roImagePlayer

This object displays static bitmap images on the video display. The simplest way to use roImagePlayer is to make calls to

DisplayFile() with the filename as a String. Alternatively, you can use PreloadFile() in conjunction with

DisplayPreload() to have more control. For more pleasing aesthetics when generating an image player, use

the roImageWidget object.

Object Creation: The image player is displayed by first creating roRectangle and roImagePlayer instances, then calling

SetRectangle() using the roRectangle instance as the argument.

rectangle = CreateObject("roRectangle", 0, 0, 1024, 768)

i = CreateObject("roImagePlayer")

i.SetRectangle(rectangle)

Interfaces: ifImageControl

The ifImageControl interface provides the following:

• DisplayFile(image_filename As String) As Boolean: Displays the image with the specified filename.

The image_filename string must point to a .png, .jpeg, or 8-bit, 24-bit, or 32-bit .bmp file. Note that .jpeg image

files with CMYK color profiles are not supported.

• DisplayFile(parameters As roAssociativeArray) As Boolean: Displays an image using an

associative array of display parameters:

o Filename

o Mode: See the entry for SetDefaultMode() below for more details.

o Transition: See the entry for SetDefaultTransition() below for more details.
