How to increase brightness

Hallo. I have this sprite object:
public var mioPosto:Sprite = new Sprite();
In this object i am drawing some shapes based on input coordinates:
this.mioPosto.graphics.clear();
this.mioPosto.graphics.lineStyle(1,0xFFFFFF, 1);
this.mioPosto.graphics.beginFill(0x00FF00, 1);
this.mioPosto.graphics.moveTo(this.mioPostoStruttura.c1x, this.mioPostoStruttura.c1y);
this.mioPosto.graphics.lineTo(this.mioPostoStruttura.c2x, this.mioPostoStruttura.c2y);
this.mioPosto.graphics.lineTo(this.mioPostoStruttura.c3x, this.mioPostoStruttura.c3y);
this.mioPosto.graphics.lineTo(this.mioPostoStruttura.c4x, this.mioPostoStruttura.c4y);
this.mioPosto.graphics.lineTo(this.mioPostoStruttura.c1x, this.mioPostoStruttura.c1y);
this.mioPosto.graphics.endFill();
How can i increase the brightness of each shape??.. I don't know the property and i cant' find it... Is there a way?.. I wish they are much more visible..
Thx for all
Max

you're going to have to be a bit clearer on what you mean by "brightness" increasing brightness in terms of the colourspace concept will make the shapes look paler. perhaps you mean contrast? using 00FF00 really should be visible enough as it is.
As this is not strictly a flex issue oyu might try actionscript forums instead or take a look at the ColourTransform class
maybe this would help? http://www.flashwonderland.com/color-matrix-filter/contrast.html although not sure it will have a lot of effect on a 0x00FF00

  • How to increase brightness of LR4 cropping grid

    The grid is hardly visible in all outdoor images, except those with very dark backgrounds or shadow areas.
    How do I increase the brightness of the grid?

    There isn't a way but you can...take note of your exposure slider setting, crank it down a couple of stops, tweak your crop, return your exposure setting to where it was.
    Not elegant but I use it outdoors on my laptop when it is too bright to see what is going on.

  • How to increase brightness in Windows 7 and for the Option sceen?

    I have an 15" early 2011 MBP with Snow Leopard and reccently installed 64-bit Windows 7 Pro using an upgrade disk I had. Apparently the backup/upgrade disk would allow me to do a clean install despite not having a previous version of windows to base it off of now that XP is no longer supported.
    I had no initial problems installing Windows and getting the bootcamp software fully updated (3.2 I believe,) but while I was in the process of updating all of my windows software things started getting messy. I managed to update some windows functions, but eventually I ran into a real problem after downloading what I believe to be a service pack (not sure which one) that was recommended by the windows updater. After downloading the update, the computer needed to be reset.
    Upon resetting the laptop, I found that the option screen that lets you choose which partition to boot into is completely black. I can tell that the display is on because the screen is somewhat brighter than when the laptop is off, but I can't see anything.
    For grins, I tried seeing if hitting the right arrow key and then enter would take me to my windows partion, which it did. The loading screen (with the windows icon approaching and illuminating) is completely fine; however, after that loading screen, the screen appears to turn off (nothing, zilch, nada.) I let it sit there for about 5 minutes or so and still had nothing. Upon hard-resetting my computer, I found that when I tried booting windows again it gave me the options to boot into safe mode. Safe mode works and gives full brightness, normal mode does not.
    I looked on the forums and saw that deleting C:\WINDOWS\SYSTEM32\DRIVERS\ATIKMDAG.SYS could fix the issue. I downloaded Paragon, mounted the bootcamp partition and removed the offending file from my mac partition.
    The option screen was still black, but the login screen appeared after the computer tried to finish patching (the service pack patch failed.) The problem then was that the screen was incredibly dim at full brightness. I had control of the brightness settings via fn+f1/f2. All it took was dimming the screen 3 notches in order to make it go completely black. I logged in and tried updating the radeon video card, reset the computer and found myself back at the off screen issue mentioned earlier after the windows loading screen.
    I have yet to check, as this process has been extremely tiring and annoying, but I think I can fix the completely dead screen by removing the driver again. I gave this long story to show what I have done so hopefully I cam get a response I
    My burning questions are:
    What do I need to do to get the screen back to full brightness when I do get my laptop to boot into windows successfully?
    How do I fix my option screen to actually show up again instead of blindly picking the partition I want to boot into?
    Are there any windows updates that I need to avoid for 64-bit windows 7? I'm guessing whatever service pack it was I downloaded is one of them.

    I don't use the search engine, so I'm afriad I don't have direct experience here.
    What I'd probably do is modify the app so that it looks at the Host data to determine which directory it should point to for graphics, formatting, etc. You could also use the obj.conf with variables to pull graphics from directories appropriately branded. Something like:
    1) Create "additional doc directory" for images
    2) Find the entry in the obj.conf that points to the new directory
    3) Modify the path to something like /path/to/$host/images
    4) Make sure you create directories like:
    /path/to/foobar.com/images/
    /path/to/www.foobar.com/images/
    /path/to/baz.com/images/
    /path/to/www.baz.com/images/

  • How to increase "brightness" of Display Screen on ...

