  Gabor transform is one of the performed tools for time-frequency signal
analysis. The principal aim of this paper is to generalize the Gabor Fourier
transform to the quaternion linear canonical transform. Actually, this
transform gives us more flexibility to studied nonstationary and local signals
associated with the quaternion linear canonical transform. Some useful
properties are derived, such as Plancherel and inversion formulas. And we prove
some uncertainty principles: those including Heisenberg's, Lieb's and
logarithmic inequalities. We finish by analogs of concentration and Benedick's
type theorems.
