The image displayed as its complement is related to:

Probably there is a case where it missed the reset to normal, which
actually I just did not find in your code.
Thanks for hint (and for looking). I'll tackle this when the sizing issue
is solved but noticed that the complement only happens after an
indeterminate number of window resizings with the mouse drag.
This:
IupSetAttributes(IupFill(),"SIZE=5, EXPAND=NO"),
Can be reduced to:
IupSetAttributes(IupFill(),"SIZE=5"),
Because setting the size of a IupFill already has that effect. It is a
special control with a different behavior for size.
Ok, (I must have copied it from somewhere else).
I wouldn't recommend setting the size of the canvas inside it own
action callback. This could cause an infinite loop. You could load the
image, only once, some where else, then set the size and only redraw the
image on the action callback. im_view actually does exactly that, except
for the size.
I tried to use im_view as a guide but I couldn't find out where it sets
the window size so I came out with this solution. ... and as I referred
before, not easy do learn IUP without dedicated tutorials. I'll try to do
it the way you say.
Also changing the size of the dialog every time you load a new image can
have a very unpleasant effect on screen. Sometimes it is simpler to load
the image and redraw in the space you have available. But this is up to
you.
I'm trying to reproduce the Mirone behavior where that actually works
nicely (or so I think).

I think I have no EXPAND set to YES. The code, that crafted after
seeing for example the im_view example starts in
https://github.com/joa-quim/IUP.jl/blob/master/examples/mirone_toy_.jl#L40
later down, in function
https://github.com/joa-quim/IUP.jl/blob/master/examples/mirone_toy_.jl#L301
if I uncomment the line with
IupSetAttribute(handles.figure1, "RASTERSIZE", C_NULL)
than, not even it doesn't do any better as I can't even rescale the
window to a size larger than the loaded image.
There are a lot of other strange things that happen (like a random
conversion of the displayed image to its complement) that are difficult
to explain >>in a mail.
For instance, if it has the EXPAND attribute set to Yes. Or if the
dialog has a MINSIZE attribute set.
If you are not using EXPAND, or any other restriction on the dialog,
then setting size/rastersize should work.
It also depends if you set the size before or after the dialog is
shown.
So assuming that your dialog is resizeable, and EXPAND is not set,
nor there is no restrictions. Doing:
IupSetStrAttribute(iup_canvas, "RASTERSIZE", t); // notice that I
used "Str" since the t string is not static
IupRefresh(iup_canvas);
Should resize the canvas, although it will not resize the dialog. So
it can also resize the dialog, you should do:
IupSetStrAttribute(iup_canvas, "RASTERSIZE", t); // notice that I
used "Str" since the t string is not static
IupSetAttribute(iup_dialog, "RASTERSIZE", NULL) ;
IupRefresh(iup_canvas);

OK, I added a IupRefresh call but made no difference.
But if setting a control size depends on the control configuration
how can I set the size that I want?
In this case it refers to setting the control with the size of an
image being displayed on it.
Thanks
Joaquim
Hi,
Notice that set and get the RASTERSIZE of a control in IUP does
necessarily returns the same result. Depends a lot on the dialog and
the >>>>>control configuration.
If the dialog is already visible, then after setting the size you
should call IupRefresh so the dialog layout can be updated with the
new size.

Scuri

Hi,
I want to resize the figure window to the size of an image being
displayed
(not bigger than the screen ofc) but having (bad) surprises because
I get
something else than required.
For example, this piece of code clearly shows that the size
requested is
not being respected.
This is Julia code but understandable, I think
t = @sprintf("%dx%d", img.width, img.height)
@show(t)
IupSetAttribute(iup_canvas, "RASTERSIZE", t)
@show(bytestring(IupGetAttribute(iup_canvas, "RASTERSIZE")))
and the display is
t = "430x300"
bytestring(IupGetAttribute(iup_canvas,"RASTERSIZE")) = "414x168"
