How do I save a PNG file with an alpha channel in Photoshop CS5?

I have a PNG file created in Photoshop and I need to save it with an alpha channel for web purposes. I tried 'Save for Web & Devices' and selecting the Transparent box. Then, after saving, when I select 'get info' for the file it says there is no alpha channel. I'm stumped I can't seem to create an alpha channel from within Photoshop while I'm editing. Help!

If you save as a 24bit png with transparent checked photoshop will save the png with transparent background (ie alpha transparency). The png will appear transparent in a web browser.

How can I save a XML file with JAXP1.1?

Dear All.
I write a program to create XML file with DOM model, but I can't know how to save it? My environment is JAXP1.1 and JDK1.3.1,I has been required not use other XML parser toolkits,only JAXP1.1.
How can I do? thank you.
Many person give me a idea the com.sun.xml.tree.XmlDocument, but I can't find the class in API document or JAXP1.1's packages. why?
what is it? How can i use it?
thank you very much.

The way to save an XML Document is using a Transformer.
To have access to a transformer use the packages :
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
Then for saving your Document Object (named dXml) get a Transformer Object with the TransformerFactory Object :
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer();
Now you have got your Transformer Object, to save your Document Object use the method :
Document dXml = getMyDocument(); // this is your Document Object.
OutputStream osSave = getMySaveStream(); // this the OutputStream you need to save your Document.
try
t.transform(new DomSource(dXml), new StreamResult(new OutputStreamWriter(osSave)));
finally
osSave.close();
And your Document was now saved.

I have a Macbook Air (july 2012) with OS X 10.8.3 installed. I have dvds with .vob files and have Quicktime Version 10.2 (603.12). I can't play the DVDs. There are some features of QT that I like, e.g. precise frame selection and save as .png file-help. Am I missing some Apple software? I thought QT for Mountain Lion could convert the .vob files - is there some setting that I have missed?
Any suggestions that preserves a simple workflow much appreciated.

With what program are you working and with what version of the program and on what computer operating system?
I suspect that you are working with some version of Photoshop Elements. If that is correct, then be advised that some how
your thread got posted in the Adobe Premiere Elements Forum (video editing) instead of the Adobe Photoshop Elements Forum (photo editing).
If Photoshop Elements question, then please re-post your thread in the Adobe Photoshop Elements Forum or wait for a moderator

Thought....if are creating an image on a transparent background in Photoshop Elements Windows for a Premiere Elements Windows project, then you Save As png or psd.

The same way you save ANY email attachment... which is going to depend on the email program you use... so check with support for your email program (or the help file to learn how to save an attachment)
When you OPEN a PDF attachment, what program are you using... Acrobat or Reader... both have options to save files

How do I save all mp3 files as an attachable audio file in text messaging on a G'z One Commando? Some mp3 save as these types of files but I don't how or what I do differently.

In summary, it sounds to me as though the Mac concept of "hidden extension per file" isn't embraced at all by Photoshop.
So assuming the extension is always visible, what is the easiest way do each of the following (ignoring issues with integration with other apps):
1. Save a JPEG as: abc.jpg
2. Save a JPEG as: abc
3. Save a JPEG as: abc.
4. Save a JPEG as: abc.xxx
Since it seems to me we still haven't nailed down whether there's a disparity between how this works on Photoshop for Mac vs. PC, I'll answer the above questions for PC:
1. File - Save As, choose Format: JPEG, type (replace filename with): abc
2. No difference than 3 on a PC.
3. File - Save As, choose Format: JPEG, type: abc.
4. File - Save As, choose Format: JPEG, type: abc.xxx
How is it different from the above on a Mac?
Is there something more complex, such as the sequence of operations, or another system setting, that I didn't cover here? I normally always keep Explorer set so that file extensions are visible (it's global on a PC).

How do I open a png file?

Cheers All,
I am not seeing how to open a png file with the new Creative Cloud Pshop.
I am fearing that it has been disabled by Apple or some such nonsense.
My last version of shop had a right click 'open with', which I am not getting now with CC.
many thanks, Dave

Thanks Mylenium, both for the reminder to inform the Forum of device and OS, and, for the answer to my question!
I have had long standing issues with setting the 'open with' default , both over device and over the years; thus I had forgotten the option altogether.
Having wiped this old computer clean and started fresh, the new default I just set to use CC to open png files is functioning as it should!
Cheers and thanks again!

How do I save and find files on the ipad?

How do I save and find files on the iPad?

Files/documents need to be stored/associated within an app on the iPad, unlike 'normal' computers there is no file system which allows you to save files with no means of being able to read/use them. So if you want to store a file on the iPad you first need an app on the iPad that supports that file type.
How you then get the file onto the iPad and into the app will depend on what the app is and what transfer method(s) it supports. e.g. some apps use the file sharing section at the bottom of the device's apps tab when connected to your computer's iTunes, some apps support the transfer of files via your wifi network, the iBooks app uses the Books section of your iTunes (and the device's Books tab) to sync content, and other transfer methods include email attachments, Dropbox etc. The file is then found by going into your chosen app and opening/using the file.

