you can get stroke color and set back to annotation with different alpha.
and then set fill color.

it can't change alpha value if set fill color only,

for add rect annotation with fill color:

Code:

Page_AddAnnotRect( page, mat, rect, strokecolor_and_alpha, fill_color_with_255_alpha );

for add rect annotation without fill color:

Code:

Page_AddAnnotRect( page, mat, rect, strokecolor_and_alpha, fill_color_with_0_alpha );

set alpha for rect annotation:

Code:

int clr = Page_GetAnnotStrokeColor(page, annot);
clr &= 0xFFFFFF;//clear alpha value;
clr |= (alpha<<24);//set alpha value, alpha value is in range [0,255];
Page_SetAnnotStrokeColor( page, annot, clr );

set all values:

Code:

int stroke_clr = Page_GetAnnotStrokeColor(page, annot);
stroke_clr &= 0xFFFFFF;//clear alpha value;
stroke_clr |= (alpha<<24);//set alpha value, alpha value is in range [0,255];
int fill_clr = 0xFF000000 | your_fill_color;
Page_SetAnnotFillColor( page, annot, fill_clr );
Page_SetAnnotStrokeColor( page, annot, stroke_clr );
Page_SetAnnotStrokeWidth( page, annot, stroke_width );
