PA_GetBlobHandleParameter (params; index) → PA_Handle
| Parameter | Type | Description | |
| params | PA_PluginParameters | → | Parameters received in PluginMain |
| index | short | → | Index of the parameter in params |
| Function result | PA_Handle | ← | A handle to the BLOB parameter |
Description
The command
PA_GetBlobHandleParameter
returns a handle to the BLOB that is in the
index
parameter of
params
.
This may be very useful, especially when the plug-in wants to read the BLOB without modifying it. On the other hand,
PA_GetBlobParameter
gets a copy of the BLOB and can manipulate it, but this may lead to memory problems for "large" BLOBs.
WARNING
The handle belongs to 4D; never dispose of it.
