 +====== VI10GetDimension ======
 +
 +**V = **//Vector//
 +
 +**I = **//Image//
 +
 +Function that is used to manage the Vector Image feature (object that resides on some Qpaint versions).
 +
 +The VI10GetDimension function adds the GetDimension command queue up the instructions to be processed into the Buffer to perform the drawing.
 +The GetDimension command allows you to read the width and height size in pixels of the VectorImage object.\\
 +This command generates a run-time error then it must be always added as the last execution buffer.
 +
 +===== IMPLEMENTATION =====
 +
 +**VI10GetDimension (awBuffer)**
 +
 +Parameters:
 +
 +^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
 +|  IN  |  ARRSYS /\\ ARRGBL  |  awBuffer  |  W  |Array that serves as a buffer for instructions/data|
 +
 +=== Example ===
 +
 +//TASK_00//
 +<code QCl>
 +MAIN:
 +      VI10InitBuffer(awBuffer)
 +      VI10GetDimension(awBuffer)
 +      VI10DrawBuffer(awBuffer)
 +      VI11WaitBufferReadyUsingWAIT(awBuffer)
 +      VI10ExtractDimension(awBuffer, awWidth, awHeight)
 +      VI10InitBuffer(awBuffer)
 +END
 +</code>
 +
 +=== Note ===
 +  * To extract the data read from GetDimension command you need to use immediately after the [[.:VI10ExtractDimension]] command
 +  * The **GetDimension** command will always generate a run-time error then it must be added as the last execution buffer. Also, after you finish reading the data, you must reinitialize the buffer with the [[.:VI10InitBuffer]] command
