method | Compression | MBS Compression Plugin | 9.4 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
The buffer size you specify is the output buffer size.
If this size is small, you need to flush with ProcessZip.

Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
method | Compression | MBS Compression Plugin | 3.3 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
The buffer is cleared after this function returns.
ZLibCompressMBS.InitZip(level as Integer)
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
method | Compression | MBS Compression Plugin | 3.3 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
Level is from 0 to 9.

ZLibCompressMBS.InputAvail as Integer
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
method | Compression | MBS Compression Plugin | 3.3 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
ZLibCompressMBS.OutputSize as Integer

method | Compression | MBS Compression Plugin | 3.3 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
method | Compression | MBS Compression Plugin | 14.4 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
If error is zero after this function, please call it again.
Error is 1 if stream is at end, so you can call EndZip to finish.
ZLibCompressMBS.ProcessZip(Flush as boolean=false)
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
method | Compression | MBS Compression Plugin | 3.3 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
Reduces the size of the input buffer and writes new data to the output buffer.
If the input buffer is not empty after this call, you need to call it again, but empty the output buffer before.
Error is set.
If flush is true, the data is flushed to output. Using flush=true all the the time will slow down compression, so use it only on the end to clear the output buffers.
ZLibCompressMBS.SetInput(data as MemoryBlock) as boolean
Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
method | Compression | MBS Compression Plugin | 13.0 | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes | All |
Returns true if successfull.
The current input buffer size is 128 K, so you may use something smaller.
