Android Question [B4X] [XUI] CropView how to resize to fullscreen via code or layout?

[scsjc]

I am trying to resize the image to fullscreen (100%x,100%y) with [B4X] [XUI] CropView, and I can't see how it is done.

i use the example from https://www.b4x.com/android/forum/threads/b4x-xui-cropview.94952/#content

Sorry, but I don't understand what exactly you want to do.
Maybe this could help: [B4X][XUI] Fill and Fit images without distortion

The idea is to change the size to 100%x and 100%y of cropview1, but for example:

It happens that if I put it in this size that I show here, and I press the screen above the cropview1 it gives me that error.

and if I put it at 100% x and 100% and the same thing happens when the bmp is smaller than the cropview

Sorry, but I still don't understand what you want to do.
Can you post your project as a zip file?

Here I add the example (it is the same as in https://www.b4x.com/android/forum/threads/b4x-xui-cropview.94952/#content but changing the size of the cropview1 in the layout editor)... I also add a mini video to be seen when the error occurs

I had a look at your project, I get also an error when beginning outsides the CropView.
I have not yet investigated more deeply into it, it is insides the CropView class.
Maybe you could have a look at this [B4X] [XUI] xResizeAndCrop, it's cross platform.

Thank you very much, I will review the xResizeAndCrop, it looks very good.

To fix the error when beginning outsides the CropView: add line 1 and 2

    If SelectionRect.Bottom < 1 Then Return
    If SelectionRect.Right < 1 Then Return
    
    For y = SelectionRect.Top To SelectionRect.Bottom - 1
        TargetBC.SetARGB(SelectionRect.Left, y, a)
        TargetBC.SetARGB(SelectionRect.Right - 1, y, a)
    Next
    For x = SelectionRect.Left To SelectionRect.Right - 1
        TargetBC.SetARGB(x, SelectionRect.Top, a)
        TargetBC.SetARGB(x, SelectionRect.Bottom - 1, a)
    Next

This fix ignore the update when start outside the picture.

A clever and a very nice and useful way to display details from a picture.
