Png Image GenerationPng Image Generation

Png_width = 400, Png_height = 400The image pane is square. Width is the

reference dimension; height includes additional 'real estate' for the color bar and logo bar. Thus, if both width and height are set, width is used to calculate the height. If only height is supplied, expect the width to be smaller than your height input.

'lx1', 'lx2' Creation Issues'lx1', 'lx2' Creation Issues

'lx1', 'lx2' directory structures are independent All ifpIMAGE configuration files are created via

the GFE on that machine. Output products go to data/products/IMAGE on

the machine it ran on. To see your output on either machine, redirect

your output to a common directory (e.g., a mounted NFS ds directory with the -o option)

ifpIMAGE uses, by default, the “SITE” configuration files.. If you log into the GFE as a user and create a config file, then run ifpIMAGE, no images will be generated. -u option overrides this

Tip…Tip…For ease of

modification and efficiency we recommend that you create a hierarchical configuration scheme for ifpIMAGE weather element configuration files.

Tip...Tip...To test your new ifpIMAGE configuration

file, run it from the GFE StartUp Menu. If it has been hidden, just type in the name.

This will help avoid unproductive ifpIMAGE script runs due to syntax errors in your configuration files.

If a syntax error is in your config file, a dialog will popup indicating the location of the problem.

Not everything can be tested from GFE, e.g., Png_parms.
