Re: What is the PictureBox downsampling for its bitmap?

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Thanks a lot Herfried,

The image I'm drawing is the ultrasonic result of some scan.
The values of the image pixels are in the range of 0 to 255 and the image is
PixelFormat.Format8bppIndexed with color palette.
The important thing for me is that when the image is shrunken, the defects
that are drawn in the image will be visible at all time by taking the maximum
value from the shrunken grid. For example; if a 4 square pixels is shrink to
a single pixel, the the single pixel will have the maximum value of the four.
I don't see in which InterpolationMode I can use for this.

Is it possible? How?

Thanks
Sharon

Am I right?

Yes, you are right in the case of the picturebox.

Can you forward me dor more detailed specification about the
InterpolationMode options, so I'll be able to see if I can use one of
them,
specially for the max method.
