Hi I'm new to blackberry. I want to show the image within the circle using qul.
The easiest way to vignette an image is to overlay it with another image. In Cascades if you create a Container using either DockLayout or AbsoluteLayout you can position multiple ImageView objects on top of one another. The first object will be on the bottom, last on the top, by default. You simply create an image with a transparent viewport of the shape you want. You can scale the image at runtime but you should make it about the size of the largest frame you will need to preserve quality. I used Gimp to create a 786 x 78x pixel image with a white frame and a transparent circle in the middle and saved it to the assets directory as frame.png. I grabbed another image I had easily to hand and create a BlackBerry project with this QML code in an appropriate place:
Page {
Container {
layout: DockLayout {
}
ImageView {
imageSource: "asset:///FusionMap.PNG"
preferredHeight: 360
preferredWidth: 360
}
ImageView {
imageSource: "asset:///frame.png"
preferredHeight: 360
preferredWidth: 360
}
}
}
This is the result:

I am dragging an image to an NSView.
Works fine, except that if I insert the dragged image at the received NSDraggingInfo.draggingLocation, the image is suddenly offsetted from its current drag dimmed drawing.
Indeed, the user has taken the image with the cursor by clicking "somewhere" in the image, there is therefore an offset between the bottom left corner of the image, and the cursor itself. Then, the user drags, and drops the image. If I position the dropped image at the cursor position, the image suddenly shifts...
I tried to use NSDraggingInfo.draggedImageLocation, but the result is even worse. NSDraggingInfo.draggedImageLocation seems to contain an position information that is not at all what Apple describes in the doc.
How can I get the bottom left (or other) point of the dragged image so that I can have a smooth drop and insertion ?
Note: this is a cross-app drag & drop, so I don't have any information at the time the user starts the drag.
Edit: added some information as per comments
The image shifts only when dropped
Here is the code of the performDragOperation func
public func performDragOperation(_ sender: NSDraggingInfo) -> Bool {
let pboard = sender.draggingPasteboard
if let images = pboard.readObjects(forClasses: [NSImage.self],
options: nil) as? [NSImage] {
for image in images {
self.imageDropDelegate?.receive(image: image,
at: sender.draggingLocation)
print("drop point : \(sender.draggingLocation)")
print("image point : \(sender.draggedImageLocation)")
}
}
return true
}
The delegate just creates an image view at the point it is given. The problem is that sender.draggedImageLocation is the poirnt where the cursor is when the mouse up event is detected, which is different from the bottom left corner of the dragged image.
Apple doc says sender.draggedImageLocation should be what I am after, but the prints says:
drop point : (413.18212890625, 458.5313720703125)
image point : (-1438.0, 969.0)
drop point : (439.2493896484375, 443.3453369140625)
image point : (-1438.0, 969.0)
The drop point is indeed the position of the cursor when I release the mouse (drop).
But image point is just completely un-understandable to me.
And I checked that sender.draggingFormation is 1 (so 'none')
I'm trying to create a scroll grid view in which every cell object is tapable.
When a cell object is tapped I want to scale and traslate it to the center of the screen and render it above other cells.
I was able to make it tapable and scale it in its position. Now I want to move the cell object to the center of the screen and render it above other cells.
I've tried many solutions but none of them works.
This is my hierarchy:
This is the grid in normal state:
This is the grid when a cell was tapped:
I'm populating the grid from a C# script dynamically.
void Populate()
{
GameObject cardContainerInstance, cardInstance;
foreach (var c in cardsCollection.GetAll())
{
if (c.IsOwned)
{
cardContainerInstance = Instantiate(cardContainer, transform);
cardInstance = cardContainerInstance.transform.Find("Card").gameObject;
var cardManager = cardInstance.GetComponent<CardManager>();
cardManager.card = c;
cardManager.AddListener(this);
}
else
{
Instantiate(cardSlot, transform);
}
}
}
public void OnCardClick(GameObject cardObject, Card card)
{
Debug.Log("OnCardClick " + card.name);
if (openedCard != null) {
if (openedCard.Number == card.Number)
{
CloseCard(openedCardObject);
}
else
{
CloseCard(openedCardObject);
OpenCard(cardObject, card);
}
}
else
{
OpenCard(cardObject, card);
}
}
void OpenCard(GameObject cardObject, Card card)
{
//cardObject.GetComponent<Canvas>().sortingOrder = 1;
var animator = cardObject.GetComponent<Animator>();
animator.SetTrigger("Open");
openedCard = card;
openedCardObject = cardObject;
}
void CloseCard(GameObject cardObject)
{
var animator = cardObject.GetComponent<Animator>();
animator.SetTrigger("Close");
openedCard = null;
openedCardObject = null;
}
I can't figure out how to move the cell to the center and render it above others.
