Splitting a Flattened Image into Layers so I can use the Paint Bucket to change colors
I have what I think is a flattened image that is part of a Website template. (I'm assuming the image is flattened, because when I use the paint bucket to change the color, it colors the whole thing; and when I use the magic wand, the whole image is selected). I need to be able to use the paint bucket to change the colors. What do I have to do to make the image work that way? The image is made to look like you're looking left to right at four file folders. The folder labels are a different color. Is there some way to separate the folders (now in green), the folder labels (now in yellow), and the white background from each other, so I can apply the paint bucket to different layers later? I've worked on this for hours now, and can't seem to find the answer. I'll have to change the colors in the image at least 10 different times, so I was hoping I wouldn't have to resort to using the brush or pencil tools.
Darlene,
Another way is to use the Replace Color Tool. The Hue/Saturation method is probably easier, but I thought I'd mention Replace Color for your information.
http://www.pixentral.com/show.php?picture=18IBCKnJchzoxfLEaw7Bu93j9W5jS
In my example I changed the 3rd label in your picture to red.
1. Roughly select the label using the Lasso tools.
2. Enchance>Adjust Color>Replace Color.
3. Click on the label in the picture; it will appear in the box as white on black background. In general you would move the fuzziness slider until just the portion you wish to change appears white. In this case since the yellow is uniform with sharp border the fuzziness slider had minimal additional effect, but I did move it all the way right to capture the fringe pixels.
4. Play with the 3 Transform sliders to get the desired result.
In this next example I changed the top of the lighthouse from red to green (why I would want to do that, I don't know!).

Note that in this case I didn't have to move the fuzziness all the way right.

Hi,

Also the image I am trying to insert is .ai will it need to be .jpg or .png?
any help would be greatly aprectiated!
Thanks,
BruceThat works the only thing is that when another one is selected it stays visible i have tried this
this.getField("Button1").display = event.target.value=="Off" ? display.hidden : display.visible;
this.getField("Button2").display = event.target.value=="On" ? display.hidden : display.visible;
this.getField("Button3").display = event.target.value=="On" ? display.hidden : display.visible;
this.getField("Button4").display = event.target.value=="On" ? display.hidden : display.visible;
and alternated them between which one needs to work but that didnt work either, any ideas?

Does any one know what i need to change. When i'm dragging an image into pages it ends up with the images info and web address rather than the image itself. What should I do?
Thank you.Try dragging the image to the desktop and then to the Pages document or
Select and copy the image and paste it into the document.
It could be that the webpage is making it impossible to knick the image. I have encountered that a few times. -

My latest pano photo have missing landscape. Some of the photos are merged into one. I can provide the examples. What could cause this problem on a new 5C?
Thanks for the input. I was finally able to find some test conditions that duplicated the problem, and it is either that or some other out-of-spec diffraction distortion. So I sent it off for repair.

Question
My screen opened, and with every click the page (letters/images) got bigger. I can not get it to return to normal image size. I have to use the slide bar to read across the page. What do i do to correct it back to normal size???Hi jholzworth,
It sounds like you might have accidentally hit the zoom button. Try hitting ''CTRL + 0'' to return it to normal size. Just so you are aware, ''CTRL'' and ''+'' will zoom in and ''CTRL'' and ''-'' will zoom out.
Hopefully this helps! -
Load/import images into layers to create animated gif in PE4
I'm trying to make an animated gif using Photoshop Elements 4.0.
I have numerous images (photos) that I need to insert into separate frames of one image.
(photo1, photo2 ..... photo10 - all combined in layers to create the frames of the animated gif)
I can open each photo separately, copy it, go the the animated gif image, create a new layer, and paste the image into the layer to create a frame in the animated gif. This is very time consuming.
Does Elements 4.0 allow for just opening/importing the separate images (photos) into the layers (frames) of the gif direclty? I remember having software that came with Macromedia Dreamweaver 4.0 in 2000 that made this simple and straight forward.We are not the right people to ask. The Touch forum (for tablet) is at
Adobe Photoshop Touch for tablet
There's a long list f video tutorials here, but I can't see anything about animation