How do I save a excel file to be compatible...

How do I save a excel file from a pc to be compatible with my Mac?

Hi juicebars,
iWork is a productivity suite for Macs running OS or iThings running iOS. With a MacBook Pro you will need the OS version.
iWork consists of:
Pages, a word processor and page layout app (page layout mimics a drawing app). Pages can import Microsoft Word documents and you can edit and save them. Also Export as MS Word, PDF, plain text, RTF or ePub.
Numbers, a spreadsheet app that mimics a database. Numbers can import Microsoft Excel or CSV documents and you can edit and save them. Also Export as MS Excel, CSV or PDF.
Keynote, a presentation app. Keynote can open Microsoft Powerpoint. I don't use Keynote, so I can say no more.
You can buy the iWork suite from the App Store, or buy Pages, Numbers and Keynote separately.
There are some minor conversion glitches when converting between MS Office and iWork. If you are continually converting, it is best to buy Office or LibreOffice for Mac.
iWork does not take kindly to huge documents.
However, I find that Numbers and Pages for Mac OS to have a sweetly intuitive way of doing what I want.
Regards,
Ian.

Automator or Applescript using png files with alpha channel

I have hundred of png files with alpha channel.
I want to suppress alpha channel.
How can i do it using Automator or Applescript ?
Thank you very much.

You can use the free command line image processing tool ImageMagick in your Applescripts or Automator workflows, as well as from a Terminal shell.
You can download ImageMagick from http://www.imagemagick.org, but Cactuslab has simplified installation by putting together an installer package. It’s available at http://cactuslab.com/imagemagick/. Download the package and double-click on it. Follow the instructions to install. It will install ImageMagick into /opt/ImageMagick and add it to your $PATH by creating a file in /etc/paths.d/. Restart your computer for the changes to take effect.
The two ImageMagick commands we’re concerned with are “convert” and “mogrify”. Convert is more efficient for multiple and piped operations on the same image file, and mogrify is more efficient for batch processing. Generally speaking, convert will output a file separate from the input file. Unless a path is specified, mogrify will overwrite the input file with the output file. An important distinction.
You can perform various operations on the alpha channel using arguments after either the convert or mogrify command. Two of the available arguments are:
-alpha off - Disables the image's transparency channel. Does not delete or change the existing data, just turns off the use of that data.
-alpha remove - Composite the image over the background color.
Also of use are the -flatten and -background options:
-flatten - overlay all the image layers into a final image and may be used to underlay an opaque color to remove transparency from an image.
-background - sets the background color.
Start off using the convert command with a single image to see the effect and adjust to your liking. Once you’ve achieved the desired outcome, then use the mogrify command to batch process the chosen images.
Before getting into how to use Automator or Applescript in your workflow, use Terminal and the command line to see the effect on a single image. Copy one image to your ~/Desktop. In Terminal change the directory to ~/Desktop by typing the following command and pressing the Enter key:
cd ~/Desktop
Then choose the option you are looking for, -alpha remove for instance, type the following command and press the Enter key:
convert input-photo.png -alpha remove output-photo.png
You can check the alpha channel (transparency) and background in the Preview app, go View > Show Image Background from the menu bar.
Once you’re ready to batch proces, place all the photos you want to convert with the same command into one folder. Copy the folder to your ~/Desktop. Let’s assume you’ve labeled the folder “InPhotos”. It’s prudent to manipulate copies in case something goes amiss. In that event you can copy the folder with the originals again and start over. Create a new empty folder on your ~/Desktop and call it “OutPhotos”. Let’s also assume your home directory is called “Me”. The following command will process the photos from the InPhotos folder and put them in the OutPhotos folder:
mogrify -alpha remove -path /Users/me/Desktop/OutPhotos/ /Users/me/Desktop/InPhotos/*png
According to Apple Technical Note TN2065:
"when you use just a command name instead of a complete path, the shell uses a list of directories (known as your PATH) to try and find the complete path to the command. For security and portability reasons, do shell script ignores the configuration files that an interactive shell would read"
So, you need to use the full path to to ImageMagick commands, unlike in the shell where you can just use the command name.
To batch process using Automator, use the “Run Shell Script” action (note: retain the single space at the beginning of the last line):
/opt/ImageMagick/bin/mogrify \
-alpha remove \
-path /Users/Me/Desktop/OutPhotos/ \
/Users/Me/Desktop/InPhotos/*png
To batch process using Script Editor (Applescript), use the “do shell script” command:
do shell script "/opt/ImageMagick/bin/mogrify -alpha remove -path /Users/pd/Desktop/OutPhotos/ /Users/pd/Desktop/InPhotos/*png"

-background black -flatten:
-background blue -flatten:
-channel alpha -evaluate Divide 2:
-channel alpha -evaluate Divide 2 -background black -flatten:

jpg and pdf formats don't support transparency. You need to use a format such as tif, png or psd that does.
