I'm still quite the noob with Python. I'm trying to crop a box from an image and turn it into a flat array of integers. I have succeeded in opening the image, cropping the box, and displaying both the original image and the cropped box (to check my progress). I've tried im.getdata() and...

There are API's like ImageMagic that can do everything and make you a sandwich, but all I need to do is open a graphics file and access individual pixels. What is the simplest way to do this?

Hi! It seems that this guy (IT employer, I think) went on a rant about what makes a good programmer. I figured it would make a good study guide. Can anybody direct me toward an educational resource or five that covers all of this...

What Python Standard Library modules are used most frequently?

Hi, folks! I've been searching and reading and racking my brain, but this is just eating my lunch! It's vitally important that I learn this. It seems like one of those things you easily over-think, then it comes to you in a flash of insight. I need to communicate with my Arduino...

I created an image object using GD. I am trying to use $pic->rgb($pic->getPixel($ix,$iy)) inside a function. It works fine outside of the function, but not inside the function. Is this out of scope?

Hi, folks! Over time, I've needed to change a group of numbers from this: 751,752...1087,1088 to this: 00751,00752...01087,01088 ...in other words, I've needed to change a numeric loop variable into something with a consistent number of digits. In the past, I've done this: $_ =...

Hi, Everybody! I've been using this Perl program I wrote to learn algebra rules. Really, the program could be used to learn anything, just by changing the graphics in the same folder. It might be useful to somebody. If you are interested, it's in my webspace...

Hello, everyone! I have an HP Pavilion ze4600 (ze4610us). I caught a virus off Steam - you know, the one that makes your mouse stop responding for a second, every ten seconds or so? It got into my BIOS, and I tried to reflash it with the Winflash utility on the HP site. It had been...

Hi, folks! Sean here! I'm trying to assign some defined images to an array. It keeps telling me I can't call method Photo with an undefined value. my @question; for my $q (1..20) { my $img = $mw -> Photo ( -file => "Q$q.bmp" ); push @question, $img; } What bonehead thing am I...

Hi, all! For your review, I have posted a game I wrote to improve visual memory. ( It seems that visual memory is at the root of all learning, together with emotion. ) Blue is correct placement, red is incorrect placement, and white is non-placement. As one gets better, the array should be...

Hi, folks! I've seen people reply to question with code, but the code has a box around it with the word "code" titling the box. I'm still relatively new, and I don't want to abrade other users' sensibilities here. Is there a page on this site that outlines the "whats" and "hows"; a style...

Hi, all! Is there any way to supply arguments to functions called with widgets? e.g. $button = $mw -> Button ( -command => \&do_this( this_way ) )

Hi, folks! Is it possible in Tk to reference widgets through an array? e.g. - $mywidg[1] = [button1] $mywidg[2] = [button2] $mywidg[3] = [button3] $mywidg[4] = [button4] etc...

I'm trying to remove multiple newlines from a variable using a regular expression. I've tried: $text =~ s/\n+/\n/gms; $text =~ s/\n+/\n/gs; ...but nothing works. I'm certain that there is nothing between each newline. What am I doing wrong?

I've looked through previous postings, but this exact thing doesn't seem to have come up. Given this snippet: use Win32::GUI; $box = Win32::GUI::MessageBox(undef, "Message", "Title", MB_OK); ...how do I change the text in the box as needed AFTER the box has been created? I'm needing the...

Has anybody used DLPORTIO with Perl under Win32? How does it compare with INPOUT32? It would seem more versatile.

I'm trying to dive into Python from Perl. I've found the $#var convention very useful, and I'm wondering if one can query an array to determine the number of elements. Thanks!

I have this line in my code: $mw = new MainWindow( -title=>"OSMtb Formatter",-padx=>5,-pady=>5 ); When I run the code, I get this: Can't set -padx to `5' for MainWindow=HASH(0x1a48bdc): Bad option `-padx' at C:/Perl/site/lib/Tk/Configure.pm line 46. > Terminated with exit code 255. I...

Hi, all! Is there something similar to the 'grep' function when working with hashes? e.g. - %hash = ( "abc", "a" "abd", "b" "abe", "c" "acd", "d" "ace", "e" ); somefunction ( /ab/, %hash ); => ( a, b, c )
