[Printing buglet?]

The printing interface is supplied entirely by windows. This is a problem with windows.

[Not able to initialize Paint.NET]

Go to add/remove programs, find the .NET framework, and there should be a change or repair option.

[Request: Lockable Paint.NET Files]

Paint.NET is open source. It would be trivial for someone to crack the locking. Even the complicated proprietary DRM used on music, paid programs, etc. has been cracked.

[Curtis' Plugin Pack (Update for 3.5.4)]

Oooooh... Me likes... :shock:

Perhaps SharpDevelop's source code can help? (Since it's open source, you can even copy their code!)

Visual studio inside Paint.NET

[I have a New GUI idea for effects where the center is chosen]

I like it, but I don't think the part Myrddin pointed out is possible.

[Simple Drawing to Scale]

You can look at the status bar for the exact coordinates of the mouse, but you're probably better off with a vector graphics program like Inkscape.

[FolderBrowserDialog glitch]

Ok, thanks anyway.

[FolderBrowserDialog glitch]

The stream is ignored (not much else to do).

[FolderBrowserDialog glitch]

While making a plugin that saved each layer individually, I tried using a FolderBrowserDialog but it showed up blank. This only happens in Paint.NET. Any help would be appreciated.

[Easier way to save layers?]

I think this is something I could whip up in a few minutes. Stay tuned.

EDIT: Here's a really quick and dirty plugin. It saves all the layers in a folder called "Multi GIF" on your desktop.

EDIT: Removed per Rick's post.

[Default Folder in Open and Save Dialogs]

Actually it is possible to change the default folder. (through the InitialDirectory property)

[Reducing JPEG File Size]

Select all, copy, paste into a new image. (This strips out all the metadata.)

Save as JPEG and lower the quality as needed.

[Plugin Programming using Visual.Net 2005]

Yes. There's a stickied template right at the top of this forum.

[Paint.NET v3.30 Beta 2 is now available]

"View Plugin Load Errors" in the file menu doesn't seem to work for file type plugins. Because of a change in the name of the methods, my ASCII plugin broke, but the error menu item was not shown.

[Custom Brushes Plugin 5.1.5]

Yep

[Custom Brushes Plugin 5.1.5]

To do what Rick suggested, use:

[DllImport("user32.dll", CharSet = CharSet.Unicode)]

private static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, string lParam);

In the constructor:

SendMessage([name of the search textbox].Handle, 0x1501, IntPtr.Zero, "Search...");

[Another ASCII Art File Type Plugin]

It's a file type plugin.

[Another ASCII Art File Type Plugin]

I found myself in need of an ASCII art generator, but sabrown's and some online services didn't give me what I wanted. So I wrote my own.

Compiled DLL:

Put it in the FileTypes directory.

The right hand side shows the grayscale representation of the ASCII. To see the actual text, you have to complete the save and open the file with a text editor like Notepad.

The horizontal and vertical cell sizes represent the number of pixels that go into one character. Since characters are usually taller than they are wide, you should set the vertical cell size to be higher than the horizontal cell size.

[Image to texte file in hexa]

For WriteLine, wrap the stream using StreamWriter sw = new StreamWriter(output).

To convert to and from hex, invoke px.ToHexString() or uint.Parse(hex string, NumberStyles.HexNumber);

To convert to and from binary, use bitwise operations:

StreamWriter streamWriter = new StreamWriter(output);
byte r = clr.R;
for (int bit = 7; bit >= 0; bit--) {
   Console.Write(((r & (1 << bit)) == (1 << bit)) ? 1 : 0);

If you're referring the the property based effect class or the generic effect class added in 3.20, there's a property called "Token." Look at Effect`1.cs for details.

[Making this fully B and W and high quality]

Adjustments -> Brightness and Contrast with contrast set to 100 to make it black and white

Resizing and using brightness/contrast usually does a pretty good job increasing the resolution, but as David said, your best bet is vectorizing it with Inkscape (needs download) or VectorMagic (an online service).

[Increasing quality of zoomed images]

They probably use optical zoom and refocus the lenses. Optical zoom works by bending the light that reaches the camera, so the image stays sharp. Digital zoom works with pixels, so to zoom in, the computer has to create more pixels by analyzing the existing pixels. Computers cannot create extra detail that didn't already exist, so you cannot increase the quality of a digitally zoomed image with any program.

[New Feature Req. - Manage Layers Using Click and Drag]

I believe Rick meant folders by hierarchy, since by the definition of hierarchy you mentioned, you can already organize layers in a hierarchy. I'm pretty sure that this would not need the rearchitecturing planned for 4.0, since the layers are still in a linear order (i.e. not in folders).
