MBOX® USER MANUAL
When pixel mapping sources change size, they typically to change size because they have been intentionally
recongured. e.g. the global surface is resized to accommodate an additional output or a different layout. For the most
part, the resizing of the global surface, outputs, and mixes are user-initiated. However, if the global surface auto-resize
option is checked, it will change size automatically if outputs or mixes are moved/added. In addition, if a layer is used
as the source for pixel mapping, the source size will always change when the size of the content on the layer changes.
Layers have no preset size!
This means that attention should be given to what the pixel mapping sources are and whether they might need to
change size during setup and programming, or whether (in the case of layers) they might even change size at different
moments during the show. If the sources are the global surface and/or outputs and mixes, then once setup is complete
these will likely never change size again, and for the most part these sources won’t need the auto-resizing enabled. But
if the source is a layer and content sizes change during the show, it’s a very good idea to enable the auto-resizing. Of
course, if a particular layer only ever plays a single size of content, then that size could be set and the auto-resizing not
enabled.
When a new source (i.e. a source that isn’t already being used by another context) is selected for a context, a tab will
appear for that source. The source tabs are labeled with the name of the source. Clicking on the tab shows the currently
set size of the source, and if this size does not match what the Mbox application is using for that source, the button
below will have the current source size shown in red. Pressing the button will change the source’s size to whatever size
Mbox is using. There is a new checkbox to the right of the size elds that when checked causes the source size in the
pixel mapping editor to automatically update when the actual source changes size. This setting can be used together
with the auto-resize option for the contexts to ensure that the correct/current sizes for sources and contexts are shown
in the editor.
If Mbox Remote is in a live editing session when a pixel mapping source changes size and both of the resizing
preferences are enabled then the only indication will be that content may no longer ll, or may overll the current layout
of xtures. With the source size automatic updating disabled, the tab for that source will be colored red if the source
changes size.
CAUTION! If the pixel mapping is set up to for pixel-for-pixel sampling between content and xtures, then enabling the
auto-resizing can affect that relationship severely. Care should be taken if the source size changes, and changes on the
y (i.e. using a layer as a source and playing content of a different size) should be avoided.
