Best image format to ensure compatibility

Hi folks, here's my big question.
-I've been using jpeg format for our logo on email to ensure compatibility with other mail app. Is this still the rule?
That brings me to my other question: Is there a way to put an higher resolution image and force it to display at 72dpi? The purpose of my question is that i would like to be able to attach our company logo on our email (1 inch large) and be able to print it witout pixelisation.
Can this be done?
Thx

Ideally, GIF format is mostly for web graphic art work,
simple artwork (non-image ones). While JPG format is specially
formatted for web images (or photos).
Does that help? You would also get some help about this issue
in Fireworks relatively pretty darn fast, I believe.
Cheers, Brian

Best image format for websites

I make website named Softec Labs and I often use the JPG format to save most of my images because of the image clarity and sharpness. I have been hearing that the PNG format is ideal for the web because of its small file size, does the PNG format look as good as the JPG formats? And is there a slider to change the image quality like there is in photoshop for JPG's?

JPEG is a "lossy" format. That is, it throws information away (or, sorta, does random smoothing) to reduce the size. When you choose the quality setting you are deciding how much to throw away; at highest quality settings nobody will ever see, for photographs. JPEG is designed for photos (the "P" in JPEG), and a poor choice where there are non-photographic sharp edges, such as in text, as these produce more noticeable loss.
By contrast PNG is not lossy - it is "lossless". So no quality setting is needed. There are other options for reducing size, like reducing the number of colours.
So a PNG will be exactly like the original (at least if you don't reduce colours). PNG can be a very good choice for solid areas of colour as in text; GIF is also suitable for these and has slightly wider support (though I think all mainstream browsers now support PNG).
For size, just do your own experiments. Thanks to Save for Web, you don't even need to save to compare quality and size.

Slideshow in Encore, best image format

I have imported an HD timeline into encore CS4, and generated two short slideshows (JPEG). When I transcode and burn a Standard Definition DVD, the slide show images are terrible ( grainy, exposure problems,etc). The JPEG images look good on my computer screen when I render the slideshow in encore. The slideshow has audio, also. Do I need to use a different file format for the slideshow images ? Thanks for any help. Jean Matusik

Ok Jim, thanks for the response. I will import the images into PP CS4 and try that. If Adobe purports the slideshow as a feature of Encore, it ought to work? I have gotten the slideshow feature to work well on a HD-blu ray project using the same size images for a different project and just wonder why the same size images (different subject) look lousy in SD DVD? Jean
But are they really the same size?
SD is 720 x 480 and HD is up to 1920 x 1080, and your original JPRG images may well have been automatically resized to fit, and a JPEG is lossy encoding anywayt (zoom right in 7 see how blocky things get).
HD may well be keeping them the same size.
I would try to use lossless TIF or BMP images to keep quality the highest possible anbd edit a sequence using Premiere instead of the Encore Slideshow

What is the best image format to use for importing images into a Pages document?

Image quality is good in photoshop. I am currenlty saving as .tiff at 300 dpi but when I import the image in the resolution diminishes radically.

I like to use .png or .pdf.

Image format... gif, jpg, targa

Well our graphic artists says targa is the best image format to use with games etc.
However, java does not support it?
What format should we use? Jpg was said to be too slow and gif to support to few colors...

RE: "A quantitative measure of lossiness is a useful
thing." - there are various existing formulas, though
there is a difficulty over a commonly agreed scale
that can be applied to all instances, I think it's
something like 'Cillic' - ? Can't find any info on 'Cillic'.
And yes, 'Discrete CT' -hmmm, you seem to
enjoy correcting people and putting people downNot true. You must not have read the part about "the only reason I'm correcting you is that the name is signicant". The "discrete" part is very important. If you would have typed something like "discrete sine transform" or something, I wouldn't have said anything, because I did know what you meant. And even if I couldn't figure out what you meant, I wouldn't have said anything about it any way because it wouldn't have mattered. It's like if you said "Fourier Transforms" were useful. I would have corrected that because "Fourier Transforms" and "Fast Fourier Transforms" are different things.

What is the best format to import images into iBA? How should I compress my images before importing? What is the best file format? PNG? Jpeg?

What is the best format to import images into iBA? How should I compress my images before importing? What is the best file format? PNG? Jpeg? I'm trying to figure out the best file format / compression for importing images into iBA. Also, does anyone know how iBA will compress the file? Are the assets attached (like a website) or flattened out? Does anyone know how iBA handles this? Many many thanks to anyone with insight into this.

