Image Import Example

WHAT IS IT?

This code example shows how to use, and the differences between, the import-pcolors, import-drawing, and import-pcolors-rgb primitives.

Agents cannot sense the drawing, so they cannot interact with or process images imported by import-drawing. If you need an image agents can sense, you must use import-pcolors or import-pcolors-rgb.

HOW TO USE IT

Select the sample image you want to import with the FILENAME chooser, and then press either button below the chooser.

If you want to use your own image file, use the buttons that use user-choose-file to let you pick a file.

THINGS TO NOTICE

The drawing appears in front of the patch colors.

Images imported by import-pcolors and import-pcolors-rgb are scaled to fit the world. The colors when using import-pcolors may be distorted since NetLogo supports only a limited color set for pcolor values. When using import-pcolors-rgb the colors will be set to three-item RGB lists. See the Color section of the Programming Guide in the NetLogo User Manual for information on colors in NetLogo.

THINGS TO TRY

Try loading the different images into the patches to get an idea of the type of color distortion to expect.

Try importing an image with import-pcolors and then import the same image with import-drawing and import-pcolors-rgb. How does handling of the image differ?
