Drawing a rectangular grid

Hi, I'm looking for advice on the best way to draw a rectangular grid with java2d (or other appropraite java). I need to essentially produce a world map on a e.g 200*100 grid, the ocean coloured blue, land in various shades of colour depending on altitude. I want to colour each grid square individually, essentially as if pixel by pixel, and am not sure how best to do this. Do I need to produce 200*100 individual squares and attach them all or is there a way of dividing up a single rectangle into grid squares. Thanks.

use a BufferedImage and increase the scale of the graphics object.

  • Rectangular grid tool versus show grid

    This is probably a stupid question, but can someone explain what is the difference between the rectangular grid tool and the grid accessed from the View menu?
    When might you use one rather than the other? They are both adjustable to the required spacings, so I am unclear about when it would be best to use one rather than the other. I think the reason I am unclear is that I have not fully understood their different functions. Can someone explain them?

    Peter,
    The Document Grid is a non-printing layout aid, like those in most every graphics progam. It's always "there", but can be shown or hidden; it can be set to cause tools to snap to it or not, regardless of if it is showing.
    The Rectanglular Grid Tool is simply a tool for drawing an art item, like an ellipse or polygon. It's just that--a drawing tool. Sometimes you want to draw grids.
    That's not to say you can't use a grid drawn with the Rectangular Grid Tool as a layout aid; you can, just as you can use any path as a temporary construction line. But it's just another of the several tools provided for drawing paths.

  • Polar grids in XY grpah (just like default rectangular grids)

    I want to plot a realtime data of voltage vs time in polar format. I want the polar grids to be dynamic (for eg., rectangular grids in XY graph, which change as I zoom the XY Graph). 
    I have tried "polar plot with points function" and XY graph. I have been successful in plotting the graph. But zoom functionality is very high priorty as it could be hours of data on same polar plot.
    Problem with "Polar Plot function":-
    It gives output as picture unlike XY Graph. I haven't been able to zoom this picture output as we do with XY Graph.
    Problem with "XY Graph Function":-
    I plot the static grid. I plot the real time graph too, but independently. When I try to plot realtime on static grid that I made, it erases the grid and only plot remains. If I try to bundle this realtime plot with other static plots (grids) and plot it just plots it as a static against the grid.

    I have read many forum discussions on this forum bu they don't solve my problem. I am stuck in this problem since some days now, so any help would be appreciated. Its my first post at this forum, so any feedback on my post too will be appreciated.

    Okay, document here how you solved your problem, so later someone with a similar problem can find it.

  • How do I remove the lines from the picture after using rectangular grid tool.

    So I was making a pixel character for test purpose for my game, and after I finish I didn't know how remove the lines without messing up the picture. I use the erase to remove the excess lines. So I was wondering how do I remove the lines within the picture with out messing up the picture.
    I'm going be using the Illustrator and rectangular grid tool for my game pictures. This is in Illustrator CS6.

    If you use the pathfinders unite, you can be left with gaps between your filled objects. If thats the case, use your select menu to select all of one color, then add a stroke with that same color and increase the size of the stroke if necessary. Repeat for the next color until your done.

  • Rectangular Grid Tool - Guide, Anchor, but NO Intersect?

    When using the Rectangular Grid Tool I am starting from the upper edge of the artboard and when moving along the edge I see green indicators stating "Guide" when I am somewhere on the path, and "Anchor" when I am at the edge, "0,0" for instance.
    However, I am trying to follow along with a video tutorial, and in the tutorial it shows the same thing EXCEPT that there is AN "Intersect" value in green in the tutorial. The demonstrator verbally mentions the importance of achieving this "Intersect" value several times. So I am wondering why I am not seeing it.
    The demonstrator mentions making sure that I have "Smart Guides" turned on, and I DO.
    In the video when the demonstrator is hovering over the guide lines with the grid tool it shows two values "PAGE" and "INTERSECT".
    On my local machine when I am hovering over the same guide lines with the grid tool it shows two values "GUIDE" and "ANCHOR".
    I have looked at the preferences when grid tool is selected and played around with different settings. I have also played around with different snap to settings from main menu, and nothing.
    What am I missing?
    Here are two images showing what it looks like in the video tutorial, and what I am seeing locally on my machine when trying to duplicate this myself.
    VIDEO TUTORIAL SCREENSHOT:
    LOCAL MACHINE SCREENSHOT:
    Thank you for looking!