This question is largely answered by the following thread...

Best file format for linked images in AI

Goal: To keep Illustrator "running" as smoothly as possible with a few hundred linked images?
Question: What file format to use for the linked images ???
I have a few hundred grayscale and CMYK scans that are placed in AI. for a very large museum mural. The scans only have a single layer. They are currently jpegs but Illustrator in coming to a crawl and randomly crashing.
In my everyday work flow I usually link to PSDs
Just wondering what the absolutle best file format is to squeeze every bit of performace out of illustrator with so many linked images.
Thanks in advance,
Dan

Jpegs are compessed in such a way thata a jpeg of a smaller takes a little longer size to open.
You are probably experiencing this on alrge scale so it is more noticeable and making it take longer to link up.
I would use tiffs anyway.

Image format for best quality photos

Hi there, I'm pretty new to photo-editing and have a question about preserving image quality:
I've heard that re-saving jpegs in Photoshop (Elements 12) makes them lose quality - even if no editing is done - and that saving jpegs in formats like PNG and TIFF can preserve the quality of the original image. So, if I edit a jpeg image in PSE and then save it as a TIFF, does that mean the quality of the original image is preserved 100%? If not, how can I fully retain the quality of jpegs after editing and saving them?
Thanks for your help

Hi Phoebe2014,
Yes you are right that each time you open and save a jpeg image , the image compresses and you lose small amount of information. As i believe that it should not lose quality of image when you are saving a jpeg image to tiff format because compression occurs when you re-save a jpeg image to jpeg format. You can read more on below links.

There may be a few links in Apple Support, regarding articles about how to use iBooks Author
and iBooks Store, etc; these would be separated into two general categories by device used.
Since there is an iOS and an OS X version of each, you may have to look to see what Apple
Support says about the one you are interested in; and how far their database goes toward an
answer to your question. Otherwise, a general search engine approach may be necessary.
Not sure if anything along the lines of what you seek would be available in an App.
References to iBooks Author and iBooks Store, etc appear within these two categories in Support:
For Mac OS X:
http://www.apple.com/support/mac-apps/
For iOS:

Appears a community host moved your earlier post into one of the iBooks Author or Store sections
after I'd replied to what otherwise may be a similar post. Not sure if the links to the Discussions area
of iBooks you are interested in, have similar questions or answers by others who'd visited previously.

What is the best image size format for imovie iOS

I want to create a few black images with white letters as title slides and use them with some of my videos I am creating using imovie with my new ipad3.
What is the best image size?
thanks!
Jeremy

It all depends on what you want to do with the images.
If you don't want to do any moves on the images then make them the exact size of the video.
The iPad 3 edits in full HD, 1920 x 1080.
If you want to do small moves, then make is larger.
But keep the 1920 x 1080 dimensions otherwise iMovie just chops the image to that ratio.
good luck

Best File Format For Online Line Art?

I thought the conventional wisdom was that all line art for the screen should be saved as GIFs, all photographic line art should be saved as JPEGs.
Then PNGs came along and offered an alternative to GIFs.
I've been exploring this because I've been having a problem when exporting line art from Illustrator 8 as a PNG and opening it in Fireworks MX, where it appears washed out.
I did a bit of research among comic strip artists -- the art I'm exporting from Illustrator is a comic strip -- and came up with conflicting results.
Dilbert seems to save black and white line art as GIFs, e.g. http://dilbert.com/comics/dilbert/archive/images/dilbert2008611230313.gif
... But its Sunday colored strips seem to be saved as JPEGs, e.g. http://dilbert.com/comics/dilbert/archive/images/dilbert2008040261966.jpg
Meanwhile Donnesbury seems to save colored comic strips as GIFs, e.g. http://images.ucomics.com/comics/db/2008/db080406.gif
Any thoughts, suggestions?
Thanks.

