I'm doing an app with xamarin forms and in a content page I show an image, someone knows how I can do so that when you click on the image, it enlarges and you can zoom in, since the image is a map and It has information that is not visible to the naked eye, thank you.
The best way is like this:
private void OnTapped(object sender, EventArgs e)
{
if (Content.Scale > MIN_SCALE)
{
RestoreScaleValues();
}
else
{
Content.AnchorX = Content.AnchorY = 0.5;
Content.ScaleTo(MAX_SCALE, 250, Easing.CubicInOut);
}
}
void RestoreScaleValues()
{
Content.ScaleTo(MIN_SCALE, 250, Easing.CubicInOut);
Content.TranslateTo(0.5, 0.5, 250, Easing.CubicInOut);
currentScale = 1;
Content.TranslationX = 0.5;
Content.TranslationY = 0.5;
xOffset = Content.TranslationX;
yOffset = Content.TranslationY;
}
