addAnnotBitmap doesn't work in 2.2.0 was created by Rossi

I tied to add an image to pdfview. I implemente the method

Code:

- (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:

Code:

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

Sorry, i don't understand how to use your code.
- PDFPos return unknown type (i generally use PDFV_POS)
- how i should create rects
- Matrix is also unknown type and the method CreateInvertMatrix does not exist

Please can you explain me your code?

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:
