To use the ImageGear PDF Component, you have attach this component to core ImageGear using the function IG_comm_comp_attach:
Copy Code | |
---|---|
IG_comm_comp_attach("PDF")
|
To check if the Component is attached successfully, use the function IG_comm_comp_check:
Copy Code | |
---|---|
IG_comm_comp_check("PDF")
|
This function (method) returns TRUE if the Component is attached.
Initializing the Component
To initialize the ImageGear PDF component, the "PDF" component needs to be attached to the ImageGear component manager.
The following resource content is required by the ImageGear PDF component initialization routine.
Resource\PDF\CIDFont\ | PDF CID fonts directory |
Resource\PDF\CMap\ | PDF font CMaps directory |
Resource\PDF\Font\ | PDF fonts directory |
Resource\PDF\Unicode\ | PDF unicode mappings directory |
Resource\PS\ColorRendering\ | Color rendering PostScript |
Resource\PS\ICCProfiles\ | Directory containing the ICC profiles that allow using the Adobe Color Engine (ACE) |

PDF Global Control Parameters
PDF.ENABLE_POSTSCRIPT
Used to enable/disable PostScript support in PDF component.
By default the ImageGear PDF Component enables PDF and PostScript file format support. But it is possible to disable PostScript file format support in case if it is not required. There is a boolean global parameter named PDF.ENABLE_POSTSCRIPT used to control this.
To disable PostScript use:
Copy Code | |
---|---|
AT_BOOL bEnable = FALSE; IG_gctrl_item_set( "PDF.ENABLE_POSTSCRIPT", AM_TID_AT_BOOL, &bEnable, sizeof(AT_BOOL), NULL ); |
Retrieving Info About the Component
To retrieve information about the attached Component, call the following function:
Copy Code | |
---|---|
IG_comm_comp_list(LPUINT *lpnCount, UINT nIndex, LPCHAR lpComp, DWORD dwCompSize, LPUINT lpnRevMajor, LPUINT lpnRevMinor, LPUINT lpnRevUpdate, LPCHAR lpBuildDate, UINT nBDSize, LPCHAR lpInfoStr, UINT nISSize) |
This function (methods) provides you with the full list of info about the component determined by nIndex index from the list of currently attached components whose number are returned trough lpnCount argument.
