'PAIN' super-verbose help page
Programmed by LDDestroier
(use UP/DOWN or scrollwheel, exit with Q)
If you wish to use PAIN to its fullest, read everything here.
You'll be image-editing like a pro in no time flat.
Syntax:
>pain <filename> [view] [x] [y]
>pain [-n]
>pain [-h/--help]
[view]: renders the image once (optionally scrolling with [x] and [y])
"-n" or no arguments: Create new document, declare name upon saving
"-h" or "--help": Display short syntax help
You can see what colors are selected based on the word "PAIN" on the hotbar.
Hotkeys:
left/right ctrl: Toggle the menu
left click:
+left shift = Drag and let go to draw a line
-alone = Place a dot
Right Click: delete pixel
Middle Click, or "T": Place text down with current colors; cancel with X
"Z":
+LeftAlt = Redo
-alone = Undo
"P": Pick colors from position onscreen; cancel with X
"N":
+LeftShift = Change character to that of a special character
-alone = Change box character for drawing
(cancel with CTRL, N, or by clicking outside)
"[" or mouse scroll down:
+LeftShift = Change to previous text color
-alone = Change to previous background color
"]" or mouse scroll up:
+LeftShift = Change to next text color
-alone = Change to next background color
"F1":
-alone = Access help screen
"F3:"
-alone = View all connected monitors
Spacebar:
+LeftShift = Toggle background grid
-alone = Toggle bar visibility
Arrow keys:
+LeftShift = Displaces the entire frame
+Tab = Moves canvas one pixel at a time
-alone = Looks around the canvas smoothly
"+" (or equals):
+LeftAlt = Swap the current frame with the next frame
+LeftShift = Merge the current frame atop the next frame
+RightShift = If you are making a new frame, duplicates the last frame
-alone = Change to next frame
"-":
+LeftAlt = Swap the current frame with the previous frame
+LeftShift = Merge the current frame atop the previous frame
-alone = Change to previous frame
(oh good, you're actually reading this stuff)
"A": Set the coordinates to 0,0
"N": Open block character selection
"B": Toggle redirect to blittle, to preview in teletext characters
"c":
+LeftAlt = Select region to copy to specified clipboard
-alone = Input coordinates to scroll over to
"LeftAlt + X": Select region to cut to specified clipboard
"LeftAlt + X": Pastes from specified clipboard
"G": toggle grayscale mode.
Everything is in shades of gray.
If you Save, it saves in grayscale.
"F":
+LeftShift = fill all empty pixels with background color and selected box character
-alone = activate fill tool - click anywhere to fill with color
"M": set metadata for pixels (for game makers, otherwise please ignore)
==================================
Thy Menu (accessible with CTRL):
==================================
Left click on a menu item to select it.
If you click on the menubar, release on an option to select it.
"File > Save"
Saves all frames to a specially formatted PAIN paint file. The format PAIN uses is very inefficient despite my best efforts, so Export if you don't use text or multiple frame.
"File > Save As"
Same as "File > Save", but you change the filename.
"File > Export"
Exports current frame to NFP, NFT, BLT, or the horribly inefficient PAIN format.
"File > Open"
Opens up a file picker for you to change the image currently being edited.
"Edit > Delete Frame"
Deletes the current frame. Tells you off if you try to delete the only frame.
"Edit > Clear"
Deletes all pixels on the current frame.
"Edit > Crop Frame"
Deletes all pixels that are outside of the screen.
"Edit > Change Box Character"
Opens the block character selection. Used for making those delicious subpixel pictures.
"Edit > Change Special Character"
Opens the special character selector, which lets you change the paint character to that of byte 0 to 255.
"Edit > BLittle Shrink"
Shrinks the current frame using the BLittle API. Very lossy, and unreversable without Undo.
"Edit > Copy"
Drag to select a region of the screen, and save it in a clipboard of a specified name.
"Edit > Cut"
Same as Copy, but deletes the selected region on the screen.
"Edit > Paste"
Takes the contents of the specified clipboard, and plops it on the canvas where the mouse is.
(The mouse will indicate the top-left corner of the pasted selection)
"Set > ..."
Each option will toggle a config option (or set it's value to something else).
Changing a value is saved automatically, and effective immediately.
"Window > Set Screen Size"
Sets the sizes of the screen border references displayed on the canvas.
"Window > Set Grid Colors"
Sets the backdrop colors to your currently selected color configuration.
"About > PAIN"
Tells you about PAIN and its developer.
"About > File Formats"
Tells you the ins and outs of the file formats, and a brief description of their creators.
"About > Help"
Opens up this help page.
"Exit"
Durr I dunno, I think it exits.
I hope my PAIN causes you joy.

