With iOS Auto-Layout each element inside a superview can have a relative size (e.g. element A is twice as wide as element B, element C is half as wide as element A...).
What I want to do differs a bit from the approach described above.
Imagine each element has an absolute width. The sum of all widths is less then the width of their superview. According to the element's weight value (A.weight = 2; B.weight=1; C.weight = 1;), I would like to distribute the remaining space. Is their any possibility to get the remaining space, although the width of the superview is unknown?
Thanks in advance!

In my SVG picture there are some text labels that are displayed dynamically in top part of the image. In some cases (i.e. smaller screen size, bigger font size), they partially disappear outside the vievBox (like if overflow: hidden; was set) - see the picture (the long word in the middle is the overflowing label).
My idea is to scale down the image so that the labels are visible. How to achieve this?
In my case, I had quite wide bottom margin, so I could afford moving the whole image down to uncover the top part.
Final solution was wrapping the whole image with <g transform="translate(0,10)">.
The first value refers to left-right movement, the other one to up-down (positive values move the image down, negative - up).
I am having a space with some defined sizes and I have item with also some sizes and I need to create something that will take item width and compare if it fits to all sizes of space, same for depth and height of the item and none of the size can't be reused, I mean you can't bend item to fit so if item Height match any size of space then width can't fit to the same side.
Here are my Sizes:
Thank you for any idea how to solve this, using formulas.
Just in case the dimensions aren't always sorted smallest to largest:
Seems to work for your example:
For drawing filled shapes like Rectangle, Eclipse need two values width and height (converted from int to float).
There's an enum,
Public enum Sizes : int
{
One=5,
Two=10,
Five=10,
Seven=12,
Ten=15,
}
In terms of drawing a Square of One, should be of width and height of 5. Which is straight forward. However when drawing Oval Shapes and Rectangular shapes above one value isn't sufficient.
Is there a way I could define another float value? So when compared for Ten, it can provide 15 for Width and 10 for Height...
Or does it mean, there should be two enums, one for Width and one for Height?
EDIT to provide more background info:
There's an UI which allows users to create certain shapes.
User inputs are: Shape Type (Line, Rectangle, Eclipse), Points, Size (but this size doesn't exactly reflect the size of the shape. e.g. 10 is a capacity. Capacity 10 must draw 15px Width and 10px height Rectangle/Eclipse).
Line doesn't take Size into account as it is drawn using the Points input. The rest of the shapes do take Size into account. So this is where I need to check the Size(capacity) parameter and issue the correct Width and Height to be drawn.
Per the example in the Masonry documentation, http://masonry.desandro.com/options.html, I centre my Masonry layout by setting isFitWidth = true, and setting {margin: 0 auto} on the Masonry container.
When I have loads of items to display this is a really nice solution. For example, let's say my viewport is just over 5 columns wide, I will see all the items laid out, 5 to a row, and the whole container centred within my viewport. Lovely.
The problem arises when I have less than 5 items. In this case, the container remains centred in the viewport, but it shrinks to fit the number of items. So if I have, for example, two items, I will have two columns in the middle of the screen, with one item each.
What I would like to see is the container maintain is size (in this example, 5 columns), and remain centred, and lay the content out LTR (in my case).
I have experimented with media queries and setting a minimum width for the container based on the viewport. This looks like it will work, but it's messy - I don't fancy having to update the media queries (including recalculating all the gross container widths) each time my column size changes. (I'm sure users will want some changes).
Another solution might be to add some fake items to the content and set their visibility to hidden, but this is not exactly elegant either.
Is there a more simple solution that I'm missing?
One additional point - I am stamping some items in place too, top left and top right. I don't think this should affect any solutions.
OK, So the only way I could find to do this effectively was to use media queries. I setup a spreadsheet to help recalculate things when I changed column and gutter sizes. Here's the variables and equations, in case they are helpful:
If:
WC = Width of column
WG = Width of gutter
N = Number of columns
CON = Width of container
Then:
CON = N*WC + (N-1)*WG
You can set up a spreadsheet and experiment with WC and WG, and a range of N=1...10 This will give you the size of CON for each value of N. The width of the viewport needs to be CON plus any horizontal margin and padding on CON (or its parent).
To set media queries I took the approach that the container should be as wide as possible, but still neatly accommodate exact columns. So, for example, if the viewport can accommodate 5 columns, (but not quite 6), I set the corresponding min-width on CON. This leave the container neatly centred.
By way of example, here is one of my media queries:
#media (min-width: 996px) and (max-width: 1361px) { .content-container { min-width: 966px; } }
I hope this is helpful to someone. I'll leave the question open for a few days in case there are other solutions forthcoming.
I have tspan element with some text in it. I specified some font-size for it as well. In addition I have parent's box size, i.e. width and height. So now I'd like my text to fit the box with the specified width and height.
One of the options I have is manually calculate string width and height (but it became more complicated in case of different fonts and browsers).
So is there any other way in SVG to resize tspan to necessary sizes? Please note that I want text font size to be changed properly, i.e. so text will be displayed in max font size and any single char from it will be visible.
Well, I've came up with the following solution - have absolutely positioned div element outside of visible area. Apply all fonts and other-related styles (except font size) from tspan to that div, put text into the div. Next try different sizes (you can use binary search for better performance) and measure div size. Once max font size found - apply it along with the text to tspan.
