when you add a bitmap, you have to set "has_alpha" parameter to true, in Page_addAnnotBitmap method.
I also tried to add a png with transparent background with success

It crashes when you add a bitmap? or in another case?

There is a specific sequence to get this crash?

i think you shall add bitmap first, then, invoke vRenderSync to re-render the page.

I not find vRenderSync function.
This is my code:

Code:

CGImageRef ref = [[UIImage imageNamed:@"emoticon"] CGImage];
PDFMatrix *mat = [vpage CreateMatrix];
BOOL result = [page addAnnotBitmap:mat.handle :ref :YES :&rect];
Matrix_destroy(mat.handle);
[m_view vRenderPage:pos.pageno];
[self refresh];
