<meta content="This test checks that the process of repeating the tile when 'border-image-repeat' is 'round stretch'. Thanks to a specially crafted rectangular border-image, we check how the sliced border-image is, in the first-subtest, rescaled down horizontally (top and bottom sides), and is, in the second-subtest, rescaled up horizontally (top and bottom sides). In both subtests, the border-image in the vertical axis (left and right sides) are stretched." name="assert">

"

The first keyword applies to the horizontal scaling and

tiling of the top, middle and bottom parts, the second to

the vertical scaling and tiling of the left, middle and right parts

border-image-slice: 64 fill; /* the center will be black */

border-image-source: url("support/4bicolor-squares.png");

display: inline-block;

image-rendering: pixelated; /* attempt to overcome antialias fuzziness */

margin-right: 1em;

}

div#first-subtest

{

height: 192px;

width: 96px;

/*

96px divided by 64px == 1.5 which is rounded up to 2.

So, the image should be 96px divided by 2 == 48px

wide. That means that the top and bottom bicolor

(yellow and purple) images should be 48px wide,

therefore rescaled down, from sliced 64px to 48px.

The left and right sides should be stretched from

sliced 64px to 192px (3 times).

*/

}

div#second-subtest

{

height: 128px;

width: 80px;

/*

80px divided by 64px == 1.25 which is rounded down to 1.

So, each image should be 80px divided by 1 == 80px

wide. That means that the top and bottom bicolor

(yellow and purple) images should be 80px wide

therefore rescaled up, from sliced 64px to 80px.

The left and right sides should be stretched from

sliced 64px to 128px (2 times).
