Resize images is RSS widget.

Hello, I have the below code for an embeddable rss widget. Is it possible to automatically resize the images in the feed so that they're the width of the widget?
I'm reluctant to use the bult in widget in iWeb as it doesn't show as i want it to in IE but the image manipulation on the built in one is perfect.
Any ideas?

RSS Widget: Feed is not live online but works when building screen

I use the RSS widget in iWeb, the feed "loads" in the program I publish the page then do my FTP transferring the folder, html page and feed.xml with my host but the page (http://www.savingtherepublic.com/STRBlog.html) the feed is embedded in is blank
I took a screen shot to show it is working but I cannot upload the image to this board so "you" can see it is in fact done right, otherwise I would get errors that the feed in inaccessible etc.
So what am I missing? I followed a vid and the "learn more" instructions to a 'T'
this is the url input in the subscription box for the widget feed://savingtherepublic.wordpress.com/rss.xml

Rss widget won't update

I recently updated my blog but the rss widget won't update with the new entry, I've waited a full day. The rss feed address is: http://www.berrylibrary.com/Blog/rss.xml
Apple Mail, Google Reader, etc. all get the update but the iWeb RSS Widget refuses. I also took the widget out and put it back with no success.

Here is my trick to get my rss feed fixed:
Make a change in the Inspector that only affects the blog (but all entries), like disabling comments and right away enabling them again in the rss window of the Inspector (I don't know for sure but this could erase your existing comments); that will return the images in the right places or put them back if they disappeared altogether. This will also clean up the rss feed.
Disabling comments crashes iWeb, so it is important to enable it immediately after having disabled it, so you click in fact twice in the check box, off and on again.
But you will have to do this each time you add a post to your blog, or to any of your blogs, because it seems a change in one blog or site may have a damaging effect on an other blog.

Anyone know why RSS widget gets stuck at "downloading RSS feed"

I have added a RSS widget to a page in iWeb and it just sits there at "downloading RSS feed" - when I publish the page there is some RSS feed data there but only a small amount and it's quite old.
The feed I'm using works perfectly in a safari browser but not via the widget - I'm running iLfe11 iWeb 3.0.3 (501) and OS X 10.6.7
Any help please?

There is a whole lot of extraneous material in the feed: I'm not familiar with SquareSpace so I don't know the procedure, but I assume you've started as a weblog page with a lot of text and images and the feed has been taken from that. It's probably harmless as iTunes should simply ignore it, though it does make the feed very difficult to read.
The matter of the media file is more difficult. I'm afraid the simple answer is something you don't want to hear - give up on SquareSpace and go somewhere else. If you host your files on a normal webspace server - with only the caveat that it must support 'byte-range requests' which is mandatory, so you need to ask about this before committing yourself - you shouldn't have any trouble. Some of these weblog creation services can cause problems, though I don't know of any specific issue with SquareSpace.

Which approach to use for resizing image

There are two ways of resizing images as I know:
1. image.getScaledInstance(width,height,hint);
Using hint like Image.SCALE_AREA_AVERAGING gives somehwat satisfactory resizing.
2. static BufferedImage resize(GraphicsConfiguration gc, BufferedImage source, int w, int h, Object hintValue) {
BufferedImage result = gc.createCompatibleImage(w, h, source.getTransparency());
Graphics2D g2 = result.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, hintValue);
double sx = (double) w / source.getWidth(), sy = (double) h / source.getHeight();
g2.drawRenderedImage(source, AffineTransform.getScaleInstance(sx, sy));
g2.dispose();
return result;
where the hint passed is RenderingHints.VALUE_INTERPOLATION_BILINEAR ;
Now which of the two method method should I use-using image.getScaledInstance() or using AffineTranform ? opr is there any other way which is faster but provides good result?
i am creating an image editor, so the GUI dialog will have oprtion to choose the algorithm. I want the method which provides better result yet faster.

Need help on quality of resized image!!

I am required to resize images to max 1240pixel (longest dimension) as a submission of work, though when work is viewed it will be at 30"x40". Can not figure out a way to do this where images don't become quite pixelated when viewed at larger size. Appreciate any suggestions.

Is there some software to verify if my graphics card is shotty?
Techtool Pro has some testing, the AHT tests VRAM, but game benchmarks and stressing will tell you the most.
Is re-seating the graphics card or memory worth trying?
Absolutely. Just don't reinstall the graphics card until you clean it thoroughly.
Cleaning the dust out of my machine?
YES. A dust filled graphics card heatsink will cause the GPU to cook, and cause problems thet you describe.
If I need a new graphics card, what are my options? Do I have to purchase it via Apple store? I would like to stick with an Nvidia card so am I stuck buying the same card I currently have or can I upgrade?
You don't have to buy from Apple, but using with OS X limits your choices to Mac compatible or flashable PC versions.
There is an awful lot of user input into this topic here:

I need some help resizing my images on PS6. I am using a mac and have been trying to resize with same resolution and constaining proportions but for some reaseon the smaller resized image appears pizelated.

