XObjHasInterpolate
An int value
that represents the number of interpolate entries found in the PDF document.
When the resolution of a source image is lower than the resolution
of the output device, each source sample covers many device pixels.
As a result, images can appear jaggy or blocky. These visual artifacts
can be reduced by applying an image interpolation algorithm during
rendering. Instead of painting all pixels covered by a source sample
with the same color, image interpolation attempts to produce a smooth
transition between adjacent sample values. Image interpolation is
enabled by setting the Interpolate entry in the image dictionary
to true.
