Re: [ferret_users] quality of gif/png images

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Yadu,
The file type written by the FRAME command is HDF if you don't explicitly give a format type.  It will be a GIF image if you give a filename that ends in .gif, or if you specify /FORMAT=gif.  so if you want a gif image you should say

yes? frame/file=file_name.png/format=gif

Another alternative to look at is to start Ferret in gif mode, which writes the gif image file directly, without an x-window.

> ferret -gif

yes? ! Run your graphics commands
yes? frame/file=file_name.png/format=gif

Dear ferreters,

I am using the -gif option to create gif/png images, and use

frame/file=file_name.png

When I do this the shaded images are fine but the quality of plotted lines is very poor and the lines get distorted when I print or copy them to word file.
Can anybody help me to get improved quality images. 

Is there anything in ferret to control or set the dot per inches (dpi) of the images.

Thanks in advance.
