The entire code base has been cleaned (with the help of these + CodeRush and Refactor!), the whole design is being improved, and lots of little bugs have been fixed. It’s already massively different and far more readable then before. I’m keeping the change log up to date with the code in the SVN CVS: http://ascgendotnet.jmsoftware.co.uk/changelog

The next release will be Ascgen dotNet version 2.0.0 (or to make things easier, Ascgen 2.0). I don’t know when it will be ready, it just depends on whether I want to release something functionally almost identical to the current version, or if I go forward with some new features.

The main new thing I want to add is a new method of conversion which will be available in addition to the current ones. It’s for fixed width fonts only, and gives a much better output for line art style images.

Also, I don’t know if I’ll keep up with this, but: http://twitter.com/ascgen

I was waiting until I’d finished rewriting one of the controls, but I just had a pretty huge crash bug pointed out to me.

Added a form to preview the colour output
Added menu item to change the position of the image and text frames from horizontal to vertical
Added automatically choosing the panels orientation layout from the screen size
Changed main form to access the RichTextBox through an interface
Moved interfaces into their own namespace
Fixed being unable to save variable width font conversions as an image

If you do see something obviously wrong, please report it on the sourceforge page (“Help/Report a bug…”). You don’t have to have an account there and you can do it anonymously.

Internal design changes, and some cool new stuff.

Dithering
Thanks to an great idea sent to me through sourceforge, the program now comes with the ability to run a dithering filter over the output.

Why would you want this? Well, the text output is like having an image with a small palette of colours. Adding noise to the output helps to blend the different greyscale colours together and produces a result that is (hopefully) more pleasing the eye. There’s also a random element which weights the dithering and helps hide the pattern.

Check out the wikipedia article for more information on the theory behind this topic.

Translation file changes
The program will now automatically load a translation file if one (and only one) is in the same directory as the executable. The filename has to be in the format translation.*.xml with * being the language code (although at the moment it doesn’t matter what you put there). For an example, here’s the American translation file: translation.en-us.xml

The full list of untranslated strings is here:
http://ascgen2.cvs.sourceforge.net/*checkout*/ascgen2/ascgen2/translation.xml

Text Widget
The brightness/contrast and levels widgets have been merged into one new widget, using tabs to switch between them and a new control for adjusting the dithering levels.

Visual Studio 2008
The codebase has been moved to the new Visual C# 2008 Express Edition, so you’ll need that if you want to compile the source code yourself. The executable is still being targeted at .Net 2.0 so hopefully there shouldn’t be any difference (I can’t see any good reason to change it to the latest .Net yet).

Full change log:
Fixed extra characters being added to colour rtf files in some font sizes
Added automatic loading of a translation file (translation.?.xml) if one is present
Added a basic dithering filter to the output
Changed Ascii filters to implement an interface rather then inheriting a class
Added specialized interfaces for the filters
Moved brightness/contrast and levels into one widget
Improved the levels control
Stopped brightness/contrast accepting clicks from anything other than the left mouse button
Stopped brightness/contrast control updating the output twice on reset or image load
Added new control for dithering level and dithering random level to the text widget
Added loading and saving the dithering values to the settings file
Changed text widget to implement the brightness-contrast/levels/dither interfaces
Changed brightness-contrast widget to implement the brightness-contrast interfaces
Made main form access the widgets through their interfaces rather then directly
Moved code development to Visual Studio 2008
Fixed processing the conversion twice during image load

1) The way the output is displayed using characters gives the effect that the colours look lighter then they should. Adjust the image brightness and contrast to make the input darker and have the colours stand out more, or with inverted (i.e. white text on black) output make it lighter. Hopefully I’ll come up with a way to compensate for this automatically.

2) I think that having the colour output with the text inverted looks much better then with the normal white background.

3) Try removing the space and punctuation from the valid characters for the ramp (”Edit/Ramps/Valid Characters…”).

I might try to do a tutorial for colour output.

Localization
Here’s an example translation file to localize the program into American English. Save it to the same directory as the exe file and call it translation.xml.

Other
Some people complained, so if you don’t want the program checking for a new version each time it starts up (which just tries to grab a tiny xml file from the sourceforge page) you can now turn it off without leaving the program. Go to ‘Edit/Edit Settings…’ and uncheck the ‘New Version Check’ box, then press ‘Ok’ and go to ‘Edit/Save Settings as Default’.

I considered having it turned off as default since I added the manual version check (’Help/Check for a New Version’), but who would turn it on?

Also, please consider donating if you enjoy this program, or at least help spread the word about it. Having the external links removed from Wikipedia ASCII Art pages really hurt the traffic to this site (and the money per ad click has gone down the toilet).

Changes:
Added toolstrip with buttons to rotate and flip the input image
Replaced the different save menu items with a dialog
Set Accept (enter) and Cancel (escape) buttons for edit settings and text magnification forms
Fixed ctrl codes being enabled/disabled when they shouldn't be if the menu hasn't been opened

Translation file changes are here.

Check out the previous post for details about how to translate the program into other languages. If you do a translation, please let me know so I can add it for other people to use.

Changes:
Improved speed of applying convolution matrix (used in output filters)
Added saving to an image with colour
For images with transparency, the transparent area is now black if output was inverted on load
Changed to no longer prompt to save after saving as an image
Added colour print and print preview
Added loading resource strings from an xml file
Added translation filename to the variables and settings file
Added form to change some basic settings in the program
Improved speed of automatically generating ascii ramps
Moved updating the settings into the Variables class
Moved processing xml nodes into a new class
Added saving as a nfo file
Localized the batch conversion log
Removed depreciated Hidden property from the widgets
Moved saving the settings into the Variables class
Changed the settings file to read and write to settings.xml
Fixed Ramp dropdown box being cut off
Moved Brightness/Contrast controls into a separate control
Replaced brightness/contrast textboxes with numeric up down boxes
Added saving as colour text and images in a batch conversion
Added a menu item to check for a new version
Fixed current output directory changing back to the default directory after saving
Added right-click menu item to reset the brightness/contrast widgets

Originally I planned to use the inbuilt globalization stuff, but it’s unbelievable how complex it makes everything. Instead I’ve come up with my own easy system that piggybacks on the existing resource class and loads the strings from an external xml file.

The current full list of translation strings is here:
http://ascgen2.cvs.sourceforge.net/*checkout*/ascgen2/ascgen2/translation.xml

You can use any or all of these by translating the strings inside the tags.

It will also finally come with saving to colour image files, and printing in colour. Which was much harder then the translation stuff.

I’m not sure whether to have the version number as 0.8.3 or 0.9.0. Maybe 0.8.5?

Plus, I’ve changed http://www.jmsoftware.co.uk/ into a blog so I can start posting more off topic stuff without cluttering this one up, and I hope to start posting regularly soon. It also hosts a few random little programs.

I also made a ton of code changes to improve how things are structured.
