front end - Default styles for Exporting to PDF, EPS and SVG


By default for on-screen display, Rasterize and Exporting to raster formats FrontEnd uses styles defined on the Notebook level via StyleDefinitions option:


SetOptions[EvaluationNotebook[], 

 StyleDefinitions -> 
  Notebook[{
    Cell[StyleData[StyleDefinitions -> "Default.nb"]], 
    Cell[StyleData["My"], FontColor -> Red, FontWeight -> Bold, FontSize -> 20, FontFamily -> "Times"]
   }, 
   StyleDefinitions -> "PrivateStylesheetFormatting.nb"]]

text = Style["Text", 20, "My"]
Rasterize[text]
ImportString[ExportString[text, "TIFF"], "TIFF"]

But local styles do not affect Exporting to vector graphics formats:


Export["temp.pdf", text] // SystemOpen
Export["temp.svg", text] // SystemOpen

What determines the styles used by default for Exporting to PDF, EPS and SVG? Is it possible to change the defaults?



Answer



According to the Documentation,



DefaultStyleDefinitions is a global option that specifies the default stylesheet for all new notebooks.



By spelunking Export with GeneralUtilities`PrintDefinitionsLocal


Needs["GeneralUtilities`"]

PrintDefinitionsLocal[Export]

one can find that for general expr Export first converts it into a Notebook using System`Convert`PDFDump`createVectorExportPacketExpr:


System`Convert`PDFDump`createVectorExportPacketExpr[expr]


Notebook[{Cell[BoxData["expr"], "Output", ShowCellBracket -> False, 
   CellMargins -> {{0, 0}, {0, 0}}]}]

As one can see, this Notebook has no StyleDefinitions option what means that it has to inherit it from the global DefaultStyleDefinitions.



Hence default stylesheet used by Export is determined by DefaultStyleDefinitions option of $FrontEndSession.



Changing the default stylesheet


At first in the user profile directory I create custom stylesheet "DefaultMy.nb" based on "Default.nb" but with an additional style named "My":


dir = FileNameJoin[{$UserBaseDirectory, "SystemFiles", "FrontEnd", "StyleSheets"}];
If[! DirectoryQ[dir], CreateDirectory[dir]];
Export[FileNameJoin[{dir, "DefaultMy.nb"}], 
 Notebook[{Cell[StyleData[StyleDefinitions -> "Default.nb"]], 
   Cell[StyleData["My"], FontColor -> Red, FontWeight -> Bold, FontSize -> 250, 
    FontVariations -> {"Underline" -> True}, FontFamily -> "Algerian"]}, 

  StyleDefinitions -> "PrivateStylesheetFormatting.nb"]]

Now I set it as the value for DefaultStyleDefinitions:


CurrentValue[$FrontEndSession, DefaultStyleDefinitions] = "DefaultMy.nb"

After evaluating this "DefaultMy.nb" will be immediately opened as a hidden Notebook what can be verified with the code provided by MB1965:


Cases[FrontEndExecute@FrontEnd`ObjectChildren@$FrontEnd, 
 obj_ /; StringMatchQ[WindowTitle /. AbsoluteOptions[obj, WindowTitle], 
    "Default" ~~ __] :> {obj, WindowTitle /. AbsoluteOptions[obj, WindowTitle]}]    



{{NotebookObject[FrontEndObject[LinkObject["ca2gp_shm", 3, 1]], 12], "DefaultMy.nb"}, 
 {NotebookObject[FrontEndObject[LinkObject["ca2gp_shm", 3, 1]], 4], "Default.nb"}}

If during current front end session there weren't invocations of Export to vector formats, this change will have immediate effect on Export. In the opposite case one should force FrontEnd to do something that will cause the style definition cascade to update: for example, an invocation of Export


ExportString["", "MGF"];

or "ToggleShowExpression" front end token (even when no Cell is selected)


FrontEndTokenExecute["ToggleShowExpression"]


does this. Other methods are discussed here.


Now


text = Style["Algerian", 50, "My"];
ImportString[ExportString[text, "PDF"], "PDF"][[1]]


output

plotting - Filling between two spheres in SphericalPlot3D

Manipulate[ SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, Mesh -> None, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], {n, 0, 1}] I cant' seem to be able to make a filling between two spheres. I've already tried the obvious Filling -> {1 -> {2}} but Mathematica doesn't seem to like that option. Is there any easy way around this or ... Answer There is no built-in filling in SphericalPlot3D . One option is to use ParametricPlot3D to draw the surfaces between the two shells: Manipulate[ Show[SphericalPlot3D[{1, 2 - n}, {θ, 0, Pi}, {ϕ, 0, 1.5 Pi}, PlotPoints -> 15, PlotRange -> {-2.2, 2.2}], ParametricPlot3D[{ r {Sin[t] Cos[1.5 Pi], Sin[t] Sin[1.5 Pi], Cos[t]}, r {Sin[t] Cos[0 Pi], Sin[t] Sin[0 Pi], Cos[t]}}, {r, 1, 2 - n}, {t, 0, Pi}, PlotStyle -> Yellow, Mesh -> {2, 15}]], {n, 0, 1}]

plotting - Plot 4D data with color as 4th dimension

I have a list of 4D data (x position, y position, amplitude, wavelength). I want to plot x, y, and amplitude on a 3D plot and have the color of the points correspond to the wavelength. I have seen many examples using functions to define color but my wavelength cannot be expressed by an analytic function. Is there a simple way to do this? Answer Here a another possible way to visualize 4D data: data = Flatten[Table[{x, y, x^2 + y^2, Sin[x - y]}, {x, -Pi, Pi,Pi/10}, {y,-Pi,Pi, Pi/10}], 1]; You can use the function Point along with VertexColors . Now the points are places using the first three elements and the color is determined by the fourth. In this case I used Hue, but you can use whatever you prefer. Graphics3D[ Point[data[[All, 1 ;; 3]], VertexColors -> Hue /@ data[[All, 4]]], Axes -> True, BoxRatios -> {1, 1, 1/GoldenRatio}]

plotting - Mathematica: 3D plot based on combined 2D graphs

I have several sigmoidal fits to 3 different datasets, with mean fit predictions plus the 95% confidence limits (not symmetrical around the mean) and the actual data. I would now like to show these different 2D plots projected in 3D as in but then using proper perspective. In the link here they give some solutions to combine the plots using isometric perspective, but I would like to use proper 3 point perspective. Any thoughts? Also any way to show the mean points per time point for each series plus or minus the standard error on the mean would be cool too, either using points+vertical bars, or using spheres plus tubes. Below are some test data and the fit function I am using. Note that I am working on a logit(proportion) scale and that the final vertical scale is Log10(percentage). (* some test data *) data = Table[Null, {i, 4}]; data[[1]] = {{1, -5.8}, {2, -5.4}, {3, -0.8}, {4, -0.2}, {5, 4.6}, {1, -6.4}, {2, -5.6}, {3, -0.7}, {4, 0.04}, {5, 1.0}, {1, -6.8}, {2, -4.7}, {3, -1.
