Png. Images on ipad

I'm not sure if this is the right place to ask this question. I would like to be able to import png. Images with alpha onto my ipad but have them in my photo library available to be used in my apps, is there any way to do this?
I have searched the Internet and forums here and I see that some people that are usings Mac have somewhat of a work around when using pages but I am on a PC and would like to have them accessible as are all my jpgs.

On a Mac you just import PNG just like you would a jpeg. Transparent PNGs will work in Pages and Keynote. This Apples knowledge base article for Keynote on the iPad tells you to use the PNG formate.
http://support.apple.com/kb/HT4114
I don't think PNGs with a transparent background will work in other apps. You can also import PNGs with GoodReader.

PNG images not displaying in Safari iPad

Hi all,
We have developed a webpage that loads PNG images in a div that can expand / reduce.
The issue i cant seem to solve is why the PNG images do not load on Safari iPad. They just display as blue question marks. However not an issue with PC browsers.
The link is here: http://bit.ly/yBDKl9
Any ideas or suggestions will be welcomed.
King regards,
Matt

Thanks for this. Looks like I'm going to have to reduce the size of my image since I've noticed the same problem on an iPhone 3GS. My original is big but only 2 colour. I don't like ragged edges so best make it 16 shades of grey first so the edges on the smaller image are a bit softer (PaintShop Pro can cope with this). I am certainly not going to degrade it with JPEG zits!
This problem only appears with reduced images (eg. using the HTML style="width:50%;") - if I view source and click on the image link, the full sized image appears, but is far too big for the screen.
Symptomatic of a not-very-good operating system/browser since even M$ got that bit right! BTW - llawjm's website still has the problem he described on my iPhone, but looks fine on a Tesco Hudl (Android) and Firefox on a PC.

PNG images revive deleted images in the form of a thumbnail, potential risk

Saving a PNG image will revive deleted photos. To replicate this, save a PNG image, such as the ones on XKCD's "What If?", and deleted images get revived in the form of a thumbnail overlapping the image.
This has been here since IOS 5, according to http://appleinsider.com/articles/13/11/14/bug-resurrects-deleted-image-thumbnail s-in-ios-7-photos-app-dates-back-to-ios-5
Knowledge of this could be abused. If I get free acess to someone else's Ipad, I can just spam saving PNG images over and over to see their sensitive images saved as a thumbnail overlapping the PNG image's thumbnail.
How do I delete the thumbnails? It seems that when you delete a photo, it saves the thumbnail. This is supported by the PNG images reviving deleted photos in the form of thumbnails.

GPU Mode crash when using 1024x1024px images on iPad Retina with cacheAsBitmapMatrix

So I am building a menu for a mobile app and I have created a sliding menu with tiles, I have done this before, all works great normally.
This time, my tiles were really close to the power of 2 ( 1024x1024px ) so I decided to use that size and resize my tiles to that for performance gains.
So the setup is this:
GPU Mode active, 7 movieclips with 3 frames each, PNG images in those movieclips sized at 1024x1024px. So that's 21 png images.
I need to use the cacheAsBitmapMatrix feature for full smooth performance and when I do, it crashes on the Retina device when loading 1024x1024px images.
On non-retina devices I load the lower resolution assets ( 512x512px) and that works perfectly fine with the cacheAsBitmapMatrix on. On the iPad 1 it runs super smooth.
So I started playing around with the different render modes:
No crashing on CPU mode and no crashing on DIRECT mode, only on GPU setting.
The retina device is NOT out of memory, it does not do anything really heavy. It just loads in these movieclips in a sliding menu, and tweens their alpha, scaleX and scaleY ( which is not part of the issue as it crashes without this too ).
In summary:
1024x1024px images inside of movieclip containers crash an iPad Retina device when using cacheAsBitmapMatrix.
The fix I have found is to just lower the image size a tiny bit: from 1024px to 1016px, it resolves the crash and makes everything work perfect.
So, what do you guys think this could be? I tried with previous versions of AIR (3.7,3.8) and it happens on those versions too. I am using the latest beta of AIR 3.9.

