Rasterizing, merging raster images
Rasterizing Vector Data
You can rasterize vector objects on
raster images.
Select some vector objects (the vector objects must be
located over a raster image), and then start the Vector To Raster
command from the rConvert menu.

If you have more than one raster image
in your document, select the image(s) on which the rasterized vectors
should be placed.
Merging raster images
You can merge a raster image or raster
selection with another raster image.
Select a raster image (or its fragment)
and choose Merge or Merge a Copy from the
rEdit menu.
If part of the raster selection is placed
outside the boundary of the destination raster image area, it will disappear
when merged.
To perform this operation, first you should select
the source images. They are selected as AutoCAD objects. You can select
any type of raster image (color, greyscale or monochrome) as a source
image. A raster selection can also be used as a source image.
Next, you should select the destination image(s).
This selection is made from the selection dialog box.
If you have more than one raster image to merge
in your document, select the image(s) to merge.
When selecting destination images, WiseImage takes
into account the type of selected source images - the destination image(s)
must have a greater color depth than the source image(s): e.g. monochrome
into greyscale and color, greyscale into color (not into monochrome),
and color into color only. Those images that do not have a high enough
color depth are excluded from the list of selectable destination images.
Merging a Copy (i.e. duplication) works in a similar
way to merging except it does not erase the source image from the drawing.
To perform duplication you should perform the
same actions as when merging, except the command is called Merge a
Copy and the button looks like  .
Transforming Selection Set
into Separate Image
The detaching operation transforms a selection set into a separate image (or a group
of images, if a selection was made on several images) without changing
the position or size of the raster selection.
A selection set is always transformed into a separate
image if its position or size is changed.
In some cases it may be necessary to transform
a selection set into a separate image, without changing the position or
size of the raster selection. For example, it is necessary when layering
raster images, when the original image is divided into two images of the
same size, lying one above the other. The creation of raster layers
means it is possible to separate raster image objects of different types
onto separate layers as with vector objects in AutoCAD. For example, you
can select all raster texts and move them to a separate layer for extra
clarification.
To create a new image from a selection:
- Select some raster data.
- From the rEdit menu select Selection to New Image.

Click the button 
on the WiseImage toolbar.
