[Octave-bug-tracker] [bug #55999] Display images larger than GL_MAX_TEXTURE_SIZE

[Charles Praplan]

Follow-up Comment #16, bug #55999 (project octave):

Thank you for your help.

The first method you propose works correctly, also to save images (I tried png
and jpg). The saved files correspond to the figure.


However to get a correct output, the size of the figure must be restored
before printing, using


set(gcf, 'Position', [x0 y0 w0 h0])


The reason why the size of the picture changed is illustrated by the 2
appended figures, obtained executing following code from an m-file (not step
by step).
The difference between the 2 pictures is a small delay generated with
pause(0).


x0=200; y0=45; w0=1305; h0=round(w0/sqrt(2));


fig2=figure;
set(gcf, 'Position', [x0 y0 w0 h0]);
subplot('Position',subplot1_pos);
subplot('Position',subplot2_pos);
subplot('Position',subplot3_pos);
subplot('Position',subplot4_pos);

fig3=figure;
pause(0)
set(gcf, 'Position', [x0 y0 w0 h0]);
subplot('Position',subplot1_pos);
subplot('Position',subplot2_pos);
subplot('Position',subplot3_pos);
subplot('Position',subplot4_pos);


Then, executing following code reduces the size of fig2.


figure(fig2)
annotation('textbox', [0.01, 0.01, 0.5, 0.057], 'String', 'Annotation')
figure(fig3)
annotation('textbox', [0.01, 0.01, 0.5, 0.057], 'String', 'Annotation')


I fully agree that this is outside the scope of this report.

Should I post a report for this delay problem?