    Hi I have just up-graded to to a Nokia 5800 XM which seems the "bees knees" to me as I have never had such an all singing and dancing mobile phone before (had a 6230i about 5 years as my up-grades usually went to daughters or not taken but 6230i lost it's life a couple of weeks ago when it toook an accidental dip in the washing up bowl  *)   )
    I like lots about the new phone , especially the QWERTY keyboard - I can actually do texts now as the old way on key pad took me forever!  Oh and handwriting tablet is great - can even write texts!
    The only down side is the "display screen" seems rather dim in average to bright daylight ( I am not visually impaired not particularly mentally impaired either as a teacher) SO DOES ANYONE KNOW HOW TO MAKE THE SCREEN BRIGHTER?
    Thanks Bri

    There's a setting in the BIOS - Display Brightness (high or normal).  Try setting it to high.  If this doesn't work, you may have a problem with your display.

  • How to increase the battery life of your N series ...

    What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
    Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
    So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
    First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
    Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
    Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
    Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
    If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
    To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
    You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
    The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
    The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
    To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
    Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
    It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
    Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
    Hope this helps.

    no keffa it is a cop out from nokia

    the n95 battery is atrocious
    dont change the post content as the title is 'How to increase the battery life of your N series device'
    your talking about nokia phones specifically
    the networks are not to blame
    they do not make the handsets : Nokia do !!!!!!!!!!
    I'm going to choose my words carefully here...
    I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
    However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
    What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
    They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
    Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
    Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
    Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
    So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

  • How to increase your battery health - anyone with similar experiences?

    this is my very own self made instruction of "how to increase your battery health"
    it is the procedure how i have done it serverall times on my powerbook g4 12".
    my stats: 374 cycles, health 86% (3790 of 4400mAh)
    age of my mac: 57month (battery bit newer)
    **if you to try this: it is on your own risk!**
    **this may not be suitable for mac newbies**
    **be sure to read this twice before you do it once!**
    you will need:
    -a pocket lamp or comparable light (to see anything on your sreen when it is dark --> light from the back through apple logo)
    -coconutbattery (coconut-flavour.com/coconutbattery) or comparable programm to track your battery information in realtime
    -activity monitor
    -cool enviroment (to ensure your fans don't have to work that much)
    -some time and patience
    the intructions:
    step1: load your mac until the orange light turns green
    step2: disconnect the power adapter
    step3: use your mac until 15-25% battery life (track this information in your menu bar)
    step4: slow down your activities. the order of the following actions depend on your usage of your mac:
    __close programms that use lots of cpu/gpu to ensure the fans slow down to 0rpm (!!)
    __turn off everything that needs battery power: airport / bluetooth / speakers / etc.
    __eject dvd or cd
    __close all programms with important data
    __eject idisk / .dmg files in your finder (this is not only a matter of data security)
    __dissonnected from peripherals such as ethernet / internet / mouse / keyboard
    __use lower brightness level
    __open activity monitor to ensure that your hard drive activity is very low, may be you need to close more active programms, close activity monitor when hard drive activity is very low
    __open system preferences >> energy saver preferences >> choose longest battery life
    when your are ready with those actions go on and ensure you are able to connect to power adapter with your mac quickly (be able to charge - don't do it yet!)
    step5: be patient. now it should take some time until your battery level goes down to 3-5%
    now there should be no programm running.
    do not open any programm now!
    do not have a look at your dashboard!
    now your mac should be really quiet:
    -no fans (0rpm!)
    -nearly no hard drive activity!!
    -->> if this not the case break go on with step 11&12, try again in a week or two
    -->> if you are ready go on with step6
    step6: open coconutbattery und use the lowest brightness level
    play with your trackpad to ensure your screensaver won't start. waste time until you are at 1-2% battery life.
    step7: take your lamp and spot through the transperent apple logo, position your coconut battery window somehow that you can see the current battery charge und the maxium battery charge in the spot of your lamp through the apple logo.
    step8: go from the lowest brightness level to the level under the lowest brightness level (a dark screen)
    step9: watch your current battery charge carefully und keep on playing with your trackpad to ensure your screensaver won't start.
    step10: there is kind of battery buffer made of approximately 1% (once when my "current battery charge" was 3624mAh and this kind of buffer was at 36mAh)
    to empty this kind of battery buffer takes much longer as you might expect!
    when your current battery charge turns under this kind of battery buffer, your maximum battery charge should change. hopefully it is higher or stays the same. when it is lower now: i'm sorry - i have warned you. may be you have to go through this 'how to' more carefully!?
    step11: plug in your power adapter before the battery is cero!
    step12: load until the orange light turns green
    step13: if it was helpful do not repeat it more than once a week, better once a month

    anyone with similar experiences about increasing battery health!?
    (yes, i'm sorry for my poor english, i've tried my best)

    Me too! My battery lasts for 10 minutes. It is awful and I am on my 4th power adapter since they keep breaking too.
    From coconut battery: Maximum battery charge 310mah, original 4400, age of mac 45 months, 140 cycles.

