What is this plug-in?
|
||||
---------------------
|
||||
|
||||
This is a Linux/Mozilla plug-in that enables a scanner/digital
|
||||
camera application to be created with JavaScript. To this end
|
||||
the SANE plug-in provides two things:
|
||||
|
||||
1. I have attempted to export all of the SANE API's
|
||||
from the SANE native libraries to JavaScript.
|
||||
(I have provided two brain-dead samples for a
|
||||
CPia USB digital camera and HP 6300 scanner.)
|
||||
|
||||
2. A drawing surface for displaying the scanned image.
|
||||
|
||||
=====================================================================
|
||||
|
||||
Why did you bother?
|
||||
------------------
|
||||
|
||||
Originally, I used this plug-in to cut my teeth on the new Mozilla
|
||||
XPCom plug-in model. Now I am hoping to provide a Linux/Mozilla
|
||||
plug-in sample that exercises most of the functionality that the
|
||||
Linux community would want to use (like connecting JavaScript
|
||||
to native code.)
|
||||
|
||||
=====================================================================
|
||||
|
||||
You know, Linux isn't the only UN*X around!
|
||||
-------------------------------------------
|
||||
|
||||
I say Linux because that is the only platform I have built/tested on.
|
||||
SANE is supported by a long list of UN*X OS's so there is no reason
|
||||
that other platforms shouldn't work with this plug-in.
|
||||
|
||||
(I have tried to stick to NSPR functions for this reason, but it's easy
|
||||
to over look a couple of Linux specific functions.)
|
||||
|
||||
======================================================================
|
||||
|
||||
How do I build this beast?
|
||||
-------------------------
|
||||
|
||||
In order to build this plug-in, you need the SANE (Scanner Access
|
||||
Now Easy) libraries/headers installed on your system. For more
|
||||
info on SANE, go to http://www.mostang.com/sane.

What is this plug-in?
|
||||
---------------------
|
||||
|
||||
This is a Linux/Mozilla plug-in that enables a scanner/digital
|
||||
camera application to be created with JavaScript. To this end
|
||||
the SANE plug-in provides two things:
|
||||
|
||||
1. I have attempted to export all of the SANE API's
|
||||
from the SANE native libraries to JavaScript.
|
||||
(I have provided two brain-dead samples for a
|
||||
CPia USB digital camera and HP 6300 scanner.)
|
||||
|
||||
2. A drawing surface for displaying the scanned image.
|
||||
|
||||
=====================================================================
|
||||
|
||||
Why did you bother?
|
||||
------------------
|
||||
|
||||
Originally, I used this plug-in to cut my teeth on the new Mozilla
|
||||
XPCom plug-in model. Now I am hoping to provide a Linux/Mozilla
|
||||
plug-in sample that exercises most of the functionality that the
|
||||
Linux community would want to use (like connecting JavaScript
|
||||
to native code.)
|
||||
|
||||
=====================================================================
|
||||
|
||||
You know, Linux isn't the only UN*X around!
|
||||
-------------------------------------------
|
||||
|
||||
I say Linux because that is the only platform I have built/tested on.
|
||||
SANE is supported by a long list of UN*X OS's so there is no reason
|
||||
that other platforms shouldn't work with this plug-in.
|
||||
|
||||
(I have tried to stick to NSPR functions for this reason, but it's easy
|
||||
to over look a couple of Linux specific functions.)
|
||||
|
||||
======================================================================
|
||||
|
||||
How do I build this beast?
|
||||
-------------------------
|
||||
|
||||
In order to build this plug-in, you need the SANE (Scanner Access
|
||||
Now Easy) libraries/headers installed on your system. For more
|
||||
info on SANE, go to http://www.mostang.com/sane.
