JPEGExporterMBS.data as string
Function:
The destination string.
Notes:
If file is nil, the compressed data is saved in this property.
The returned string has the encoding set to MacRoman. If you want to concat the string with another you should change the encoding, so both strings have the same encoding. If you don't handle that RB may convert the JPEG data to UTF8 (Unicode) which will destroy it.

JPEGExporterMBS.YieldTicks as Integer
Function:
How much time is given back to Xojo for other ticks.
Example:
Notes:
If value is greater than zero, the application will yield to another RB thread after the given number of ticks have passed. 60 ticks are one second. Using a small value can slow down processing a lot while a big value keeps your application not responding to mouse clicks.
If you use this property with e.g. 6 as the value, you may also want to use this method in a thread so you can handle mouse events or let Xojo redraw a progressbar.

| Type | Topic | Plugin | Version | macOS | Windows | Linux | Console & Web | iOS |
| property | JPEG | MBS Images Plugin | 7.3 | Yes | Yes | Yes | Yes | No |
Example:
dim j as JPEGExporterMBS // your exporter
j.YieldTicks=6 // only use 1/10th of a second
If value is greater than zero, the application will yield to another RB thread after the given number of ticks have passed. 60 ticks are one second. Using a small value can slow down processing a lot while a big value keeps your application not responding to mouse clicks.
If you use this property with e.g. 6 as the value, you may also want to use this method in a thread so you can handle mouse events or let Xojo redraw a progressbar.
