I have a question about the performance of the cornerSubPix() function and would like to upload a reference image and the code I am using to find the subpixel resolution of the corners.

What is the best way to upload a .pgm image for reference by readers of this forum?

hi wpd, it's not difficult at all,

when writing or editing your question, just look for the image-button shown here (in the middle):

image description

you just can't post ppm images, only gif,png,jpeg formats can be properly stored, so try to convert your image before

Uploading images towards the forum itself results in low resolution and crappy images. I always suggest people to upload their picture on online services like tinypic and then link the image here. That works way better and you get a full resolution image.

But these hosters tend to delete images after some time. And then the question is useless for someone with a similar problem.

Thanks for the tips... I have a specific question about a specific image, so I don't want my image to be corrupted by the compression process. I was hoping somebody could tell me, "The way we usually do this on the OpenCV forum is to upload the image to Google Photo Archive(tm), where it will be be archived, uncompressed, for all eternity." I feel like this should be a solved problem for the OpenCV forum, and that I'm missing something fundamental by not being able to find the solution easily.

wpd, choose png then (lossless compression)
