Help with resizing please


Recommended Posts

When using signatures in most forums, the size is restricted.

I'm restricted to 15k in one such forum.

Of course I know how to set the dimensions of a picture, but I need to know more about restricting the file size.

I've recently noticed that in the top left corner of the image resize dialog, the predicted dimensions of the new size are given before you complete a resizing.

The problem is, that number never matches what the actual size turns out to be when I check it later.

For instance, a sig I made tonight showed that it would be 15k in the dialog box, but the finished picture was just over 10k after it was saved.

Does anyone know what I'm doing wrong?

P.S. May I ask a stupid windows question. When checking the size under properties, what's the difference between the "size" and the "size on disk"? They're always two different numbers. (neither of which match the dialog size in PDN)

I will appreciate your help. Thanks

1. Predicted size in the resize dialog might be the size of BMP or PDN file type with the current dimensions. Saving to a JPEG file could reduce size - i think you can adjust this with a Save - config dialog

2. Any hard disk is cut into small pieces so that it can be addressed by the disk controller and the operating system. So every file saved onto the disk is cut in such pieces to fit on the disk. For example many windows systems cut the disk into pieces of 4 Kb. If you have a file of size 19Kb then you will fill 4 full pieces of the disk and a fifth which will have 1 of 4 Kb filled that makes 5 pieces filled. So real size is 19 Kb but 20 Kb size on disk.

Thank you. It was indeed saved as a jpeg.

Of course the predicted size would be different for different file types.

I'm embarrassed this didn't occur to me. I'll look for the save configuration dialog you mentioned.

I see. Then ultimately the save size is the true size and the only one I need to be concerned with.

This was very helpful. Thank you again.
