Well, Andreas seems primarily to be concerned about indentifying a frame<br>
|
||
type to the user in the event that it's not natively understand by an<br>
|
||
old backend. Honestly I don't think this is a serious problem is real<br>
|
||
world use, but it's easily overcome without using the (IMHO) rather<br>
|
||
unfriendly quasi-human-readable MIME types.<br>
|
||
<p>
|
||
We can simply associate a short text string with each defined type, in<br>
|
||
the standard and in backend header files, and any frontend which can't<br>
|
||
handle the data format it receives (presumably because of a user<br>
|
||
advanced setting or badly behaved backend) will just look in the<br>
|
||
getparm results for "frame_description" and say...<br>
|
||
<p>
|
||
Sorry, I can't handle image data in the format:<br>
|
||
<insert short description here><br>
|
||
Save to a file anyway? (Y)es / No<br>
|
||
<p>
|
||
The other point which _keeps_ being made by proponents of MIME in this<br>
|
||
debate is that there will "inevitably" be a huge number of formats to<br>
|
||
support -- yet this is hardly bourne out by an examination of MIME<br>
|
||
or by looking at scanners "In the wild". The four new data formats<br>
|
||
(and two other formats) suggested by backend writers so far seem to<br>
|
||
cover a broad range of high-end scanners.<br>
|
||
<p>
|
||
Before you make this argument again, I want _evidence_ that we're going<br>
|
||
to be swamped by more image formats.<br>
|
||
<p>
|
||
Further, I think SANE's use of standards-based formats (like JFIF)<br>
|
||
is important because SANE is also a Free Software project. Wherever<br>
|
||
we have a choice we should encourage Open standards rather than<br>
|
||
Proprietary technology. In the backend we have little choice, but<br>
|
||
in the SANE protocol and API we *do* have a choice.<br>