I assume your line art is drawn as vector art in Illustrator, correct?
As far as I'm concened, the "best file format for online line art" would be .swf, because it would retain its scaleable vector nature, and the Flash Player is most likely embedded in any reasonably recent computer's browser.
But a little simple experimentation would be in order regarding file size. SWF (as exported from Flash, not necessarily AI) is very efficient. But the complexity of the line art could still make a given image require more bandwidth as .swf than as a rasterized version.
The former conventional-wisdom regarding PNG is the old "not supported in older browsers" saw. I see even Firworks's online help still says:
> However, not all web browsers can view PNG graphics.
Personally, I think its way past time to stop cow-towing to outdated browsers and use PNGs anyway. So if it were me, and the nature of my line art required rasterization for online use, I would use PNG for its obvious advantages. But then, my livlihood is not affected by some minority of outdated web viewers not being able to view my PNGs.
I would think that whatever color problems you are having in getting your AI files exported to PNG can be worked out with a little investigation/experimentation. (PNG supports color management profiles, so that alone may be your problem, and may be easily fixed in your workflow.) GIF is by definition limited to a subset of colors. JPEG is by definition a lossy compression format. So there are certainly precise color-accuracy issues with those overused formats, too.
But again, that's just me. What little I do in web graphics that would involve this issue doesn't really affect my livelihood. Lowest-common-denominator compatibility may be more important to you.
> Gilbert seems to...
> Doonsbury seems to...
The two images are very close to the same size (132K & 125K). They both include contone grads. Between JPEG and GIF, I would expect JPEG to more consistently yield acceptable results. Since GIF is limited to an 8-bit lookup table, I would expect aberations such as unwanted banding to be more likely in GIF if the artwork contains many colors and alot of highly-rendered shading.
Since you specify
line art, though, that would rule out contone fills, and you could use GIF with a very small color table.
On the other hand, you do not specify whether you want to use transparency in your line art images. If you do, PNG would be far superior, because it supports true alpha transparency. In a GIF, if you can only make one particular color transparent. So even with line art, if the line art is antialiased at all, you'll have the ugly halos so commonly seen in GIFs when displayed on a wrong-colored background.
The only functional "advantage" that I see in GIF over PNG is its multi-image capability, for quick & dirty frame-by-frame animation. My personal animation efforts focus entirely on Flash/SWF, and use scripted animation whenever possible to avoid frame-by-frame. But I recognize the simplicity convenience of animated GIFs for web banners and those (often-annoying) moving icons and such.

HowTO: convert Image- byte[] when don't know image format?

I have byte[] field in my DB. Images have been stored there.
Images can be jpg/gif/png.
My task is to scale them and save back (to another field)
I have such code:
I know, that getScaledInstance is bad, but please, don't pay attention. This operation +(massive image resizing will be performed once a year at night)+
public class ImageResizer {
     private static byte[] resizeImage(byte[] sourceImg, int newWidth){
          byte[] result = null;
          Image resizedImage = null;     //output image
          ImageIcon imageIcon = new ImageIcon(sourceImg);     //source image
          Image imageSource = imageIcon.getImage();
          int imageSourceWidth = imageSource.getWidth(null);
          int imageSourceHeight = imageSource.getHeight(null);
          if(imageSourceWidth > newWidth){
               float scaleFactor = newWidth/imageSourceWidth;
               int newHeight = Math.round(imageSourceHeight*scaleFactor);
             resizedImage = imageSource.getScaledInstance(newWidth, newHeight,Image.SCALE_SMOOTH);
             Image temp = new ImageIcon(resizedImage).getImage();// This code ensures that all the pixels in the image are loaded.
             // Create the buffered image.
             BufferedImage bufferedImage = new BufferedImage(temp.getWidth(null), temp.getHeight(null),BufferedImage.TYPE_INT_RGB);
             /**And what next?*/
          }else{
               result = sourceImg;
          return result;
     public static byte[] scaleToSmall(byte[] sourceImg){
          return resizeImage(sourceImg, 42);
     public static byte[] scaleToBig(byte[] sourceImg){
          return resizeImage(sourceImg, 150);
     public static byte[] serializeObjectToBytearray(Object o) {
         byte[] array;
         try {
           ByteArrayOutputStream baos = new ByteArrayOutputStream();
           ObjectOutputStream oos = new ObjectOutputStream(baos);
           oos.writeObject(o);
           array = baos.toByteArray();
         catch (IOException ioe) {
           ioe.printStackTrace();
           return null;
         return array;
}On this forum I've found many solutions, but approximately all of them suppose that I know file format (PixelGrabber, ImageIO, e.t.c). But I don't know it. I know, that it can be jpeg/gif/png.
What can I do?
I've found that simple serialization can help me (+public static byte[] serializeObjectToBytearray(Object o)+), but seems like it doesn't work.
Edited by: Holod on 01.11.2008 10:18

