Acquiring Images
You can acquire images for Corel
Painter directly from an external
device—such as a scanner or digital
camera—if the device provides a:
• Photoshop-compatible plug-in
module (Mac OS)
• TWAIN driver (Windows)
Before acquiring images:
• Install the device plug-in module
on your computer.
This plug-in module is provided
by the manufacturer of your
scanner or digital camera. Refer to
the device documentation for
installation instructions.
Corel Painter can access plug-ins
from any single folder on your
computer. This location can be
inside the Corel Painter folder, in a
generic plug-ins folder on your
hard drive, or in the Photoshop
Plug-Ins folder.
• Make sure your TWAIN driver is
properly installed.
Understanding Resolution
When working with images in a
digital workspace, it is helpful to
understand the concept and
applications of resolution. Resolution
refers to how Corel Painter measures,
displays, saves, and prints images—
either as small squares of color known
as pixels or as mathematical objects
known as vectors.
A document’s resolution affects both
its appearance on your computer
screen and its print quality. You can
specify a document’s resolution when
you create a new document, acquire
an image, and save/export a file.
Resolution and Screen
Appearance
Most monitors have a resolution of 72
dpi (dots per inch). Because of this,
the Corel Painter display default is 72
ppi (pixels per inch). This means that
each pixel in the Corel Painter image
occupies one pixel on your monitor.
The display resolution does not affect
the document’s actual ppi—only how
the image is displayed on the monitor.
For example, a 300 ppi document
displays at approximately four times
its actual size. This happens because
each pixel in the Corel Painter image
occupies one pixel on your monitor,
and the monitor’s pixels are four times
the size of the image’s pixels. Put
another way, at 300 pixels per inch,
your document will be approximately
a quarter of its on-screen size when
printed. In this example, if you want
to view the image at actual size, set the
zoom level to 25%.
Keep in mind that if you leave the
dimensions in pixels and then change
the pixels per inch (resolution), the
actual printed size will be affected by
the change. If you set your document
