PNG IMAGE FILES are not opening after IMAGE is CALIBRATED and saved as TIF IMAGE FILE . . .

All --

I have some code which is working with a FOLDER holding multiple PNG IMAGE FILES.

The code can select and open any of the PNG IMAGES files in the FOLDER.

The code relies upon

button_OpenImage_Click

shown below.

The OpenImage Routine works fine until until one of the IMAGES is CALIBRATED and SAVED as a TIF IMAGE FILE.

Then the OpenImage will not work until I use the PREMIER UI to manually open a PNG image in PREMIER.

I hit a glitch related to IMAGE TYPES a while back and was told to use

        'Workaround to save JPG image to TIF file with calibration, switch to TIF writer
        ThisApplication.ActiveImage.File.Format = _
            "tif"

to resolve it.

I have tried inserting

                'Workaround to open PNG image after saving TIF file with calibration
                ThisApplication.ActiveImage.File.Format = _
                    "png"

but the problem persists.

Can someone please suggest a resolution?

Thanks.

Matt,

My guess is that saving this TIFF file might change the current directory from where the PNG files are to somewhere else. Make sure to use the full path when loading the PNG files in your macro.

Thank you for your suggestion.

Something in my PROJECT was changing

 textBox_Folder.Text

and pointing OpenImage to the wrong folder.

Sorry for the false alarm.

Thanks again for your suggestion.