Here I came up with one possible solution using some more functionality of ImageIO.
public class ImageResizer {
    private static byte[] resizeImage(byte[] sourceBytes, int newWidth) throws Exception {
        byte[] scaledBytes;
        // ImageIO works with Files or Streams, so convert byte[] to stream
        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(sourceBytes);
        // Why not just use ImageIO.read(inputStream)? - Because there would be
        // no way to know the original image format (I am assuming here that
        // you need to write back the image in the same format as the original)
        ImageInputStream imageInputStream = ImageIO.createImageInputStream(byteArrayInputStream);
        // assuming there is at least one ImageReader able to read the image
        ImageReader imageReader = ImageIO.getImageReaders(imageInputStream).next();
        // save image format name so we can write it back in the same format
        String formatName = imageReader.getFormatName();
        imageReader.setInput(imageInputStream);
        BufferedImage sourceImage = imageReader.read(0);
        int imageSourceWidth = sourceImage.getWidth();
        int imageSourceHeight = sourceImage.getHeight();
        if (imageSourceWidth > newWidth) {
            // be careful with integer divisions ( 500 / 1000 = 0!)
            double scaleFactor = (double) newWidth / (double) imageSourceWidth;
            int newHeight = (int) Math.round(imageSourceHeight * scaleFactor);
            System.out.println("newWidth=" + newWidth + ", newHeight=" + newHeight + ", formatName=" + formatName);
            // getScaledInstance provides the best downscaling quality but is
            // orders of magnitude slower than the alternatives
            // since you're saying performance is not issue, I leave it as is
            Image scaledImage = sourceImage.getScaledInstance(newWidth, newHeight, Image.SCALE_SMOOTH);
            // Unfortunately we need a RenderedImage to use ImageIO.write.
            // So the next lines convert whatever type of Image was returned
            // by getScaledImage into a BufferedImage.
            // Using TYPE_INT_ARGB so potential alpha channels are preserved
            BufferedImage scaledBufferedImage = new BufferedImage(newWidth, newHeight, BufferedImage.TYPE_INT_ARGB);
            Graphics2D g2 = scaledBufferedImage.createGraphics();
            g2.drawImage(scaledImage, 0, 0, null);
            g2.dispose();
            // Now use ImageIO.write to encode the image back into a byte[],
            // using the same image format
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
            ImageIO.write(scaledBufferedImage, formatName, byteArrayOutputStream);
            scaledBytes = byteArrayOutputStream.toByteArray();
        } else {
            // if not scaling happened, just return the original byte[]
            scaledBytes = sourceBytes;
        return scaledBytes;
    public static void main(String[] args) throws Exception {
        // this is just for my own local testing
        // simulate byte[] input from database
        BufferedImage image = ImageIO.read(new File("input.jpg"));
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        ImageIO.write(image, "PNG", byteArrayOutputStream);
        byte[] sourceBytes = byteArrayOutputStream.toByteArray();
        byte[] scaledBytes = resizeImage(sourceBytes, 640);
        // write out again to check result
        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(scaledBytes);

How to change the bar chart rendering image format in SSRS

Hello all,
I am working with SQL Server 2008 R2 and I have a SSRS bar chart report, when the report got rendered over online or if the take Export (PDF and PPT), the image is in png format always, which is taking too much of time to execute the report in case of large
data.
Can, It be possible that the rendered image is in jpeg format instead of png.
If Yes, please share the appropriate steps to follow:
Thanks in advance
Pankaj Kumar Yadav-

Hi Pankaj067,
According to your description, you want to change the bar chart rendering image format as JPEG format when previewing the report or exporting to a PDF file .
In Reporting Services, the chart rendering image format is PNG by default. It’s a by-design behavior. And it doesn’t open any API for us to change the image type when exporting a chart to a format. So in your scenario, your requirement can’t be achieved
in Reporting Services currently. I would recommend you submit a feature request to Microsoft at this site:
https://connect.microsoft.com/SQLServer. So that we can try to modify and expand the product features based on your needs.
If you have any question, please feel free to ask.
Best regards,

