CrossStitchPattern JSON Schema:

See a full example below

{
    "properties": {
        "stitchWidth": 10,
        "stitchHeight": 10,
        "colors": [],
        "patternTotals": {},
        "notes": ""
    },

}

properties - Holds top level information about the cross stitch pattern, such as color and dimension information.
- stitchWidth - A non negative integer representing the width, counted in stitches, of the pattern. This is not required.
- stitchHeight - A non negative integer representing the height, counted in stitches, of the pattern. This is not required.
- colors - An array of Color objects defining all colors used in the pattern.
- patternTotals - An optional PatternTotals object containing the stitch totals (by stitch type and color) for the pattern
- notes - An optional string for any notes/comment about the pattern.
fullStitches - An array of FullStitch objects defining all the full stitches in the pattern.
threeQuarterStitches - An array of ThreeQuarterStitch objects defining all the three quarter stitches in the pattern.
halfStitches - An array of HalfStitch objects defining all the half stitches in the pattern.
quarterStitches - An array of QuarterStitch objects defining all the quarter stitches in the pattern.
backStitches - An array of BackStitch objects defining all the back stitches in the pattern.
longStitches - An array of LongStitch objects defining all the long stitches in the pattern.

Color Schema:

A Color represents a color used in the pattern. The color is made up of one or more strands of Floss. Each floss strand can be a different color/brand, allowing blended colors to be defined.

{
    "colorId": 1,
    "colorName": "Burnt Orange",
    "patternSymbol": "@",
    "flossStrands": []
}

colorId - The ID of the Color of the stitch
colorName - A name for the overall color (since it could be a blend)
patternSymbol - The ASCII character used to represent the color on the pattern visually. This must be unique within all the Color objects in the colors array
flossStrands - An array of Floss objects defining all the strands of floss that make up the color

Floss Schema:

This represents floss of a single color and brand, and by default, a single strand. If more than one strand of the same floss is needed, strandCount can be increased.

{
    "colorCode": "721",
    "colorName": "Orange Spice - Medium",
    "brandName": "DMC",
    "strandCount": 2,
    "hexCode": "0xf27842"
}

colorCode - A string representing the unique brand code for the color. This is often a number, but can be a string like 'ecru' or 'blanc'.
colorName The brand's name for the color
brandName - The name of the brand. See a list of supported Brands here.
strandCount - An integer greater than zero, representing the number of times the strand should be used in the given color. If not given, this defaults to 1.
hexCode - An optional string defining the color's hexadecimal value

FullStitch Schema:

A full stitch covers a single square on the pattern in an 'X' shape. It is the combination of 2 opposing angle half stitches.

{
    "colorId": 1,
    "x": 10,
    "y": 20
}

colorId - The ID of the Color of the stitch
x - The x coordinate of the lower left corner of the stitch.
y - The y coordinate of the lower left corner of stitch.

Example:

FullStitch image

{
    "colorId": 1,
    "x": 1,
    "y": 1
}

A three quarter stitch is simply a QuarterStitch and a HalfStitch combined. Therefore, the half stitch angle and the quarter stitch placement must be given. For a 45 degree angle half stitch top-right and bottom-left are valid quarterStitchPlacement values. Conversely, for a 135 degree angle half stitch top-left and bottom-right are valid quarterStitchPlacement values.

{
    "colorId": 1,
    "x": 10,
    "y": 20,
    "halfStitchAngle": 45,
    "quarterStitchPlacement": "top-right"
}

colorId - The ID of the Color of the stitch
x - The x coordinate of the lower left corner of the space on the grid.
y - The y coordinate of the lower left corner of space on the grid.
halfStitchAngle - The angle of the half stitch which can be either 45 or 135. See the HalfStitch schema for more information.
quarterStitchPlacement - One of 4 values: top-right, top-left, bottom-right, bottom-left indicating the placement of the quarter stitch. See the QuarterStitch schema for more information.

Examples:

ThreeQuarterStitch Top Right

    "colorId": 1,

    "x": 1,
    "y": 1,
    "halfStitchAngle": 135,
    "quarterStitchPlacement": "bottom-right"
}

HalfStitch Schema:

Half stitches comes in two forms. The first form goes between the top left and bottom right corners of the space on the grid forming a 45 degree line. The other form goes between the top right and bottom left corners of the space on the grid forming a 135 degree line. This is why 45 and 135 are the only valid values for stitchAngle.

{
    "colorId": 1,
    "x": 10,
    "y": 20,
    "stitchAngle": 45
}

colorId - The ID of the Color of the stitch
x - The x coordinate of the lower left corner of the square on the grid.
y - The y coordinate of the lower left corner of square on the grid.
stitchAngle - The angle of the half stitch which can be either 45 or 135.

Examples:

HalfStitch 45 Degree

{
    "colorId": 1,
    "x": 1,
    "y": 1,
    "stitchAngle": 45

{
    "colorId": 1,
    "x": 1,
    "y": 1,
    "stitchAngle": 135
}

QuarterStitch Schema:

A quarter stitch spans a quarter of a space on the grid and can be located in either the top-right, bottom-right, bottom-left, or top-left quadrant of a grid space as indicated by the placement field. A quarter stitch is a half stitch cut in half vertically. Therefore, one end of the quarter stitch is always in the center of a grid space, while the other extends to the corner indicated by the placement value.

{
    "colorId": 1,
    "x": 10,
    "y": 20,
    "placement": "top-right"
}

colorId - The ID of the Color of the stitch
x - The x coordinate of the lower left corner of the square on the grid
y - The y coordinate of the lower left corner of the square on the grid
placement - The placement of the quarter stitch within the square on the grid

Examples:

QuarterStitch Top Right

{
    "colorId": 1,
    "x": 1,
    "y": 1,
    "placement": "top-right"

    "y": 1,
    "placement": "top-left"
}

BackStitch Schema:

Back stitches can go laterally, vertically, or diagonally. A back stitch typically moves a full space in any of the possible directions, but 1/2 space fractional amounts are supported for any of the 4 coordinate values. A single back stitch can move across at most 1 grid space in any supported direction. For example if a single back stitch segment spans 1.5 spaces, it must be defined as 2 back stitches, one moving a full space, and one moving a half space.

{
    "colorId": 1,
    "x": 0,
    "y": 0,
    "x2": 1,
    "y2": 0
}

colorId - The ID of the Color of the stitch
x - The x coordinate of the start of the stitch
y - The y coordinate of the start of the stitch
x2 - The x2 coordinate of the end of the stitch

LongStitch Schema:

Long stitches are stitches that span more than 1 space. They can move laterally, vertically, or diagonally (just like back stitches). Long stitch coordinates also support 1/2 space fractional values.

{
