Bitmap loading from array - representation

[Newbies] Bitmap loading from array - representation Hi Pete, The way to a bitmap definition is easier. This is squeak. You get the picture of what you want. (Draw, paint or photograph and scan). Get it into squeak. Then you ask the forms bitmap to print itself as an array. Or Maybe even the form can print itself out. If you don't quite get what you need edit it into a definition and save/accept the definition as a message to some object. And your done. E.g. David Röthlisberger suggestion: http://mail.wiresong.ca/pipermail/ob-dev/2007-December/000259.html | image stream | image := ColorForm fromFileNamed: '/path/to/picture/icon.gif'. stream := WriteStream with: String new. image storeOn: stream. stream contents. If you get your image in another way just modify the above code to accomodate. Note with a little extra effort you could alter the above code to write an initalization routine. It takes a while to think in squeak. The trick is realizing how easy it can be to do what you want. Hth, Yours in service and curiosity, --Jerome Peace ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

Catching runaway process
by stan414 06 Dec '07

06 Dec '07

Hi, I probably should introduce myself before hitting you with some new questions. I've been developing a website with games written in Java, and decided that it was too slow to develop each new game, hence the interest in Squeak. As I live on a French Alp, I have plenty of time for coding during the off season. My current project to teach myself Squeak is an experiment with genetic/evolution algorithm. Because of the randomness, I need to be able to catch antisocial processes. I thought I could do this with CPUWatcher: CPUWatcher startMonitoringPeriod: 20 rate: 100 threshold: 0.3 or by starting with the defaults in ProcessBrowser. !Darwin methodsFor: 'as yet unclassified' stamp: 'ss 12/6/2007 18:21'! intentionalRunaway self intentionalRunaway! ! [Darwin new intentionalRunaway] forkAt: 30 named: 'runaway' or just Darwin new intentionalRunaway I expected this to be caught by catchThePig, but it doesn't appear to find it. My O/S is Ubuntu 7.10, and the result was the same under Windows XP SP/2. Have I misunderstood the function of ProcessBrowser/CPUWatcher/catchThePig?

Bitmap loading from array - representation
by Pete 06 Dec '07

06 Dec '07

Hi, I'm new to Smalltalk, coming from C++ and Java. I find Squeak very interesting, especially the features for rapid prototyping. I tried learning on the job, started with the Games-Chess class category, as I'm was formerly experienced in chess programming. My problem is that I dont understand how Bitmaps for Forms are defined: blackKingImage ^((Color yxForm extent: 40@40 depth: 2 fromArray: #( 0 0 0 0 0 0 0 0 0 0 4194304 0 0 22020096 0 0 4194304 0 0 89391104 0 0 111411200 0 1398016 107216981 1426063360 22369600 107218261 1430257664 22456660 107222362 2772434944 89740885 111416741 1498415104 90527125 1162892885 1448083456 93672805 1095850325 1448083456 362108249 1431656790 2522087424 362190169 1435854230 2522087424 362190422 1452643686 2522087424 362112598 1431672169 1448345600 362112597 2505463146 2522087424 93760085 2505463145 1448083456 93678165 2526434665 1448083456 93673045 1704351141 1498415104 90527317 1700353429 1498415104 23418261 1700353429 1497366528 22631829 1499027029 1497366528 22631829 1503221333 1698693120 5657957 1503222101 1694498816 1463653 1499026773 2483027968 1414485 1499026774 1409286144 354986 2841291433 1342177280 87381 1431655765 1073741824 21845 1431655765 0 5802 2863311508 0 6485 1431655780 0 6485 1521046884 0 6485 1431655780 0 6826 2863311524 0 5461 1431655764 0 0 0 0 0 0 0) offset: 0@0) colorsFromArray: #(#( ) #(0.0 0.0 0.032) #(1.0 1.0 1.0) #( ) )) I searched the whole Web for an explanation, but found none. It's also not clear to me why this array is size of 120, when we have an rectangular region of 40x40, and what is the difference of depth 1,2,4 ... To create my own chess fonts I should detailed know how this array/bitmap definitions are interpreted by Squeak ! Thanks in advance ! Pete __________________________________ Ihr erstes Fernweh?

serving alternate image with Ubuntu LTSP
by sam 04 Dec '07

04 Dec '07

I am trying to serve (Ubuntu server) squeak to a lab of thin client machines. After installing squeak on server I can. * See and run squeak from Applications->Education on Server * See and run squeak from Applications->Education on Client I really need to use the eToys image though so placed it on the server in the same directory as indicated on the "Please choose a (sic) Image File" dialog --- "home/****/squeak". Having done this I can: * See and select the eToys image on the Server * NOT see the eToys image on the client. At the moment I have to copy and paste the image into each client's home/user/squeak in order to run it. This of course is not the end of the world but it means that every time I have new projects for the kids in the class, I have to copy them to the local accounts rather that serve them ... Any ideas? Thanks, Sam