I need some help resizing my images on PS6. I am using a mac and have been trying to resize with same resolution and constaining proportions but for some reaseon the smaller resized image appears pizelated. Heres an image of before and after. The first image I use is a JPG 72dpi 1500px x1500px and I want to downsize it to 600x600px same res, but it keeps pixelating, this has never happened before. Any suggestions, thoughts?
thanks!

I wouldn't say pixelated; more like blurry.
Like ConnectedCreative said, what steps are you using? Are you using "bicubic sharper" when resizing down?

Upload and Resize Image not inserting filename in database

I have a form that I created using the insert record form wizard. One of the fields is a file field and my form enctype is set to multipart/form-data. I then used the upload and resize image behavior and set the parameters. When testing the form the file uploads to the correct directory but no entry is made into the database for that particular field. The other fields are entered into the database just fine. If it helps, here is the code generated before the tag:
 
 <?php require_once('../../Connections/test.php'); ?>
 <?php // Load the common classes require_once('../../includes/common/KT_common.php'); // Load the tNG classes require_once('../../includes/tng/tNG.inc.php'); // Make a transaction dispatcher instance $tNGs = new tNG_dispatcher("../../"); // Make unified connection variable $conn_test = new KT_connection($test, $database_test); // Start trigger $formValidation = new tNG_FormValidation(); $tNGs->prepareValidation($formValidation); // End trigger //start Trigger_ImageUpload trigger //remove this line if you want to edit the code by hand function Trigger_ImageUpload(&$tNG) { $uploadObj = new tNG_ImageUpload($tNG); $uploadObj->setFormFieldName("picture"); $uploadObj->setDbFieldName("picture"); $uploadObj->setFolder("../images/"); $uploadObj->setResize("true", 120, 0); $uploadObj->setMaxSize(1500); $uploadObj->setAllowedExtensions("gif, jpg, jpe, jpeg, png, bmp"); $uploadObj->setRename("auto"); return $uploadObj->Execute(); } //end Trigger_ImageUpload trigger // Make an insert transaction instance $ins_team = new tNG_insert($conn_test); $tNGs->addTransaction($ins_team); // Register triggers $ins_team->registerTrigger("STARTER", "Trigger_Default_Starter", 1, "POST", "KT_Insert1"); $ins_team->registerTrigger("BEFORE", "Trigger_Default_FormValidation", 10, $formValidation); $ins_team->registerTrigger("END", "Trigger_Default_Redirect", 99, "../team.php"); $ins_team->registerTrigger("AFTER", "Trigger_ImageUpload", 97); // Add columns $ins_team->setTable("team"); $ins_team->addColumn("id", "NUMERIC_TYPE", "POST", "id"); $ins_team->addColumn("sort", "NUMERIC_TYPE", "POST", "sort"); $ins_team->addColumn("name", "STRING_TYPE", "POST", "name"); $ins_team->addColumn("title", "STRING_TYPE", "POST", "title"); $ins_team->addColumn("description", "STRING_TYPE", "POST", "description"); $ins_team->addColumn("picture", "FILE_TYPE", "FILES", "picture"); $ins_team->setPrimaryKey("id", "NUMERIC_TYPE"); // Execute all the registered transactions $tNGs->executeTransactions(); // Get the transaction recordset $rsteam = $tNGs->getRecordset("team"); $row_rsteam = mysql_fetch_assoc($rsteam); $totalRows_rsteam = mysql_num_rows($rsteam); ?>

If the reason is about memory, warning message should be happened when upload the image, because "show thumbnail" means resize at second time, how come you failed to resize the picture that system let it upload succeed at the first time by the same resize process?
upload procedure
a.jpg: 2722x1814, 1.2mb
upload condition: fixed width 330px, 1.5mb
"upload and resize" a.jpg -> file upload -> "resize engine" -> passed (but not work and no warning message)
"show thumbnail" a.jpg -> "resize engine" -> failed (not enough memory)
it doesn't make sense.
and you miss an important key point, I upload the same picture myself, and resize work, so I said it happened at random, and that's why I am so worried.

Resize image in pdf file

I need to resize image in pdf ,
I get this [http://www.java2s.com/Tutorial/Java/0419__PDF/Positionandresizeanimage.htm]
I try to put the code in my servlet

Thank You

PdfContentByte cb = writer.getDirectContent();There is no such method in the JDK or the Servlet API.
Ask whoever provides it.

Resizing images published through flickr, but I don't want it to.

I set up a flickr connection with LR3, very cool. However it resized the image to 1024x768, though I have nothing set under 'resize'. Why is it doing that? Do I have to set it to resize everything to 9000 pix and not enlarge for it to keep the original size?

