Zoom in/out into images

Hi mates ,
wanted to know if there is a method for zooming in/out to images or ill just have to implement it myself ?

lshaibin,
Use Graphics2D scale method in the paint method of your class that extends JPanel class.
example:
public void paint(Graphics g)
Graphics2D g2 = (Graphics2D)g;
// If you want some quality
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION,RenderingHints.VALUE_INTERPOLATION_BICUBIC);
g2.scale(zoom,zoom);
g2.drawImage(image,0,0,null);
g2.dispose();
}

What script for Zoom in/ out of image?

1. I plan to import quite bigger bitmap image and save as a
Graphic Symbol
2. Make some Botton Symbols for +(Zoom in, -(Zoom out) and
Reset.
3. If I click +(Zoom in) button, image (reduced sized image
in smaller window) got magnified.
----> What scripts do I need for this design? I'm working
on Flash8.
Thanks much in advance!!
*** I got this idea from the site of
http://www.metmuseum.org/explore/cezannes_apples/look.html
And click "Let's Look Closely"...

First of all, dont put your image as a graphic symbol ... use
movieClip instead.
Lets say you transform it into a movieClip and give it the
instance "image" and that your zoom button is called zoomBtn and
the un-zoom button is called unZoomBtn:
//--> start the loop for zooming in on "press" event
zoomBtn.onPress = function(){
this.onEnterFrame = zoomIn;
//--> start the loop for zooming out on "press" event
unZoomBtn.onPress = function(){
this.onEnterFrame = zoomOut;
//--> stop the loop for zooming in or out on "release"
event of both buttons
zoomBtn.onRelease = unZoomBtn.onRelease = function(){
delete this.onEnterFrame;
//--> line of code executed in loop for the zoom in
function zoomIn(){
image._xscale = image._yscale += 5;
//--> line of code executed in loop for zoom out
function zoomOut(){
image._xscale = image._yscale -= 5;
}

PS CS5.1 - Changes/additions to doc don't appear until I zoom in/out of image

Good evening,
Over the past few weeks I've encountered a problem with Photoshop CS 5.1. Anytime I make an addition or alteration to an image (not a photo, but a digital composition) whatever I've done does not appear until I zoom in or out of the image. I have also tried waiting a few seconds to see if the program just lagged but it still doesn't appear until I zoom in or out. An example would be if I add text to a document, while I'm typing the cursor will move as I type but the text doesn't appear until I zoom. This is with solid text and of a color differing from the background.
I tried increasing the memory available to the program (I have given it about 6gb), still occurs. I uninstalled and reinstalled the program, problem persists.
I'm running Windows 7 64bit, Intel i7 1.6ghz, 8 gb of memory
Any possible solutions would be very helpful. I've resorted to using CS2 and I would love to move back to CS5.
Thanks

Hi there! Because the forum you originally posted in is for beginners trying to learn the basics of Photoshop, I moved your question to the Photoshop General Discussion forum, where you'll get more specialized help.

Images I move from one folder into another are disappearing, at first it was occurring immediately if I did not copy and paste the images. Today however I found out that images I had been using for days just up and vanished from their new location.

Images I move from one folder into another are disappearing, at first it was occurring immediately and only if I did not copy and paste the images. Today however I found out that images I had been using for days just up and vanished from their new location. A few of these images had copies in another folder that remained and the ones I couldn't find may or may not have ever had copies. I had backed up my system with time machine recently as well, so I went into the backup to retreive the lost images. When I searched and found the backup copies I got the error "the file alias cannot be opened because the original cannot be located". The crazy thing is that the images that remained on my computer did not give me the same error and opened like they should.
In short images that I am creating, saving, and using are disapearing so epically that even time machine versions are affected when retrieval is attempted. Any suggestions as to what I could be doing wrong without realizing it? Or perhaps other people have had similar bugs that are software related and have a solution?

Hi Kevin,
I understand what you tried to do but it doesn't work that way. Swapping drive names will just mess things up.
You should be able to reconnect the files though: in the Locate Referenced Files dialog make sure you click the Show Reconnect Options button — this will give you access to all the connected drives. Locate one of the files and hit Reconnect All. Should do the trick.