    The grid of guides in the tutorial screenshot shows no guides along the perimeter of the artboard, so there is no anchor point there, just the artboard; the local screenshot has guides on the perimeter, so the label correctly shows an anchor point in the corner. You would need to go to View > Guides > Lock to deselect Lock so that you can select and delete the offending guides. Smart Guides will then show intersect at the corner of the artboard and page anywhere else along the edge.
    Intersect appears where two paths cross without an anchor point.

  • Drawing a warped grid in perspective???

    Now...... i know how to use the perspective tool and i understand that i can draw a grid onto this but the grid always seems to be out of whack when i do and the line spacing isn't at all perfect.  What i want to be able to do is draw a grid with equal spacing and have the ability to warp this so it looks all bent up going off into the distance.
    I can see this is going to be something that i have to draw in manually but i'm kind of hoping that i can have the bulk of the job done for me. 
    However, if i do have to draw it manually, how would i go about spacing the lines equally along a wafty curved line???

    Actually, upon playing about with this, i seem to have got exactly wat i was after    Thanks a lot

  • How to interactive-draw on a grid?

    Hello!
    Imagine you had set up a grid based on little 1x1px boxes.
    Wouldn’t it be cool to take your Wacom-Pen and simply color the boxes the way you’d love to?
    You could simply set up a solid brush matching your needs …no matter if it’s 1x1 px thin. …or 1000x1000 px heavy.
    You could create sharp edged drawings in beautiful colors.
    Well, that’s pretty the kind of set-up I’m looking for.
    But instead of that solid look, I get shades or halftones even if my brush is set to 1px.
    Anyone an idea how to create a sharp-edged brush-set-up?
    Any hints would be much appreciated
    G

    how about making a grid of actual 1px X 1px squares...
    Yes, and one could use the Rectanglular Grid tool to create the grid and not mess with snaps or the document grid at all. And using that method, there would be no reason to draw the grid to a measure of 1 "pixel" (1 point) at all. At that size, you would have to zoom in to see what you're doing and zoom out to see what the finished results will look like at "actual size."  So instead, you could draw the grid of squares to any arbitrary scale, flood fill them, and then scale the results to the desired vector-squares-per-inch size.
    But (beside the pointlessness of the whole exercise, which I hope is becoming evident) that does not satisfy G's desire to use a pressure-sensitive Wacom stylus to interactively adjust the fatness of his swipes.
    Functionally, what G desires is exactly what any ordinary bitmap program (assuming pressure-sensitivity support) does and has been doing for decades, when painting at low res or high zoom with antialiasing turned off (or some other means which disallows it, such as painting in limited index color mode).
    What G is failing to realize is that drawing a mosaic of vector squares is essentially the same thing as coloring aliased pixels. A pixel is essentially a call for a colored square. You can scale and rotate that raster pixel every bit as much as you can scale and rotate a vector square. In other words, by wanting his vector drawing to consist of nothing other than squares, he is essentially desiring to circumvent the resolution-independent rasterization of vector drawing.
    So G may argue, "But James, by drawing with vector paths, I can have adjustability of the array of squares! If only I had the new kind of pressure-sensitive brush I want, I could reshape the spine path which auto-generates the array of squares!"
    And I would answer: Yes. But that's exactly what you would have if you simply turned off antialiasing and used any of the existing Brushes (and/or any of the other drawing tools, like the Blob tool), and otherwise used those tools normally. Getting a "scaleable" version of the artwork with the desired number of "squares" is a simple matter of zooming (thereby controlling the number of rows/columns of squares) and taking a screen capture (because, as demonstrated, scaling an aliased raster image is for most practical purposes functionally equivalent to scaling an array of vector squares).
    If you want to see how many "squares" are created as you draw, you could even use a screen magnification utility, like the Magnifier built into Windows. But in practice, that's rather antithetical to the notion of pressure-sensitivity; you don't really want to "count pixels" as you go with an interactively pressure-sensitive "painting" tool.
    So again; the whole idea is so much like just wanting to make Illustrator act exactly like what any aliased painting method does in even the cheapest raster program, that it raises the question, "Why reinvent the wheel?" Just use a paint program--or turn off antialiasing and take a screen shot, and you've got the "new feature" that you want, without hoping and waiting for Adobe to ever add such a (frankly quite dubious) feature.
    In a nutshell, the primary intent and purpose of the resolution independence of vector drawing is to avoid the aliasing inherent in raster imaging--exactly what G now wants to preserve. So simply use raster imaging, and you'll have your aliased artwork, and it will be scaleable.
    There's no need to re-invent the square wheel. The square wheel is easy. The whole purpose of vector drawing is to avoid square wheels. If you want square wheels, you don't need vector squares.

