is there an easy way to calculate offset in pixels for a specific angle ?

for example, i want to offset an object by 135°
how much is that in pixels in the offset dialogue (Strg +O) ?

90 and 180° are pretty obivious, how about other angles ?

I would use the Measurement tool




and then offset

If you are moving your object a distance D at an angle A then the you compute the x and y offsets with the following formula:

x = D * cos(A)
y = D * sin(A)

Where 'cos' and 'sin' are the mathematical cosine and sine functions respectively.

If you are writing a script or plug-in, you should be aware that the angle provided to the 'cos' and 'sin' functions are typically specified in radians, rather than degrees. To convert between radians and degrees, the following equation applies:

1 radian = 180 / π degrees
or
1 radian ≈ 57.3 degrees

thank you guys, will check that out later
