How to build an images array? since I wanna put 90 frames buffer into 90 images, it’s stupid to declare 90 imges…
you can use a vector of ofImage to store your images :
Oh I see!!Thx
You can use
images.reserve(90); to create the array faster
but here is another problem…when build an images array, then I have to build the unsigned char*[ ] = img[ ].getPixels();
which cause a “thread_bad_access” to me
what do you mean by “build” an array ?
so let say you are using ofImage
declare an array
optionally reserve array space
copy your image to the array
thank you,but buffer is an array of unsigned char* …not ofImage…so how to pass it into the images[90 ]?
can you share the code ?
here is my code, I use an slitScan addon , but I just used the buffer** array in it…to draw every frame of buffer in my screen, could you tell me the way pass the buffer array to my image array?
src.zip (13.8 KB)
here is my code
when I run it,it can build succeeded but in ‘ofImage.cpp’there is an error"Thread 1:EXC_BAD_ACCESS’ imediately as below:
what are you trying to store in your array ? result of slitscan image process ? what does the image you are storing look like ?
yes I want to store the result of slitscan process buffer in my array, the images I’m storing are every frame of the slitScan.
even draw one image of array would cause the bad_access
but when i just use an ofImage instead of vector, it works without problem.
ok. I don’t know the slitscan addon, but you can grab an image from slitscan using getOutImage() which returns an ofImage.
so no need for a buffer, you can grab the processed image like so
// images is a vector of ofImage images.push_back(slitscan.getOutImage());
