Is anyone else having trouble with the link ?

faubiguy, on 20 October 2012 - 01:17 AM said:

I found 2 bugs.

Attempting to floodfill an area when the area is already the color you are trying to fill it with causes stack overflow on line 744.
Also, attempting to use clear tool (x) when there is no selection causes attempt to index nil on line 642.

faubiguy, on 20 October 2012 - 07:33 PM said:

2 more bugs:

Attempting to open help for file mode causes attempt to concatenate string and nil on line 601.
Attempt to floodfill the background when there is no pixel (possibly any transparent area) causes attempt to index nil on line 1119.

hey, you should add text boxes, so if people are making short films with it they can add text on the screen. Because im on my server and im making a movie where a man is walking down a road and a anvil falls on him and that idea popped into my head.

I really liked the idea of using NPaintPro to create blueprints for turtles, and although there's not much the paint tool can do itself to make turtles understand the image format, I can make creating blueprints easier and cooler with a new display mode:



Though it was sort of designed for building housing blueprints, the gridlines in this mode make lining up distanced images, figuring out dimensions and drawing straighter in general much easier, so it has many uses. However the ability to change the alpha channel is turned off (to make the gridlines easily visible) so for pictures that require both I'd recommend drawing the outline/shape in blueprint mode and then colouring in alpha mode.

One or two bug fixes in this version too, and tester credits to faubiguy

This is an Awesome program nitro! can you select an area then color that selection? or is that a feature that's upcoming? Cheers, ~Dragon

Heracles421, on 25 October 2012 - 04:57 AM said:

I like that new mode. Maybe you could add a way of giving out where a pixel is placed so we can store the x and y coords? Something like paintutils draw function, where we can draw in a certain coord and store the location at the same time. That way I could make the builder

At the moment there's the "flood fill" tool, which works the same as the bucket tool does typically in your standard paint application. Because there's no limit to the size of the canvas (unlike paint), it means you can't just fill empty space- you have to draw something first and flood fill that. At the moment there's no way to fill a selection with a given colour but that might appear in the future…

I'm still not quite sure what you mean Heracles. Again NPaintPro creates image files- you ask to draw in a certain coord and store the location at the same time: that's what the image file is. Save it and then open it in an external program, and extract locational information from there. The tool has to output to a file (it can't simply feed into another program), so you'll have to read that file to know where the pixels are.

Heracles421, on 25 October 2012 - 12:34 PM said:

Ok, from the begining: I want to make a blueprint builder, and I want to know if there's a way to know the exact x and y coordinate when people draw something without an external program. That way I could tell the turtle: Go to x and y, place a block there. I am not sure if you can understand this, but I'm trying my best to explain it.

make your program open the picture file read its continence and use those points as your coordinates.

if there is a 1 on line 2 three places in then use the (3,2)
if there is a 1 on line 6 in position 1 then use (1,6)

All the information you need is stored in the save file you don't need to get any coordinates from npaintpro just interpret its Image file witch is pretty simple btw.

example

making a program that printed out this file using wool would be very simple just a couple of for loops a turtle.forward turtle.place

nitrogenfingers, on 26 October 2012 - 12:27 AM said:

This is the way I'm doing it:

Spoiler

local function loadImage(path)
image = { }
if fs.exists(path) then
  local file = io.open(path, "r" )
  local sLine = file:read()
  local num = 1
  while sLine do
   table.insert(image, num, {})
   for i=1,#sLine do
	image[num][i] = tonumber(string.sub(sLine,i,i), 16)
   end
   num = num+1
   sLine = file:read()
  end
  file:close()
end
return image
end

This will return a table, and any point in the table can be accessed with image[y][x]- this corresponds directly to X-Y coordinates your turtle can use.

Edit: It sounds like you're keen to give this a try Heracles, but would the introduction of a 3D Print function be valuable to NPaintPro?

When one closes(finish editing) a image how does the program save it? anything complicated or is it simple like the basic paint program? [read OP]
would the program be usable with mine if :

'shell.run("paint", "Frame" .. CFrame) –where CFrme is user or automaticaly defined frame number, [except after frame number a extra option would be to save as the npa. extention)

–so
CFrame = 1
–and run the shell command above would yield opening Frame 1 in paint
–once paint is closed with ctrl-enter + ctrl-right-enter (save and close file) it returns to my programs mainmenu automatically

would the above be possible if i used instead :

shell.run("NPaintPro" , "Frame" .. CFrame)

You're of course free to use NPaintPro however you like. If you make something cool, share the link, would love to see what you come up with!

I'm afraid there's no option for specifying the selected frame from the command line- you have to change frames from within the program (with the goto menu option or the <> keys)

I fixed the link to the paint program so it stops sending users to the wrong version. For some reason I have real trouble with the editor on these forums… if you're unable to print, redownload.

