how to get coordinates was created by Shades

Hello,

I am trying to get the coordinates of an image that I merged with a pdf,but I think there is something wrong :

Code:

struct PDFV_POS pos1;
    struct PDFV_POS pos2;
       [m_view vGetPos:&pos1 :imageViewFrame.origin.x /m_scale :imageViewFrame.origin.y /m_scale];
    [m_view vGetPos:&pos2 :(imageViewFrame.origin.x + imageViewFrame.size.width) / m_scale :(imageViewFrame.origin.y + imageViewFrame.size.height) / m_scale];
     PDF_RECT rect;
     rect.left = pos1.x;
    rect.right = pos2.x;
    rect.top = pos2.y;
    rect.bottom = pos1.y;
   
 newFrame = CGRectMake(rect.left , rect.top, rect.right,  rect.bottom);

Can you please help me ?

Thank you

Hi,

you could try something like;

Code:

[m_view vGetPos:&pos1 :imageViewFrame.origin.x :imageViewFrame.origin.y + imageViewFrame.size.height];
[m_view vGetPos:&pos2 :imageViewFrame.origin.x + imageViewFrame.size.width :imageViewFrame.origin.y];

Thank you
But actually I get wrong values after doing this :

Code:

    [m_view vGetPos:&pos1 :frame.origin.x/m_scale :(frame.origin.y + frame.size.height)/m_scale];
    [m_view vGetPos:&pos2 :(frame.origin.x + frame.size.width)/m_scale :frame.origin.y/m_scale];
    PDF_RECT rect;
    rect.left = pos1.x;
    rect.right = pos2.x;
    rect.top = pos2.y;
    rect.bottom = pos1.y;

Hi,

the following code uses also the m_scale to get the correct rect:

Code:

    [m_view vGetPos:&pos1 :imageViewFrame.origin.x * m_scale :(imageViewFrame.origin.y + imageViewFrame.size.height) * m_scale];
    [m_view vGetPos:&pos2 :(imageViewFrame.origin.x + imageViewFrame.size.width) * m_scale :imageViewFrame.origin.y * m_scale];
    
    PDF_RECT rect;
    rect.left = pos1.x;
    rect.top = pos1.y;
    rect.right = pos2.x;
    rect.bottom = pos2.y;

Pay attention to use correct coordinates to create your PDF_RECT

Hi
While following the code you had transmitted to me, I have always faced wrong positions:
When I do :

Code:

CGRect newFrame = CGRectMake(rect.left , rect.top, rect.right, rect.bottom);

This gives back a “y” at the top of the page while it should be at the bottom of the page..
can you please clarify it to me further ?

Thank you