I have not had that happen to me, so I can only speculate, but here are some questions that might help us narrow down the problem.
1. Were the slides created on your ipad, or did you create the presentation on your mac/pc & then import it onto the ipad for presenting?
2. You said When not using Keynote projected images are sharp." Does that mean that the same images used in the presentation display fine on the same projector when you open them in Phoots or another app?
3. Is it only the images on the slide that are compressed, or does it impact text as well?
If you run the presentation on your ipad, not connected to any outside screens, dothe pictures show up normally, or are they compressed then as well?
Like I said, I havent' had this happen to me. My first guess (without knowing any of the details) is that maybe the presentation was created on another device & it was not set to display as 1024 x 768, but at some other aspect ratio, and since that it what the iPad displays at, it is compressing the slides to fit.

PNG images disappear when linked from FM

I am testing the Technical Communication Suite 4. My images are mostly JPGs, and they transfer correctly when I update Robohelp from a linked FrameMaker file. However, I have found that PNG images in the FrameMaker file simply disappear from the update. They don't appear in the Robohelp topic. There is no trace of them in the HTML code view in Robohelp either.
Have others had this experience? Is there a solution?
I am told PNGs are preferable to JPGs in some cases because they load faster on the target device (an iPad, in the case I was told about).

Frankly, I forget because I don't have images in my content. If you don't have a copy of FM8 Fundamentals at hand, try checking the scriptorium.com KB for the info.

hedger,
How do you expect anyone to help when we don't know a darned thing about the file, abut your setup, exact version of Photoshop and your OS, machine specs, etc.?
BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
a screen shot of your settings or of the image could be very helpful too.

How can I add .PNG images to templates without getting a white background?

I'm having problems with a image field when I add a .png image which doesnt have a background it is showing up with a white background. Is it possible to use images in templates so you can overlay them on something else?

Hi, You can do this but only with a PNG with a palette of 256 colors (maybe GIF as well) so doesn't get a lot of use, good enough for image buttons and the like, but might be ok for your image as it does not have that many colors. Otherwise radzmar's suggestion would be the better approach.
This is the link I was tring to find (in your previous thread) that tells how to do it using GIMP (a free image editor), http://smartforms.business.gov.au/DeveloperResources/Pages/HintsandTips.aspx , but the one I have uploaded here comes from photoshop (in photoshop it is called an indexed png).

How to load a PNG image from a location in CF card

Hi,
I am using WTK 2.5.2. I wanted to load a PNG image to Image object. The image is loaded when I have it in the classes folder. But I want to select different image from a different location. If I try to open an Image to createImage(String) from a different location, I get IOException.
Please help me.

I got the answer, I should be using Image.createImage(InputStream) API. It works fine.

Use SVGAnimator to display a SVG with xlink PNG image

I tried the M2GDemo and it works without this image part
SVGAnimator animator =
SVGAnimator.createAnimator( image );
// add our custom event listener
animator.setSVGEventListener(
new CustomEventListener( image, animator ) );
// get the Canvas for this player: requires a cast
Canvas canvas = (Canvas) animator.getTargetComponent();
I modify the requestResource a bit to get Image from root1.
public void requestResource(ScalableImage inImage, String inURI)
     int pos = inURI.indexOf(":");
     if (pos >0){
          inURI = inURI.substring(pos);
     inURI = "file:///root1/"+inURI;
try
Connector.openInputStream(inURI);
catch ( IOException ioe )
ioe.printStackTrace();
<image x='90.0' y='69.46001' width='222.7' height='152.25' xlink:href='myImage.png'/>
Now I stuck with the error below.

I'll check the documentation on BEE and give it a try.
Thanks for your answer.
Thats a starting point for me.

Placed PNG images which are made in 3ds max are not shown correctly in Ilustrator

Hello,
Why placed PNG images (renders) which are made in 3ds max (and then photoshoped) are not shown correctly in Ilustrator. Images appear very noise so you can't see almost a thing. the same pictures (renders) made in Revit appear ok.
Is there a solution to solve this issue?
Thanks.

You would have to provide screenshots of how it looks in PS, including the channels visible. MAX may have embedded extra channels that throw off AI. And of course check whether your PNG is actually 8bit, not 16bit.

