====== Export ======

CGRAPH supports two types of export:


  -Data can be saved as a CSV file and is then available outside the programme for further processing. Within CGRAPH, all CSV files created can also be re-imported into Linear Algebra for [[LinearAlgebra2D|2D]] and [[LineareAlgebra3D|3D]]. 
  -Graphics can be saved in various formats.

===== Exporting data =====

The Export menu item triggers different functions depending on what is currently displayed. If a graphic is displayed, it opens the dialogue box for exporting the graphic. If a default page is displayed, it opens a dialogue box for exporting the data to CSV. For graphic types that display graphics and default values in the same window, it opens the dialogue box for exporting the graphic. The data can be exported there using the {{symbol:export.png?16x16}} button.


===== Exporting graphics =====

CGRAPH can not only print graphics, but also export them in high resolution. This function is only available via the [[menu|menu]] //File/Export// on macOS or //File/Export// on Windows.

Graphics can be saved in various quality levels and formats. The following //bitmap sizes// are available:

  - Screen quality (75 dpi) - here, the graphic will look exactly as it does in the graphics window and will also be exactly the same size as the graphics window.
  - Low print resolution (150 dpi) - here the graphic is twice the width and height of the graphic window, i.e. four times the size.
  - Medium print resolution (300 dpi) - here the graphic is four times the width and height of the graphic window, i.e. 16 times the size.
  - High print resolution (600 dpi) - here the graphic is 8 times the width and height of the graphic window, i.e. 64 times the size.

The //format// can be selected from the following options:

  -BMP-Windows bitmap format: lossless and uncompressed, but requires a lot of storage space 
  -JPEG format: lossy and compressed, very small storage space requirement
  -PNG format: lossless and compressed, medium storage space requirement

You can also specify whether the set //background and axis colours should be ignored//. If this field is selected, CGRAPH will instead create an export graphic with a white background and colour the axes, markers and labels black and the background grid grey to match. The colours of the graphics are retained in all cases.

Finally, the directory and file name can be specified. If the graph type comprises several graphs (e.g. for [[frequency response|frequency responses]] or [[complex plane|figures in the complex plane]]), all of them are exported as separate bitmaps.
