To make sure that FESTIVAL will be able to run mencoder, type in mencoder at a command prompt (under LInux or Windows). Mencoder must be installed on your computer and the installation directory must be added to your local path. The encoding options can be modified in the text field below.
ACTIVE SKY NEXT USERS GUIDE MOVIE
If the Encode movie box is checked, FESTIVAL will spawn a command to run mencoder to encode the sequence of images into an avi movie. The default is STEREO B on the left, SOHO in the middle and STEREO A on the right. If the Paste box is checked, the images from the different views will be pasted in the order defined in the droplist on the left.
if at least two visualization GUIs are opened. They are available only if your are visalizing data from at least two probes, i.e. These options are used to paste images from different probes side by side. IDL> !TIME_STAMP_BACKGROUND_IS_TRANSPARENT = !TRUE IDL> !TIME_STAMP_POSITION = !TIME_STAMP_BOTTOM_RIGHT Default is 3.0.įor example, to add red time stamps on top of the images in the bottom right corner, use the following IDL commands: The behavior of this option is controlled by the following environment variables: By default, FESTIVAL adds a black background banner on top of the saved images, with the date and time for each image in the view written in white. Starting with version 4.0 of FESTIVAL, the images can be time stamped. The reason is that if you are not in compact mode, the data that form the composite will generally not be synchronized anymore after a few time steps. FESTIVAL warns you if you try to save a sequence while not in compact mode. The current mode (normal, compact, linked) is taken into account as if you were clicking the next image button. The sequence of images saved is equivalent to what you would get by clicking the next button through the list of images. You can change them to save only part of the sequence. By default, the start and end dates of the sequence are the dates of the first and of the last images of the list displayed in the selection GUI. The available image formats are the same as for individual images. mpeg or animated gif) using a video encoding software. These can be turned off by unchecking the corresponding boxes in the system GUI.įESTIVAL is able to save at once a whole sequence of images that can later be put together in a movie (i.e. See the time stamping section of the save sequence GUI for details on the time available options.īy default, a small FESTIVAL logo is added at the bottom left of the images, and a small SECCHI logo is added at the bottom right if SECCHI data are being visualized. Starting with version 4.0 of FESTIVAL, time stamps can be added to the saved images. The maximum resolution is 10000x10000 pixels. If you set the width, the height is computed to preserve the aspect ratio, and vice versa. But you can change the width and height in pixels of the output to produce an image of larger or smaller resolution. By default, the scene is rasterized to produce an output of size equal to that of the visualization area of the GUI. In the bitmap formats (JPEG, BMP, TIFF, PNG), the content of visualization GUI (including the coordinate grid if present) is rasterized before it is saved. As of today, the grid is rasterized also, even though it is a vectorial object within FESTIVAL.
In postscript format, each image forming the composite is stored at its native resolution. You can save the content of a visualization GUI in the following image formats: The autozoom button will put you back on track.įrom this dialog you can print out the content of the visualization GUI. If your data are not visible in the visualization area, one possibility is that you are not looking at the right region of the sky.
The autozoom button adjusts the zoom factor so that the whole composite image of the sky is visible. If your mouse does not have a wheel, you can zoom in and out with these two tools. If your mouse has a wheel, you can also zoom in and out. Click and drag to pan across the composite image. In the visualization GUI, you manipulate the selected data.