Zooming into image problems

Hi everybody,
I'm trying to learn how to zoom images, and I've been able to put together a test program; based on the posts I've seen on this forum (I didn't see anything about zooming in the Java tutorial), I thought it should be working, but it doesn't.
My GUI consists of a JLabel with an icon on it, and a button panel beneath with zoom percentages. When I click on one of the zoom percentage buttons, the image is supposed to zoom in or out to that percent magnification, based on its original size (when the GUI is first created). When I click on the buttons in my test GUI, though, nothing happens to the image.
EDIT: Oh, and I forgot to ask -- is zooming an established image like this the same as zooming a panel on which something has been painted? That's my eventual goal, but I thought it might be easier to learn with an established image first.
Would anyone mind looking at my code, please, and giving me a hand?
Thanks,

Flash Component: Image - crop, resize, rotate zoom in/out

Hi, We've got a photo contest and we need an image
manipulation tool that will allow users to import image, crop,
move, resize, roate and zoom in/out to align their photo within a
frame for example. Any one know of a component like this? I would
appreciate and advice or links to other sites.
Thanks in advance.

Resize the actual image file? If so, PSA SE can't really do that.
Just look at an image at different magnifications? Select image, F11 for full screen, then use CTRL/+ and CTRL/- to adjust.

Best way to insert a table into image with high resolution for web?

I've tried inserting a table from Excel into Photoshop and making a jpeg and gif out of it, but when I upload it to the web the resolution is terrible.
Any ideas on how I can make get a table into an image? It's a bit too complex to create with HTML.

Well, you are leaving out a lot of info.
a: how are you saving it in Photoshop? What file type/compression amount, etc.
b: how are you uplaoding it - where are you uploading it - are you uploading JUST the image, or are you uploading the image within an .html document?
One thought, if you are JUST uploading it as an image, then trying to view it in a browser, if the image is larger than the viewport of the browser, some browsers will automatically rezie the image to fit visually into the viewport. More than likely, this resizing could be causing image distortion. Imagine it like when you zoom in/out in Photoshop - (unless you are using the accelerated graphic gui option in PS preferences), any zoom level outside of 25%, 50%, or 100% will cause visual distortion.
Give a link to where you have uploaded the image (or whatever you are talking about). Like I said, there are other things to consider as to why this is happening.

1:1 Zoom difference between similar images

Hi   I have just upgraded to Lightroom 5 and am still figuring it out as I go.
I have recently been facing this baffling zoom problem.   For some reason when I zoom in 100% into an image it works just as it should. But when I zoom in to the next image which is exactly the subject shot in burst mode ...I actualy get a less than 100% zoom although on Navigator it says it is a 1:1 zoom. All my pictures have a combination of this contrasting zoom and I just can't figure out why? There seems to be no pattern!!!
Thanks
Preeti

Yes I do.
A friend suggested the following...to connect your hard drive, select all the images, discard the 1:1 preview and then discard the smart previews. Then Build the Smart Previews first followed by the 1:1 previews.
I did that...
I started out small, with a folder that had only 15 photos but still had this pesky problem. I did as was suggested and it worked perfectly for this folder.
Then I thought I should try it out on a bigger folder with 318 photos before going all out. I did exactly as was suggested again. Everything was fine till it came time to building 1:1 previews. Instead of building 318 previews. It said it was building only 49!!!! And after that process as you can imagine the problem still persisted. So I tried again. This time I got 79 1:1 previews. And the last time I got 88. Thing is each time after the task is completed it says that 318 1:1 previews exist or were created.
So I looked out for some of the problem photos and tried the discard preview - smart and 1:1 on them. I chose 9 such photos but only 1 or 2 1:1 previews were created. And then like magic it worked. In a second group of photos it didn't work.
I am now utterly and thoroughly confused.

Zoom- after initial zoom I want the image to return to original size

After trying many different ways to zoom on one slide I have
broken each zoom (of a selected image) out into 8 slides. I am
wondering though... if I select the zoom to only last a few
seconds, why does it continue to be 'zoomed' even after that time
alloted has past?

Hi bfair76 and welcome to our community
Notice that the Zoom feature is typically configured for
displaying the zoomed area for the slide duration. But you can
easily change this. For example, I had a slide timed for 3 seconds.
I inserted a zoom area and it zoomed for 1.5 seconds and stayed on
the slide until the slide time ended at 3 seconds. I then increased
the slide time to 5 seconds and the zoom followed suit. If you
double-click the zoom object and click the Options tab, you may
easily change the "Display for" area from "rest of slide" to
"specific time", then configure the duration as desired.
Hopefully this was helpful to you... Rick

Alt & scroll wheel not working on Photoshop CC to zoom in / out

Hey! So i'm using the latest version of Photoshop CC, and i'm also running the Technical Preview of Windows 10. So In Photshop, usually when you hold the alt key and scroll with the scroll wheel on your mouse, it will zoom in / out of the image on Photoshop. Well i'm having some problems with that, it isn't working at all. In preferences I have it set to zoom with scroll wheel. Anyone know why it isn't working? Could it be something with the Windows 10 Preview?

Please report Windows 10 issues to Microsoft, so they can get the information they need to fix the OS bugs before shipping the final version.
