Image File Formats

ImageWarp supports the following standard image file formats: IWD (ImageWarp document), BMP (Windows bitmap), PCX (Zsoft Paintbrush), GIF (Graphic Interchange Format), TIFF (Tagged Image File Format), FITS (Flexible Image Transport System), TGA (Truevision Targa), JPEG (Joint Photographic Engineer Group) and AVI. It also supports a user-defined RAW format for reading and storing uncompressed images.

The following table shows which image types and what kinds of extended image data of ImageWarp are supported by specific file formats. Unsupported image types are automatically converted into the closest match before storing.

Image scaling information (unit, resolution, origin), as well as pseudo-color palettes and maps for gray images is stored in the IWD, TIF and FITS files only. Since ImageWarp uses a proprietary code for that, other programs can retrieve only the image but not this information.

ImageWarp recognizes GIF animations and AVI files and opens them as sequences. Image types supported by AVI format depend on the codec used for compression. Gray sequences can also be stored in TIFF and FITS formats.

JPG and AVI files can be stored with adjustable compression ratios (see Save Image for more details).

IWD is a proprietary ImageWarp's format that provides a lossless compression and supports all the extended data fields.
