Help
File
File|New
Initialisizes the current fractal-type with the program-internal default-values
and recalculates the image.
File|Open
Loads an previusly saved parameter-file and recalculates the image. The behaviour may
change in further versions.
File|Save
Saves the current picture as a wind**f-bmp- file. The parameters must be saved
with save params.
File|Save Params
The current settings are saved to a file. This file can be loaded to recalculate
the image. See Open. During the development-phase the
format of the parameter-files may change.
File|Settings
Opens a dialog, with file-related settings.
Save Colormap
Enables or disables the saving of the colormap into the parameterfile.
If the colormap is saved in the parameterfile, this map is automatically
assigned to the image. No extra colormap-file is needed. The size of the
parameterfile increases by approx. 800 bytes.
Startupfile
Defines a parameterfile, which is automatically loaded at the programmstart.
Click on the search-button to select a file or enter it directly. Leave the
field blank, if no file schould be loaded.
File|Exit
Exits the program (without any confirmations).
Fractal
Fractal|Type
Select a fractal-type. The listbox displays all implemeted fractal-types.
Double-click to the desired type to select it. The image is calculated with
the default-values.
Fractal|Parameter
This tabbed dialog is used to set up the fractal-indepent parameters.
Page General
Page General: Maximun iterations deep. If the iterations-count reaches
this value, the iteration ends and the point is "inside".
Page Corners
The corner values of the fractal can be modified here. The default-button resets the
values to the initial-values.
Page Convergency
This page presents all convergecy-depend values.
- Bailout-value: If the absolute value of the result of the fractal-function
if greater than the bailout-value, the iteration bails out and the poit is
"outside"
- Convfunc: This is a special method for the bailout-test. The following
settings are possible:
- default: The radius around the orgin. Is the point outside this radius,
the function exits.
- Real: Only the real-part of the function result is used for the bailout-tests.
- Imag: The imaginary part is used.
- And: The real AND the imaginary part must be outside the radius.
- Or: The real OR the imaginary part must be outside.
Postcompute
This page shows options for the post-computing of each pixel. The postcomputing
is called ater the point is calculated by the fractal-function. The
postcomputing is only avaible for field types.
Inside
The inside postcompute is uses for points inside the fractal
(maximun iterations reached).
- Color X: The point becomes this color.
- Maxiter : Color defined by the maximun iterations (evtl truncated).
- Multiply : Real and imaginary part are multiplied and scaled.
- Altitude : The (real) value |Z| colors the point.
- Addition : Real and imaginary part are added and scaled.
- atan: the arcustangens(Real/imag) is computed.
Outside
The outside postcompute is used for outside points (aborted
by the convergency function).
- Iter : Iterations reached for this point.
- Potential : Make a floating color image.
- others : see inside postcompute
Color Mapping
Changes between normal and logarithmic color mapping.
- Colormode : selects the coloring mode. All other settigs in this group are
only valid, when logarithmic mapping is selected.
- First Color : Sets the first iteration, where the log-map begins. All
iters below this value becomes color 0.
- Shift : Shifts the logarithmic function. A low value makes a "sharper" log,
a higher value makes a more linear function. The value must greater then zero.
- compute first color: if checked, the first color is automatically computed.
Page Parameters
Here are the sixteen internal parameter-values shown. This is a general page.
If there is a type-specific setup, it schoud be
used first. Not all values may be used, depends on the current fractal-type.
Page Information
This page shows some information about the current fractal.
The values are read-only, no settings can be done.
Fractal|Type-specific
Setup of all type-depend values. The apperance of this dialog changes with the
current fractal-type.
Parameteranimation
Shows a dialog for creating parameter animations. The program creates a series
of single images, for the final animation is an external program requiered,
which converts the images to the animation.
- Load reads a saved animations definition file.
- Save saves the current animation settings to disk.
- Start/Abort starts the calculation of the animation or aborts a running
calculation.
- Close ends the parameter animation dialog.
The settings must be saved before closing the dialog.
Page Parameters
The parameter page shows the float parameters curve. All sixteen parameters are
avaible here. Each parameter is displayed in a different color. The color and
the number of the current parameter is visible at the button.
- To mofify the current parameter, click on the edit button
- To toggle the visible status, ckick the Display checkbox. By default,
the first two parameters (p0, p1) are visible.
- To change the current parameter, click on the "<--" and "-->" buttons.
- The Testcalc button calculates an image with the current values.
First select the position of the image parameter graph by clicking inside with
the left mousebutton. The position is marked by a dashed line.
- The posneg check toggles between positive and positive/negative
display of the parameters.
- The Zoombuttons zooms in or out to display big or small values.
Page Pictures
Setup for the animation length, framecount etc...
- #Pictures : Total framecount of the animation
- Start Image : First image to be computed.
- Last Image : Last image to be computed (for range calculation)
- Increment : Sets the increment between two calculated images.
- FileMask : The format string for the filename of the saved images.
The format string must be conform to the C printf format string.
Page Status
The status page shows the status of a running animation calculation.
Picture
Picture- and colormap settings
Picture|General Settings
This dialog shows all picture-relevant settings.
- Color deeps: setup of the color-deep for the image.
- 1 bit: Two color image
- 8 bit: 256 colors with a palette
- 32 bit: Truecolor without palette
- Image Size: Sets the image-size exactly. The most relevant sizes can be
adjusted by pressing one of the four buttons.
- Displaying: Sets the displaying properties during image calculation.
Display during calc enables or disables the displaying of the image during
the calculation. Disabling displaying make the rendering faster. If the
image displaying is enabled, the lines per update sets the update frequency.
Lower values - shorter updates - slower calculation!
Picture|Edit Palette
Editor for the colormap. This make only sense, when the 8-bit display-mode is
activated.
- Modifying a single color: Double-click on the desired colorcell. A color-selection-dialog
apperas. Click ok to accept the color.
- Color-Crossing (Farbverlauf): Click in the colorgrid to select the starting
point. Click on the button named 'verlauf', now the crossing-mode is active.
Click on the second point. The colors between the start- and the endpoint are
interpolated. To abort an activated crossing-mode click on the verlauf-button
again. After creating the color-crossing, the crossing-mode is automatically
deactivated.
- The colormap can be rotated with the '+' and the '-' buttons. the '+' button
rotates right, the '-' button rotates left.
- The 'default' button restores the startup-colormap.
- To accept the changes, press 'ok'
- To forget the changes, press 'cancel'
Picture|Load Palette
Loads a saved colormap.
Picture|Save Palette
Saves the current colormap
The colormaps are saved as textfiles. Each line contains thee decimal values
for the red,green and blue part of the color. Each file has 256 lines.
The map-files are compatible with Mandel Ultimativ for OS/2 and Fractint.
Zoom
Zoom|Zoom in
Zooms into the fractal with a fixed factor.
Zoom|Zoom out
Zooms out with a fixed factor.
The factor can be set in the Settings-dialog.
Zoom|Zoom Setup
This page presents all zoom-relevant settings.
Zoomfactor-setting
This zoom-factor is used for the point & click - zooming. With the slider, the
zoom-factor can be adjusted quickly in the range 1 to 30. In the entry-field the
factor can be edited without any limitiations. An useful range for the
zoom-factor is 1 to 30.
Zoom Factor Animation
These settings are used for the antimatin-zoom. Mandel Ultimativ renders
automatically numpic images, each zoomed by the animationszoomfactor.
