Compression

[Rob Dillon]

Hi David,

If your images are jpeg or png, then link them to the cast instead of
importing them. Then place the linked files on the CD. The linked files
can be stored in their compressed file size and then at runtime they
will be decompressed as they are used by the Director movie.

If you fully import compressed media into Director, the files will be
decompressed and then stored in Director's format. This usually results
in a larger file.

There may be some performance hits when using lots of linked bitmap
files as the decompression and resulting memory control can take time,
but you can usually overcome this by controlling memory and asset use
through Lingo.

I forgot to mention that if you do create a Shockwave compressed projector,
you should include certain .dll files in an Xtras folder next to the
projector. These files are listed in the technotes about creating a fast-
start projector. If you do not include those files, users who do not have
Shockwave installed will be prompted to download and install Shockwave.

I recommend uninstalling Shockwave on your computer(s) during testing to
ensure everything will work. There is a Shockwave uninstaller available on
the Macromedia site.

Rob,

Many thanks for your suggestion; I have just spent the last hour trying it.

My problem arises from the necessity for the images to have transparent
backgrounds.

If I link to the images as jpgs or I get the halo effect what ever I do to
the image in Photoshop. If I take the same file and copy/paste it into the
cast as an internal cast member there is no halation but of course director
turns it into a bitmap which is much naturally larger than the compressed
file.

Interestingly if I import the file into the cast via drag/drop rather than
pasting, although the file size in Director similar to that created by
pasting, halation is present.

If I convert the file to a CompuServe gif and link to it there is no
halation but the edges of the image are serated in Director, (but not in
Photoshop...).

Quite apart from my desire to make the movies/Projector a small possible I
would be interested to know why I get the effects described above...

Check the properties inspector -> Bitmap -> compression
should be standard.

Hi,

What's the best software for compression of swf files? I have some 160x600 banner ads that need to be 30k or less.

Thanks!

I've used 'SWF Compressor-Decompressor 2.0.1' before, and it works pretty good.
