[sane-devel] Scan as PNG get "PNG support not compiled in".

[Tony]

Hi all.


From the maillist, the PNG/JPG was supported now. I want to try scan as PNG file. but I met a trouble. I can scan it well as till/PGM.


The top commit is:
commit 87bfd53512029eab9a09578376953f3907001d01
Author: m. allan noah <kitno455 at gmail.com>

    Run autofoo for recent changes


Scan command is: 
sudo scanimage --format=png > image.png
PNG support not compiled in


I tried install libpng-dev and rebuild it, but the problem has not been fixed yet. I can not find any keyword "PNG JPG" from ./configura -h.


Best regards.


Tony.