Note that all is animated using an animator attached to the object itself.
Could anyone help me please? Thank you very much!
EDIT: more details
All cell object have the following hierarchy:
where:
CardContainer is an empty object added to use animator on Card child object
Card is the object itself that has a script, a canvas renderer and an animator
StatsImage is the object that slide out when the card is tapped
Image is a calssic UIImage with Image script, Shadow script and canvas renderer
Other component are simple texts.
EDIT: fix in progress
Trying to apply this suggestions I was able to manage the rendering order (as you see on the image below) but it seems that prevent touch events to be detected on the game object.
I've added a GraphicsRaycaster too and now the bottom horizontal scroll view scrolls again but only if I click and drag a card.
Moreover, with the GraphicsRaycaster, the main grid card still are not clickable and it's possible to open the card only if it is behind the bottom panel (if I click on the red spot in the image below the card behind the panel receives che click)
This is the CardContainer at runtime(note that I'm attaching new Canvas and GraphicsRaycaster on the CardContainer, which is the "root" element):
You didn't clarify whether you are using a sprite renderer or some other method but here is an answer for each.
Sprite renderer:
this the simple one. In each sprite renderer, there is a variable called "sortingOrder" in script and "Order in layer" in the inspector. sprite renderer with sorting Orders that are higher is rendered first. All you would need to do is call:
cardObject.GetComponent<SpriteRenderer>().sortingOrder = 1;
when you click the card, and
cardObject.GetComponent<SpriteRenderer>().sortingOrder = 0;
when you unclick it. I hope that makes sense!
Other Method:
this one is a bit harder and I would suggest that you switch to sprite renderers and it will be much easier and more stable down the road, but I can understand if you have already written a lot of scripts and don't want to go back and change them.
Anyway, all you will need to do Is create two layers: cardLower and cardUpper. then create a new camera and call it topCamera. now under the top camera object in the inspector, change the culling mask (it's near the top) and make sure cardUpper is selected. then change the Clear flags (first one) to "Don't Clear" finally change the depth to 0 (if that doesn't work change it to -2). Now objects in the cardUpper will always be rendered above everything else. You can change the layer through script with
cardObject.layer = "cardUpper"
or
cardObject.layer = "cardLower"
I hope that helps!
Ok, so its pretty simple. So you are going to want to add another canvas component to the game object, and check the override sorting to true. Then use
cardObject.GetComponent<Canvas>().sortingOrder = 1;
to place it in the front and
cardObject.GetComponent<Canvas>().sortingOrder = 0;
to put it in the back.
you are also going to need to put a GraphicsRaycaster on to each of the cardObjects
Ignore my other answer about sprite renderers, they are not needed here
I am trying to use de Image Button on LIBGDX to create a button based on two images.
Using add to second image, works fine, but have one problem.
The images are of different sizes.
Note: I am testing with the same picture to see the result
Is there a way to correct this? Using some scale to the images?
levelsTexture = new Texture(Gdx.files.internal("level1.png"));
levels = new TextureRegion(levelsTexture).split(TILE_WIDTH, TILE_HEIGHT);
ImageButton levels_image = new ImageButton(new TextureRegionDrawable(new
TextureRegion(levels[0][0])));
levels_image.add(new Image (levels[0][0]));
stage.addActor(levels_image);
levels_image.setScale(2f);
The problem:
ImageButton is an extension of the Table class and typically the ImageButton images are set as the background. Using the "add" method for the second image like you did might work kind of, but it behaves differently than setting the background and it also might not be what you want if you want the the second image to also change when you click the button.
The easiest way to add two images to a single ImageButton would be to simply combine the two images in Photoshop (or equivalent) and use that single image on the ImageButton.
