Android Question Gravity.FILL question

[clooney48]

Hi!
I don´t get it! I want to fit the image which I load from "/100Media/" on the screen. It is always too large. What is wrong with this code?

  Dim Bitmap1 As Bitmap
   
   TouchImageView1.Initialize("TouchImageView1")
   Activity.AddView(TouchImageView1, 0, 0, 100%x, 100%y)
   
   TouchImageView1.MinScale=0.5     
   TouchImageView1.MaxScale=1.5       
   TouchImageView1.TranslatePadding=64dip   

   Bitmap1.Initialize(File.DirRootExternal & "/DCIM" & "/100Media/", DBUpdate.vbild)
   TouchImageView1.SetBitmap(Bitmap1)
   TouchImageView1.Gravity = Gravity.FILL
   SourceImageRect.Initialize(0, 0, Bitmap1.Width, Bitmap1.Height)
   TouchImageViewRect.Initialize(0, 0, TouchImageView1.Width, TouchImageView1.Height)

And how does it work for an image in landscape mode??

Setting Gravity to Gravity.FILL will make the image fill the ImageView. However I'm not familiar with the implementation of TouchImageView.

Hello

Add this:

TouchImageView1.ScaleSrcRectToDestRect(SourceImageRect, TouchImageViewRect, "CENTER")

below the:

TouchImageViewRect.Initialize(0, 0, TouchImageView1.Width, TouchImageView1.Height)

If you want the image weighs less memory, change this:

Bitmap1.Initialize(File.DirRootExternal & "/DCIM" & "/100Media/", DBUpdate.vbild)

for this:

' plays with the 100%x and 100%y to put it to your liking.  I have put 300

Bitmap1.InitializeSample (File.DirRootExternal & "/DCIM" & "/100Media/", DBUpdate.vbild,100%x,100%y)

Hi!

Thanks, but unfortunately doesn´t work.
And what is also funny: when I use 72% for x and y in TouchImageView1 the image is much smaller than the view, when I use 74 % it is much bigger!?

best regards

Hi bgsoft!

It works now with your changes after I removed this line:

TouchImageView1.Gravity = Gravity.FILL

Thank you!
