css style transform - css-transforms

I wanted to be able to put into effect the css transform property depending on the size of a container with respect to the size of the enclosing window.
With the following code, scaleCameraShutter() is called. Zooming does occur with the re-written code for scaleCameraShutter()and the scaling is accurate.
Here's the only remaining problem = window resizes and so does the container. THEN, I do a reload of the window and the correct zooming totally disappears. In short, the zooming is only temporary, not permanent??
Since this Board thrives on code, the .css specs are at the bottom ...
$(window).bind('resize', function() {
scaleCameraShutter(); // below, container is GLOBAL
});
I call:
function scaleCameraShutter() {
// .width() returns "###px"
// value before scaling
var containerWidth = parseInt( container.width() );
var windowWidth = parseInt( $(window).width() );
var theScale = windowWidth/containerWidth;
var maxContainerWidth = 480;
if (windowWidth > maxContainerWidth)
{
theScale = maxContainerWidth/containerWidth;
}
// Let the Browser pick the parm it accepts:
// IE 10 and Firefox
container.css("-transform" , "scale(" + theScale + ", " + theScale + ")");
// IE 9
container.css("-ms-transform" , "scale(" + theScale + ", " + theScale + ")");
// Firefox
container.css("-moz-transform" , "scale(" + theScale + ", " + theScale + ")");
// Chrome and Safari
container.css("-webkit-transform", "scale(" + theScale + ", " + theScale + ")");
// Opera
container.css("-o-transform" , "scale(" + theScale + ", " + theScale + ")");
}
Last, here's the css:
#container {
position: relative;
margin: 0 auto;
width: 30.00em;
height: 22.50em;
}

As Far as I know, you are passing only one value to SCALE. Try doing one of the following:
scale(x,y) Defines a 2D scale transformation
scale3d(x,y,z) Defines a 3D scale transformation
scaleX(x) Defines a scale transformation by giving a value for the X-axis
scaleY(y) Defines a scale transformation by giving a value for the Y-axis
scaleZ(z) Defines a 3D scale transformation by giving a value for the Z-axis

good luck.

Camera focus an object center

Pick up the exactly center position of object in my code i use onmousedown function inside this function pick the click position i want center an object in the screen
private void OnMouseDown()
{
Camera.main.GetComponent<PanZoom>().thisGameObject = ParentThis.gameObject;
if (_center)
{
Debug.Log("Show Popup");
Popup.SetActive(true);
}
else
{
Vector3 groundPos = GetWorldPosAtViewportPoint(.5f, .5f);
Debug.Log(groundPos);
Debug.Log("groundPos: " + groundPos);
groundCamOffset = Camera.main.transform.position - groundPos;
Debug.Log("Camera pos " + Camera.main.transform.position);
camTarget = Camera.main.transform.position;
float mouseX = Input.mousePosition.x / Camera.main.pixelWidth;
float mouseY = Input.mousePosition.y / Camera.main.pixelHeight;
Debug.Log("Mousex " + Input.mousePosition.x + " : " + Camera.main.pixelWidth + " Mousey " + Input.mousePosition.y + " : " + Camera.main.pixelHeight);
Debug.Log("Mx " + ParentThis.transform.localPosition.x + " My " + ParentThis.transform.localPosition.y);
Vector3 clickPt = GetWorldPosAtViewportPoint(mouseX, mouseY);
camTarget = clickPt + groundCamOffset;
Go = true; // For Camera movement //!?
}
}
I would in this case advise you to read more about Cinemachine, as it has functionality where you can make it change to look at a camera target. Please note that Cinemachine must first be installed via the package manager in Unity.

Pixel perfect 2d camera in unity

I have a very simple script that updates my orthographic camera on a given resolution so that it accurately scales the view to be pixel perfect.
Here is some relevant code:
OrthographicSetting get_override(int size)
{
return Overrides.FirstOrDefault(x => x.OrthographicSize == size);
}
void update_ortho()
{
m_last_size = Screen.height;
float ref_size = (OrthographicSize / PixelsPerUnit) * 0.5f;
OrthographicSetting or = get_override(m_last_size);
float ppu = or != null ? or.PixelsPerUnit : PixelsPerUnit;
float ortho_size = (m_last_size / ppu) * 0.5f;
float multiplier = Mathf.Max(1, Mathf.Round(ortho_size / ref_size));
ortho_size /= multiplier;
this.GetComponent<Camera>().orthographicSize = ortho_size;
Debug.Log(m_last_size + " " + ortho_size + " " + multiplier + " " + ppu);
}
[System.Serializable]
public class OrthographicSetting
{
public int OrthographicSize;
public float PixelsPerUnit;
}
OrthographicSetting get_override(int size)
{
return Overrides.FirstOrDefault(x => x.OrthographicSize == size);
}
With this, i can specify a set of overrides for every resolution.
My current setup is using 100 pixels per unity unit. All of my sprites use point filtering with no compression. Yet i still get strange results. 90% of the sprites render fine, but some seem to be rendering incorrectly.
Here's a screenshot to illustrate:
I may have solved the problem. I was using a sprite shader with pixel snap turned on. if i turn off pixel snap the problem seems to more or less go away. I still get the occasional problem with game objects that aren't in "nice" positions, i dunno how to avoid that problem though...

