PolarPaint v1.3 (r81) by Anbjørn Myren (anbjorn.myren@gmail.com)
This is an experimental Paint program made with Hollywood.
Requirements:
A fast computer with RTG, minimum 1440x900x16 (Program window 1385x820)
Minimum 40MB of free ram, 64MB or more recommended.
The small version require 800x600 (730x570) and needs 32MB ram.
More memory or diskspace might be desirable (read below for memory notes)
codesets.library 6.22+ and reqtools.library v39+
Versions for 68k, AmigaOS4, MorphOS and AROSx86 available
PDF manual is available as a separate download.
Functions in brief (not complete, look in the PolarPaint manual for more)
The painting area is 1280x720, 640x480 for the small version.
Up to 8 Workspaces can be used for separate drawings.
There is an Undo/Redo funtion. By default this is set to maximum 10 levels,
but can be set as high as 100. Each Workspace have its own Undo buffer, in
theory there might up to 800 undo's.
At program start Workplace 1 will be active. Click on one of the numbered
Workspace Tab's to use another workspace.
Animation features was added in r79 as well as Pixel like editing in zoommode
Memory notes
Each brush initiated will take about 4MB of memory. Opening a new workspace
consumes 4 MB per Workspace (unless diskbuffer is used).
The Undo / Redo system will also require memory since each Undo is a full
brush stored in memory.
If you set the Undo buffer to max (100) and use all 8 Workspaces you will in
theory have 800 undo operations available. Needless to say this will require
massive amounts of RAM available.
Diskbuffering
As a workaround for the memory issues mentioned above I made an optional
setting that allows you to enable DiskBuffering. This means that all Undo
buffering goes to your hardrive instead of using RAM. Also when opening a
new workspace the previous workspace is saved to disk and freed from memory.
By default these files are stored as PNG images which means they only take a
fraction of the space compared to the memory they would need.
The downside is that the undo/redo will be slower, because it needs to load
the files from disk and convert the png files into brush data.
If you suspect you might get short on memory, run the program first time and
press the Quit button, at the requestor select to Enable DiskBuffer before
quitting. Next time you launch the program diskbuffer will be enabled.
When DiskBuffer is active you will be asked on Exit if you want to keep the
buffer files. If you do so, they will be loaded automaticly on next start and
you can keep on working where you left off.
Help
There is an Information icon that will display some basic information about
the program, and while the icon is highlighted (info mode) the user can click
any icon to get some pop-up information about each button.
Click the info icon again to exit information mode.
Flood Fill
Regular floodfill is an in-built Hollywood command that works well in most
cases. But if you want to floodfill an area that has gradients of colors you
might experience that not all areas are filled as expected. An image saved
with JPEG compression will most likely have this issue.
To overcome this there is a custom fill command that uses a threshold setting
to determine how colors are filled. By default threshold is set to 0 and then
the in-built fill command us used. Setting threshold above 0 will make use of
the custom fill operation. The setting is quite sensitive so depending on
your image there could be a huge difference between 0 and 1.
You can use decimal values, eg. 0.01 or 0.5 so just try until satisfied.
The custom fill operation is much slower than the regular fill, specially on
low end computers. The way it works it will read the color form pixel by
pixel and create a table of pixels to fill.
For lower Threshold values it will process up to 1% of the image area before
filling, then process the next bacth until done.
For Threshold values 30% and higher the processing is much slower, so it
will then process only a user selectable area size all in one go.
Processing with high threshold will also consume memory.
As a general rule you need a system with 64MB RAM to process
sizes up to 5%, 128MB up to 50% and so on.
Use ESC to interupt an ongoing floodfill operation.
Transparency
There are two modes for transparency available. Default and Instant. The
default mode with process your whole line before applying transparency,
making it more smooth. The line will appear solid while the mouse is pressed.
The Instant mode will apply transparence as you draw, but will leave "dots"
along the line. This is because you really is drawing many short connecting
lines and the "dots" appear where these lines overlap.
For Lines, Boxes and Circles transparency is only available in Default mode.
Keyboard shortcuts
1 to 8 - select workspace
Amiga + O - Open animation file
Amiga + A - Create a new animation
Amiga + W - Write to next animiation frame. Will Add a new frame If current
frame is the last frame.
Amiga + U - Write To current animiation frame
Amiga + N - Go To Next frame
Amiga + P - Go To Previous frame
Amiga + G - Write guidelines. Draws thin gray lines To mark the size of the
current animation
