How can I create a gradient blur?

I want to create a blur effect that starts from one edge of a photo and gets stronger (more blurred) as it goes away from that point. This specific effect only needs to travel in one direction, so it doesn't need to be circular.
I don't want to use the method of creating a second copy of the photo on a separate layer, blurring it, and using a gradient on a layer mask, because this doesn't achieve the effect I'm looking for, since you can still see some of the non-blurred image under the blurred one.
Can anyone help?

>What I don't understand is why the original poster said Ho's method worked great, when the method gives the exact same result as the method he mentioned he didn't want to use?
I'm not sure of the reason, but it didn't produce the same results. Just to clarify, the image I was using had text in it. When I used the method I mentioned in my first post, I saw the blurred image, but right at the point when the opacity was around 50% I could still see the completely unblurred image underneath (completely clear and readable text), creating a sort-of glow look around the text.
When I used the method that Ho suggested, the text simply becomes increasingly blurred as you look across the image.

How can i create a gradient with four colours that graduate from the four corners of a rectangle?

I've been trying various ways of doing this and nothing's worked so far; I've tried blending two gradients, tried blending four different colours but no luck with that either.
What I'm looking to do is exactly what is displayed when you double click on the colour picker and you select R, G or B. Any help will be much appreciated.

I'd tried using two linear gradients but it didn't give the results i wanted, but i've sorted it out using gradient mesh. Thanks!

How can I create a scrolling effect where when the user scrolls down the image will blur out?

How can I create a scrolling effect where when the user scrolls down the image will blur out?

Hi there,
You can create a scroll motion where the image will fade out on scrolling, you need to use the Opacity tab under Scroll Effects Panel.
If you particularly need the image to be blur out, then you need to edit that image in any image editing program and make one copy of that image as blurred, then place both images (actual and blurred) on that page and use scroll motion or fade option to replace images.

How can I create a new layer that is a gradient?

Hi, i'm very new to photoshop scripting and am having some trouble.
I'm looking for a way to take an image i have and set it to have a gradient opacity as it approaches the middle, my thought on how to do that was to just create a layer that is a gradient from top left to bottom right and then attach that as a vector mask.
Any ideas on how I could create this gradient layer in script, or a better method of doing this opacity gradient?
Thanks in advance,
Levianth

You could try this:
// 2012, use it at your own risk;
#target photoshop
if (app.documents.length > 0) {
var myDocument = app.activeDocument;
var theLayer = myDocument.activeLayer;
if (theLayer.isBackgroundLayer == true) {theLayer.isBackgroundLayer = false};
// create gradient layer;

How can I Create a white hot spot.

How can I create a white hotspot in an image, i.e. A bright spot with feathered edges for a figure to walk out of, a bit like a sun?

Create new layer, make an eliptical selection, and fill with the colour of choice. A muted yellow perhaps.
Use a high value Gausian blur to soften and feather the layer. High values of blur will make the flare very thin, so if too thin, duplicate the layer.
Use Free Transfor to size and shape the flare.
or
Select the figure, and copy to a new layer.
Double click the new layer to open Layer Styles, and use Outer Glow, and some inner glow. This is by far the better option as you can control the inner and outer glow independantly.
or
Open a new document with a square aspect ratio. Make it at least as big as the other image.
make a new layer, and make foreground colour yellow, and BG colour white
Go Filter > Render Fibers. Use full strength, and a lowish variance. You are looking for strong, closely spaced vertical streaks.
Now go Filter > Distort > Polar coordinates. Make sure Rectangular to Polar is checked and OK it.
Duplicate the layer to your other image document, and place behind the layer with your figure on it.
You can play with the flare layer with curves, or maybe add a wee bit of blur and then harden with curves or levels
If you want the flare layer to overlap the figure a bit, Ctrl (Cmd) click the figure layer to load it as a selection, and add a layer mask to the flare layer. Move the flare layer above the figure layer. Now feather the layer mask, using the Mask Properties panel, or use Mask Edge options in the Mask properties panel to expand, or contract the mask.
Good luck, and let us see the end result.