The more advanced (and more flexible) method would be to combine the two images programmatically and use this as the background for your ImageButton. This can be done by creating a custom class which extends BaseDrawable and have it take two Images in the constructor. If you want your images stacked on top of each other, set the minHeight of your custom drawable class to be the combined height of your two images. Then override the draw method and draw your two images on top of each other like this:
#Override
public void draw(Batch batch, float x, float y, float width, float height){
img1.getDrawable().draw(batch, x, y, img1.getWidth(), img1.getHeight());
img2.getDrawable().draw(batch, x, y+img1.getHeight(), img2.getWidth(), img2.getHeight());
}
}
The ImageButton takes a Drawable in its constructor, so you can pass this object right into the button when you create it and both of your Images should appear in the button and they will be treated as one.
I've done something similar to make a background for a table using multiple Images and this method works great.
I wrote my own SpriteButton class in which I implement this method for scaling my textures.
private Dimension getScaledDimension(Dimension imgSize, Dimension boundary) {
int original_width = imgSize.width;
int original_height = imgSize.height;
int bound_width = boundary.width;
int bound_height = boundary.height;
int new_width = original_width;
int new_height = original_height;
// first check if we need to scale width
if (original_width > bound_width) {
//scale width to fit
new_width = bound_width;
//scale height to maintain aspect ratio
new_height = (new_width * original_height) / original_width;
}
// then check if we need to scale even with the new height
if (new_height > bound_height) {
//scale height to fit instead
new_height = bound_height;
//scale width to maintain aspect ratio
new_width = (new_height * original_width) / original_height;
}
return new Dimension(new_width, new_height);
}
Then finally you draw the texture with the output dimension as as size to draw.
sb.begin();
sb.draw(this.texture2, this.x, this.y, dim_size_new.width, dim_size_new.height);
sb.end();
So you could technically draw the second image to the size of the the first image, if the first image size is correct.
Your implementation will look different from mine but you should be able to figure it out form here on out.
I have .jpg file that I want to display. I have some Horizontal and Vertical panels and I would like to have it somewhere in there. It is a fairly large image but I would like to make a class or an object that will scale it down for me.
My first thought was to just put it in a Horizontal Panel like so but that does not seem to work as I intended
HorizontalPanel picturePanel = new HorizontalPanel();
picturePanel.setPixelSize(600, 300);
picturePanel.addStyleName("pic");
Css.css
.pic
{
background: url(images/mypic.jpg);
height: auto;
width: auto;
}
I'd like to set the pixel size of an object (panel) and add an image to that panel so that it fits within the bounds (while making sure the ratio is the same as in the picture) so I can programatically add it to a panel somewhere.
public interface MyResources extends ClientBundle {
MyResources INSTANCE = GWT.create(MyResources.class);
#Source("logo.png")
ImageResource logo();
}
in your view class
Image logo = new Image(MyResources.INSTANCE.logo());
add image to panel;
set resolution to your panel and also set the same to your image by using
setPixelSize(int,int);
This works:
Image image = new Image();
Image.setWidth("100px");
image.setUrl('http://127.0.0.1:8888/images/accounts.png');
Loads image form local server and will limit size of image.
I'm wondering about the behavior of {Shape}.attr("fill","url({image.path})").
when applying a fill image to a shape:
public class AppMapCanvas extends Raphael {
public AppMapCanvas(int width, int height) {
super(width, height);
this.hCenter = width / 2;
this.vCenter = height / 2;
...
Rect rect = this.new Rect(hCenter, vCenter, 144, 40, 4);
rect.attr("fill", "url('../images/app-module-1-bg.png')"); // <--
...
}
}
The background image seem to teal accross the canvas behind the shape, thus gets weird positioning (an illustration snapshot is enclosed - i marked the original image borders in red).
This seem to resolve itself in the presence of an animation along a path (a mere path.M(0,0) is sufficiant).
How can i position the fill-image properly in the first place?
The proper way to do this from what I can understand would be to use an SVG pattern declaration to specify the portion and position of the image you would want to use. Then you would use that pattern to fill the rectangle element. Unfortunately, the Raphael javascript library doesn't have support for patterns... so there's no direct way to use an image to fill a rectangle.
