I was wondering if there is a more specific way to rename my shape extracted from a contour effect than using ActiveLayer.Shapes(2)? The main thing I don't like about this method is it's general and I'm afraid that somewhere down the road it might not be Shape(2) anymore, causing issues. My hope is to define it by name, but I don't know what that is since it's created via an effect.
Is there by chance a function or something to look up an unknown shape name?
I found .findeshape, but I couldn't get it to work and I'm not sure if that's what I actually need in this instance. Any help is appreciated.
'Create Rectangle
Set Rect = ActiveLayer.CreateRectangle(1, 1, 0, 0)
'Apply .1" Outside Contour.
Set Contour1 = ActiveLayer.Shapes(1).CreateContour(cdrContourOutside, 0.1, 1, cdrDirectFountainFillBlend, CreateCMYKColor(75, 68, 65, 90), CreateCMYKColor(0, 0, 0, 100), CreateCMYKColor(0, 0, 0, 100), 0, 0, cdrContourSquareCap, cdrContourCornerMiteredOffsetBevel, 15#)
ActiveDocument.CreateSelection Contour1.Contour.ContourGroup, ActiveLayer.Shapes(1)
ActiveSelection.Separate
ActiveLayer.Shapes(2).ObjectData("Name").Value = "Renamed 2"
End Sub```

I want to render an image from a visualized match result with a colored pointcloud.
In the example program find_surface_model_with_edges_simple.hdev after running find_surface_model() you receive a pose, with this pose you can visualize how the surface model matched in the scene using: visualize_object_model_3d(). From a visualization like this I want to create a rendered image to display the matching result in an application I am making.
To render a colored pointcloud I use:
render_object_model_3d (Image, ObjectModel3DSceneRaw_ccs, camPar, Pose_0, ['red_channel_attrib','green_channel_attrib','blue_channel_attrib'], ['&overlay_red','&overlay_green','&overlay_blue'])
To render a match result I use:
render_object_model_3d (Image, [ObjectModel3DSceneRaw_ccs, ObjectModel3D], camPar, [Pose_0, detectedPose], ['color_0', 'color_1'], ['white', 'red'])
I can not get the two objects in this function and still have the RGB attributes, Halcon gives parameter errors. I would also like to specify the color of the objectmodel.
I also tried to use 3D scene:
create_scene_3d (Scene3D)
add_scene_3d_camera (Scene3D, camPar, CameraIndex)
set_scene_3d_camera_pose (Scene3D, CameraIndex, detectedPose)
add_scene_3d_light (Scene3D, PoseInvert[0:2], 'point_light', LightIndex)
* The scene
add_scene_3d_instance (Scene3D, ObjectModel3DSceneRaw_ccs, detectedPose, InstanceIndex)
set_scene_3d_instance_param (Scene3D, InstanceIndex, ['red_channel_attrib','green_channel_attrib','blue_channel_attrib'], ['&overlay_red','&overlay_green','&overlay_blue'])
* The transformed objectModel
add_scene_3d_instance (Scene3D, ObjectModel3DRigidTrans, Pose_0, InstanceIndex2)
set_scene_3d_instance_param (Scene3D, InstanceIndex2, 'color', 'red')
* Display
display_scene_3d (WindowHandle, Scene3D, CameraIndex)
But this only shows the scene and not the matched objectmodel.
Anyone know what I'm doing wrong?
This hack worked well enough for my purposes:
HT empty = new HT();
hop.CreatePose(0, 0, 0, 0, 0, 0, "Rp+T", "gba", "point", out HT pose_0);
HT camParam = new HT(0.008, 0, 0, 0, 0, 0, 5.2e-006, 5.2e-006, 960, 600, 1920, 1200);
HT renderGenParam = new HT("red_channel_attrib", "green_channel_attrib", "blue_channel_attrib");
HT renderGenValue = new HT("red", "green", "blue");
hop.ReadObjectModel3d(om3Path, 'm', empty, empty, out HT om3, out HT status);
hop.RenderObjectModel3d(out HObject sceneImage, current_OM3, camParam, pose_0, renderGenParam, renderGenValue);
hop.RenderObjectModel3d(out HObject objectImage, om3, camParam, avg_pose, "color_0", "green");
hop.AddImage(sceneImage, objectImage, out HObject resultImage, 0.6, 0);
hop.CropRectangle1(resultImage, out HObject resultCropped, 250, 400, 935, 1450);
hop.WriteImage(resultCropped, "tiff", 0, #"./testImage.tiff");
Not a real solution tho.
I've gone through formatting settings and stack overflow posts, I've toggled with a bunch of different settings and can't seem to find an answer to this.