TS2756 How can i create a new usb connection (service) on my iMac for sharing internet from my iPhone5 ( i seem have to deleted it )

How can i create a new usb connection (service) on my iMac for sharing internet from my iPhone5 ( i seem have to deleted it )
i know its not a problem whit my carrier o data plan or sharing preferences on the ipone because when i use it un my laptop it works perfectly through
the usb and even works on the Imac through wifi and bluethood tethering but NOT through usb!!.
the problem is that trying to make it work i deleted the "profile" usb iphone on the network prefereces panel. Now i only have 3 options: ethernet / wifi / bluetooth
but not the usb iPhone i used to have.
And when i try to add a new one i dont get a USB option.
can some one help me please??
this is how it looks (after the bluetooth PAN i used to have USB iPhone option)

The question would be more appropriate in the Mac forums as it is not really related to the iPhone.

How can I create a new ring tone for my iPhone 4?

How can I create a new ring tone for my iPhone 4? I followed the Garage Band process and ended up with the ring tone I want as a AAC audio file. It got stored in my iTunes a a song rather than a ring tone. How do I make it a ring tone vs. a song? I tried dragging it t the Ring Tone category at the bottom of the ITunes list, but it won't alloow me to move it?

There's also an easy to use Applescript over at Doug's Applescripts for iTunes. It automates the whole thing. All you do is set the start and stop time on a file in iTuens and run the script. It will do everything else.

How can I create a text pop up window in my Pages document? I want text to pop up when the reader hovers his/her cursor over a certain word.

How can I create a text pop up window in my Pages document? I want text to pop up when the reader hovers his/her cursor over a certain word in the document. I am teacher. So for example when a student came to word he/she did not know, if he/she hovered the cursor over the word, a defintion or other information would appear. You can do this in Word using bookmarks/hyperlinks but I can't figure this out in Pages. I can link it to another point in my Pages document but I just need the text to pop up - not take the reader to another location. THANK YOU!!!!!!

Have you tried Word for Mac?
You will need to test if links survive export or printing to .pdf

How can i create datasource on apache server for ADF application?

Hi All,
i my use case i have created simple adf application using ADF BC and want to deploy on Apache server 6.x.
So my question is that how can i create Data Source i have goggling and find two different way to do this.
1. write following line of code on apache server conf/Context.xml file.
<Resource name="jdbc/TestDB" auth="Container"

              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1"/>
but when i have used this way i got following exception.
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection
check link-
https://forums.oracle.com/thread/2564233
2. write following line of code apache conf/Server.xml file
<GlobalNamingResources>
    
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"

How can I create a Forms9i Runtime for client distribution

Currently we have an application developed in Forms 5.0.6.8.0 our Database has been upgraded to 9i DB. The application is working fine with this combination but we want to upgrade Forms in order to get Oracle Support. We just get the Developer Suite 9i package and we're trying to test our application with this software.
How can I create the client runtime for Forms 9i?
My application will work with Win 95 and 98?
Thanks.

Oracle9i Forms is web-only. Forms 6i is the last release of Forms to have client/server and character mode.
You can test Forms from the Builder by installing iDS. To deploy Forms using iAS follow the documentation. It's all there in the deployment guide.
iAS and Forms doco can be found on OTN.

How can I create an EntityStore for a Database? Advice on DB strategy?

Hello All,
How can I create an com.sleepycat.persist.EntityStore for a com.sleepycat.db.Database? Advice on DB strategy?
I'm looking to create an application prototype that creates a database dynamically and can delete it programatically. Is openDatabase/removeDatabase what I'd want to use for that?
So far, the Direct Persistence Layer is an amazing piece of technology and has the potential to make my team's application faster than we every though possible, so kudos to the author.
I've built a high-security application using the DPL and a single database for hundreds millions of users. I'd like to attempt to create a database for each user for security and manageability purposes. Our mission statement doesn't allow us to execute queries for sensitive data across more than one user account at a time, so I don't get any benefit from having every user's objects in a single database. I'm investigating if giving each user their own database will speed up insert times and SecondaryIndex queries. It'll certainly be more secure as each database will be encrypted with a unique password.
My design is that I have an app with dozens of com.sleepycat.persist.model.Entity beans which I persist and query on their Primary and secondary indexes. I've been accessing things through an EntityStore as illustrated in the Getting Started Guide. Can I access a database created with openDatabase through an EntityStore and com.sleepycat.persist.PrimaryIndex?
Thanks in Advance,
