Export of Graphics to Files
Graphics is exported exactly the way you see it in the view area. Thus, all settings made in the View Preferences, your degree of zoom etc. will be reflected in the exported file. Furthermore, when saving in .png, .jpg, and .tif-formats you are prompted for which quality to save the graphics in.
Graphics can be exported into the following types of bitmap image files:
- Portable Network Graphics (.png)
- JPEG (.jpg)
- Tagged Image File (.tif)
In a bitmap image, each dot in the image has a specified color. This implies, that if you zoom in on the image there will not be enough dots, and if you zoom out there will be too many. In these cases the image viewer has to interpolate the colors to fit what is actually looked at. This format is a good choice for storing images without large shapes (e.g. dotplots).
Graphics can be exported into the following types of vector graphics files:
- Portable Document Format (.pdf)
- Scalable Vector Graphics (.svg)
- PostScript (.ps)
- Encapsulated PostScript (.eps)
Vector graphics is a collection of shapes. Thus what is stored is e.g. information about where a line starts and ends, and the color of the line and its width. This enables a given viewer to decide how to draw the line, no matter what the zoomfactor is, thereby always giving a correct image. This format is good for e.g. graphs and reports, but less usable for e.g. dotplots.
