Image Filter
|
Displays background images that
you resize. Set this to Point , Bilinear , or Trilinear . These are methods of
displaying your image on-screen. Use Point when the size of the image in the
display, for example,a 500 x 500 pixel image at 100% is the same 500 x 500
pixels on-screen. Use Bilinear or Trilinear when you display your image
on-screen using more or fewer pixels than your image contains, for example a
500 x 500 pixel image stretched to 800 x 800 pixels on-screen. Trilinear gives
you smoother transitions when you zoom in and out of the image.

Transparency
|
Set the transparency level of
the background layer. You can add transparency to any image type you use as a
background and it will ignore any transparency that exists in the image before
you use it as a background.
|
Resolution
|
Select the clarity for images
that are being used as background images.
|
Unit
|
Select the unit that should be
used.
|
Use Compression
|
If you check this option you
can compress the image in memory so that it takes up less RAM. When checked
there may be a slight color distortion in the image.
Note: The way the
image is compressed depends on your computer’s video card. Not all video cards
support this feature. If you check this option but your computer’s video card
does not support image compression, the request for compression will be ignored
and the image will be loaded uncompressed.

Optional Image Loading Mode
|
Optimal image loading mode
takes advantage of modern graphics cars which support OpenGL 3.0 or greater.
This mode will deliver faster performance and consume less system memory while
loading raster image background files.
For systems
which do not support OpenGL 3, we recommend turning this option off. This may
often be the case in virtual machine enviroments.
Note: Optimal image loading mode has an image size constraint due
to the capacity of the graphics cards texture memory. Most modern graphics card
can support images with a dimension up to 8,000 pixels, some newer cards have a
larger capacity. If we detect the image is larger than the texture memory
constraint, we will load the image using compatibility mode which will result
in degraded performance. For peak performance, we recommend splitting up images
larger that 8,000 pixels into multiple smaller tiles and loading them
individually.

Image Position Table
|
Position the background layer
with respect to your drawing. X/Y Image displays the size of the image you are
using for a background and sets its position with respect to the origin of your
drawing. You cannot change this data. X/Y Drawing displays where the corners of
the image your are using will be positioned relative to your drawing. By
default, no scaling is used. However, you can scale the image you are using by
setting different locations for the corners of the image you are importing. The
locations you set are relative to the origin of your
HAMMER
CONNECT drawing.
