[Scilab-users] ?==?utf-8?q? Exporting graphic figure and its calcs

[Philipp Mühlmann]

Hallo,
I understand you want to export a GUI-surface with all entities (buttons,
etc) as an image.

For windows machines one can use the dos() command, connected with
irfanView to create screen shots and save them as an image.

Have a look at the irfanView i_options.txt to see what can be done by
calling irfanView.

Here an example:
you might exchange the path-variables to your needs


h = figure('position', [50 50 400 400], 'backgroundcolor', [0.7 0.9
1], .."figure_name", 'WHAT DAY WERE YOU BORN?');
T1 = uicontrol(h, 'style', 'text', 'string', 'Type year:',
..'position', [20 340 200 50], 'backgroundcolor', [0.7 0.9 1]);
E1 = uicontrol(h, 'style', 'edit', 'string', '2000', ..'position',
[150 350 70 30], 'fontsize', 15, 'backgroundcolor', [1 1 1]);
T2 = uicontrol(h, 'style', 'text', 'string', 'Select month:',
..'position', [20 260 200 50], 'backgroundcolor', [0.7 0.9 1]);
L1 = uicontrol(h, 'style', 'listbox', 'position', [150 130 120 170], ..
 'fontsize', 15, 'backgroundcolor', [1 1 1]);set(L1, 'string',
'January | February | March | April | May | June | ..July | August |
September | October | November | December'); set(L1, 'value', [1:12]);
T3 = uicontrol(h, 'style', 'text', 'string', 'Type date:',
..'position', [20 60 200 50], 'backgroundcolor', [0.7 0.9 1]);
E2 = uicontrol(h, 'style', 'edit', 'string', '15', ..'position', [150
70 70 30], 'fontsize', 15, 'backgroundcolor', [1 1 1]);
function birthday(guientries)
       y = eval(get(E1, 'string'))
       m = get(L1, 'value')
       d = eval(get(E2, 'string'))
    num = datenum(y, m, d);
    [n, s] = weekday(num);
    disp('You were born on '+s)endfunction
P1 = uicontrol(h, 'position', [300 70 80 30], 'style', 'pushbutton',
..'string', 'Submit', 'callback', 'birthday', 'backgroundcolor', [1 1
0]);
// access IrfanView and try to make a screen shot of the GUIIV_PATH =
'C:\Program Files (x86)\IrfanView';
OUT_PATH = 'E:\Scilab_Uebungen\031_call_software'
// capture the GUI crop it, so that figure borders are not visible
anymore and save it as a png filedos('i_view32.exe /capture=3
/crop=(0,47,0,420,0) /convert='+OUT_PATH+'\test.png ');



Good luck,
Philipp
