One of the big advantages of using eRez is that you can work in real-time with an image no matter how large the image files are. In order to make this possible the images must be stored in a format that supports resolution independence such as TIFF with embedded image pyramids or FlashPix. You can store images in these formats using common software packages such as Adobe Photoshop and Paint Shop Pro.

A free utility program named “Khufu” can be used to automatically convert large image archives to TIFF using Adobe Photoshop 7.
eRez also supports JPEG files. But because JPEG files are not resolution independent the format is only suitable for low resolution images.

No, Khufu can be used to batch convert whole archives while preserving your existing folder structures.

It is available for free if you contact our support department.

No eRez is complete standalone software package that works fine without a Database. You can organize your images in a folder structure on the server that makes it easy for users to locate individual images without the need for a database. You can even add notes, keywords and other information to the individual images in the same way that you would do in a database. But instead of storing this information in a database it is embedded inside the image files in a standard IPTC format.

When the number of images on the server exceeds the permitted number the server will switch to “demo mode” and all images created will have an embedded YaWah.com watermark in the middle of the image.

The SOAP SDK is a Software Development Kit that allows programmers to use the functionality of the eRez Image Server from their own programs. The SOAP SDK comes with some sample programs written in the Java language for building your own searchable database using MySQL and creating “hot folder” automations.

No the maintenance program is an option for customers who wants to stay up-to-date without having to pay upgrade fees whenever a new major version is released. The maintenance fee must be purchased no later than 30 days after the software. Most customers buy the maintenance program along with the software.

The Image Server itself takes up around 50 Mb of hard disk space.

With an average size of 10 Mb per image, around 100 images per Giga Byte. Naturally the size depend heavily on the resolution and compression method used when storing the image.

800 MHz Pentium III or better recommended.
Minimum 128 Mb free RAM memory (256 Mb recommended).
50 Mb free hard disk space plus additional space for images.

Any Java2 enabled operating system, such as:
Microsoft Windows® NT, 2000 or XP.

• EPS • PDF • JPEG • TIFF
All formats support embedded clipping path, ICC profile and IPTC information. Images can be uploaded as JPEG, FlashPix or TIFF and are automatically optimized by the server. IPTC metadata can be edited from a browser.
The eRez 3 also supports other file formats. A new plug-in facilitates rendering, previewing and zooming into PDF, EPS and Illustrator files as well as handling of a wide range of other file types.

• JPEG • Flash • PNG • PDF • TIFF
These formats can be delivered “live” to any web page by means of simple http requests.“Publish to Web” function enables quick and easy publishing of images on the Internet – as a single image, a collection of images, a Flash Slideshow or a zoomable and navigable FSI Showcase.

For optimal rendering speed, master images must be saved with embedded “Image pyramid” data. TIFF images with pyramid data are 100 % backwards compatible.

TIFF images saved with pyramid data as well as FlashPix images will not be modified at all. Other formats such as JPEG images will be converted to TIFF after they have been uploaded. Clipping paths and other Photoshop resources as well as IPTC and ICC profiles are preserved during the conversion

Yes, all IPTC information such as copyright notices will be embedded inside the images as well as clipping paths and other Photoshop resources. Naturally the clipping paths will be adjusted accordingly when the image is cropped and/or rotated.
