WORK WITH A SMALL CANVAS
FRAME AN IMAGE
Bear in mind that the process to calculate an image implies a great number of mathematical operations in order to determine the colour of each pixel. If the canvas is smaller it will have less number of pixels to calculate, therefore the image will be calculated faster.
It is due this reason that it is recommended to use a small canvas when exploring a fractal and, once we get the wished aspect, resize it to generate the final image.
STOP UNNECESSARY CALCULATIONS
Following the previous advice about small canvases, it may happen that the final image (already resized with the wished dimensions) shows a different framing than before. This can be easily avoided by keeping in mind from the beginning the aspect ratio wanted for the final image.
For example, if we want to generate an 800 x 600 px image it is recommended to work with a smaller canvas with proportional dimensions. The aspect ratio we want is 800/600 = 1.33, thus any canvas with that aspect ratio will allow to avoid the problem, i.e. 200 x 150 px.
USING AN APPROPIATE NUMBER OF ITERATIONS
When using the option "Activate image refreshing" the fractal shows up as it is calculated, and sometimes we will be able to see that the process does not offer the expected results. In this situation it is useful to stop the calculation by pressing the key "Escape" (to do this the canvas must be in the forefront).
HOW NOT TO LOSE AN INTERESTING AREA
The number of iterations in a fractal is a similar feature to the resolution in a photo: the more we have, the more we could enlarge the image without losing its quality.
Calculating a fractal with a high number of iterations slows the process, what would be vain if we do not intend to apply a zoom +. It is for this reason that it is recommendable to increase gradually the number of iterations at the same time that we zoom in. It is equally recommendable to decrease the number of iterations as we zoom out.
USING RANDOMIZED PALETTES
When exploring a fractal, it may happen that there is more than one interesting area in a same image. In order to explore them all individually with no risks of losing their locations, some copies of the canvas can be done. If so, copy the canvas from the "Edit" menu or press "Control + C" (to do this the canvas must be in the forefront).
CHOOSING A FORMAT TO SAVE IMAGES
When we use a randomized palette to draw a fractal, the colours chosen randomly will be the same during its exploration, but note that when saving its parameters (by registering a point or exporting them) the colours will not be included. It is for this reason that when reloading this point in the fractal, the image will show other colours. If you want to save a final image file it is recommendable to do several copies of the canvas till you find the desired colours. To do this, copy the canvas from the "Edit" menu or press "Control + C" (to do this the canvas must be in the forefront).
A personal advice concerning visual results is using a randomized palette as a base and an orbit trap with a fixed colours palette.
In EFF the default format for an image is PNG. It is highly recommendable to save images in this format because it offers the maximum quality with the advantage of compression without losing information.
Although JPG format generates smaller files, it is not recommended its use with the exception of insufficient device space. This is because a JPG compress the image and produces losses of information that, in order to obtain the image, took thousands of calculations.
SHARE PARAMETERS WITH OTHER USERS
To create a wallpaper, adjust the canvas' aspect-ratio to the "Screen aspect-ratio" with the function "Set aspect-ratio" from the menu "Window". Once the image is ready, change the size of the canvas to "Full screen" with the function "Set size (px)" in the menu "Window". The final image will have the wished framing and dimensions.
MODIFY PARAMETERS ACCURATELY
It is very recommendable to share parameters with other EFF users because it increases the possibilities of working and discover areas of interest that otherwise would be impossible to find by oneself among the fractal complexity. It is for this that EFF offers the following options:
The best suggestion is to check the box "Publish" when you are registering a point of the fractal. If you choose so you would be collaborating in the creation of an online library in an anonymous way. This collection also acts as a backup.
Another option is exporting the parameters to a file or a line of text and send them via email or transfer them using an other way.
APPLY FEATURES FROM ONE CANVAS TO ANOTHER ONE
When working with a zoom in on the fractal it may happen that as you change one of the parameters the image changes abruptly, disappearing even. In order to control this situation the parameters enclose a big number of decimals, what allows to modify them accurately concerning the level of zoom in of the image.
TO CREATE BETTER ORBIT TRAP PATTERNS
In order to apply the palette of a canvas in another one select the original canvas and open the formulary "Edit" from the menu "View". In the flap "Palette", check the box "Current palette", so the formulary obtains the data and uncheck so it does not alter when selecting other canvases. Then, select the destination canvas and, in the formulary "Edit", press the button "Apply".
Other formulary features can be also copied using this method in the application.
GET ADDITIONAL INFORMATION
In order to create a customized orbit trap you can draw a PNG image with transparent areas and import it as a pattern. When using this pattern as an orbit trap, the fractal will be drawn with its image, and the transparent areas will let see what is underneath.
In order to avoid a pixelated result the image must have large dimensions, due to the drawing process will adapt it to the fractal folding and stretching it.
A bigger image also allows zooming in deeper into the fractal and makes it harder to lose quality all too soon.
EFF disposes of a web desktop with direct access to www.fractfinder.es, where you can find updated information in order to make the most of this application. This web desktop is set within the EFF main frame to improve the experience, allowing the user to interact with the information and the application at once. The web desktop can be opened from the menu "View" or pressing "Control + Alt + W".
Note that when the browser is selected it is not possible to use the keyboard shortcuts to access the functions neither in the menu "File" nor "Edit". To do so, keeping the browser open, activate any other formulary of the application.