BigSHinyToys, on 19 November 2012 - 10:47 PM said:

The forums editor does some strange things like when typing some times the lines jump to the top. Other times links connect to old links when you type them in the same position. disabling Underline a bold then entering re enables them. spaces at the start of lines are removed causes cod to look bad. space between paragraphs vanish some times. it is a real pain to work with it in general. so it is not just you that is having trouble with it.

I copy pasted the code into paste bin so not following the link was unaffected by that problem.

This is a really awesome program I haven't had much time to mess with it thought but I will be using this in my new CC legit world to make fortifications.

nitrogenfingers, on 22 November 2012 - 04:17 AM said:

NPaintPro supports the same file format as Paint. If you want to load a file into NPaintPro that is a paint file however you have to specify by adding a file extension, in this case ".nfp" to the end of your paint file. This tells NPaintPro that it's a standard paint file and opens in a single layer.

There are two modes in NPaintPro, depending on your file type. "Paint" mode just works on a single image, and always saves as a single image. "Animation" mode allows you to edit multiple frames. When saving a file in animation mode, it automatically saves all frames in one file.

You're free to make any changes to the program you need to for your TV program.

I think I found a bug: When attempting to print without fuel, it will turn around and such, and the indicator will move, and at the end it will say "Print succesful", but that's wrong. I think you should check for fuel level so it will tell you when you need to refuel it.

I don't think there's an API for animation yet, and I've been distracted with other work.
You can use the paintutlis library however for drawing images on monitors (using the loadImage and drawImage functions).

When an animation API is released or I release my own, details will be posted here.

nitrogenfingers, on 05 December 2012 - 06:54 PM said:

You can open an NFA file in edit, it's plain text. The format for each image is identical to the NFP/standard picture format that Paint uses, but each frame is separated by a single ~ character.
So I usually have an additional table, the frames table, which in turns stores every image in the animation. When parsing, it's identical to parsing a paint file, but whenever you hit a ~, you just create a new frame and start on the next line.

Awesome idea. Just awesome! I actually got here accidentally, surfing the news about ComputerCraft, but then I saw this 3d printing function… Oh my, I'm playing with it for an hour already )) It's actually a very handy thing in some cases.

I have just one question - how does the turtle "decide" which direction it should start printing? I tried it a couple of times with the same picture and it seems to me that it starts in a totally random direction. Or did I miss something?

ArchAngel075, on 06 December 2012 - 01:55 AM said:

Looking at how I decompile the animation files, i noticed there will be a problem if it hits nil, since i use a '&amp;&amp;' to signal end of file where yours does not…

Any suggestion to detect the end of your files?

-edit-

I will just make it check if a '&amp;&amp;' exists, else toss one at the end before attempting to decompile for safety.

local file = io.open("file")
local line = nil
repeat
  line = file:read()
  --Your parse code here
until not line

local file = io.open("filename", "r")
if file then
  for line in file:lines() do
    --parse code here

nitrogenfingers, on 15 January 2013 - 03:19 PM said:

Correct, flood fill will no fill the whole screen. This is by design- flood fill cycles through a sequence of nodes iteratively nd only stops when there is no space left to fill. The canvas in npaintpro has a dynamic canvas size, which flood fill interprets as infinite. Ergo, filling the null color is impossible, and disallowed.
Your screen is yellow on boot up as this is the alpha channel default colour. You can change it at any time using the "alpha to" commands in the display menu. I expect this will later be replaced with a light/dark grey checker like Photoshop.

Text editing and text paint support has been added to NPaintPro!



Yes, because I clearly didn't think it was bloated enough. This lets you type text and recolour text with the new -t options. Add annotations to your diagrams, flair to your documents or detail to your sprites!

Features:
- Text type support- click or cursor keys to move the text cursor, and type away! Left colour is the text colour, right colour is the background (which can be null)
- Text paint- you can paint the text without destroying the background colour of the scene with this tool. Likewise paint, brush etc. will NOT influence text.
- Load and save with the new .nft file format. This is VERY different to nfp files, the two are not remotely comparable. You can write it yourself fairly simply- it's just plain text (the same as nfp) but the text now translates directly into the text stream of the image. The control characters U+0030 and U+0031 followed by a hex number are used for specifying the background and foreground colour respectively of following text (cheers to Lyqyd for that tip!)

I make no apology for bugs in this code, there are likely to be tons so be careful when using it. Please post any bugs you have here. Thanks, and enjoy!

Thanks for the report TheOriginalBIT :)/>. Have updated both links with the following changes:
- Can no longer cause error when trying to print a blank canvas
- Can no longer cause error trying to change frames in the NFP editor (which is what hitting the numbers outside of Brush mode is effectively doing)
- Turtle will request a refuel if it has no fuel, rather than just go about failing it's movement. The user must take the material in slot 1 out and replace it with fuel, then return to the computer to indicate time for a refuel. It will the carry on printing until material 1 becomes necessary again.
- Added TheOriginalBIT tester credits. If you helped test the program and I've forgotten you, firstly sorry! And secondly let me know, so I can also add your name to the credits. They've incidentally been moved from the splash screen to the help screen, under "About NPaintPro".

