Function Reference

Page 363 of 839

GetActiveFont

Syntax:

SI32 pdfGetActiveFont(

const PPDF* IPDF) // Instance pointer

The function returns the handle of the active font or -1 if no font is set.

GetAllocBy

Syntax:

SI32 pdfGetAllocBy(

const PPDF* IPDF) // Instance pointer

The function returns the pre-allocated buffer size of page content streams in bytes. Memory

allocation is slow, especially re-allocation of memory by using realloc(). Because of this all content

streams are buffered by DynaPDF to avoid too much memory allocation calls. The property AllocBy

defines the size of memory that is allocated each time when more memory must be allocated.

The processing speed depends heavily on memory allocation. The default size of pre-allocated

memory for content streams is 16 KB. It can be set to a larger or smaller value if necessary to

improve processing speed.

However, if too much memory is allocated at runtime, processing speed will be slower and an out of

memory exception can occur. If the size is too small, processing speed is slower too because of the

many memory allocation calls. In most cases, it is not required to change the property AllocBy.
