The text inside a PDF file is usually split into multiple parts, a single sentence or paragraph can consist of multiple pieces of text positioned independently inside the PDF document. The Optimize or DocOptimize methods attempt to regroup lines or paragraphs prior to exporting the PDF file into another format, or to make the file easier to edit.
void Optimize(System.Int16 Level)
int DocOptimize(EXTDOCHANDLE edhDocument, int iLevel)
Level, iLevel
Optimization level to apply to PDF document.
Optimization Level |
Value |
|---|---|
No optimization |
0 |
Line optimization |
1 |
Paragraph optimization |
2 |
edhDocument
Handle Returned by DocOpen.
The return value is zero if the DocOptimize method succeed. If the DocOptimize method fails, a negative value will returned.
There is not value for the Optimize method, though.
Optimizing the document is not recommended when exporting to image formats, it slows down the export and the output might be less accurate.