  • How to create an interactive rectangular grid in labview.

    Hello everyone I want to create a grid in labview in which If I click in any block it should change colour and say it changes from intially white to red, than blue. And I want to save the data representing the colour like 0, 1, 2 , 3 to an array. Can anybody help me, where should I start with?? Can you please direct me towards any example.
    Solved!
    Go to Solution.

    Ah sorry, the posted VI has an array of pictures instead on an array of picture rings as I suggested. Thus my reply does not apply directly.
    I recommend a array of picture ring indicators, since there is only a small set of possibilities.
    You coulds use code similar to the one shown in the link of this post:

    Alternatively, you could make the entire grid as one big picture.

  • Setting Up Rectangular, for example 16:9 with different subdivisions, Grid (View Show Grid)

    The Grid tool (View > Show Grid) is a huge help when designing. Unfortunately, by default AI allows us to specify only square grids, i.e. you set one parameter for gridline spacing (and one for its subdivisions) and AI creates square grid applying your value for both: horizontal and vertical directions. But what if we need something more, for example 16:9 proportion grid (subdivided into 4 parts in horizontal direction and 3 in vertical)? Hmm…. actually… we can do this! We can even set different colors for the main and subdivision lines:

  • For Guides & Grid: Make rectangular (4:3, 16:9, etc.) units possible

    Problem
    Right now it is difficult to align 4:3 and 16:9 artboards to the grid since today, only square grid units are possible.  This is annoying because when the grid and artboard don't align, laying things out by the grid becomes pretty useless.  Snapping to grid and moving objects with the arrow keys is annoying too because the object will always move a couple times per unit (once when one side is aligned, and again when the other side is aligned).  Yeah, you could do math and figure out how to divide up 1280 x 720 squarely, but that's hard. 
    Solutions
    One solution is to give us the ability to specify different vertical and horizontal subdivision numbers.
    The other is to give us some presets so that the grid units are square, but you did the math for us.

  • Draw a grid(different)

    Hi,
    I am trying to draw a circular grid, i.e. like a dartboard, where each ring is split into a number of parts.
    So far I have managed to do that by drawing an image of the board. This creates other problems like reading mouse clicks,scaling, and placing components in correct coordinates.
    I can provide more info. Thank you

    This kinda solves my problem
    for(int i = 0; i < 8; i++)
                   g2d.draw(new Ellipse2D.Double(i*45, i*45,
                        getWidth()-(2*i*45),
                        getHeight()-(2*i*45)));
    for(int i = 0; i < 24; i++)
                   double temp = Math.toRadians(i*15);               
                   Line2D line = new Line2D.Double(getWidth()/2,getHeight()/2, getWidth()/2,0);
                   g2d.draw(line);               
                   at.rotate(Math.toRadians(15),(getWidth()/2), (getHeight()/2));
                   g2d.setTransform(at);
    }This draws the grid. Now if I want to place something or read a click my best bet is:
    x = a + r cos(t)
    y = b + r cos(t)
    So a code of this sort:
    Point point = new Point((int)(center.x+(getWidth()/2)*Math.cos(temp)),
                             (int)(center.y+(getHeight()/2)*Math.sin(temp)));Will produce results slightly different from the actual drawing.
    Thanks again for the help

  • Best technique for creating an isometric grid

    I know there are plugins to make isometric grids. I just want to draw one and have it available for later usage. How can I create this? (I am new to Illustrator and have no experience making custom grids.)
    Thanks!