Two VS Code extensions come into play here: Prettier and Better Align. I want to use Prettier to format my code generally, and Better Align to align certain pieces of my code. But Prettier overwrites any changes that I make with Better Align.
For example:
After running Better Align, before running Prettier:
<ReactMapGL
{...this.props.viewport}
zoomEnabled = {true}
showUserLocation = {true}
mapStyle = {this.props.mapStyle}
mapboxApiAccessToken = {process.env.REACT_APP_MAPBOX_TOKEN}
onViewportChange = {(viewport) => {
this.props.updateViewport(viewport);
}}
>
Then, after running Prettier:
<ReactMapGL
{...this.props.viewport}
zoomEnabled={true}
showUserLocation={true}
mapStyle={this.props.mapStyle}
mapboxApiAccessToken={process.env.REACT_APP_MAPBOX_TOKEN}
onViewportChange={(viewport) => {
this.props.updateViewport(viewport);
}}
>
Is there a setting in Prettier that overlooks the alignment formatting? Alternatively, is there a different way of doing this?
Pls check the Ignoring Code function of Prettier.
Basically, just add comment prettier-ignore before the code to which you applied Better Align and which you want to prevent Prettier from formatting when saving the file.
A JavaScript comment of // prettier-ignore will exclude the next node
in the abstract syntax tree from formatting.
For example:
matrix(
1, 0, 0,
0, 1, 0,
0, 0, 1
)
// prettier-ignore
matrix(
1, 0, 0,
0, 1, 0,
0, 0, 1
)
will be transformed to:
matrix(1, 0, 0, 0, 1, 0, 0, 0, 1);
// prettier-ignore
matrix(
1, 0, 0,
0, 1, 0,
0, 0, 1
)
The only way I can think of is disabling formatOnSave and leaving the alignment for after formatting, I'm afraid.
I am trying to use an alppha mask filter to apply a texture to a canvas element but cannot seem to get things to work. I have a base image which is a flat white color and to which I want to apply a color filter at runtime based on a users selection for example:
bitmap = new createjs.Bitmap(image);
bitmap.filters = [
new createjs.ColorFilter(0,0, 0.5, 1, 0, 0, 120, 0)
];
bitmap.cache(0, 0, 500, 500, 2);
I then want to use a second image which is a texture png that will add various shading texture to that first one. Looking over the docs it would seem that I need to use an AlphaMaskFilter but that does not seem to work and nothing is rendered onto the canvas. For example:
//filterImage contains the transparent image which has a shaded texture
var bitmap2 = new createjs.Bitmap(filterImage);
bitmap2.cache(0, 0, 500, 500, 2);
var bitmap = new createjs.Bitmap(image);
bitmap.filters = [
new createjs.ColorFilter(0,0, 0.5, 1, 0, 0, 120, 0),
new createjs.AlphaMaskFilter(bitmap2.cacheCanvas)
];
bitmap.cache(0, 0, 500, 500, 2);
Can someone help point me in the right direction here or if I am trying to do something which is just not possible using that filter.
I am very new to programming so please excuse me for not being very technical. Is there any way to make the following line of code produce a value so I can assign a name to it?
Dim myGraphics as Graphics = Me.CreateGraphics
myGraphics.FillRectangle(myBrush, 0, 0, 300, 10)
for example I would want the code to be
topWall = myGraphics.FillRectangle(myBrush, 0 , 0, 300, 10)
I know I could use a rectangle instead for this but I was just looking to know if there is a way to do this. I hope this makes sense. I appreciate your help!
I am trying to have two panels, the left showing a graphic and two locators, the right one a zoomed-in version in the area defined by the locators.
I've tried
ClearAll[mndpt];
mndpt = Compile[{{c, _Complex}, {maxiter, _Integer}},
Module[{z, iters},
iters = 0.;
z = c;
While[(iters < maxiter) && (Abs#z < 2),
iters++;
z = z^2 + c];
Sqrt[iters/maxiter]],
{{z, _Complex}},
CompilationTarget \[Rule] "C",
RuntimeOptions \[Rule] "Speed"];
and do
Manipulate[
Grid[
{{DensityPlot[mndpt[x + y*I, 200],
{x, -2, 1}, {y, -1.5, 1.5},
PlotRange \[Rule] {0, 1}, PlotPoints \[Rule] 80,
ColorFunction \[Rule] "Rainbow"],
DensityPlot[mndpt[x + y*I, 200],
Dynamic#{x, p1[[1]], p2[[1]]}, Dynamic#{y, p1[[2]], p2[[2]]},
PlotRange \[Rule] {0, 1}, PlotPoints \[Rule] 80,
ColorFunction \[Rule] "Rainbow"]}}],
{{p1, {-1, -1}}, Locator}, {{p2, {0, 1}}, Locator}]
The right panel does not then work:
My question is, why is this so? As you can see, it complains that "DensityPlot::pllim: Range specification {x,-1,0} is not of the form {x, xmin, xmax}. " which I find puzzling. In fact I am generally puzzled. What is going on? Some sort of scoping issue? Evaluation issue? And how can I get it to work? This is probably simple, but I never really understood this frontend stuff.
