Convert hexadecimal characters to ascii
Hi, I've got this weird problem where in some strings, parts of the string are in hexadecimal, or thats what I think they are. I'm not exactly sure...I get something like this: 's\x08 \x08Test!' from parsing a log file. From what I found on the internet, x08 is the backspace character but I'm still not sure. Anyway, I need to clean up this string to get rid of any hexadecimal characters so that it just looks like 'Test!'. Are there any functions to do this? Thanks =) -- http://mail.python.org/mailman/listinfo/python-list
Re: Convert hexadecimal characters to ascii
Wow, I didn't expect so many responses! Thanks! I will have to try out all those solutions when I have access to my computer.. What I meant was that when the string was printed onto a text file, it showed lots of boxes that are usually associated with unknown characters...When I tried to work out what the boxes were caused by, I found that there were random characters in my text...So basically, I need the text to just be clean of anything silly looking and for some reason printing to a file doesn't remove the characters which really messed up the output. This is an example of what I get: http://durand.zephyrhosting.net/tremcs/ Look at the top of the page under "Stats for..." The really weird thing is that it only happens with some strings and I have no idea how to predict which ones. Thanks again! I will let you know of the outcomes. -- http://mail.python.org/mailman/listinfo/python-list
PIL: Transparent PNGs and im.paste: ValueError: bad transparency mask
Hi! I'm trying to paste a png with a transparent layer into an image using "image.paste(tesla,(20,10), tesla)" but I'm getting this error: ValueError: bad transparency mask I have used im.paste(image,box,image) sucessfully before to paste an image with transparency, however, it doesn't seem to work for this particular image. How would I change the image so that it doesn't give me this error? The image is http://img293.imageshack.us/img293/1434/teslahv5.png Thanks in advance! -- http://mail.python.org/mailman/listinfo/python-list
Re: PIL: Transparent PNGs and im.paste: ValueError: bad transparency mask
I posted this too soon. Converting the images to png with image magick's convert did the trick...However, I'm still not sure why I need to convert the images in the first place. Are there different types of PNGs? -- http://mail.python.org/mailman/listinfo/python-list
matplotlib: Plotting a graph against time
Hi, I'm trying to plot a simple graph against date or time using matplotlib. I've read about date_plot but I'm not really sure how to use it. At the moment, I have some data arranged into lists, where list1 contains x values (time) and list2 contains y values just like is needed for the normal plot function. The time values are simply the output of datetime.date.today(), etc which I don't mind changing the format of. My question is, how do I plot the graph with list1 on the x axis and list2 on the y axis. Using plot and unixtime I get a very ugly scale as is to be expected so I want to know how to use the date_plot function efficiently. At the moment, I'm only concerned about the actual plotting but help with Locater Ticks (Months and Years) is also very appreciated. Thanks a lot! -- http://mail.python.org/mailman/listinfo/python-list

If I have a list of dates like ['2008-07-18 14:36:53.494013', '2008-07-20 14:37:01.508990', '2008-07-28 14:49:26.183256'], how would I convert it to a format that pylab can understand? When I tried type(datetime.now()) it gave me datetime.datetime whereas the objects in this list are strings...Am I doing something wrong here? -- http://mail.python.org/mailman/listinfo/python-list
[PIL] quake like multicoloured text
I'm wondering how I could render text with PIL in which different parts of the text are different characters. This is for a game stats script where names are written like: ^1Red ^2Green ^3Yellow, etc. The problem is that I currently use text in the ImageDraw module but the only way I can think of rendering text is by rendering each bit of text in a separate colour. Example: draw.text((0,0),"Red", fill="red") draw.text((30,0),"Green", fill="green") draw.text((60,0),"Yellow", fill="green") except that I'm not sure how much spacing there is between each coloured bit of text(30px is assumed in the example)...Would there be an alternate method of doing this? Thanks =) -- http://mail.python.org/mailman/listinfo/python-list

[matplotlib] Overlapping axis text
I got a really annoying problem with datetime graphs. The problem is
that with a long range time graph, the text on the x axis keeps
overlapping like here: http://durand.zephyrhosting.net/tremcs/graph_all.png
Would there be any way to fix this? I was thinking of rotating the
text so that there was enough space for each one but the best solution
would be to only display text with the right scale. IE, with a 7 day
graph, each day would have text, with a year long graph, each month
would be displayed, etc...
This is the code I use at the moment but its pretty messy:
import dateutil,pylab
from matplotlib.dates import MonthLocator, WeekdayLocator
fig = pylab.figure()
ax = fig.add_subplot(111)
days= MonthLocator() # every monday
months = MonthLocator() # every month
ax.xaxis.set_major_locator(months)
ax.xaxis.set_minor_locator(days)
pylab.plot_date(pylab.date2num(dates), allkills, '.-', color='blue')
pylab.plot_date(pylab.date2num(dates), alldeaths, '.-',
color='red')
pylab.plot_date(pylab.date2num(dates), kills, '.-',
color='darkgreen')
pylab.plot_date(pylab.date2num(dates), deaths, '.-',
color='orange')
if legend == 1:
pylab.legend(("Total Kills","Total Deaths", "Single
Session Kills", "Single Session Deaths"), 'lower left')
pylab.xlabel('Date')
pylab.ylabel('Stats')
ax2 = pylab.twinx()
pylab.plot_date(pylab.date2num(dates), allratio, '.-',
color='purple')
pylab.plot_date(pylab.date2num(dates), ratio, '.-',
color='yellow')
pylab.ylabel('Ratio')
ax2.yaxis.tick_right()
pylab.show()
Please excuse the extra tabbing, it's part of an if statement.

Re: Overlapping axis text
Err...made a mistake there. days= WeekdayLocator() # every monday months = MonthLocator() # every month That doesn't change my question though. Thanks -- http://mail.python.org/mailman/listinfo/python-list
