Hello,
<BR>
<P>hp-backend V0.90 has been released. It is available in the CVS and on my
<BR>
homepage.
<BR>
Changes:
<BR>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- fix timing problem between killing child and writing to pipe
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- change fprintf(stderr,...) to DBG
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- change include &lt;sane..&gt; to &quot;sane..&quot; in hp.h
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- change handling of options that have global effects.
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.e. if option scanmode is received (has global effect),
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;all options that &quot;may change&quot; are send to the scanner again.
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This fixes a problem that --resolution specified infront of
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--mode on command line of scanimage was ignored.
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOTE: This change does not allow to specify --depth 12 infront
<BR>
of
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;--mode color, because --depth is only enabled with --mode color.
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- add depth greater 8 bits for mode grayscale
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- add option for 8 bit output but 10/12 bit scanning internally
<BR>
<P>--Peter
<BR>
<P><PRE>
