try to create an image with a custom buffer, format rbga
|
||
|
|
image is 278x57
|
||
|
|
got 63384 bytes, need 63840 bytes
|
||
|
|
63384=278*57*4, checks out. why 63840?
|
||
|
|
factor 63384=2*2*2*3*19*139
|
||
|
|
factor 63840=2*2*2*2*2*3*5*7*19
|
||
|
|
factor 278=2*139
|
||
|
|
factor 57=3*19
|
||
|
|
factor 4=2*2
|
||
|
|
63840 doesn't have 139 as a factor... if we divide by the other two we get 2*2*2*5*7=280
|
||
|
|
is it padding an extra pixel on each side? no, reducing video frame width to 276 still demands 63840 bytes.
|
||
|
|
does stretching image to 280 work? yes! so it has to be a multiple of 5... or 10, or 20. and larger than the requested dimension.
|

|
|
after some further fiddling, it's 8.
