EPSF Files
EPSF graphics can be positioned anywhere in the output image and subjected to
translations, rotations and scales.EPSF files are rendered to images by the 5D Jaws
PostScript interpreter and RIP, which is fully Level 2 compliant.

About Fonts
Jaws uses fonts in Adobe Type 1 format stored in the directory:
Two very simple command line programs are supplied that convert Macintosh and PC Type 1
fonts to Unix format. These are called mac2ps and pc2ps respectively. To use
them, you must transfer the font file to convert from your Macintosh or PC to your SGI
machine using some method, which does not corrupt the contents (e.g. use binary mode FTP
rather than ASCII mode). Unfortunately, we cannot advise you on the specifics of
transferring data between PC's and (especially!) Macintoshes and SGI machines.
As an example, to convert a Type 1 font file from a PC environment, containing the
Times-Roman font and called "TIB_____.PFB", you would use:
This will create a file in the current directory which is the name of the font
contained in the font definition. In this case, the file will be called
"Times-Roman". You then copy this file to /usr/local/jaws/fonts, and Times-Roman
will then be available. (Times-Roman is, of course, one of the fonts supplied with Jaws,
but you get the idea...).
pc2ps and mac2ps are installed in the /usr/local/jaws/bin directory, so
you will need to have this in your PATH, or type the full name to run these programs.
Please note that FONTS ARE COPYRIGHT. We cannot supply any fonts other than those that
come with Jaws. Please respect the licensing agreements of other font suppliers.
Having to have matching fonts on the creating and rendering machines is definitely a
nuisance. While you can include representations of fonts in PostScript documents
sometimes, this is not generally true of EPSF files. There is simply no way around this.
Problems with fonts is one of the reasons Adobe invented the PDF format!
Select Any Clip: the input clip is totally ignored but Jaws need a base to
work from.
Specifies the spin applied to the selected region when Zoom/Transform is On. The
region selected is first translated and scaled until it fills the output image. The output
image (in effect) is then rotated about its center by the spin amount.
The center of the region selection box on the untransformed input EPSF graphic.
X/Y scale factor.
Anti Aliasing Samples (Min: 1 Max: 5 Default: 4)
Oversampling factor to use when rendering. Setting this to 4 or 5 is recommended, as Jaws
isn't significantly slower doing good anti-aliasing than not (in most cases).
search
Click for a file browser to locate the epsf file you want to render. The file chosen will
be displayed in the EPS File box.
Displays the name of the EPS (or PostScript) file being processed. You cannot type
directly into this text box.
From Macintosh? (Default: Off)
Off: if the EPSF file was NOT created on a Macintosh.
Off: the input file is assumed to be a true EPSF format file.
On: tries to process PostScript (i.e. PostScript data intended to describe one or more
whole pages as usually sent to printers, etc., as opposed to a set of graphic
elements intended for inclusion in another document). While this will usually
work, it is impossible for the translations, rotations and scales specified in
Jaws to work correctly, since there are transformations embedded in
PostScript files which cannot be undone.
Also, ALL PAGES of the input file will be processed and the results superimposed
on one another! This is generally not a good idea... To stand a chance of
working, the PostScript file MUST contain a valid bounding box specification
(as all EPSF files do).
Off: ignores any embedded thumbnail description.
On: tries to read and display thumbnail images. Jaws can only
cope with TIFF format thumbnails in EPSF files with a Windows binary header,
or with device independent thumbnails supposedly found in EPSI files.
Actually, the device independent thumbnails in EPSI files possibility hasn't
been tested, because we cannot find anything that generates EPSI files!
Shows how much the world really values portability, I guess.
Zoom/Transform (Default: Off)
Apply the geometric transformations you have specified to the EPSF file when
rendering it.
Off: the entire EPSF graphic (or PostScript page) will be rendered centred in the
output image at the largest scale at which it will entirely fit inside the output image.
This is a good starting point. Based on this, you can use the overlay tools to draw a box
around the part of the graphic that you want to fill the output image. You can also
specify a spin as described below.
On: when you have selected the region you want to fill the output image,
turn Zoom/Transform On and the transformations will be applied. The overlay region selection box and spin
controls are available only when Zoom/Transform is Off, as that is the only time at
which they make sense.
Note: transformations cannot work correctly with PostScript (i.e. non-EPSF)
input files.
Off: the image can be stretched/squashed as the aspect ratio is not
preserved if the Zoom factors do not match.
On: match the X and Y zoom factors, preserving the aspect ratios of
elements in the input EPSF graphic. The X Value is used.
Working with images
If you have a really high resolution image and you would like to pan around in and/or zoom
into it at TV resolution, Jaws is just what you need! You can see the whole
image and then set up the desired region and orientation; key framing the sequence to
create the output clip. Jaws renders the output using the full input resolution.
However the input image must be in epsf format. If you do not have conversion tools please
contact 5D.
EPSF can be output by a large number of useful packages such as Iris Showcase on the
Silicon Graphics platform and Adobe Illustrator on Macintoshes and PC's. EPSF contains
"vector descriptions" of graphical objects, which can be rendered at, for
example, large magnifications, while retaining their integrity. This does not apply to all
raster images, which can also be represented in EPSF files. The source image epsf file
must be very high resolution and you want to render areas of it at TV resolution (see
above, Working with images).
Jaws (the RIP) is supplied with Jaws (the plug-in). Jaws(the plug-in) will
not work if Jaws (the RIP) has not been installed.
Although Jaws will attempt to render PostScript (PS) files (and will usually
succeed!), these files describe the placement of graphics on one or more pages, and
contain their own internal transformations to position things correctly on the pages.
Jaws cannot undo these transformations, so translating, rotating and scaling
specified on PostScript files will not work correctly.
To have any hope of working, the PostScript file must contain a valid bounding box
specification. Most PostScript files do have this.
In order to render text correctly, Jaws must have access to the fonts used when the
document was created. This means these fonts must be present on the machine running Jaleo.
If the required font is not available when an item of text is rendered, it will be
drawn using the Helvetica font, and it is very likely that the character spacing
will be totally wrong.
/usr/local/jaws/fonts
Jaws comes with 67 Type 1 fonts. You can add other fonts to
/usr/local/jaws/fonts at any time. They must, however, be in Unix Adobe Type 1 format.
Type 1 fonts are often supplied in Macintosh or PC format rather than Unix format.
