I have added an ImageView to my LaunchScreen.storyboard in Xcode 13.1 and I have selected my logo but I don't know what to do so that my logo is always in the center of the screen. What can I do so that my logo is always in the center of the screen?
Open LaunchScreen.Storyboard with Xcode .
Set constraints on the ImageViewto determine its position and size .
Enable the options to let it centers in horizontally and vertically .
Drag the square handle to the superview(Container) ,and make them Width/Height eqaul.
Select property menu and modify the Width/Height to make them proportional to superView .
Modify the multiplier to what you want(If the image is full with screen ,set it as 1) .
Save and exit Xcode .
Update
The default content mode is Aspect fit , change it to Scale To Fill.

I am working with a map on which I put an overlay to highlight certain areas, now I want to zoom the map in and out and reposition the overlay so that it is still over the same region. The map is displayed in a JavaFX WebView and the overlay is a polygon that is drawn into a group that is in a pane on top of the WebView.
Now I am trying to calculate the correct position for the overlay, but I can't figure out how. Does someone have some experience there and maybe can point me into the right direction ?
First I'm not some kind of exper for photoshop! I like to put in my picture another picture to be like Lyer, then I go to Layer - Layer Mask - Reveal all... to wipe things I don't want with brush... But I click Alt key and Eyedropper tool appeared with circle and no it not working and I clicked... I don't know how to bring it back... Foreground color and Background color I don't understend that if that is the problem..
You need to click on the white and black mask rectangle on that layer. It will have a link right in front of the rectangle. That rectangle gives you a preview of what you have revealed in white and whats not in black. Looks like a thumbnail of your mask. That will bring it back
I have this picture which I want to display into JavaFX application.
I tested to use setFitHeight and setFitWidth but the image is shrink. I want to zoom the original picture and display only the center of the image keeping the original size. Is this possible?

I use LWUIT 1.4 and I like using it because there are look and feel I prefer in it such as the TabbedPane , ... . So the static field BACKGROUND_IMAGE_ALIGNED_CENTER is not present in class Style in this version. I want to make a LWUIT Image ( png ) as a form's background image and I tried using form.getStyle().setBackgroundType(Style.BACKGROUND_IMAGE_TILE_BOTH); but the problem is that there is a splitting area occupying just above the menu-bar ( its height is visually equal to the menu-bar's height ) : the background image is displayed clearly without any stains but the splitting area , which is something like the upper part of the image , is at the bottom of the screen just above the menu-bar. So how to remove this splitting area ?
I have no idea what you are referring to, an image would be helpful and I would also suggest upgrading to 1.5 which is the only supported version right now.
You can always just set a painter to paint your background in any way you like if the style doesn't act the way you want it to.
I have a panorama page in Landscape mode and a canvas inside it .
I am having multiple images on the canvas , I am handling double click on each canvas element based on the co ordinates (position ) of the mouse click event .
When I click on the screen , the coordinates are staring from the bottom left position (0,0), as it corresponds to Portrait page .
Is there any I can change this , so that it will be adjusted to the Landscape mode .
