush and i didn't "render queue" the whole project afterwards simply because i didn't know i had to do that. I thought rendering it from rotobrushing it and adding the background effects would be enough.
Again, thank you. and i also learned how to save it in different format, since AVI outputs a huge file size.

Laptop 'hanging' when trying to change background picture

Hi
I've tried to change the background picture under system preferences - desktop/screensavers. When I tried to select a picture from my iphoto-folders the system hung and won't come back at all until I shot it down with the on/off button. I wasn't even able to do a forced quit...
Did somebody encounter this as well?
It actually worked fine again after a restart, but still I think this a strange behaviour.
Mac Book Pro Mac OS X (10.4.7)

If I can jump in here, Jason is asking about background applications of which there are several always running. You can check this by opening Activity Monitor (in Applications> Utilities).
Changing pictures is affected by a number of other applications, including (oddly) the Dock.
When you selected the picture, was it in one of the Original or Modified folders? Try copying the picture and moving it to a separate folder in the Pictures folder and selecting it again.

When i open .jpg picture in photoshop on MAC the the background thumbnail in the layers panel looks like a white box with the brush inside instead of picture thumbnail. how to fix it?

when i open .jpg picture in photoshop on MAC the the background thumbnail in the layers panel looks like a white box with the brush inside instead of picture thumbnail. how to fix it?

Very easy. That means you have a "no layer thumbnails" option selected.
Go into the Layers Panel menu at the upper right of the Panel, choose Panel Options and you will see Thumbnail sizes to choose from.
Select one, click OK.

Background picture missing when post at non .mac-server

Hi, I am new at this so you have to excause me if I ask stupid qustions.
I’ve just made a homepage using Iweb. When published at:
http://web.mac.com/katamaleegarden/ it looks the way I want it to look, when published at:
http://maleegarden.com the background picture isnt there. What have I done wrong?
MiniMac Mac OS X (10.3.9)

Welcome to the discussions, Malee.
It looks like the problem is the name of that image (and one other image on your page AND other images on other pages). .Mac can handle names like these
http://web.mac.com/katamaleegarden/iWeb/7CDA7829-0DE9-11DC-AD00-000D93787A30/Ima ges/balkongfontän1-2.jpg
http://web.mac.com/katamaleegarden/iWeb/7CDA7829-0DE9-11DC-AD00-000D93787A30/Ima ges/Orkidé8-1.jpg
But when you post those to another server, they become
balkongfontaÌˆn1-2.jpg
OrkideÌ8-1.jpg
The easiest way around it is to change those names so that they don't use any special characters, like
balkongfontan1-2.jpg
Orkide8-1.jpg
If you go back through and change your image file names so that they don't have those characters, you shouldn't have a problem with missing images on these pages either:
