so about image processing. sure I know that tgere is gxml but I dont have any samples or documentation how to edit some image and show it to user in web browser there is some stuff I done by my self. this is maximum I can figure out in attachments you can see what I have done and there it is on web http://katalogs.core.lv/demo peace of script. this section will build thumbnails from images in selected folder (on the web page you can see) buff = Stdio.read_bytes("/box1/demo/"+id->variables->cat+"/"+id->variables->img); if (buff != 0 ) { object OurImage; OurImage = Image.JPEG.decode(buff); float xsize = (float) OurImage->xsize(); float ysize = (float) OurImage->ysize(); float scale = 1.0; if (xsize > ysize) scale = ((float) 90)/xsize; else scale = ((float) 70)/ysize; OurImage = OurImage->scale(scale); reply = Image.JPEG.encode(OurImage); array dir = get_dir("/box1/boss/demothumbs/"+id->variables->cat+"/"); if (arrayp(dir)==0) { mkdir("/box1/boss/demothumbs/"+id->variables->cat+"/"); } open_res = me->open("/box1/boss/demothumbs/"+id->variables->cat+"/" + id->variables->img,"cw"); if (open_res == 1) me->write(reply); me->close(); } else { open_res = me->open("/box2/fotodata/default/not_found.gif","r"); reply = me->read(); me->close(); } so there I made decode and encode jpg image and image resizing so I wan to add there more image pike options like sharpen blur colorize lighten darken and more (or also draw some ither image transparent gif as logo ) of course these options will be seperated by if conditions it would give ability to proccess images on the fly and add some effects on the web site you can see some samples I have done with cimg and gtext but I dont like this pike is faster and more options more actualy I wan to create a web site where users can pick some image put some nice text on it some masks effects borders . in one word . add on image some stilistic stuff and in result will get very nice personalised postcard .. also it is important for web site creation dinamicaly draw texts effects and more on images

get_url_data
by Peter Bortas ＠ Pike developers forum 28 Sep '02

28 Sep '02

Protocols.HTTP.get_url_data and Protocols.HTTP.get_url_nice are in my opinion flawed. According to the docs "0 is returned upon failure". That failure will have to be pretty severe though. It will return data as long as the server responds properly. Error codes are ignored. They would gain usefullness if at least the 4xx and 5xx series of errors are considered "failures". Unless the 1xx and 3xx-series are handle somewhere they should also return 0. I'll fix the code if noone protests.

Time for another test release of the client. Download http://peter.bortas.org/xenoclient-1.0-test3.tar.gz and see if it works for you and if you have any problems following the README. Report back here.

Gz testsuite memory usage
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 27 Sep '02

Since many of the structures are allocated via block_alloc.h, it would probably be a good idea to let block_alloc.h:really_free_DATA() be able to free entire blocks too.

Hi! Can you tell me where can I search for pike features? Especially I cannot find the "basic" "string matches regexp" and "replace regexp in string" functions? thx Gergő +-[Kontra, Gergely @ Budapest University of Technology and Economics]-+ | Email: kgergely(a)mcl.hu, kgergely(a)turul.eet.bme.hu | | URL: turul.eet.bme.hu/~kgergely Mobile: (+36 20) 356 9656 | +-------"Olyan langesz vagyok, hogy poroltoval kellene jarnom!"-------+ .

An advance notice on possible CVS breakage
by Johan Sundstr�m (nu �ven i Gottfridsberg!) ＠ Pike (-) developers forum 26 Sep '02

26 Sep '02

If anyone would notice something strange when committing or tagging things in the Pike CVS (or other repositories hosted on the server), I would appreciate a copy of the output here or in my personal mailbox. Hopefully no problems will occur, but just in case, I thought I'd give some notice, so you don't mutter about breakage non-publicly. For the curious, the code librarian will start indexing the CVS repository by commitinfo and taginfo triggers rather than a cron job, which should hopefully boost performance noticably. The change will take place sometime tomorrow, probably in the morning. (It felt best not to do system maintenance just before going home. :-)

Hang on NT
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 25 Sep '02

25 Sep '02

I've come across a problem with a pike 7.2 lockup on NT (or at least I think it's NT related): A pike process has some threads (seven, to be exact), where some wait on Thread.Queue conditions and one is waiting in a blocking read from a socket. The main thread is running in the normal backend. After a while everything locks up when one thread puts an item in a Thread.Queue and the corresponding reading thread simply doesn't get started. In this state the process seems to be completely locked up, at least a SIGBREAK won't cause a call to the installed signal handler. The only way to get it started again is to close the socket from the other side (at which point the SIGBREAK handler will also get started with the queued up signal). What is at work in the lower layers here? Is there some internal mediating thread that's been locked? Does anyone remember if some fix that's only gone into 7.3 possibly could address this?
