I've just found out that the following variables on index.php seem to be causing the issue:
$M_WIDTH=Get_Values('loc_maxW'); $M_HEIGHT=Get_Values('loc_maxH');
They are set to '', so Get_Values function cannot retrieve loc_maxW and neither loc_maxH.
I've manually set them to the maximum width and height, but this makes it impossible to resize once again after first resize.
this is my output, same settings as screenshot
www-data@127.0.0.1:/home/www-data/php-scanner$ scanimage -d 'hpaio:/usb/Deskjet_F4400_series?serial=CN05DC61TP05C5' --source 'Flatbed' -l 0 -t 0 -x 201.98644444444 -y 279.4 --resolution 75 --mode 'Color' --format=pnm > '/tmp/scandir0/scan_file0.pnm'
The output of this command unfortunately has to be suppressed to prevent errors :(
Run `sudo -u www-data scanimage -d 'hpaio:/usb/Deskjet_F4400_series?serial=CN05DC61TP05C5' --source 'Flatbed' -l 0 -t 0 -x 201.98644444444 -y 279.4 --resolution 75 --mode 'Color' --format=pnm > '/tmp/scandir0/scan_file0.pnm'` for output info

I have encountered a scanner that reports it size wrong so if you were to manually tell it to run a full scan it fails to scan cause it is out of bounds, i would have to guess there is a issue which some code i don't recall writing to compensate for that but what does not make sense is the 1st attempt to scan used a 0,0,0,0 setting
can you post your scanners help data you can get that info from this page by clicking the device string http://10.0.1.15/scanner/index.php?page=Device%20Notes
Hi @GM-Script-Writer-62850, thanks a lot for your reply, sorry to let you waiting this long. The image you requested:
The 0,0,0,0 setting comes from the fact that M_WIDTH and M_HEIGHT are empty. When it does this calculations:
$WIDTH=$WIDTH/$M_WIDTH*$TRUE_W;
$HEIGHT=$HEIGHT/$M_HEIGHT*$TRUE_H;
$X=$X_1/$M_WIDTH*$TRUE_W;
$Y=$Y_1/$M_HEIGHT*$TRUE_H;
$SIZE_X=$WIDTH;
$SIZE_Y=$HEIGHT;
around line 1200, as they are unset, all values are set to 0.
Thanks for your help. :)
i need the terminal output shown when you click on the device string (2ed bullet point)
this file would also help: /var/www/scanner/config/scanners.json
(not necessary if i have the other)
The content from scanners.json:
pi@raspberrypi:/var/www/scanner $ cat /var/www/scanner/config/scanners.json && echo

Odd, seems to work here, at least generating the command to scan which is where the issue is manifesting for you i did find a error while i was checking for this issue (unrelated though)
maybe something very strange is happening, lets pop a debug message in here
debugMsg("W='$WIDTH',H='$HEIGHT',MW='$M_WIDTH'");
that is right after line 1185 in index.php
this SHOULD print a message of W='427',H='471',MW='450'
when you run a scan with the settings from your screenshot
you can pop another one after line 1238 in index.php
the second message should print W='204.86511111111',H='279.4',MW='450'
I have followed your instructions. First I've reset the index.php to the head used on the github (I didn't reset all the package otherwise I would have to reconfigure the scanner, and I wanted to avoid this if possible).
After, I've added the debug messages on the places you requested. What follows are the images of the debug messages without selecting any region:
After selecting a region:
and the browser inspected parameters:
It seems that the browser, for some reason, is not passing the right loc_maxW and loc_maxH comparing to your sample.
I'll wait for more instruction as I don't know what could be the cause of this (I don't know any web language and how the browsers communicate).
those values come from the rendered size of the preview image, they are set when you click the scan button during right before it lets the page submit https://github.com/GM-Script-Writer-62850/PHP-Scanner-Server/blob/master/res/main.js#L110-L111 maybe there is a bug in the mac firefox? tried chrome or safari?
I've attempted in the two remaining browsers. It worked only on the chrome… really funny bug.
Safari:
Chrome:
Thanks a lot for helping me track this issue.
in firefox open the error console (CTRL+SHIFT+K) do you get a error when clicking submit in firefox?
It says: unreachable code after return statement main.js:742:1
, but it is a warning. I've added all verbosity that I could and took a screenshot.
Hi there,
I'm very happy to have found this git package. I've installed it on my Rpi 2, and it is successfully working when I try to scan a file. A sample log file when I don't select any region is as follows:
But, if I select a region, it then fails to retrieve the region configuration:
As it can be seen on the log, it uses a region of 0,0,0,0, although it was selected a region of 0,0,421,471 as can be seen in the image.
Any hint of what might be causing this?
