I'm building a color box connecting game with objective-C and trying to figure out how to find the correct position when a block of boxes is placed incorrectly over another block of boxes.
See the attach image. In the image, you only need to move the left box one step to the right in order to connect the boxes and win.
However, if you place the left box on top of the other box (Image 2), I want to move it to the closest available free grid position.
This would be easy if the box was a simple square (a 1x1 grid, 2x2 grid, etc), but since the boxes can be complex, It's harder. There might also be a lot of boxes on the grid.
Any suggestions would be very appreciated.
If you're new to heuristics like this, just take the KISS approach.
It couldn't be easier...
The user tries the object at x,y ok?
It does not "fit" there.
So, simply "spiral" outwards, trying it in other possible places.
Just keep trying until you find one where it fits.
234
915
876
so that's like "radius 1", you see? then try "radius 2"
and so on.
It's that easy. Just keep trying until you find one that "does work".
Work from the start position outwards, so that, you find the closest one.

For the context, I'm working with Capella, an Eclipse RCP application based on Sirius (hence, EMF, GMF and draw2d). This application is used for MBSE, that basically means diagram representations for industrial systems.
I'm developping an add-on (viewpoint) to display custom labels next to diagram elements. These diagram elements are, to put it simply, boxes inside boxes. My problem is that usually the label text is larger than the space between a box and its container, so the label gets hidden. What I need is these labels to always be in foreground. As I'm more used to web development, what I'm looking for would be the equivalent of the z-index CSS property.
Currently I have no idea of how to achieve this, I'm using a custom .odesign that allows me to control some rendering options, like labels text, the color of some elements or to add decoration, but I dont think its the way to go for my problem. Maybe I should use a custom EditPart or a custom StyleConfiguration (I already used these components for other projects) but I have no clue where to start for this issue.
Any leads will be greatly appreciated.
We recently did this kind of changes to keep some labels in Sirius Sequence diagrams always on top: the combined fragments are placed behind the lifelines (z order) but we wanted to keep the labels of the CombinedFragments visible event their bounds intersects Lifelines, Executions or States).
This has been handled in Bug 564239 for Sirius 6.3.2 (used in Capella 1.4.1).
You could find some hints the bugzilla (Gerrits and commits can be retrieved from the See also section).
In Sirius Sequence diagram , we use org.eclipse.sirius.diagram.sequence.ui.tool.internal.layout.SequenceZOrderingRefresher to control the z-order of CombinedFragments : all the figures that composes them comes from some expressions in the odesign, and synchronization with the Capella model for exemple.
But in your case you want to control only the label, so it must not be dealt on the edit par level, but on the figure one. The "overlay" layer and figure lead might be a good one.
Do not forget another thing: in GMF/GEF, the labels of an element is displayed/shown/rendered/visible if it fits to the visible area of the parent container: in the case of a node in a container with scrollbar, the visible are will impact the visibility of the sub nodes (extended to their border nodes, edges, labels, ...)

Looking for some help or to be pointed in the right direction. Been stuck on this for a while and the main issue is I don't even know where to start. I am sure there is a solution but my brain will not see it.
To use as an example I have a table that shows monthly results for multiple different areas:
What I want to do is in the gap along side each number is show an increase, decrease or no change, using up arrow down arrow and square. That I can do using conditional formatting my issue comes with the fact that I also want it to be multiple Colours. So it will take into account increase and decrease and whether they are in target.See below:
Atm I am copying and pasting each month. But having it automated would be amazing. The outcome would hopefully look like this:
I am hoping there is a way that I can do two things compare to the previous month and then check it against my table to see where it sits then display the appropriate symbol.
Thank you in advance for any help or a place to start.
So extremely easy to figure out once I looked at it in a simplistic way.
Firstly, I used: =IF(-SIGN(E26-G26)= 0, "n", IF(-SIGN(E26-G26)=1, "é", IF(-SIGN(E26-G26)=-1, "ê","")))
To compare the current number to the previous number and get a 1, 0 or -1 depending on if it had gone up down or stayed the same, using this it either displays é, n or ê. I then set the font on these cells to Wingdings. so they become up arrow, down arrow and a square.
Then I use conditional formatting to colour it based on the adjacent cells value.
No need for a long, complex formula
=IF(A2>A1,"t",IF(A2<A1,"u","v")) - set the font to Marlett
While using Delphi Seattle 10 and Steema TeeChart Pro VCL FMX 2016.18, I am looking to Highlight a Selection of a Line Graph (multiple series) in the way that Zooming allows / makes a square around a highlighted selection of a Line Graph to indicate which part of it to zoom into (as long as the onmousedown action is in progress).
The purpose of this would be to allow the selection to remain highlighted while the mouse is no longer being clicked, to potentially "Delete" the highlighted Data points. All I need this for is to obtain the (X0 Y0 X1 Y1) values to possibly obtain the CalcPosPoint(X) and remove all the points inside. The data is currently obtained through a Record Struct (Memory Mapped) file, and it will there for be used to set/check for a property "deleted" to indicate on the next redraw of the graph which rows to completely ignore and which to continue printing.
I hope to be able to do this (select from 1 chart), and have it simultaneously draw on multiple graphs. I have tried to look for an example of this feature through the use of TSelectorTool (FMXTee). One of the pages I found referring to such a tool is Interactive data point selection as well as Multiple selections with Selector Tool
And my second question has to do with TeeCharts directly. Where would I find fmx240.bpl as TeeChart_Pro_Firemonkey_Demo.exe requires this file in order to run? I did manage to copy vcl240.bpl from "Embarcadero\Studio\18.0\bin" and put it into "Embarcadero\Studio\17.0\bin"

