[ferret_users] Limitation of gif pixel?

["Yu, Hao-Cheng" <danish.url@xxxxxxxxx>]

Dear ferret users,

 

I try to produce a high resolution gif file (say 1200*1200) with set_pixel_size.jnl script.

Some weird thing happen,

if I control size below 900, the actual pixel size will increase with setting, like 400*400 and 800*800,

the pixel size are about 382*382 and 756*756.

However, if I increase size above to 900*900 (or 1200*1200),

the actual pixel size of gif is all the same (about 856*856) with above to 900*900 setting.

 

The gif is produced with ferret normal mode, and I can see the window size increase until about 900*900.

Could this problem cause by monitor resolution or graphic card limitation?

 

Regards, dan
