Hi, I'm trying to find out the size of png format image file in pixel after opening one by [openpanel].

Is there anyway to get x,y pixel values of an image file right after opening one?

And one more question, is it possible to know x,y position(pixel) of an image in GEM window? (position of bottom left point of an image)

Also, I figured out moving 1 point in translateXYZ was about 96pixel. Is this true?

I think 1 point in Gem window seems to be changed with the size of Gem window.

So, anyway to find out the x,y pixel values of .png image file?

C'mon guys I need help...!

Try to be patient. This isn't the most active forum in the world, and people who visit come from different time zones.

I haven't used it in a while, but I think there's some thing in Gridflow that can do this. It's a more matrix-based system than Gem.

you can easily do that by using a [pix_info] object. second and third outlet will output the pix dimension in pixels.

the coordinates of a gem window (default window size, view-point and ratio) go from -4 to 4 for both axis with a 500 x 500 pixel size. this means that one "unit" corresponds to ~62 pixels (500 / . if you increase the window size to, say, 800 x 800 pixel, the coordinates will stay the same and one "unit" will be 100 pixel (800 / .

Thank you so much Guido!!

I didn't know [pix_info] object has the function.
Also, coordinates of gem window really helped my understanding.
I'm almost new to GEM, and I'm having so much fun as much as I had in pd.

Thank you.
