Opacity in PDF Stamp SDK/COM/DLL Library version

Hello,

According to the description of the PDF Stamper, the COM version should support opacity settings.

How can I set the opacity in the veryAddTextEx function?

Regards,
Customer

--------------------------------------------

You can use VeryStampSetFunction() function to set the Opacity option, please refer to following sample code,

//define for VerySetFunction

#define Very_Set_Range                   131

#define Very_Get_PdfPageCount            206

#define Very_Get_PageBoxForStamp         260

#define Very_Set_Text_Leading            134

#define Very_Set_Opacity                 240

#define Very_Set_EmbedFont               241

#define Very_Get_EmbedFont               241

#define Very_Set_TransparentColor        242

 

id=VeryStampOpen(szPDFFile,"_001.pdf");

if(id>0)

{

    int page = 1;

    int pagecount = VeryStampGetFunction(id, Very_Get_PdfPageCount, 0, 0, 0, 0);

    VeryStampSetFunction(id, Very_Set_Opacity, 50, 0, 0, 0);

    for(page = 1; page <= pagecount; page++)

    {

        char szStampBuf[1024];

        int left = VeryStampGetFunction(id, Very_Get_PageBoxForStamp, page, 0, "left", 0);

        int top = VeryStampGetFunction(id, Very_Get_PageBoxForStamp, page, 0, "top", 0);

        int pagewidth = VeryStampGetFunction(id, Very_Get_PageBoxForStamp,

                        page, 0, "width", 0);

        int pageheight = VeryStampGetFunction(id, Very_Get_PageBoxForStamp,

                        page, 0, "height", 0);

        VeryStampSetFunction(id, Very_Set_Range, page, 1, 0, 0);

        sprintf(szStampBuf,"Page:<%d>, Page Box: [%d %d %d %d]",

                        pagecount-page+1,left,top,pagewidth,pageheight);

        VeryStampAddText(id, 2, szStampBuf,255,0,0,0,0,0,0,

                         300,0,10,1,"http://www.verypdf.com",0);

        VeryStampSetFunction(id,Very_Set_Text_Leading,20,0,0,0);

        strcpy(m_szStampBuf,"2200444\n20555\n2200666\n2777");

        VeryStampAddText(id, 1, szStampBuf, 255,18,0,0,0,0,0,200,0,10,1,NULL,0);

    }

    VeryStampClose(id);

}

 

For example,