Image cannot be rendered because Aperture does not support image format

Dear all,
I have installed apple Aperture 3.03 and the complete Nick software plug-in selection:
• Dfine 2.0 for Aperture
• Color Efex Pro 3.0 Complete for Aperture
• Silver Efex Pro for Aperture
• Sharpener Pro 3.0 for Aperture
• Viveza 2 for Aperture
History
Until a few days ago the system was running ok / no notable issues on performance. / all pug in seem to run good / no issues. Also
• I Run OSX10.4/ Aperture 3.03 ( 32Bit mode)
• My library contains just over 10000 images / approximately 140GB
• I have recently updated the OSX software update including the security update 2010-005
• as well as the Snow leopard graphic update 1.0
• As far as I am aware all updates where automatically recommended by OSX Software update ( no manual intervention).
• As far as I remember after update the system still was running ok but honestly I can not tell you how many times the Nick Plug in started out of Aperture.
After all, Several times I continued using the system / still no noticeable problem until the following was happening:
Problem:
After creating with "PT gui" a panoramic image File type: "TIF" Pixel size: 5112 × 2556 (13,1 MP) I imputed this file in to Aperture (drag and drop). During the attempt to eddied this file with "Nick Define 2.0" the system was hamming up No response for several minutes from Dfine 2.0 / Aperture" At the end I had to "force quit" the applications.
After the consequential reopening of Aperture I tried again to eddied images with any Nick software Plug-In but each time Aperture prepares any image previously stored in my Library ti open the Pug in the following Error message appears:
*"This image cannot be rendered for editing because Aperture does not support the image format"*
Currently non of my previously in the library safed images can be opened in a Nick software Plug-In this applies to all file types I have tied " Raw, tif, jpg"
• I am still able to eddied normally with Aperture ( so far I do not find any other issue)
• A newly imported Raw image after being taken with my EOS 5D can be edited in the completed Nick software Plug-In selection ( so far I do not find any other issue)
The following actions have been taken to overcome the issue (all not successful):
• I restored my Library out of my back Up ( to previous time of event ( no Time machine back up)
• Uninstallation of all Nick software Plug-In selection
• Uninstallation Aperture Reinstallation Aperture / Nick software Plug-In selection
• Repairing the library ( all three possibilities)
• installation of latest EOS utilitys
Questions
• Can you support me to overcome this issue?
• Have you heard similar issues of Nick user Running the Aperture plug-ins?
For me it is really strange that even after replacing the the library in my normally not connect back up the problem still exists (this should be not affected by the event as the back up was not done any more) / new imported images are editable with the Plug-In.
I would be happy if you could support me in this issue.
Best regards,
Matthias
PS: I have reported this issue to Apple (via Aperture feedback) as well as contacted the Nick software support and currently waiting for feedback.

Dear Ma-Le / All
I have just had the same problem
I use
• Aperture 3.03 with a iMac 2.8 Intel Core 2 Duo with all files on external hard disks (mac extended fomat as apple suggests) with referenced masters.
• Camera Nikon D300, with probably 75,000+ images on 2 hard drives
• Photoshop CS2 with PhotoTools 2.5 plugin
This has been working perfectly until yesterday when the system froze when I was using PhotoTools 2.5 with Photoshop CS2 - as a result of which I resorted to a force quit.
Since then on most of my files it has not been possible to use an external editor.
A message appears saying: *Editing Error - This image cannot be rendered for editing because Aperture does not support image format*.
The problem seems to apply to the attempted use of any external editor (including Noise Ninja)
The following have each been tried, all unsuccessfully:
- Using each of Aperture's library 3 first aid options
- Rebuilding directory using Diskwarrior
- Checking for virus using Virus Barrier X4
- Defragmenting library hard disk using TechTool pro
- Changing permissions settings
- Using Disk Utility first aid to repair permissions and checking main disk
- Removing some plist elements when open 'show package contents' of library
- Setting up a(n almost clean) new system, with newly loaded version of Aperture, with a new library from a vault saved prior to the crash when the problem first occured
Several things seem to me to be totally bizarre:
1 - The problem is the same on the other library hard disk which was not in use at the time
2 - The problem still occurs when a back up vault saved prior to this problem is loaded - using a new hard disk with a new system and a newly reloaded and upgraded Aperture software
3- The problem seems inconsistent. It appears to affect some photos but not all. Even from the same shoot, some photos can be edited using an external editor, whilst others cannot (but as far as i can tell most of the photos in a particular album seem to be consistently affected)
4- The only way around it seems to be if I import a new (copy image) from the original master. Then everything works ok, and I can successfully edit that copy image in photoshop / phototools plug-in.
I am beginning to wonder whether what has been corrupted is Aperture's ability to make copies from the master file which it then uses with the external editor (I have no real idea whether this is correct)
Does anyone have any ideas or solutions - or has anyone else been suffering a similar problem?
Eric
PS: As a professional photographer this problem is a really serious issue for me - and I really don't really want to go to Lightroom or Capture One