Non-ideal I know. Lots of things for the next update, though not sure when it will come:
- Text support! I have specified the NFT file format, and will add editor support for it. If there's demand I'll add also create an NAT file format, for animated text files. It would make sense to replace NFP and NFA with NFT and NAT but I won't for the sake of compatability with paint.
- Choice of your editor mode (paint, animator, textpaint) from the splash screen, rather than by command line option. It's too confusing and doesn't gel with the menu-based front end of the system. Yes it's for power users but that doesn't justify obtuse interfaces.
- Standalone printing. Rather than having NPaintPro handle printing on it's own, you should just be able to copy an NFP or NFA file to a turtle along with 3DPrint, then run "3DPrint <file>"- this will print it automatically, without requiring a network connection with the printing computer. I'll probably leave in direct control of printing, because it sort of looks cool but it's impractical
- An undo-redo function. No idea at all how I'll go about that one, but the program needs it.
- Replacement of the current layer-by-layer display method with a pixel buffer similar to that used in GameUtils (except with a depth buffer), to remove flicker and make the whole thing run a bit smoother. Also makes Layering display an actually useful option, rather than the train wreck it is at the moment.
- A new logo, and maybe a slightly nicer interface. Time for a change, methinks. If you're an artist and have a redesign for the logo, contact me :)/>

Also, I've seen at least one report of issues with the Flood tool but I've not had any luck replicating them. If anyone has any errors with that tool and is able to replicate, please let me know or better yet send an NFP file with that error so I can test and figure out what's happening.

Are chest support planned for the 3DPrint companion app? Would be nice, if say the turtle would return to a chest, when it only have 1 of an item left and restock :)/>

Would save quite some time, having to pendle between the turtle and the computer, all the time, when printing bigger schematics :)/>

Thanks nitrogen! I'm using your program (this) for my OS, KeyOS. Unfortunatley, it isn't finished. That's why it is not on the forums.

if not terminal then terminal = term end

terminal = terminal or term

Used NpaintPro for making editable ruleboards. The server owner's seems happy about them!
This is how it looks(freshly installed):

Basically, startup script starts npaint in the monitor, and a running a function parallely to sleep and queue a key event makes sure the init screen of npaint is bypassed. Dirty, but quick!

Is there anyway you can run an animation outside of npaintpro? For example, some code which allows you to run an animation in a program.

Thanks

now i made another background with npaintpro , with the same name ".background" . . . the question is how do i load the background i made using npaintpro . . . thank you.

bground = paintutils.loadImage(".background.nfp")

Ive always had this suggestion. Transperant 'coating'.(I dont know if theres something else like this but,) This 'coating' allows you to have 2 pictures over each other. This is useful if you want to make A small pic apear over another full-screen menu pic representing something. Its bassicly making a invisible painting in some spots, so you dont have a white blob in your pic. This also saves time so you dont have to redo the whole pic with diffrent stuff on it over and over.(Like again,I dont know if theres a way to do this already.)

This must be the most commonly asked question I encounter…

I've before stated that I don't recommend NPaintPro as a movie development tool- it was designed very specifically to be for animated sprites that would act as components in games built using GameUtils. Play animation libraries are packaged within that suite, and a program to load in and play a looped animation on a blank canvas would probably be about a 10 line program.

But this has come up often enough to suggests there's demand for a tool that can actually be used to make, if not movies at least animated billboards in Minecract. I agree, this is a good idea, but I will say that, at least at present, NPaintPro is just not the tool for that job.

So I'm going to compromise. I'll update the executable in the next few days to include a 'hide' feature, so the interface can be hidden, allowing the program to be run on your machine or on a monitor with the animation you've developed playing constantly. That'll make a sufficient stop-gap for this problem.

And, in the meantime I'll start thinking up some way of making an actual movie development tool in Minecraft…

Nice program. I just got three suggestion for the post to add. first: adding this line is easy but it would help a lot if you have to download npaintpro a lot (like me):

pastebin get pzWSRqNF npaintpro

second: will there ever be a standalone (for use in other operating systems)? The standalone would just need a "Save as…" and a "New" button in the 'file' menu.
third: make flood also flood empty places
that's about it.

The second is something I should do. A standalone version with multiple file access should be available. That just means me adding a browser at some stage, which I'm sure I'll eventually get around to.

I've discussed the third point before, and explained why it isn't possible due to the dynamic nature of the canvas size. Use the brush tool to fill empty spaces.

xXLeNinjaXx, on 24 December 2013 - 01:59 PM said:

Blueprint mode doesn't change anything to do with layering. Just make sure you've opened your file as an animation rather than a paint file (i.e. using the -a command line option).

So I haven't read this thread in months but from the sounds of it there are some issues to solve:
- Stability issues with the main executable
- 3D printing is too complex or confusing to set up, or flat-out doesn't work
- You need a 3D printer and modem in range, and can't print things on their own
- Installation guide and using guide is insufficient.

Thanks for all your feedback. I'll get to work!