    There are no true "custom grids" in Illustrator (in the sense of angled snap grids), just as there are no custom rulers.
    If you feel you must use a grid for isometric drawing, you can fake it by several methods:
    1. Draw an array of lines. Put them on a locked layer. Snap to point and SmartGuides will snap to them, even though they are locked.
    2. Draw the array of lines. Convert them to Guides.
    3. Use the Grid Tool to draw a square grid, rotate it 45°, scale it vertically 57.7%, put it on a locked layer or convert it to Guides.
    4. Draw two short lines of the same length (one at 30°, the other at 150°), centered on each other, and use that figure to create a Pattern Swatch. Draw a rectangular path, fill it with the Swatch. Expand the fill so that snaps will work on it.
    All the above have their drawbacks. 1, 2, and 3 are cumbersome because if your page size changes, the grid has to be changed, moved, or added to accordingly. (Unless you draw the grid to fill the entire pasteboard). 3 is awkward because of all the extraneous trash Illustrator is so prone to creating (unfilled, unstroked paths and clipping masks in expanded results).
    I don't use a grid when drawing isometric in Illustrator. I just use SmartGuides. Look it up in online Help. Set the construction guides to 15° increments (or set custom angles to 30°, 150°, and 90°.)

  • Need help making slanted grid

    Hi! I'm looking to make a landscape image similar to the one below by first making the grid and then filling it in with the paint bucket. Note I DO NOT WANT PERSPECTIVE, so the perspective grid tool isn't helpful. I've tried messing around with the rectangular grid and mesh tools but I'm very new to Illustrator and can't get what I want. Any help is appreciated, thanks!
    I'm using Adobe Illustrator CS6 by the way.

    Note I DO NOT WANT PERSPECTIVE
    Yes you do. What you've shown is perspective. It's just parallel perspective instead of converging perspective.
    You don't really need grids for such things, but if they make you feel comfortable, you might consider Serif DrawPlus. It costs less than $100, can draw to user-defined scale, and has a context-sensitive axonometric grid feature that's right up your alley.
    It neatly works around the usual problems associated with most grid attempts by displaying only the plane you are currently working on, and interactively switching to another plane when you select an object on that plane. Example:
    1. Set the current plane to what the program calls the Top Plane. The top plane grid displays. The shape drawing tools automatically conform to that grid:
    2. Set the current plane to what the program calls the Front Plane.The left plane grid displays, and the shape drawing tools automatically conform to it.
    3. Set the curent plane to what the program calls the Right Plane. The right plane grid displays, and the shape drawing tools automatically conform to it.
    Now here's the neat part.
    4. You want to draw the next surface that's parallel to the Top Plane. You just click an object already drawn on that plane and it switches you to that grid. Of course, by clicking that object, you've also changed the current stroke and fill to the colors of those of that object, so you're automatically all set to draw the top of the next terrace with whatever shape tool you have in hand.
    5. Similarly click a shape already on the left plane and the current color, grid and auto-conforming behavior of the shape tools switch to that orientation.
    6. Click a shape already on the right plane and the color, grid, and shape behavior switch to that plane.
    And so on. Note that the bounding boxes of the shapes conform to the current plane. So dragging the middle side handles stretches the shapes as you would expect, parallel to the grid lines of the plane the object is on. And it's not just the rectangles, but all the other pre-defined shape tools auto-conform, too. So you get accustomed to it in a few minutes and can proceed quite quickly.
    So it's sort of like the FreeHand / Illustrator perspective grid, except it does parallel perspective.
