This \{ \ts b \ts b will KILL \} the primary buffer. If you have not saved
your work, it \{ \ts i will be lost\} .
Once you have deleted the current primary, \{ \ts b Imagemaster R/t \} will
allow you to choose another primary buffer - if you had more than one buffer
loaded.
If you have no other buffers loaded, a selection menu will not be provided.

\title "Kill other Buffer"
\next "mb_newbuffer"

Using this will give you the option to KILL any buffer, except the primary.
Remember that if you have not saved, any changes \{ \ts i will be lost\} .

The New Buffer panel gives you the oportunity to create a new buffer.
The new buffer can either be created empty (black, or set to a custom color)
at a custom size, or it can be automatically filled with grey level
information generated by the blend (alpha channel) functions.

This allows you to choose the primary buffer from the current buffers that
are loaded into memory within \{ \ts b Imagemaster R/t\} .
Depending on the setting of the \ts bi Graphic Buffer List \ts n control in
the \ts bi SetUp \ts n panel, you will either be presented with a scrolling
list of named buffers, or a page of images and names.
Either way, click on the buffer that you want to become the primary buffer.

This allows you to choose the secondary buffer from the currently loaded
buffers. The secondary buffer is necessary for all operations in the
\{ \ts ib Compose \} panel.
Depending on the setting of the \ts bi Graphic Buffer List \ts n control in
the \ts bi SetUp \ts n panel, you will either be presented with a scrolling

\node "mb_useundo"
\title "Use Undo Buffer"
\next "mb_renamebuffer"
\prev "mb_selblendctrl"
The undo buffer is an extremely important feature in \{ \ts b Imagemaster
R/t\} . It is important to note that an undo buffer for a 24 bit RGB image
will require as much memory as the original image, unless the original image
also has a mask (masks are not maintained in the undo buffer). If the \ts bi
Use Undo \ts n control is selected \{ \ts b Imagemaster R/t \} will always
try to use the undo buffer.
It is also important to note that a number of processes require the use of
the undo buffer. This is because the undo buffer is used as a reference for
the process which is taking place in the primary image. If an operation
requires an undo buffer \{ \ts b Imagemaster R/t \} will tell you if an undo
buffer has not been allocated.
Memory constraints are a concern for most users, and this situation is even
further complicated by the use of an undo buffer. As previously stated the
undo buffer will use the same amount of memory as the primary image. A
solution to this "memory shortage" is to clip out the region you are working
on. After clipping out the area you wish to work on, click on the undo
buffer. Since this is a much smaller image than the original the memory
requirements are much less. You can then use the \{ \ts b \ts i Restore to
Src Buffer \} button to replace the altered clip back to the original image.
By doing this you have avoided using the large amounts of memory that the
entire primary image would have required.

\node "mb_renamebuffer"
\title "Rename Buffer"
\next "mb_restoretosrc"
\prev "mb_useundo"
This operartion will allow you to rename any active image buffer, excluding
the \{ \ts b \ts i Undo Buffer\} . Buffers may have the same name, but it
is not wise to do this. \{ \ts b Imagmaster R/t \} will not confuse two
buffers with the same name, but you might!
Depending on the setting of the \ts bi Graphic Buffer List \ts n control in
the \ts bi SetUp \ts n panel, you will either be presented with a scrolling
list of named buffers, or a page of images and names.
Either way, click on the buffer that you want to become the primary buffer.