I have managed to capture / create a sample code (MVCE) from which I can now select a portion and create a square around a particular sample of graph lines.
The control graph right now is the bottom graph (Chart5). If anyone is interested in seeing the code, I have put up a pastebin sample.
PasteBin Sample Code
And a TeeCharts.tar.gz is accessible to anyone who wishes to see a sample of the code, as well as the data sample.

I no longer feel the need for mathematical equation to differentiate the top graphs from the bottom (because the bottom axes are automatic where as the top are defined). I intend to only use the space which is adherent to the visible space, and do not intend to extend in either direction (left or right). That means at this point the size of the graph does not matter, because once I over populate the charts above, the position in the bottom graph would become irrelevant, and therefor I do not intend to use the bottom chart.
The next step is to save the positions of the boxes so that they can reappear when the graph is shift from left (past data) to the right (live data). And then uses the buttons above to make the appropriate action to the graphs.
I would like to know what way would be the most sufficient way to record the positions of the rectangles, so when the chart is shifted (via the ScrollBar1), the rectangles are moving with the direction of the scrollbar. But I'm sure I can achieve that.
I think I have found a solution. The red squares are only prevalent for the visual aspect, they can be drawn on, I don't need to do anything special with each chart, as I already know what the X0..Y1 parameters are, they are known from the initial chart. The problem h/e has to do with the initial chart. As long as the screens are all full, I can zoom in correctly w/ alignment with on all the charts (ZoomRect/Rectf(X0..Y1))
But what kind of equation would it take to adjust the charts that are not in the same zoom / max / min when the Chart5.Axes.Bottom.Automatic = True?
From there I just simply have to disable the immediate zoom feature, and allow buttons to become functional, to decide what the next course of action would be.
I have an image with a group of cells and I need to count them. I did a similar exercise using bwlabel, however this one is a bit more challenging because there are some little cells that I don't want to count. In addition, some cells are on top of each other. I've seem some MATLAB examples online but they all involved functions that aren't available. Do you have any ideas how to separate the overlapping cells?
Here's the image:
To make it clearer: Please help me count the number of red blood cells (which have a circular shape) like so:
The image is in grayscale but I think you can distinguish which ones are red blood cells. They have a distinctive biconcave shape... Everything else doesn't matter. But to be more specific here is an image with all the things that I want to ignore/discard/not count highlighted in red.
The main issue is the overlapping of cells.
The following is an ImageJ macro to do this (which is free software too). I would recommend you use ImageJ (or Fiji), to explore this type of stuff. Then, if you really need it, you can write an Octave program to do it.
run ("8-bit");
setAutoThreshold ("Default");
setOption ("BlackBackground", false);
run ("Convert to Mask");
run ("Fill Holes");
run ("Watershed");
run ("Analyze Particles...", "size=100-Infinity exclude clear add");
This approach gives this result:
And it is point and click equivalent as:
Image > Type > 8-bit
Image > Adjust > Threshold
select "Default" and untick "dark background" on the threshold dialogue. Then click "Apply".
Process > Binary > Fill holes
Process > Binary > Watershed
Analyze > Analyze particles...
7 Set "100-Infinity" as range of valid particle size on the "Analyze particles" dialogue
On ImageJ, if you have a bianry image, watershed actually performs the distance transform, and then the watershed.
Octave has all the functions above except watershed (I plan on implementing it soon).
If you can't use ImageJ for your problem (why not? It can run in headless mode too), then an alternative is to get the area of each object, and if too high, then assume it's multiple cells. It kinda of depends on your question and if can generate a value for average cell size (and error).
Another alternative is to measure the roundness of each object identified. Cells that overlap will be less round, you can identify them that way.
It depends on how much error are you willing to accept on your program output.
This is only to help with "noise" but why not continue using bwlabel and try using bwareaopen to get rid of small objects? It seems the cells are pretty large, just set some size threshold to get rid of small objects http://www.mathworks.com/matlabcentral/answers/46398-removing-objects-which-have-area-greater-and-lesser-than-some-threshold-areas-and-extracting-only-th
As for overlapping cells, maybe setting an upperbound for the size of a single cell. so when you have two cells overlapping, it will classify this as "greater than one cell" or something like that. so it at least acknowledges the shape, but can't determine exactly how many cells are there
I am creating a game board using Expression Blend with lots of irregular shapes. These shapes will have text blocks on them as labels. For a given shape and its text block, I want them to behave as one control. An example: on a blackjack table the "Insurance" betting area is a curved area with text that reads "Insurance Pays 2 to 1". What is the best way to make those to behave as one control? In this example, if I drag a chip on to either control - the text of the betting area - it should respond the same way. Would it be to make it into a user control? If not, what is a better way to accomplish this?
Answered over on Expression Forum for anyone else it helps. :)
