i'm trying to run the OMR-Anchor sample without being able to make it work.
The problem i think is because calling:
m_GdPictureImaging.CreateAnchorTemplate( m_TemplateImg, m_AnchorLeft, m_AnchorTop, m_AnchorWidth, m_AnchorHeight );
always returns 0, while m_GdPictureImaging.GetStat( )returns OK.
I tried with JPGs and PNGs, even with the one found at this URL http://www.gdpicture.com/products/plugi ... essing.php. The result is always the same.
Trying to proceed width the method FindAnchor will result on a "Error: 2" message box (invalid parameter).
Could you please let me know what i'm missing? Is there any requirement on the file type (resolution, file size, file type) ?
I tried with different files, but i got the same behaviour even with this image: http://www.gdpicture.com/images/gdpicture-omr.png , which you suggested in another post.
In this image, the area i try to select is the one marked in blue. I checked the coordinate returned by the viewer and seem ok, but CreateAnchorTemplate still return 0.
You are right. We have a problem with color image that we just fixed for the next minor release.
We are currently able to handle 1bpp image only, but we will support any kind of bitmap in a couple of days max...
I have a problem when use findAnchor, always return invalid parameter
I create a template with L=74, T=39, W=73, H=107
TemplateId = m_objImaging.CreateAnchorTemplate(iImgRefClone, L, T, W, H)
I Try to findanchor with the same values and return values at zero
status = m_objImaging.FindAnchor(iImgDocClone, TemplateId, ModoOMR, L, T, W, H, _xr, _yr, _wr, _hr, Coincide)
THIS ALWAYS RETURN INVALID PARAMETER
But if i use -> status = m_objImaging.FindAnchor(iImgDocClone, TemplateId, ModoOMR, 0, 0, WIDTH of IiMageDocClone, Height of iImgDocClone , ....) returns OK
Thank you very much for you fastest response and solution
One more question....
When i uses findanchortemplate over two totaly diferent images i got a very hight accuracy return values.(like 97%)
What is the accuracy level that i can say "the image is not located"?
You can consider good matching an accuracy between 90% & 100% if the template is correctly defined. From the reference guide:
Let me know if you need further information.To maximize detection speed and accuracy, the Anchor region must contain less than 50% of white pixels and must have as less white margins as possible.
