Project Py-Meme

Project Py-Meme

I decided to have a crack at a brand new project, a meme creator with, of course, a Shambles GUI.

A meme is just a funny image, with some amusing text on it, like this example:

There is nothing new about this of course, memes have been doing the rounds since the early 1990s, hey I’m catching up!

I got started writing the code with the slimmest of plans, do I ever learn from my past mistakes?  Yes and no, I know I will get in trouble as soon as the project gets complicated and as I realise what features need to be added I will regret not planning for it.  See virtually any of my previous projects on this blog for an example.

But, just going for it with great enthusiasm is just how I do things, it’s how my brain works, I cannot see past the initial concept, no matter how hard I try, and I have tried.

One thing I found when planning too much and trying to pre-empt problems and what future features to add actually scares me off as I have very low coding skill and confidence.

Enough crying already.  Project Py-Meme.

• create GUI frame
• Load and display  image
• User inputs text on image
• save image.

At the time of writing I have achieved the above four elements and it works.  I wouldn’t say I am happy with it, as it needs a lot of work to make it more useful, user friendly and flexible.

There are many problems with this project, most of which I can’t seem to get past as yet.

• Some images won’t load or load and crash when try to put text on.
• I can’t work out yet how to undo the users text, if required.
• How do I know weather to use black or white text on the background, maybe give the user the option to change text colour?
• I haven’t looked into fonts yet but font and font size should be offered I guess.  But this will open up a small can of worms on text width etc.
• Baring in mind that the text is converted to an image before being placed on the background (not my doing, it’s the only way to get it centred) how can I allow for multiple lines of text if the user requires it.

At the moment I am at a quite low ebb after all the Xmas shenanigans that goes on.  I don’t feel particularly good, and the Pyinstaller false positive virus problem is just depressing me to the point that I started looking at other programming languages.

After reading the first chapter on a beginners guide to Ruby I quickly came back to Python knowing that this is the best I can ever hope for.  Don’t get me wrong, I love Python and appreciate all the hard work that goes on behind the scenes by volunteers and that it is free, I just get very frustrated that I don’t really understand how to use it properly yet.

Sob. If only Amos Basic was ported properly to the PC, I could of died a happy man.

Anyway, here is my crap Python code, it works sometimes.  It can act as a reminder on how not to code I guess.
