Hi
Controls have no "Before Sizing" event, so you will need to maintain a private variable to store it (e.g. setting it at the end of the ImageEnView ViewChange event.

The VisibleBitmapRec does not vibe me what i want so i need to use the math. the only thing is on how would i know the current zoom value before i maximize or minimize the form ?
To tell you the truth i just need to know the old zoom value and re apply it to the maximized or minimized form. I assume that would do it. |

Hi
TImageEnView.OnResize would be best.

Hi
Then VisibleBitmapRect should work (if image is larger than view), or just maths:
Zoom := Previous_Zoom * New_Size / Old_Size;

Let me try one more time :) if i have an image that has a 30 % zoom on an imageenview window, it takes up to 30% of the space. now if i maximize, the image does not adapt to fill the new space at 30%. it will look like more 10 or 15 %. Not sure if am am still making sense. it looks like i may hvae to use the onviewchange event or something like that. |

Hi
I'm not sure I'm following, but you can use the Fit command to make an image fill the screen, or read then write VisibleBitmapRect to make the same area of image show again.

Indeed, it does not change. let me rephrase. If i have my image that fills the screen right now and I maximize, it will not fill the screen anymore. That means if i had a magnification of x, could i get the same x magnification when i maximize or minimize ? Am i making sense ? |

Hi
The magnification (Zoom property) of ImageEnView does not change by default, perhaps you have set one of the auto-zooming properties such as AutoShrink or AutoStretch.
