  We apply the pixel method of analysis (sometimes called ``pixel lensing'') to
a small subset of the EROS-1 microlensing observations of the bar of the Large
Magellanic Cloud (LMC). The pixel method is designed to find microlensing
events of unresolved source stars and had heretofore been applied only to M31
where essentially all sources are unresolved. With our analysis optimised for
the detection of long-duration microlensing events due to 0.01-1 Mo Machos, we
detect no microlensing events and compute the corresponding detection
efficiencies. We show that the pixel method, applied to crowded fields, should
detect 10 to 20 times more microlensing events for M>0.05 Mo Machos compared to
a classical analysis of the same data which latter monitors only resolved
stars. In particular, we show that for a full halo of Machos in the mass range
0.1-0.5 Mo, a pixel analysis of the three-year EROS-1 data set covering
0.39deg^2 would yield ~4 events.
