Selector de resultados
Descripción
The output selection control is used to create new layers.
In this example the output selection control is shown in the lower right corner of the dialog (1):
Output file selection
The selector consists of two components:
- For the output image, you can choose whether to apply the filters over the image in the current view (only for display) or save the output as a new layer.
- The option "Only on visualization" does not change the original layer, but will apply the list of filters when drawing and re-drawing the view. This option is faster when the image is very large (as the filters are only applied to the current view, not to the whole image), but it slows down the drawing and re-drawing of the view.
- The option "New Layer" will apply all the filters to the image and save the output to a new layer. This is faster when the image size is medium or small and the applied changes are considerable. The generation of the new layer will take some time, but then the displaying is as fast as it would be without the filters.
Both options have advantages and disadvantages, and it is up to the user to decide which option to choose.
- When selecting the option "New Layer", a second option control is enabled in which you can choose whether to save the layer to disk (Create file) with a file name specified in the text box (2), or to create a temporary gvSIG layer (Open in memory).
The new layer will be added to the view, and the TOC will show the layer name as specified in the text box.
** Note: The temporary working space of gvSIG is cleaned automatically, so any temporary layers will be deleted when exiting the application.
