  We present images and slitless spectra which were obtained in HST surveys of
Planetary Nebulae (PNe) in both the Large and Small Magellanic Clouds, using
the Space Telescope Imaging Spectrograph. These new data on 59 PNe (54 in the
LMC and five in the SMC) permit us to determine the nebular dimensions and
morphology in the monochromatic light of several emission lines: Halpha, [N II]
lambda 6583 and [O III] lambda 5007, plus others of varying ionization,
including [O I], He I, and [S II]. We describe the nebular morphology and
related features in detail. This survey, when combined with similar data from
our prior HST programs and other archived PN images, brings the total of
nebulae imaged with HST to 114 in the LMC and 35 in the SMC. We describe
various basic properties for the sample, including sizes, morphologies,
densities, and completeness. Trends in [O III] lambda 5007 flux, surface
brightness, and electron density with physical radius suggest that many
nebulae, particularly those with bipolar morphology, may be optically thick
even at large size. Bipolars also show the most extreme values of [N II]/Halpha
flux ratios, which is a rough indicator N enrichment.
