<EM>> the format to be
|
|
</EM><BR>
|
|
<EM>> portable so that it can be used by all software.
|

<EM>> Are there other
|
|
</EM><BR>
|
|
<EM>> considerations that I have neglected?
|

|
|
<P>tiff can save arbritary information in "tags" which
|
|
<BR>
|
|
sometimes other programs cant read, for example a tiff
|
|
<BR>
|
|
saved in photoshop has a pair that gimp cant read. but
|
|
<BR>
|
|
this can save information like an ICC profile or gamma
|
|
<BR>
|
|
information. png is probably the smallest portable
|
|
<BR>
|
|
format, but the only thing it saves besides pixel data
|
|
<BR>
|
|
is gamma. another advantage of tiff is the ability to
|
|
<BR>
|
|
store more than one image in a file. an image viewer
|
|
<BR>
|
|
can use this to read/write thumbnails and the like.
|
|
<BR>
|
|
<P>gif is also a bad choice because of its limited color
|
|
<BR>
|
|
depth (256 color pallet). if you want to avoid
|
|
<BR>
|
|
proprietary nastiness make sure you dont save tiffs
|
|
<BR>
|
|
with LZW compression. PNM is simply the easiest format
|
|
<BR>
|
|
to read/write and probably the most portable since
|
|
<BR>
|
|
images can be stored in plain text.
|
|
<BR>
|
|
<P>overall, tif is the most flexible and should probably
|
|
<BR>
|
|
be your default, with png for when you need smaller
|
|
<BR>
|
|
file sizes.
