Hi all,
I am quite new to ChicagoBoss and I am struggling to just add a simple
function to an existing model module.
My module is image.erl.
I have a function called create_processed_file():
create_processed_file(FileType, Size) ->
lager:info("-=> Stepping into create_processed_file <=-"),
OriginalFilename = THIS:get_filename(FileType, Size),
GammaValue = THIS:gamma(),
NewFilename = THIS:apply_gamma_factor(OriginalFilename, GammaValue),
NewFilename.
I added THIS:apply_gamma_factor/2.
The function is defined at the end of the file:
apply_gamma_factor(Filename, Gamma) ->
lager:info("-=> GAMMA PROCESSING : ~p", [Gamma]),
ProcessedFilenamePart = "_gamma_" ++ io_lib:format("~4.2f", [Gamma]),
NewFilename = "/tmp/" ++ filename:rootname(filename:basename(Filename)) ++
ProcessedFilenamePart ++ filename:extension(Filename),
case (Gamma == 1.0) of
true ->
% if gamma == 1.0 let's just copy the original image with the new file
name.
lager:info("[apply_gamma_factor] - gamma = 1 - copying ~s to ~s . ",
[Filename, NewFilename]),
{ok, _} = file:copy(Filename, NewFilename);
false ->
% if gamma /= 1.0 then we need to create the processed image.
case filelib:is_regular(NewFilename) of
false -> %% send to graphicsmagick for processing
GammaCmd = io_lib:format("gm convert -gamma ~f ~s ~s ",
[Gamma,
Filename,
NewFilename]),
os:cmd(GammaCmd);
true ->
undefined
end
end,
NewFilename.
I cleaned, built and restarted my CB application and every time I get the
same error:
*13:08:34.929 [info] -=> Stepping into create_processed_file
<=-13:08:34.946 [error] gen_server gsd_report_server terminated with

line 196 in gen_server:terminate/7 line 804*
So it enters the create_processed_file function but somehow cannot 'see'
the apply_gamma_factor/2 fuc, instead it looks for a function with more
parameters.
Could you please help me in solving this problem?
Thanks in advance
