I have a filter that works fine with a plate but as soon as run it with
anything with a bounding box inside the image bounds I get an instant
crash. I've tried this with rotoshapes and just cropping a the plate down.
I can only assume I'm trying to access some info that is outside the
bounding box but I'm not sure where. I've tried the following two
methods in _validate() both with the same (crashing) result. I get no
output from the console after the crash.
copy_info();
info_.y(info_.y() - sizeY);
info_.t(info_.t() + sizeY);
info_.x(info_.x() - sizeX);
info_.r(info_.r() + sizeX);
And,
copy_info();
info_.pad(std::max(sizeX, sizeY));
And then I'm requesting the following.
input(0)->request( x - sizeX , y - sizeY , r + sizeX, t + sizeY,
channels, count );
And this should give me the enough pixels at the bounding box to process
my filter, where sizeX is an integer value rounded up from the width of
my filter.
I know this is a little vague, but any ideas what is going wrong. As I
said it works correctly unless the bounding box is INSIDE the image bounds.
Cheers,
Steve
