This structure contains the description of a buffer used for hatching purposes or the point-in-area test.

Element Description

Buffer

[void*] Address of the buffer data area. This pointer will be initialized when calling MKI_BUFFER::Alloc and freed when calling MKI_BUFFER::Free. Do not modify!

ElemRect

[MKI_RECT] The smallest rectangle surrounding all objects stored in this buffer. Do not modify!

ElemMax

[__int32] Maximum number of objects to be stored in this buffer. Do not modify!

ElemCount

[__int32] Current number of objects stored in this buffer. Do not modify!

PolygonCount

[__int32] Current number of independent paths stored in this buffer. You may modify this value during buffer filling.

ClosedOnly

[bool] If true, the buffer will only accept "closed" objects, i.e. objects that have a closed outline like circles, ellipses, surfaces, etc.

Interruptible New in Version 2023.2

[bool] If true, the progress of operations using this buffer is displayed in the status line and they can be interrupted by pressing the ESC key. Do not use for background operations!
