Re: [swtchart-dev] GSoC 2020:Creating bitmaps with no restriction on res

    Hi Yash,
    
    the R script export works fine. Improvements are needed, when line
    series are added without lines (only dots). These are displayed as
    connected lines in the script. Moreover, the bar chart export option
    needs to be added.
    
    
    Best,
    Philip

Hi,

Also about Extending the R-Script Export ,

What all options need Improvement?

I found out these are general problems encountered when exporting plots as R-Script-

• Anti-aliasing is not activated in Windows R (this does not apply to Linux or Mac)
• When increasing the resolution the labels automatically decrease and become unreadable                                                                                       

One way to make the labels readable is to add additional inbuilt R function svg()

in the RScriptExportHandler Class.

for e.g.-

svg(filename="Std_SVG.svg", 
    width=5, 
    height=4, 
    pointsize=12)

Hi Yash,

yep, I would like to enable this in 2 steps:

1) Add the *.svg template export, so that people can export the chart to various formats via Inkscape.
2) If exporting the template works fine, we could try to include the advanced export option via SVG.


Best,
Philip

Hi,

When creating bitmaps the main problem when changing resolution of the *.bmp file is that it loses its quality because of which datasets are not visible .

Is it possible that first we create .svg file of desired resolution and then convert it into .bmp in this way quality of display  is preserved.

One way to convert to .bmp would be as follows:

  Bitmap.Config conf = Bitmap.Config.ARGB_8888; 
          Bitmap bitmap = Bitmap.createBitmap(50, 50, conf);

          // Get a Canvas for the Bitmap
          Canvas  canvas = new Canvas(bitmap);

          // Read the SVG file
          SVG svg = SVGParser.getSVGFromInputStream(inputstream);
          // There are other ways to read an SVG file. See the SVGParser class for the others.

          // Get a Picture from the SVG and render it to the Canvas
          canvas.drawPicture(SVG.getPicture());
