I trying to create a network architecture using vertex and edge objects from mxGraph.
Now in first image ZCU_08_01 is connected to ZCU_01_01 as you see.
Is possible the modification using edges like in next image ? And if possible, how? (of course assuming straight line sections not "hand made" :) )
The edge is defined:
var E33 = graph.insertEdge(parent, null, '', ID618, ID620,'strokeColor=#FF0000;');
and the style definition for edges is:
style = graph.getStylesheet().getDefaultEdgeStyle();
style[mxConstants.STYLE_EDGE] = mxConstants.EDGESTYLE_ORTHOGONAL;
style[mxConstants.STYLE_EDGE] = mxConstants.EDGESTYLE_SIDETOSIDE;
style[mxConstants.STYLE_ENDARROW] = mxConstants.NONE;
style[mxConstants.STYLE_ROUNDED] = true;
Thank in advance

I need to get the co-ordinates of matched image within the actualImage so that I can perform operations on it. However, I tried below two approaches,but both doesn't seem to work:
Approach 1:
Using below, I'm able to find a match but co-ordinates returned are just the width & height of image to be matched(which I already know). I want to get the position of the same within actual image.
BufferedImage actualImg = ImageIO.read(new File("C:/Images/SrcImg.PNG"));
ImageTarget actualTgt = new ImageTarget(actualImg);
BufferedImage searchImg = ImageIO.read(new File("C:/Images/TgtImg.PNG"));
ImageTarget searchTgt = new ImageTarget(searchImg);
ScreenRegion scrReg = new StaticImageScreenRegion(actualTgt.getImage());
ScreenRegion resReg = scrReg.find(searchTgt);
ScreenLocation center = resReg.getCenter();
System.out.println(":getElementFromImage: x_loc,y_loc =["+center.getX()+","+center.getY()+"]");
Approach 2:
In below code I tried with sikulix Finder. However, with this src.hasNext() returned true BUT src.next() threw nullpointer exception.Not sure what is the problem here:
Finder src = new Finder("C:/Images/SrcImg.PNG");
Pattern pat = new Pattern("C:/Images/TgtImg.PNG").similar(0.5);
src.find(pat);
Match m;
while( src.hasNext())
m = src.next();
src.destroy();
java.lang.NullPointerException
at org.sikuli.script.Finder.next(Finder.java:484)
at com.work.ImageFinder.main(ImageFinder.java:38)
I already spent good amount of time to make this work. Any help would be much appreciated.
Thanks!
It works fine after passing the Region to Finder like below:
Finder src = new Finder("C:/Images/SrcImg.PNG", new Region(0,0,<width>,<height>))
Pattern pat = new Pattern("C:/Images/TgtImg.PNG").similar(0.5);
src.find(pat);
Match m;
while( src.hasNext())
m = src.next();
src.destroy();

Is it possible to use Sikuli to assert that images are the same in GUI-less mode?
I am trying to combine LineSeries, ScatterSeries and HeatmapSeries on a single OxyPlot instance. I am able to show the first two just fine on the same plot and it looks like the following:
The axes for this are generated by the following code:
var xAxis = new DateTimeAxis();
xAxis.Key = "X";
xAxis.Position = AxisPosition.Bottom;
xAxis.AbsoluteMinimum = DateTimeAxis.ToDouble(CurrentPass.AOS);
xAxis.AbsoluteMaximum = DateTimeAxis.ToDouble(CurrentPass.LOS);
xAxis.AxislineColor = xAxis.TextColor = xAxis.TicklineColor = xAxis.MajorGridlineColor = OxyColors.DarkGray;
var yAxis = new LinearAxis();
yAxis.Key = "Y";
yAxis.Position = AxisPosition.Left;
yAxis.AbsoluteMinimum = 0.0;
yAxis.AbsoluteMaximum = MaximumFrequency;
yAxis.Maximum = MaximumFrequency;
yAxis.AxislineColor = yAxis.TextColor = yAxis.TicklineColor = yAxis.MajorGridlineColor = OxyColors.DarkGray;
If I add in a third axes for the Heatmap (not even a HeatMapSeries yet), I get the following:
The extra code here for the axis for the HeatMap is:
var heatmapAxis = new LinearColorAxis();
heatmapAxis.AbsoluteMinimum = 0.0;
heatmapAxis.AbsoluteMaximum = MaximumFrequency;
heatmapAxis.Palette = OxyPalettes.Gray(1024);
heatmapAxis.Key = "HeatMap";
I am not sure what's going on here. The line series still shows. And all the ScatterPoints from the scatterseries I have are definitely there - the tracker shows up and I can interact with the points (hover, click etc.). But the points don't show. If I add a HeatMapSeries, the HeatMapSeries data does show up as expected, the LineSeries data still shows up but no ScatterSeries data.
Again, the HeatMap data and the Scatter Series data show up individually, but never together.
Has anyone encountered this before? Are there workarounds?
Thanks,
Aditya
Sorry this is a bit late but just stumbled upon this. I had something similar with a line not showing up on a Heatmap and after some experimenting i realized the order in which the series' are added to the plot model make a big difference. Make sure you add your ScatterSeries after you've added your Heatmap to the plot model.
I need to change color of my particle effect color according to some user event in my game for that this is what i am doing:
float temp[] = new float[4];
temp[0] = 0.937f;
temp[1] = 0.325f;
temp[2] = 0.314f;
pe.getEmitters().first().getTint().setColors(temp);
pe.start();
and in render i am doing this:
pe.draw(batch, Gdx.graphics.getDeltaTime());
but unfortunately i am getting this error:
java.lang.ArrayIndexOutOfBoundsException: length=4; index=4

