c# - Convert bitmaps to one multipage TIFF image in .NET 2.0 -

-

how can convert array of bitmaps brand new image of tiff format, adding bitmaps frames in new tiff image?

using .net 2.0.

start first bitmap putting image object

bitmap bitmap = (bitmap)image.fromfile(file);

save bitmap memory tiff

memorystream bytestream = new memorystream(); bitmap.save(bytestream, imageformat.tiff);

put tiff image object

image tiff = image.fromstream(bytestream)

prepare encoders:

imagecodecinfo encoderinfo = getencoderinfo("image/tiff");  encoderparameters encoderparams = new encoderparameters(2); encoderparameter parameter = new encoderparameter(     encoder.compression, (long)encodervalue.compressionccitt4); encoderparams.param[0] = parameter; parameter = new encoderparameter(encoder.saveflag,      (long)encodervalue.multiframe); encoderparams.param[1] = parameter;

save file:

tiff.save(soutfilepath, encoderinfo, encoderparams);

for subsequent pages, prepare encoders:

encoderparameters encoderparams = new encoderparameters(2); encoderparameter saveencodeparam = new encoderparameter(      encoder.saveflag,       (long)encodervalue.framedimensionpage); encoderparameter compressionencodeparam = new encoderparameter(      encoder.compression, (long)encodervalue.compressionccitt4); encoderparams.param[0] = compressionencodeparam; encoderparams.param[1] = saveencodeparam; tiff.saveadd(/* next image tiff - same above memory */, encoderparams);

finally flush file:

encoderparameter saveencodeparam = new encoderparameter(      encoder.saveflag, (long)encodervalue.flush); encoderparams = new encoderparameters(1); encoderparams.param[0] = saveencodeparam; tiff.saveadd(encoderparams);

that should started.

linux - Using a Cron Job to check if my mod_wsgi / apache server is running and restart -

my group , running server based upon django , uses mod_wsgi run apache server. not working on project after over, attempting set cronjob similar functionality check if apache server has shut down(system restart or power failure), , if has, restart server me. i've found documentation on how check if apache server down , restart server if is, our server uses https , our start command pretty verbose. can use functionality provided in these examples: https://askubuntu.com/questions/277389/cron-job-to-restart-apache https://www.digitalocean.com/community/tutorials/how-to-use-a-simple-bash-script-to-restart-server-programs or need more complicated process make happen? the command use start server is python manage.py runmodwsgi --host 0.0.0.0 --port 8001 --https-port 8000 --ssl-certificate (certificate location) --server-name (domain name) i'm pretty new linux , using both mod-wsgi apache appreciated. you better off using --setup-only option mod_wsgi-expres

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
