A typical image editor will decompress and recompress a JPEG file when you save it, resulting in a loss of image quality. You can avoid this if you use special software that can do a very limited set of operations that don't involve recompressing, i.e., they just rearrange the data already in the file. You are typically limited to rotations at multiples of 90 degrees and some cropping actions: There are many others than I haven't listed. (See here for more.

Always modify your images while they are in a TIFF or RAW format. These are known as "loss-less" formats. Once your images have been sized to 1920x1920 pixels, save a copy of the image as a JPEG. Do not make any modification to a JPEG image, which is a "lossy" format. This means that each time you make changes and save a JPEG, your image will degrade. For further details, please reference Image Preparation. This is an ethical issue for artists and for each show, fair and/or festival.

Yes, although GIF and JPEG files are best suited for viewing on computer monitors. Due to compression, these image formats can occasionally lose unexpected detail or color. Small GIFs and JPEGs are an excellent way for us to preview your document quickly. If you are using a GIF or JPEG file as your finished artwork, please make sure that the image is made to the size that you want to print it and has a resolution of 300 pixels per inch or greater.

Gifs are usually only best for images where there are large flat areas of a single colour, such as a diagram. Gifs can have transparent areas in them, and can be animated, which a jpeg can't. Gifs are also limited to 256 colours. Jpegs are preferrable to gifs for almost any image that isn't a diagram. Jpegs compress the data very well, meaning that your picture files will be smaller. This compression creates inaccuracies though, but these inaccuracies are not usually noticeable.

Signal strength: This is basically determined by how close you are to an access point, and if anything is absorbing or deflecting radio signals. Interference from another radio frequency source: Unfortunately for 802.11b/g users, things like microwave ovens and 2.4GHz cordless phones operate in the same frequency band. These radio signals can severely degrade or completely destroy an 802.11b/g signal.

JPEG stands for Joint Photographic Experts Group, an association that has defined a standard image compression technique and file format that is supported by many different image editing programs. JPEG allows for adjustable levels of compression -- image quality goes down as you increase compression. Amazingly, the JPEG compression technique can reduce the size of an image by a factor or 5 to 10 with little or no visible image quality degradation.

No, sorry... there are numerous other sites online which will allow you to do this, but our services do not include this feature. [BACK TO TOP]

TIFF (Tagged Image File Format) is a flexible standard that it is widely supported by many image processing applications. We use TIFF for black & white images as the TIFF compression algorithm used is best suited to this application. JPEG on the other hand is used for its ability to compress colour image file sizes.

A) - In Internet Explorer right click on the gif or jpeg image. From the drop down menu select "save as" or "save target as". This will save the image to your default folder, which in most cases is the "my documents" folder. In Netscape right click on the gif or jpeg image. From the drop down menu select "save image as".

We have to limit the image size because re-sizing the images requires the web server to do quite a bit of work, and this slows down the website. Large images also require more disk space. JPEG images are used because they are easy to manipulate and provide a good trade-off between image quality and file size.

We accept over 30 different image file extensions that are created on different image creating software packages. Normally you will have a Save As... option which will allow you to specify what format you want your image saved as. Most applications will enable you to save as a .jpg as that is the most common file extension. However you cannot simply change the file extension to .jpeg, as you must use your image creating software to change this. Normally you will need to choose .

Set your mouse pointer on the image, click the RIGHT mouse button once, and release. A small menu will appear. Set your mouse pointer at the bottom of the menu on "Properties" (It will highlight), click the LEFT mouse button once, and release. A new screen will pop up. You should see several tabs across the top of the page. One of them will say "Summary." Click it. You should see a list of image properties. "Width" is the image width in pixels, and "Height" is the image height in pixels.

Even if you tell Photoshop not to alter your images when creating the gallery, it recompresses them with high compression when copying them over to the images directory for your gallery. The workaround is to copy and paste your originals into the image folder that photoshop creates for your new gallery.

Results will be reported using the Image Quality Receiver Operator Characteristic (IQROC) and Linear, Generalized Linear, and Generalized Linear Mixed Model frameworks. Information on IQROC can be found in the ICE announcement section on bbs.bee-biometric.org website, in the program manager presentation at the first Iris Challenge Evaluation (ICE) workshop.

We are very proud of the images in BAS publications and have worked hard to reproduce that same quality on the Web. In order to facilitate quick loading, we have reduced the resolution of the original artwork to 72 dpi.

JPEG is a standardized image compression process. (Joint Photographic Experts Group) A JPEG is designed to compress full color or gray scale photographs to aid in the ease of downloading from the internet, without compromising image quality. After downloading the compressed file, the photograph will be able to be opened at its full resolution.
