Skip non-image files when adding images to array from file

[tyrrellvw]

Hi,

I am reading images that are stored in a folder into an image array. I have a slight problem when a non image file (using .png) is present.

What I have tried is to use a case structure to check if the file extension is a png (if it is a png then add to the array), if it is not a png file, then the false case is executed and a blank is inserted into the image array, since I have selected to "Use default if unwired". What I ultimately would like is for it to skip all non image files and have a image array with no blanks.

I honestly do not know what to do.

Could anyone please offer advice? Let me know if you would like any other information.

Regards,

Richard

 Use a Pattern filer when you get your files from the folder, then you don't need to sort the files out after - Simple

Hi Richard,

while James noted the correct approach to only list PNG files in the first place you should consider for the next time:

Only do your "add to array" operation in the TRUE case. Then you don't need to output some default values from your case structure!

Thank you James! 

I will be honest, I saw that VI but I was unsure about what it did. I was using the List Folder VI and then comparing each file in the folder.

Still a rookie and had to self teach myself LabVIEW, there are a few things that I overlook.
