Pattern Matching and Vision Builder 6.0

[Miguel]

Hi,

When I select a ROI from an image to generate a pattern matching, Builder
saves it as a PNG file.

If I open this pattern in other application (Paint Shop Pro 7) to modified
it and save as a PNG file, after I can't open this file as a pattern into
Builder, because it is considered as a not valid PNG file.

I have tested this case in LabView 6.i and this problem doesn't appear.

Any solution? Thanks.

When the template is first saved in Vision Builder, pattern matching information is stored in the header of the PNG file. This information lets LabVIEW and Vision Builder know how the template was learned. Paint Shop Pro does not keep this information in the file whenever it is saved so Vision Builder will not recognize it as a valid pattern matching template.
