How to view an image @ 100% ?

When I do some editing in iPhoto, especially sharpening, I'd like to see it @100%.
There is no indication at what % I'm viewing the image.
Is there any way to know that ?
When clicking "edit" on the bottom, at what size the image opens?
Thanks!

ok, I found an Apple article from 2007 which explains how to do that. I'm posting it here for others:
===================================
iPhoto: Sharpness adjustment may not be apparent when viewing at less than 100 percent
Last Modified on: July 13, 2007
Article: 301425
When you view an image at less than full size, iPhoto smooths it (a technique known as anti-aliasing) to get rid of artifacts that result from scaling down the photo. The relationship between anti-aliasing and sharpening is a trade-off; although anti-aliasing does not modify the actual image file, it does counter the effect of sharpening when viewing the image at less than full size.
Because of this, if you sharpen a photo, close it, then reopen it again at a less than 100-percent view, you may get the impression that your sharpness changes were not saved. In reality they were, but since the image has been re-aliased to fit your screen, the image's true sharpness may not be apparent.
To evaluate whether an image is sharp or needs sharpening, you should view the photo at 100 percent/full size while editing in a separate window. To open the photo in a separate window, you can either Control-click the image and choose "Edit in a separate window" from the shortcut menu, or change your iPhoto preferences:
From the iPhoto menu, choose Preferences.
In the General pane, locate the preference for "Double-click photo."
Set the radio button to "Opens photo in edit window."
Close the preferences window.
Now photos will open in a separate window when you double-click them. Once in the separate window, choose 100% from the Size pop-up menu. If you don't see the Size menu, widen the window until it appears.
Tip: If you are editing the photo from one of the other view options, you can press the 1 key to quickly jump to 100 percent view.
Other applications, such as Adobe Photoshop, handle anti-aliasing differently, so the degree of apparent sharpness can vary from one application to the next when viewing an image at a scaled-down size. You should see consistency when comparing the image at 100 percent across other applications.

How Adobe viewer scales images?

Hi,
I am putting a JPEG file of lesser resolution than the PDF and is scaling it inside PDF. I have a doubt how the viewer scales the image while rendering? Is it just pixel replication or can we specify inside PDF to use some filters for scaling to get better quality? Can someone please help me regarding this doubt?
Thanks,
Sham

I found the answer myself from the PDF standard. Image interpolation is done if the /Interpolate field in the image XObject is set true. I am quoting from the PDF standard below.
"When the resolution of a source image is significantly lower than that of the output device, each source sample covers many device pixels. As a result, images can appear jaggy or blocky. These visual artifacts can be reduced by applying an image interpolation algorithm during rendering. Instead of painting all pixels covered by a source sample with the same color, image interpolation attempts to produce a smooth transition between adjacent sample values. Image interpolation is enabled by setting the Interpolate entry in the image dictionary to true. It is disabled by default because it may increase the time required to render the image."

How to view an Image in ABAP Webdynpro on button action

Hi Experts,
I want to view an image on a button action without creating a new view or window.
I just need to display the image.
Thanks,
R Sahu

Hi Rabi,
Add Context Attribute "SOURCE_IMG" with type String.
Add Image UI "img_id" in layout and bind its source with this context attribute.
on any method where you want to change/show image dynamically, put this code :
here url can be path to image on local or any url-path for web image.
call method wd_context->set_attribute
       EXPORTING
         name = 'SOURCE_IMG'
         value          = url .
I hope this is what you are looking for.
Thank you

How to add ONE image as artwork for an entire album ?..

How do you add a single image as artwork for an entire album (i.e. without having redundant copies for each individual track).
I already know that iTunes has its own artwork system that allows for this, but this is not helpful if the album art is not in their database.
Thanks in advance.

Furthermore, if iTunes has erroneously downloaded an album cover for you that you want to change, you'll have to highlight the group of songs you wish to change and go to 'info'. Click on the 'album artwork' tab and delete the artwork that's there before adding your own, otherwise iTunes keeps both and only the first one will continue to show as the default.
If you want to download the correct album covers (or a different/cleaner/more accurate version) just go to the Images section of Google, type in the album name and copy the image of what you're looking for. No need to save the image, just copy and paste it. iTunes saves it on its own.

How to view the image as cylindrical view in panorama image viewer?

i.e, the image moved at the end position ,the image seems to jump to the start.
instead of this the image should view as cylindrical view. i.e, that the end of the image sticks to the beginning of the image.

}plz help me regarding this concept

I have learnt a technique when I am programming in flash.
Assume you have a photo cat.jpg with 10 units in width and 10 units in height. You can have a view(viewport) 10 units in width and 10 units in height.
The following shows the width of the photo:
012345679
To show an effect of panorama, you can draw 2 photo at any time. I assume the eyesight of a person move from left to right with 1 unit at a time.
The original image is 0123456789.
If the person move eyesight to right by one unit, the image become
1234567890
If the person move eyesight to right by one more unit, the image become
2345678901
You can program the by drawing 2 images at any time.
0123456789(zero width for second image)
123456789(0, 1 unit in width in second image)
23456789(01, 2 unit in width in second image)
To display part of image, try this link to a program to crop image

How to view an image at runtime?

Hi all,
I am developing a web application using JSP,struts, ADF BC with JDeveloper 10.1.3.
I have added
<input type="image" src="../../images/calendr3.gif"/>
in my Databound table on my JSP page.
I can see the image at Design time but no image at runtime.
What should I do to view the image at runtime??
I have tried
<input type="image" src="<%=request.getContextPath()%>/images/calendr3.gif"/>
in this case JDeveloper completely stops functioning. I don't know why? Maybe it's not allowed to have a jsp tag within a databound jsp form???

Hi,
did you add the image to JDeveloper (hit the refresh button) so it gets deployed with the application ?
Also, look at the generated JSP code to see how the image is accessed. I am sure you will find an improperly defined URL

How to view satellite image during navigation with google maps iphone 5

I am a new iPhone convert. I switched from the HTC EVO that used Google Navigation. Google Navigation in Android allows the user to see the image of the map during actual navigation to be the satellite view instead of the standard map view. I downloaded the Google Navigation App to my iPhone 5 but I can't get the map to switch to satellite view. I can only get the satellite view up for the overview map. Once navigation starts, the screen pops back over to the standard map view. How do I view the satellite image during navigation? Please help....

I don't believe that is an option in Google Maps for iOS.
