Answer 1

saveas('figure.jpg')

The first input must be the handle of a figure.

print(gcf, 'figure.jpg', '-jpg', '-r600');

There is no '-jpeg' option for the print command. Do you mean '-djpeg' ?

Hi there,

thanks for the anwser . I tried this and I get an errror

Error using inputcheck
Illegal option '-jpg' given.

Error in inputcheck

Error in print (line 41)
[pj, devices, options ] = inputcheck( pj, inputargs{:} );

[Jan]

Okay. And with '-djpeg' ?

[Nikolas Spiliopoulos]

with -djpeg it's working, just wondering if there is any option for jpg

[DGM]

There is no '-djpg' device option. The option for JPG is '-djpeg'.

[Walter Roberson]

The "-d" prefix stands for "device". The output is to be sent to the JPG "device"

In print command, for jpg images, the flag is '-djpeg'