This allows you to replace a clipped out region exactly back to the area it
was clipped from in the primary image.
There is one restriction, the image that you will be clipping back to must
remain in active memory. A reloaded image \{ \ts i will not work\} .
This operation is the key to working on portions of your images with a level
of isolation (safety) that is very useful. Since this allows you to place a
clipped region back into the image it was clipped from \ts i exactly\ts n ,
you can easily perform the following steps:
\{ \nw
\ts b ( 1) \ts n Clip a subregion, such as a face from a body as the new primary
\ts b ( 2) \ts n Process that region to your heart's content
\ts b (3a) \ts n Either discard it and make the original primary (lose changes)...
\ts b (3b) \ts n ...or restore it, changing the original image.\}
This type of operation is an excellent way to work on small areas of an
image. If you are short on memory, it can also allow you to use the undo
buffer in situations that would otherwise be impossible. Since a clipped
region takes so much less memory than a complete buffer, even the demands of
both the new clip \ts i and \ts n the memory for an undo buffer that matches
it's size are much, much less than that of an undo buffer for the entire
original image.
Because of this, you can turn the undo buffer on when you're working on the
clip and have the convenience of being able to eliminate the most recent step
of your work.

Pressing the \ts bi S \ts n key will also execute this operation.

to the original buffer by pressing this button again.

\title "Unlock a Buffer"
\next "mb_setaspectdpi"
\prev "mb_swapcurrent&sec"
Unlocking buffers is a way for a user to unlock a buffer which may have been
locked by a PI module or other external application which has been sharing
buffer memory with \{ \ts b Imagemaster R/t\} .
This is rarely required, and in most cases, the normal user will not need it.
However, when you are developing PI Modules, it can be very useful.
Unlocking a buffer has its consequences. If the buffer is still being
accessed by an external process and you unlock it, the buffer can be
manually deleted, or the user may even exit and delete all buffers.
After all of this, the task which was writing to the buffer will now be
writing to what the system has listed as free memory. This button will warn
the user that manual unlocking is \{ \ts i not \} normally advised.

\node "mb_setaspectdpi"
\title "Set Current Aspect and DPI"
\next "mb_cat"
\prev "mb_unlockbuffer"
This button allows you to customize each image to your display, and to change
the aspect ratio. If you save your image after changing its aspect it will
retain that aspect the next time it is loaded, not the original aspect.
\{ \ts b \tc DarkBlue How To determine Aspect Ratios\}
\{ \ra \image "Clips/Bullet2.pic" l 10 \cap
First, the size of the desired output area (screen, output paper, etc) must
be measured for length and height.\}
\{ \ra \image "Clips/Bullet2.pic" l 10 \cap
Next, the pixel width is determined by dividing the width of the output
device by the number of pixels. For example, 320 pixels is aproximatly 10.5
inches on our 1084 monitor. The pixel width would be: (10.5/320) = .033
inches/pixel horizontally.\}
\{ \ra \image "Clips/Bullet2.pic" l 10 \cap
The same process would be used to determine the height. For example, we
found that in non-interlace mode the displayed region was 8 inches. The
pixel height would be: (8.0)/200) = .04 inches vertically. \}
\{ \ra \image "Clips/Bullet2.pic" l 10 \cap
The aspect ratio can now be calculated. For example, using the previous
values: (.033/.04)100 = 83%. This process can be repeated for any number of
resolutions.\}

This selection will add the current primary buffer to the catalog. You will
only need to use this function if you have the \{ \ts bi Auto Catalog \}
button, in the \{ \ts bi Setup \} panel, turned off. If Auto Catalog is
selected, all images that are loaded will automatically be added to the
current catalog.

\title "Edit Image Annotation"
\next ""
\prev "mb_cat"
This selection allows you to edit any text notes that have been saved with an
image. Imagemaster has two formats which support annotation - IFF and TRIM.
The annotation will only be saved with the image if one of these two formats
is the selected \{ \ts b Save Type\} . Pressing this button will bring the
Amiga text editor \{ \ts b ED \} to the front. If the current primary image
has any associated annotation it will automatically appear in the editor.
You can then enter the desired annotation to be saved with the image file.
After you have finished your annotation, press the escape key and then the
\{ \ts b s \} and \{ \ts b a \} keys, followed by the Return key. This will
save the annotation to a temporary file in ram. You can exit ED by pressing
escape, q, and then Return keys. The annotation file will be saved to the
image file when the image is saved. If you do not save the image before
exiting R/t, the annotation will be lost.
