|
||
Actually, by adding the frametypes that have been discussed (excluding<br>
|
||
the MIME one), the standard would grow by about a page or two. <br>
|
||
<p>
|
||
Here's a piece of the language from that sane standard that addresses<br>
|
||
image formats and mentioned that "the interface has been defined carefully<br>
|
||
to allow extending it in the future". <br>
|
||
<p>
|
||
3.2 Image Data Format<br>
|
||
<p>
|
||
Arguably the most important aspect of an image acquisition system <br>
|
||
is how images are represented. The SANE approach is to define a <br>
|
||
simple yet powerful representation that is sufficient for vast <br>
|
||
majority of applications and devices. While the representation is <br>
|
||
simple, the interface has been defined carefully to allow extending <br>
|
||
it in the future without breaking backwards compatibility. Thus, <br>
|
||
it will be possible to accommodate future applications or devices <br>
|
||
that were not anticipated at the time this standard was created. <br>
|
||
<p>
|
||
Although it doesn't specifically say so, it seems to me that one<br>
|
||
mechanism put in place to allow extension is the frametype. And<br>
|
||
there certainly is no mention of the magical all encompassing mime<br>
|
||
frametype arriving to save the day.<br>
|
||
<p>
|
||
With the frametypes _JFIF, _JBIG, _G31D, _G32D, and _G42D what we are<br>
|
||
trying to do is "accommodate future applications or devices that were<br>
|
||
not anticipated at the time this standard was created" in the most<br>
|
||
straighforward and painless manner. <br>
|
||
<p>
|
||
Why is the process of getting there so painful?<br>