x1 and y1: top-left corner coordinates of menu window. defaults to the top-left corner of the screen
x2 and y2: bottom-right corner coordinates of menu window. defaults to the bottom-right corner of the screen
_path: path to start viewing. defaults to "/"
_noFiles: whether or not to view files in the menu, mainly for picking a path for installing something. defaults to false
_noFolders: whether or not to view folders in the menu, mainly for choosing a file to run or whatever. defaults to false
_noCD: whether or not you can change the directory, mainly to limit choices to a single folder. defaults to false
_noSelectFolders: whether or not you can select folders to return. defaults to false
_doHidden: whether or not to hide hidden files (starts with "."). defaults to false
_p: the palate. has: bg, d_txt, d_bg, f_txt, t_bg, p_txt, p_bg, scr, scrbar. 'd' is for directory, 'f' is for file, 'p' is for path bar.
_canClose: whether or not you can click on the little top-right "Cancel" button.

Advanced Paint Program
by LDDestroier
or EldidiStroyrr
if you please!
PAIN is a multi-frame paint program with the intention of becoming a stable, well-used, and mondo-useful CC drawing utility.
The main focus during development is to add more functions that you might see in MSPAINT such as lines or a proper fill tool (which I don't have, grr hiss boo), as well as to export/import to and from as many image formats as possible.
My ultimate goal is to have PAIN be the default paint program for most every operating system on the forums. In order to do this, I'll need to make sure that PAIN is stable, easy to use, and can be easily limited by an OS to work with more menial tasks like making a single icon or what have you.

local aboutFileFormats = function()
local helpText = [[
Here's info on the file formats.
"NFP":
Used in rom/programs/paint, and the format for paintutils. It's a handy format, but the default rendering function is inefficient as hell, and it does not store text data, only background.
Cannot save multiple frames.
"NFT":
Used in npaintpro and most everything else, it's my favorite of the file formats because it does what NFP does, but allows for text in the pictures. Useful for storing screenshots or small icons where an added level of detail is handy. Created by nitrogenfingers, thank him.
Cannot save multiple frames.
"BLT":
Used exclusively with Bomb Bloke's BLittle API, and as such is handy with making pictures with block characters. Just keep in mind that those 2*3 grid squares in PAIN represent individual characters in BLT.
BLT can save multiple frames!
"PAIN Native":
The basic, tabular, and wholly inefficient format that PAIN uses. Useful for doing math within the program, not so much for long term file storage. It stores text, but just use NFT if you don't need multiple frames.
Obviously, this can save multiple frames.
"GIF":
The API was made by Bomb Bloke, huge thanks for that, but GIF is a universal file format used in real paint programs. Very useful for converting files on your computer to something like NFP, but doesn't store text. Be careful when opening up big GIF files, they can take a long time to load.
Being GIF, this saves multiple frames!
"UCG":
Stands for Universal Compressed Graphics. This format was made by ardera, and uses Huffman Code and run-length encoding in order to reduce file sizes tremendously. However, it only saves backgrounds and not text data.
Cannot save multiple frames.
I recommend using NFT if you don't need multiple frames, NFP if you don't need text, UCG if the picture is really big, Native PAIN if you need both text and multiframe support, and GIF if you want to use something like MS Paint or Pinta or GIMP or whatever.