i dont know what i am doing wrong, i read the documentation and has done everything according to it any help would be a savior... Thanks in advance..
Your float array has the wrong length.
You actually don't need to create a new array. You can avoid this problem altogether by filling your colors into the array it already has like this:
float temp[] = pe.getEmitters().first().getTint().getColors();
temp[0] = 0.937f;
temp[1] = 0.325f;
temp[2] = 0.314f;
pe.start();
I would like to add to my plot a text or a legend box with comments.
At the moment my legend is plot at northeastoutside and i would like to add the new legend (or textbox) to the position southeastoutside.
Thanks!
Lacking more information about your case:
To the best of my knowledge one axes object can only have a single legend object. You can create a second legend with a second axes object. Each legend will only list data elements associated with each axes. Adapted from Matlab Newsgroup thread
a = [1:0.01:2*pi]; %create sample data
b = sin(a);
linehandle1 = line(a,b); %creates a line plot with handle object
axeshandle1 = gca; % gets the handle for the axes object just created
legendhandle1 = legend('y = sin(x)', 'location', 'northeastoutside'); %makes first legend
axeshandle2 = axes('Position',get(axeshandle1,'Position'),'xlim',get(axeshandle1,'xlim'),'ylim',get(axeshandle1,'ylim'),'Visible','off','Color','none'); %makes invisible axes with same position and scaling
linehandle2 = line(pi/2,1,'Color','r','Marker','o','Parent',axeshandle2); %puts data set on 2nd axes
linehandle3 = line(pi,0,'Color','b','Marker','x','Parent',axeshandle2);
legend_handle2 = legend('peak','zero','location','southeastoutside'); %creates legend to go with 2nd axes
If you just want text in that 2nd box, not necessarily legend info or data labels, you can play around with annotation as described above. This has the advantage of being simpler to call, but maybe harder to get the exact position/result you want. There are a large number of property options that can be adjusted to get the desired appearance. A few are shown in the example. It may be there are easier ways to set the size/position based on the legendhandle.
a = [1:0.01:2*pi]; %create sample data
b = sin(a);
plot(a,b);
legendhandle = legend('y = sin(x)','location','northeastoutside');
annotation('textbox',[0.875 0.1 0.1 0.1],'string','my text','edgecolor','k','linewidth',1,'fitboxtotext','off');
I am trying to mask an image on another so that I only view the specific portion of the unmasked image through the masked one. My problem is that I cannot see anything on the screen.. no Image, no effect at all
cardMask = new Image(Root.assets.getTexture("card_mask"));
cardMask.y = Constants.STAGE_HEIGHT*0.40;
cardMask.x = Constants.STAGE_WIDTH *0.48;
trace("it's add mask");
cardLight = new Image(Root.assets.getTexture("card_light_mask"));
cardLight.y = Constants.STAGE_HEIGHT*0.46;
cardLight.x = Constants.STAGE_WIDTH *0.48;
cardLight.mask=cardMask;
maskedDisplayObject = new PixelMaskDisplayObject(-1,false);
maskedDisplayObject.addChild(cardLight);
maskedDisplayObject.x=cardLight.x;
maskedDisplayObject.y=cardLight.y;
maskedDisplayObject.mask=cardMask;
maskedDisplayObject.blendMode = BlendMode.SCREEN;
addChild(maskedDisplayObject);
First, for masking an object the mask object should also be added to the display list. Your code does not add cardMask to display list anywhere. Second, if your maskedDisplayObject should be visible at all times, the mask should be assigned not to it, but to some other object which displayed part you desire to control. And third, it is also possible that this.stage is null, therefore the entire tree (this -> maskedDisplayObject -> cardLight) is plain not rendered. You need to check all three of these conditions to get something displayed.
Also, if you desire cardLight as an object to move independently of maskedDisplayObject, you should add it to this instead, and check that it's displayed on top of maskedDisplayObject (call addChild(cardLight) after addChild(maskedDisplayObject)).
This all totals to this code:
trace("Stage is null:", (this.stage==null)); // if this outputs true, you're out of display
cardMask = new Image(Root.assets.getTexture("card_mask"));
cardMask.y = Constants.STAGE_HEIGHT*0.40;
cardMask.x = Constants.STAGE_WIDTH *0.48; // mask creation unaltered
trace("it's add mask");
cardLight = new Image(Root.assets.getTexture("card_light_mask"));
cardLight.y = Constants.STAGE_HEIGHT*0.46;
cardLight.x = Constants.STAGE_WIDTH *0.48;
cardLight.mask=cardMask; // this is right
maskedDisplayObject = new PixelMaskDisplayObject(-1,false);
// maskedDisplayObject.addChild(cardLight); this is moved to main part of display list
maskedDisplayObject.x=cardLight.x;
maskedDisplayObject.y=cardLight.y;
// maskedDisplayObject.mask=cardMask; NO masking of this, you're only masking cardLight
cardLight.blendMode = BlendMode.SCREEN; // display mode is also changed
addChild(maskedDisplayObject);
addChild(cardLight);