Safari on iphone won't render cgi generated png images with query strings

I've got a cgi app functioning as a web service that generates png images and serves them up as part of another app which marshals them up in HTML.
Here's the image stand alone:
http://cybre.net/maps/mapgen.pl.png?WIDTH=1024&HEIGHT=768
and here's how I marshal it:
<IMG CONTENTTYPE='image/png' SRC='http://cybre.net/maps/mapgen.pl.png?WIDTH=1024&HEIGHT=768'>
It seems to work on firefox, epiphany and galeon web browsers for linux, and my windows friends say that internet explorer renders them okay as well.
My only apple hardware is my iphone, and safari pretends that there is no content when it renders the HTML page. Safari on the iphone does not render even using a direct link.
The png is generated by perl mapscript, $img = $map->draw;
print "content-type: image/png\n\n";
$img->write;
close(STDOUT)
On the previous version of the iphone firmware, and before i factored the image generation out into a web service, the iphone was able to render the png image successfully.
Is this safari wierdness where it gets cranky that there is
QUERY_STRING info after the .png? mapgen.pl.png?foo=bar ?
If so, are other browsers just being hyper liberal in what they accept and safari is playing by the rules or is this a bug in safari?
thanks in advance,
-marc

it turns out that safari's handling of png is broken, the problem reproduced on both iphone and mac safaris.
in changing the format to gif, it all works okay.
does apple allow mortals to file bugs against safari?

Files with .png images create huge .pdf's

I use .png images in PowerPoint presentations and these seem to create huge .pdf files. (...don't have this problem using .jpg images) For example, I have a 48 slide presentation that has a small .png image in the "slide master" so it will show up on every page. The PowerPoint file is 2.3MB, however the .pdf of it is 33.3MB, making it WAY too big to email, which was my objective.
Any ideas on how to reduce the size of .pdf's which contain .png images?
...note that I "compressed" the .png images inside of PowerPoint prior to creating the .pdf, but this made no impact.
Thanks,
pm

>I have a 48 slide presentation that has a small .png image in the "slide
>master" so it will show up on every page.
PowerPoint only has to store one instance of the image even thought it is
displayed on multiple slides. But Acrobat can't do the same, the image has
to be stored for every page that it appears on, so that would explain the
larger file size.
Acrobat is supposed to be able to optimize the storage of common background
images (at least that's the message I see when I do a "Save as..."), but I
have yet to see it to work. Maybe it depends on the application the orginal
file is created in and the PDF conversion method used.
Adding the image into a PDF file later as a watermark instead may be a way
to keep the size down (then it really only does store the object once),
though I believe that watermark images will appear in front of everything
else on the page (not sure if that's a problem for you, it depends on
whether any text or objects in the presentation ever appear in front of the
image).
What are the dimensions and resolution of the image in PowerPoint? You may
be able to go as low as 75 dpi and not notice a difference, it depends on
whether the image contains any areas of high contrast or text.

Firefox asks what to do with some PNG images instead of just displaying them

Not sure what is going on here, but some PNG images seem to confuse Firefox, while others are fine. While some PNGs just display when clicked on (eg: when wanting to see a full size image from a thumbnail), others make Firefox ask what I want to do with it. When I select "Firefox 3.6.8" it ends with an error:
/tmp/elementary_gtk_theme_by_DanRabbit-1.png could not be opened, because an unknown error occurred.
Try saving to disk first and then opening the file.
... but when I manually made it open with "/usr/bin/firefox" (I'm in Ubuntu) the image opens fine. I was beginning to think this was now universal for PNGs, but I was opening offending ones from the same site, and going elsewhere showed that some PNGs will be displayed as usual. Does anyone have any idea why this would happen to some PNGs but not all? Here is a link to one of the problem PNGs:
http://s.linux-mag.com/i/articles/7811/elementary_gtk_theme_by_DanRabbit.png
It opens without issue in Opera. Hope someone can make sense of this. Cheers

Displaying the .png image stored in an byte array

Hi,

I have written the code to get the image from the remote server in a java class. The java class returns the byte array of the image and i have to display that in an servlet.
If anybody has the code or any refrence to refer please help me..
Thanks & Regards

I have pasted code for servlet's doGet method which writes image data...
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws
ServletException, IOException
HttpSession session = request.getSession(); //taking httpsession
response.setContentType("image/jpeg");
ServletOutputStream out = response.getOutputStream(); //taking outputstream of response
if (rtn.getErrorCode() == 0)
//this will actually write image file data from where it is being called
//byte array will contain image data, please load your image into below byte array variable
byte[] b = new byte[100];
out.write(b);
out = null; //making null
session = null; //making null
In other servlet, write <img> tag and specify its src attribute to the "name of servlet where u have pasted above code" ..

Can't load PNG images in CS3

I'm unable to load PNG images using Photoshop CS3. Whenever I attempt to do so, I get a message saying, "Could not complete your request because it is not the right kind of document."
Help on this matter would be much appreciated as I am fairly new to using Photoshop.
