Filling Masks
To fill closed mask outlines:
Although a mask outline appears to be closed, it may actually have one
or several gaps. When filled, such outlines ‘leak’ and allow the mask color
to cover also other image areas or even the entire image.
This situation may e.g. occur if ...
• 8-bit masks are painted with a blurred brush border, above all if
GAUSS is used. To prevent mask leaking in this case you should
paint the mask outline twice.
• a mask created on an image displayed with high resolution is filled
on an image displayed with lower resolution (‘coarse image’) since
the mask becomes coarse in this case. See also page 20-8.
If a mask leaks, select UNDO 1 FILL in the MENU window to reverse the fill
operation. Then close the gap in the outline. If you have filled several arhttp://www.image2output.com
Creating Masks and Cut-outs
Creating Pixel Masks Using Brush
1. Select FILL in the MENU window of the MASKS | PIXEL function. This
enables the FILL mode.
2. Click anywhere inside a mask outline to be filled.
In case of 8-bit masks, closed outlines are formed by mask areas with
a higher density than the current mask density (selected in the dialog).
When you click inside such an outline, it is filled with mask color
of the current density.
Note:
There is a tolerance of 2%, i.e., mask areas form a closed outline
even if their density is 2% lower than the current mask density.
3. Repeat step 2 until you have filled all areas you want to cut out.
4. You can use UNDO 1 FILL and UNDO ALL FILLS in the MENU window to
reverse the first or all fill operations respectively.
5. To resume manual masking, select POINT or LINE in the MENU window.
This disables the FILL mode.
Tip:
Typically, you move the cursor along the outline of the area to be cut out
and fill it afterwards. It is often a good idea to draw the line outside this
area, fill the image area you do not need and finally invert the mask.