  • W540 with Apple 27" Thunderbolt display - how to control brightness?

    Hi everyone-
    I have a colleague's hand-me-down 27" Apple Thunderbolt display that I wanted to try to run on my W540, which runs Win7 x64 Enterprise.
    I connect to the notebook port (do not see this port on my dock) and basic display appears.
    I cannot control the brightness and the display is at a dim default level.
    I tried two general online recipes to fix this situation - 1) installing Bootcamp services [1] and using the control panel and 2) installing a BrightnessController windows program [2] that is supposed to talk directly over the Thunderbolt device connection.
    I could not get either one to work - Bootcamp services did not show a Brightness tab (it has that capability if the stars align) and the BrightnessController app said it could never detect the display device.  I uninstalled the Bootcamp sevices to try to allow this app "exclusive" access to Thunderbolt devices, but it didn't make any difference.
    The only other pieces of data I have are:
    - in the Intel Graphics control panel app, it recognizes the display as a "Thunderbolt display".  I can play around with some color balance settings, but these don't seem to be talking natively to the display (increasing brightness results in terrible washout of colors)
    - in Windows Device Manager, my display appears as a "Generic PnP" monitor.   I've never seen it described as something Apple-specific (maybe due to no specific Windows driver for it - even after Bootcamp services install)
    I've read bits and pieces of Thunderbolt display issues on Lenovo forums, but nothing seemed to match my question for native hardware brightness control.  
    Does anyone have any useful inputs - success stories, ideas for things to try?
    Thanks!

    Solved!

    Also! Just tried installing the "Intel Thunderbolt Software" that was available from Lenovo System Update (did not see that before) - once installed, I could use the Brightness Controller app [1]

  • Qosmio X500 - How to increase the screen resolution?

    Hi,
    Does anybody know how to increase the screen resolution? My qosmio X500 is 1920 x 1080 and I want to raise it to 1920 x 1200.
    Thank you/Red

    Hey
    1) I think the screen brightness is about 180 nits for this qosmio model. If I change the graphics card, can I increase the brightness to 300 NITS levels? If yes, which card do you suggest? If not, how can I achieve this?
    2) When I view the screen in 100 % magnitude, then the texts are too small to read. But then when I view the screen in 125 % or higher, then the texts go blurry. Is there a way to avoid this?

  • How to Increase Number of Images from 500 in a LR3 Flash Gallery

    I noticed people asking (and I myself needed to know) so I thought I would explain how to increase the number of images (from 500) in a Flash gallery in Light Room 3
    1. I exported a Flash gallery from LR3 and it capped the gallery at 500 images.
    2.  Because I had roughly 600 images to put in the gallery, I exported the  remaining 100 as a separate flash gallery. (Going ahead and exporting 2  galleries will save you headache in a later step)
    3. I combined  all the images folders (copying "large" images from one folder to the  "large" folder in the gallery I want to upload to my site, etc.) so that  the files are all in one location.
    4. The next step is to  increase the gallery maximum in the code. Access (from the exported  gallery) GALLERYNAME/resources/mediaGroupData/group.xml and open the group.xml file. The line of code you will be changing is <media totalGallerySize="500"> Change the 500 to the number of photos you want in the gallery.
    5.  This next step isn't too complicated, but it is specific. You know have  to tell that flash file to look for the images you just transferred to  the images folder. The best way to do this is to open the group.xml file  for the second gallery you exported. Copy all the code beginning with <item>  to the bottom of the page. This code tells the gallery to look at your  specific images (Note: you'll notice within each item the names of your  image file)
    6. Return to the (other) group.xml file of the gallery you plan to use (with all your images in it). Scroll to the bottom and erase the lines </media> and </mediagroup> becaue you will repaste them in a moment. Next, paste the copied code there.
    7. Save & check your browser!
    I hope this was clear...please comment back and I'll clarify if needed.

    The standard status overview iview of the team workset has 5 rows and we have to scroll using the arrow buttons to select/view a request.
    Now can anyone explain me how to increase the number of rows in this iview? Is this somthing that has to be accoplished through web dynpro customization?
    I checked the options in iView property and do not see any option to increase the number of rows.
    please help
    Thanks

    Hi Micheal,
    Well, I am not really sure, if you could accomplish this using customizing, but I am sure that you can accomplish this using the JDI. Well, you can extract the application's source code using JDI and then change the required display rows property and republish it.
    Am not really sure if this is suggestable method for this requirement,but it can be achieved using this JDI stuff.

    I think the standard template in 2004s is named 0ANALYSIS_PATTERN. You can find it in Web Application Designer, open, and search for the technical name. If you want to change the number of rows or columns, you can find this setting near the bottom of the XHTML view of the template:
    <bi:BLOCK_COLUMNS_SIZE value="4" />
    <bi:BLOCK_ROWS_SIZE value="17" />
    Then just save, and ignore the error messages.