I would like to combine 9 images into one so that I can print them on a card. Can I do this in i-photo or do I need an inexpensive app?
No, iPhoto can't do it. If you have Pages it can be done there very easily. Drag all of the photos into a Pages page, resize and arrange as necessary.
Otherwise you'll need a 3rd party image editor that supports layers.
Some Image Editors That Support layers:
Photoshop Elements 11 for Mac - $79
GraphicConverter - $40
Rainbow Painter - $30
Imagerie - $38
Acorn - $50
Pixelmator - $60
Seashore - Free
GIMP for Mac - Free

I can't import my images into Lightroom 4. What's the problem?
When I insert a CF card into my reader, thumbnails of my images appear in the organizer. When I click on "Import", the following message appears: "The following files were not imported because they could not be read." I didn't have this problem with versions 2 or 3 of Lightroom. Is there a solution for this problem?
Take my apologize for the delay doceddy. This issue is 90 percent permissions related. But one thing is confusing in this. If it would be permission issue it should not affect for example the desktop folder. .
Testing:
1 / Create a floder TEST on the desktop.
2/ Use the transfer method which you normally to download the rwas from your cam. Put few raws into the TEST folder.
3/ Run Lightroom and try to import those in TEST.
4/ If it does not work: highlight the test folder - right click - properties - check if there is read only attribute.
5/ If it so - try to put the blue marker from this box away and click apply.
6/ After this close the dialogue (the operation will run some small time). Then do it again if your system allowed you to apply the change. So second time should be the attribut away. If it is start Lightroom and try to import again from TEST.
7/ Give me some feedback then please - I will suggest you some other steps if it does not work.
Good Luck

Getting Canon 4770 to scan multipages into a PDF file while using the document feeder
Hi All
I'm new to this forum. So if I break any rules with my questions below, kindly forgive me.
But my questions are about my Canon MF4770 printer.
1. Why can't I used the document feeder to scan multiple pages into one PDF file?
2. Why do I have to constantly select the remote scanner option when the printer is connected to my computer?
Any help I can get will be very appreciated.
StarleneHi Starlene and welcome to the Canon forum,
The ability to scan multi-page documents can depend on your operating system and version, and if the scanning software being used supports the feature. However, the MF Toolbox application that accompanies your laser product offers this option when scanning via a USB connection to your computer.
For example, if you are using Windows, below are the steps that would be performed:
1. Place documents.
Note: Up to 35 documents can be loaded in the feeder. Be sure to fan the stack, place it face up, and align the document guides to the width of document.
2. Press [SCAN].
3. Press [^] or [v] to highlight <Remote Scanner>, and then press [OK].
The machine is now waiting to be scanned.
4. Double-click the [Canon MF Toolbox 4.9] icon on the desktop.
The MF Toolbox starts.
5. Click [PDF].
Select [PDF (Multiple Pages)] in [Save as Type].
7. Specify the required settings as needed and click [PDF Settings].
The [PDF Settings] dialog box appears.
8. Specify the required settings as needed and click [OK]:
[Create Searchable PDF] Converts the characters in the document to text data and makes the PDF document searchable with keywords.
[Text Language] Select the language of the text to be scanned. The characters may be recognized more accurately if you select [English] from the drop-down list and set [Image Quality] to [300 dpi] or higher in [Scanner Settings].
[PDF Compression] Select [High] for color images such as photos or illustrations to reduce file sizes.
9. Click [Start].
Note:
A folder with the scanning date will be created in the [MY PICTURES] folder in the [MY DOCUMENTS] folder, and your document will be saved in this folder. If there is no [MY PICTURES] folder, the folder with the scanning date will be created in the [MY DOCUMENTS] folder and your document saved in this folder.
For text documents or black-and-white documents, it is recommended you select either [BLACK and WHITE] or [GRAYSCALE] in [SCAN MODE].
If making a Multiple PDF with color documents ([IMAGE QUALITY] set to [300 dpi]), it is recommended that the PDF have fewer than 20 pages.
The MF toolbox can be loaded from your software CD or downloaded here from the "Drivers & Software" tab on the Canon USA website.
I can understand some confusion on having to select "Remote Scanner" when you have a direct computer connection to your product. The reason for this is that first, the "Remote Scanner" mode refers to seeing your computer as a stand alone, or remote, device; however, the "Computer" scanning mode option allows you to select which computer will be performing a scan when doing so over a network (Max: up to 10 computers).
Another reason for having to select the scan mode is that the selection is not programmed but selected based on the type of scan you will be performing at the time.