Setting the resolution to 9000 x 9000 wont make any difference. Or at least it did not for me.
It could be a limitation of Flickr (no Pro account). Perhaps it is different with a Pro account.size file is being uploaded if you dont resize on output but you wont see it if you dont have a Pro account.
In fact, from the Flickr site: Only smaller (resized) images accessible (though the originals are saved in case you upgrade later)
This would suggest that your original size file is being uploaded if you dont resize on output but you wont see it if you dont have a Pro account.

Problem with getting resized image's bytes

I've got a problem with getting correct bytes of a newly resized image. The flow is that I retrive an image from the filesystem. Due to the fact that it is large I resize it to a 50x50px thumbnail. I can display this thumbnail in #benchmark1 (see code below). Unfortunately something's wrong with my imageToBytes funtion which returns reasonably small size of image but is totally useless - I can't make an image of it anymore so at #benchmark2 the application either crashes or keeps freezing. I saved this byte array on my disk and tried to preview under Windows how does it look but I got a message "Preview unavailabe". I did some digging in the Internet and I supposed that it's because I don't use any jpg or png encoders to save the file. Actually I think that it's not the case, as the bytes returned from method imageToBytes look weird - I cannot even make a new image of them and display it without any saving in memory.
 byte[] bytes = FileHandler.readFile (
 FileHandler.PHOTOS_PATH, fileName);
 Image img2 = Image.createImage (bytes, 0, bytes.length);
 img2 = ImageHandler.getInstance ().resize (img2);
 //#benchmark1
 bytes = ImageUtils.imageToBytes (img2);
 img2 = Image.createImage (bytes, 0, bytes.length);
 //#benchmark2my imageToBytes function is as follows:
 public static byte[] imageToBytes (Image img)
 int[] imgRgbData = new int[img.getWidth () * img.getHeight ()];
 byte[] imageData = null;
 try
 img.getRGB (imgRgbData, 0, img.getWidth (), 0, 0, img.getWidth (),
 img.getHeight ());
 catch (Exception e)
 ByteArrayOutputStream baos = new ByteArrayOutputStream ();
 DataOutputStream dos = new DataOutputStream (baos);
 try
 for (int i = 0; i < imgRgbData.length; i++)
 dos.writeInt (imgRgbData);
 imageData = baos.toByteArray ();
 baos.close ();
 dos.close ();
 catch (Exception e)
 return imageData;
I've run totally out of any idea what's wrong, please help!

Hey Crawlie,
Please note that simply writing int values into ByteArrayOutputStream will not suffice. Please have a look at the following conversion from int pixel value into byte[4]:
public static final byte[] intToByteArray(int value) {
 return new byte[] {
 (byte)(value >>> 24),
 (byte)(value >>> 16),
 (byte)(value >>> 8),
 (byte)value
}Good Luck!

Resizing Image and Not Keep Aspect Ratio

Is there a free program to resize images and not keep the original aspect ratio?
I need to resize loads of images to 100x100 pixels and have tried Image well and IResize yet they do not seem to have an option to not keep the original aspect ratio.
Thank you

Hi, Downsize does not seem all that great according to reviews. Why not see if you can buy PS E' 3 mac -- maybe ebay/amazon (if I remember I only paid about $70 for PS E3) As PS E4 just came out I'm sure someone has PS E3 for sale. You will then have no problems completing your image resizing.
2 other questions for you..are you using the Mac side of your intel or Windows?
if your using the Windows side I can let you have PS 6 (PC) ..freegratus.

Resizing images

I am using Photoshop CS (older version).
I am having a problem with resizing images. Prior to sending this, everything was working okay and now nothing will resize. my file path was file menu > automate > batch > and then I would choose my source and destination for the resized images. In the end, all the newly resized images would stay the same size as before. Can someone please help me with this???

Neil,
Have you selected the "resizing" action in the Batch dialog?

RSS widget in iWeb. Can someone help?

Hi There,
I am having an issue with iWeb and the RSS widget.
Having created a website for my company, i wanted to put our twitter feed on the home page using RSS. Now obviously twitter have stopped making it easy to use the RSS service, however i managed to track down the link that the RSS is on.
This link was http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=(inserttwitterna me). So i changed the last part to our twitter name making the link look like this:
http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=bluecrewuk
This link worked on the iWeb page for about 5 minutes, and has now stopped working. Yet that link still takes me to the real RSS feed if i paste it into my web browser.
If anyone can help, that would be great!

Cannot resize image

I opened up PSE 4.0 today and I resized an image and it said that it was resized (6x9 became 5x7, for example), but when I dragged it to my project, it was still the same size (not smaller)! Prior to today, it has always been the size that I wanted it to be. I have not changed anything in PSE so I am wondering if anyone knows how to fix this so I can resize images again.
Thanks so much!

Hey Erica,
You can resize the image using the move tool even after placing it in the project.
Cheers,
Chhaya
