addAnnotBitmap doesn't work in 2.2.0 9 years 10 months ago #6370

I implemente the method - (BOOL)addAnnotBitmap:(PDF_MATRIX)matrix :(CGImageRef)bitmap :(BOOL)has_alpha :(const PDF_RECT *)rect { return Page_addAnnotBitmap(m_page, matrix, bitmap, has_alpha, rect); } but when i use it although it return true, no image is displayed and the annotation count not increase it value. It is a bug or I did something wrong?

Try using the following:

PDFPos pos = m_view.vGetPos((int)rects[0], (int)rects[1]);//where rect is in screen coordinate.
PDFVPage vpage = m_view.vGetPage(pos.pageno);
Matrix mat = vpage.CreateInvertMatrix(m_view.vGetX(), m_view.vGetY());
mat.TransformRect(rect);
Page page = vpage.GetPage();
page.AddAnnotBitmap(bitmap, has_alpha, rect);
mat.Destroy();

Then you need to rerender the page

Hi,

try to set cache path... something like:

NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
cachesPath = [cachesPath stringByAppendingPathComponent:@"file.dat"];
[m_doc setCache:cachesPath];

it must be set to add an image.

That procedure is already been explained in this old post:
