I've been looking for a simple way to determine the size in bytes of the loaded image. I don't want to have to write the image to disk and see the image size in bytes. I have the image loaded I should be able to tell the size.

Thank you

Hi

24bit color images have 3 RGB values per pixel so you can work out the size in bytes as:

W X H x 3

Following up on this, why don't you have a property that does this for us? Meaning, instead of me determining the bit of the image, just have you test that and publish a read-only property that has the actual size.

A more generic way:
size := ImageEnView1.IEBitmap.Height * ImageEnView1.IEBitmap.RowLen;

It measures size in bytes, counting also padding bytes, for all pixel formats.