EDIT: It turns out that this question was due to a (hopefully momentary) sharp increase in stupidity on my part. As pointed out by Simon in a comment, removing the two Dynamics
(which I had added in a blind effort to make this work) makes everything work fine. That is,
Manipulate[
Grid[
{{DensityPlot[mndpt[x + y*I, 200],
{x, -2, 1}, {y, -1.5, 1.5},
PlotRange \[Rule] {0, 1}, PlotPoints \[Rule] 80,
ColorFunction \[Rule] "Rainbow"],
DensityPlot[mndpt[x + y*I, 200],
{x, p1[[1]], p2[[1]]},{y, p1[[2]], p2[[2]]},
PlotRange \[Rule] {0, 1}, PlotPoints \[Rule] 80,
ColorFunction \[Rule] "Rainbow"]}}],
{{p1, {-1, -1}}, Locator}, {{p2, {0, 1}}, Locator}]
does the right thing:
So, who knows why else I did the first few times so that it didn't work.
On the other hand, the message in the original case, namely, "DensityPlot::pllim: Range specification {x,-1,0} is not of the form {x, xmin, xmax}. " was more puzzling. I think it's been explained by Leonid, also in a comment (in brief, try ClearAttributes[Dynamic, ReadProtected] then ??Dynamic and you can see that there is a definition Dynamic/:MakeBoxes[BoxForm`x$_Dynamic,StandardForm]:= etc). As my understanding of frontend programming is negligible I won't try to explain it here, so if anybody does post an answer explaining that, it would be appreciated.
As discussed in the comments to the question, the code works fine if the Dynamics are removed from the ranges in the second DensityPlot. The Dynamics are not normally needed in the body of a Manipulate as it is automatically wrapped in a dynamic construct. Although, for a more fine grained control of which parts of an expression update, it can be useful to use Dynamic inside of a Manipulate.
The reason an error was created was because the range of a plot should be of the form {x, xmin, xmax} with x a Symbol and xmin and xmax numeric. Wrapping Dynamic around the list changes the head and breaks the plot.
The reason that the error was not obvious to spot is because the error message was a little confusing:
Range specification {x,-1,0} is not of the form {x, xmin, xmax}.
Which, on the surface looks crazy, but makes sense once you realise (as pointed out by Leonid) that Dynamic is a wrapper that has a MakeBoxes definition that makes it invisible when outputted to the notebook. To see this, look at
In[1]:= FormatValues[Dynamic]
Out[1]= {HoldPattern[MakeBoxes[BoxForm`x$_Dynamic, StandardForm]] :> (DynamicModule;
DynamicDump`ControlToBoxes[BoxForm`x$, StandardForm]),
<<snip: same but for TraditionalForm>>}
and ControlToBoxes in turn, creates a DynamicBox object. This can also be seen by entering Dynamic[x] and using the cell menu or shortcut to Show Expression of the produced output cell - you can also look at the underlying expression of the error message and see the DynamicBox construction there. It's also possible to Unprotect and remove the MakeBoxes definition of Dynamic, but that breaks most of the dynamic functionality in Mathematica...
Finally, here's my version of the code:
mndpt = Compile[{{c, _Complex}, {maxiter, _Integer}},
Module[{z = c, iters = 0.0},
While[(iters < maxiter) && (Abs#z < 2), iters++; z = z^2 + c];
Sqrt[iters/maxiter]], CompilationTarget -> "C",
RuntimeOptions -> "Speed"];
opts = Sequence[PlotPoints -> 80, ColorFunction -> "Rainbow",
ImageSize -> Medium, ImagePadding -> {{30, 5}, {20, 5}}];
fixed = DensityPlot[mndpt[x + y*I, 200], {x, -2, 1}, {y, -1.5, 1.5},
PlotPoints -> 120, Evaluate[opts]];
Manipulate[Grid[{{fixed, DensityPlot[mndpt[x + y*I, 200],
{x, p[[1, 1]], p[[2, 1]]}, {y, p[[1, 2]], p[[2, 2]]}, Evaluate[opts]]}}],
{{p, {{-1, -1}, {0, 1}}}, Locator, ContinuousAction -> False}]