Underlining with pdfnet results in different line thickness

The code that i use for underlining a selection of text. I begin calling the addUnderline() method, the other methods are helper methods.
private pdftron.SDF.Obj CreateUnderlineAppearance(pdftron.PDF.Rect bbox)
{
ElementBuilder builder = new ElementBuilder();
ElementWriter writer = new ElementWriter();
builder.PathBegin();
builder.MoveTo(bbox.x1, bbox.y1);
builder.LineTo(bbox.x2, bbox.y1);
Element line = builder.PathEnd();
//Set color attributes for the line...
line.SetPathFill(false);
line.SetPathStroke(true);
GState gs = line.GetGState();
gs.SetStrokeColorSpace(ColorSpace.CreateDeviceRGB());
gs.SetStrokeColor(new ColorPt(0, 0, 0)); // black
gs.SetLineWidth(2);
writer.Begin(m_document);
writer.WriteElement(line);
pdftron.SDF.Obj stm = writer.End();
builder.Dispose();
writer.Dispose();
// Set the bounding box
stm.PutRect("BBox", bbox.x1, bbox.y1, bbox.x2, bbox.y2);
stm.PutName("Subtype", "Form");
return stm;
}
public Annot CreateUnderlineAnnot(pdftron.PDF.Rect rect)
{
Annot underlineAnnot = Annot.Create(m_document, Annot.Type.e_Underline, rect);
underlineAnnot.SetAppearance(CreateUnderlineAppearance(rect));
return underlineAnnot;
}
public void AddUnderline()
{
if (m_document != null)
{
PDFViewCtrl.Selection selection = m_pdfViewer.GetSelection();
int pageNumber = selection.GetPageNum();
double[] quads = selection.GetQuads();
int numQuads = quads.Length / 8;
if (quads.Length % 8 == 0) //must have at least 8 points to be valid
{
Console.WriteLine("GetRectsFromQuads - numQuads: " + numQuads.ToString());
for (int i = 0; i < numQuads; i++)
{
Rect selectionRect = GetSelectionRect(ref quads, i);
//Console.WriteLine("GetRectsFromQuads - aRect: " + rectX1.ToString() + " | " + rectY1.ToString() + " | " + rectX2.ToString() + " | " + rectY2.ToString());
Annot underlineAnnot = CreateUnderlineAnnot(selectionRect);
m_pdfViewer.AddUnderlineAnnotationToPage(underlineAnnot, pageNumber);
//m_pdfViewer.Refresh(); --> to see how this algorithm works when debugging
}
m_pdfViewer.RefreshAnnotations();
}
}
}
You can see in the image if you look closely that some lines are thicker or thinner than others. Is this fixable? by the way, when i zoom in/out the problem is gone...
You need to set the following on your pdf view control:
PDFViewCtrl.SetThinLineAdjustment(true, true);
That will remove the aliasing on the lines, and mean all lines that are 1.5px are 1px, and so on. See here: https://www.pdftron.com/pdfnet/mobile/docs/WinRT/html/M_pdftron_PDF_PDFViewCtrl_SetThinLineAdjustment.htm

How to change the position of a tooltip div in leaflet marker on dragging the map

I have some markers in the leaflet map. On clicking a marker a tooltip div appears to show a chart and some information. If after that I drag the map the tooltip window remains in the same position but the markers position is changed.
I am using the following function to change the marker position
function update() {
markers.attr("transform", function(d) {
if(d.code==clickedcode)
{
console.log((map.latLngToLayerPoint([ d.lat, d.lon ]).x) + "px , "+(map.latLngToLayerPoint([ d.lat, d.lon ]).y - 80) + "px");
div.style["left"]=(map.latLngToLayerPoint([ d.lat, d.lon ]).x) + "px";
div.style["top"]=(map.latLngToLayerPoint([ d.lat, d.lon ]).y - 80) + "px";
}
return "translate("
+ map.latLngToLayerPoint([ d.lat, d.lon ]).x + ","
+ map.latLngToLayerPoint([ d.lat, d.lon ]).y + ")";
});
}
I am also trying to change the div position. But its not changed. How can I change the div position along with the change of position of map due to dragging.

MenuItemLabel callback not working, never calls the callback, but the MenuItemImage works

Size visibleSize = Director::getInstance()->getVisibleSize();
Vec2 origin = Director::getInstance()->getVisibleOrigin();
Vector<MenuItem*> menuItems;
auto label = Label::createWithTTF("Space Combat", "fonts/Marker Felt.ttf", 24);
label->setPosition(Vec2(origin.x + visibleSize.width/2,
origin.y + visibleSize.height - label->getContentSize().height));
this->addChild(label, 1);
auto closeItem = MenuItemImage::create("CloseNormal.png", "CloseSelected.png", CC_CALLBACK_1(MainMenu::menuCloseCallback, this));
closeItem->setPosition(origin.x + visibleSize.width - closeItem->getContentSize().width/2,
origin.y + closeItem->getContentSize().height/2);
menuItems.pushBack(closeItem);
auto playLabel = Label::createWithTTF("Play", "fonts/Marker Felt.ttf", 24);
playLabel->setPosition(Vec2(origin.x + visibleSize.width/2, origin.y + visibleSize.height - label->getContentSize().height *2));
auto playItem = MenuItemLabel::create(playLabel, CC_CALLBACK_1(MainMenu::menuPlayCallback, this));
menuItems.pushBack(playItem);
auto menu = Menu::create();
menu->addChild(closeItem);
menu->addChild(playItem);
menu->setPosition(Vec2::ZERO);
this->addChild(menu, 1);
auto sprite = Sprite::create("HelloWorld.png");
sprite->setPosition(Vec2(visibleSize.width/2 + origin.x, visibleSize.height/2 + origin.y));
this->addChild(sprite, 0);
return true;
}
The above code will call my menuCloseCallback when the MenuItemImage is clicked on, but won't do the same for the MenuItemLabel.
Figured it out. I was positioning the label, but the menu item was being placed in the default location of 0,0 anchor 0,0. Once i added the label and positioned the menu item, all was well.
