Plotting Images
by Pei-Yu CHAO July 31, 2007

July 31, 2007

Hi ALL: I have only been switched from matlab to python few months ago. I having trouble of plotting images from a matrix size of 8x10000 (unfortunately that is the size of my data.....) for example, x = rand(8,10000) inshow(x) I have tried to use matplotlib function imshow(), but all i get is a long thin line (unable to see the color display and the my matrix information). i think imshow() has the same problem in matlab, but i think there is a alternative in matlab, imagesc(). I did search on web about plt.imagesc().....but when i try to run the example code, python just tell me cannot find module plt. >>>from scipy import plt ImportError: cannot import name plt I have installed scipy, wxpython2.6....and it still seem not to work! is there some alternitive? or what have i done wrong? Thank you Pei ____________________________________________________________________________________ 想及時通知通訊錄裡的所有親朋好友好消息，就來 Yahoo!奇摩電子信箱發簡訊！ http://tw.mobile.yahoo.com/texts/mail.php

It is very interesting, but is not what I need. I am looking for something that can provide service to web pages. For example, when a browser requests a web page, the web page is going to send a few requests to my server. My server then is going to respond, and the web page takes the response and format it in human readable form.

For a more narrative approach to the same point, I like to think that <URL: http://www.unixreview.com/documents/s=10133/ur0706e/ > helps.

Hi, If I have a number n and want to generate a list based on like the following: def f(n): l=[] while n>0: l.append(n%26) n /=26 return l I am wondering what is the 'functional' way to do the same. Thanks, beginner

Compiling 2.5.1 on OpenBSD 4.1
by nazgul July 31, 2007

July 31, 2007

Hi all, In my prev post, I indicated I was using 2.5.1 on one box and 2.5p3 on the OpenBSD box. I'm trying to build 2.5.1 on OpenBSD and I get this: Modules/posixmodule.c:5701: error: `lstat' undeclared (first use in this function) I browsed the source and don't understand why I'm getting it. I'm not a configure expert, but I did figure out that pyconfig.h has these set: #define HAVE_LSTAT 1 #define HAVE_SYS_STAT_H 1 #define HAVE_SYS_TYPES_H 1 and that posixmodule.c includes sys/stat.h, sys/types.h (per the lstat manpage) as well as declaring lstat outright. I'm stumped. Any suggestions? ./configure was run with no options. TIA, nazgul

If it's scaled down so that the largest dimension is 1000px, then the smaller dimension will be reduced to 1px. Try breaking your image into various "strips".
