Using Filter Layers
Notes on Pixelation Filter Layers
All other layer types (tints, gradients, texts, other filters) are replaced
by the new filter layer.
3. The respective image editing function starts. Refer to the pages indicated
above for more details.
4. If the filter layer seems to have no effect, it may be located below the
layers you are modifying. In this case you have to move the filter layer
up to the top.
Refer to Changing Stacking Order (page 16-15) for more details.
Notes on Pixelation Filter Layers
To calculate an image pixel, the program has to access also the neighboring
pixels. As a result, pixelations may look different with different
magnification levels (zoom factors) and the result on the printed page
varies according to the output resolution.
If an exact visualization of the final pixelation result is essential for you,
we recommend to apply the pixelation filter to the image itself (see
page 28-3).
Pixelation filters may require a large amount of memory when converting
pages to another format (FILE | EXPORT function), depending on the layout
size and output resolution. The conversion process may fail in case
of insufficient memory.
