I'm trying to create slidingup animation in android application to change between two view of layout.
I've tried from this tutorial
but the second screen didn't come like what I want.
I want the second layout to come like a wipe animation, like the following picture at the bottom
Refer this:
https://android.googlesource.com/platform/frameworks/base/+/ab51002847ea3dcdc0ba14eb330ab9ec292a9789/packages/SystemUI/src/com/android/systemui/statusbar/phone/PhoneStatusBar.java
In the above code, focus on the animateCollapsePanels method
I was able to implement a similar transition by using a clipping Path. Because I didn't want my transition to rule out the use of Layouts in the clipped view, I implemented the clipping at the Layout level following this answer: Custom Layout that rounds the corners of its content
The clipping is no anti-aliased and you would need to do use instead PorterDuff and XferMode based solutions otherwise, but for a linear wipe animation like you're describing, clipping in the layout will achieve what you want. Basically you're doing a linear reveal whereas the accepted answer I linked does a circular clip.

So I have an instanced scene that is supposed to be the child of a colour rect in my tree. I want to randomly generate the nodes, but I also want parts of the view to be cut off if the texture no longer is above the main section. I know you can render nodes below their parents, but I don't know if stopping part of them from rendering is physically possible.
In this image I want the bottom circle to remain the same, but the top circle to not show anything above the dark purple box
This is the node tree in the editor
Is there any way to do this directly, or am I gonna have to use a viewport of some variety?
I believe what you want is to set rect_clip_content to true on the ColorRect (or whatever Control). Making invisible any part of its children outside of it.
From Godot's documentation:
bool rect_clip_content
Enables whether rendering of CanvasItem based children should be clipped to this control's rectangle. If true, parts of a child which would be visibly outside of this control's rectangle will not be rendered.
If what you want is the opposite, perhaps you can use z_index to have something render on top, occluding the parts you don't want visible.
There is also a trick you can use with lights (including 2D lights):
Make a light that matches the area you want things to be visible.
Set a custom material that will be transparent by default, but visible on the light pass. The simpler way to do this is to set the light_mode of the material to "Light Only". You could also do it with a custom shader instead.
Making something disappear with light, in 2D, is impossible. In 3D, you can use flags_use_shadow_to_opacity. That is how you make a shadow catcher.
But, there is one more trick: you can use a mask. This should give you full control of when to show or hide things. So, if none of the above solutions works for you, use a mask. I have an explanation in a different answer. See also: How to crop sprite in a non-rectangular form?.

is it possible to create a stroke with a dynamic width with SVG? I want to achieve a Calligraphy look like here, here or here.
Is this even possible? It seems customization of strokes in SVG is fairly limited. Even gradients in strokes seem to be non-trivial (see here).
There is a proposal to add into SVG standard a mechanism, that does exactly what you want:
http://www.w3.org/Graphics/SVG/WG/wiki/Proposals/Variable_width_stroke
http://lists.w3.org/Archives/Public/www-svg/2013May/0041.html
There's even an example implementation available here:
https://rawgit.com/birtles/curvy/master/index.html
It is, however, by no means official and we cannot be even sure it'll ever be.
Until then you'll need to stick to Bezier curves and object filling:
You can also use calligraphic fonts, for example - Tangerine available on Google CDN:
This approach requires less work since you don't need to draw everything from scratch, but then again, using third party fonts leaves you with little control over the final result.
You can't dynamically adjust the stroke of a path element. However you could draw a path, use a fill color on it instead of stroke, then double back upon the letters at a slight distance away from the original line.
Also, if you are using the SVG on the web then you can use css fonts on text elements. There are some pretty good cursive fonts that you can use for free... just check google web fonts.
My goal is to create something like the arrow from car that indicates the speed of the car. My problem is that I do not know what is the best practice for moving the green arrow. I have an image arrow.png and I guess I need to manipulate with the place that the picture is shown and with the rotation of the image.
Can someone point to me some guidelines ?
My basic idea is to have a relative layout for the background and to have one image view that will change the position, but the part changing position is little unclear to me. And I do not think that is good idea to play with layout params and margins...
I would probably extend ImageView then override your onDraw method and use canvas.rotate() to rotate the arrow depending on your app state.
I'd like to improve upon jQuery's dialog code by using CSS-sprites, and thus also add animations of the dialog borders.
To do this, i'd like all the artwork to be in 1 png file, a css sprite.
My problem is that in order to support a dialog that maximizes to 2 or 3 monitors, i think i'd have to put 5000px wide / high border graphics in the css sprite file. Because i can't find a way to resize a selected portion of a css sprite image.
Basically i want to resize from the sprite image a region (t,l,w,h) to a DIV or IMG on my page with a different width and height.
I'd like to know, is this even possible? It seems background-position does not support this at all.
I've tried the first solution in How can I scale an image in a CSS sprite, but could not get it to work using that.
I've tried using the new background-size property in conjunction with background-position, but that also does not produce the results i want.
Spent another few hours twiddling with css, but could not get sprites to work for dialogs.
But my animated dialogs don't need many frames (not unless you want to put actual video as a dialog backdrop online), so for the dialog theme i'm designing now i have 8 312x312 png's as frames, 8 requests, 386kb total. Just enough to create a glowing animation for when the dialog is in a "highlighted" state. It's do-able.
I'm using the technique from How can I scale an image in a CSS sprite
See http://mediabeez.ws in about a month for the opensource release of animated dialogs.
I will be developing and testing this standalone component when it's used by my own homegrown CMS, so it will have the ability do be themed, dragged and dropped, things like that.
I am working on a SVG application and now want to let a user resize an object using draggable corners, very much like in SVG-edit (http://svg-edit.googlecode.com/svn/trunk/editor/svg-editor.html).
The functionality should work as follows: The user selects an SVG object, drags it to the main ‘canvas’ and once on the ‘canvas’, four corners on the outside of the object appear, the user can drag on each of the corner points & drag to enlarge the object. The objects will be rectangular in shape and created using paths, not using the SVG ‘rect’ function.
Would anyone have any suggestions as to how this should be implemented?
Thanks in Advance
You could take a look at some existing open source implementations. svg-edit is one which you already mentioned.
To showcase a tool that I developed, I wrote a demo which implements this functionality. This which may serve as a simpler and more restrictive example than svg-edit, as it doesn't do too much other than allow you to draw rects and circles, and rotate/translate/scale them.
I have edited jquery to make rect draggable, recently put them in a g and lost this functionality. The g doesn't contain the position data.
Might be possible to bubble down to the children elements.
