Current parameters
The table below describes the parameters used for generating the pattern.
| parameter | value | description |
|---|---|---|
| color_number | 10 | number of different colors or fabrics |
| colorspace | YUV | [advanced] colorspace to use in reducing the number of colors in the original picture (some examples are YUV, RGB, HSV) |
| colorspace_max_colors | 500 | [advanced] maximum number of colors returned after colorspace reduction |
| finished_size | 37.5 x 17.25 | finished quilt size, in inch |
| grid_block_size | 8 | block size in tiles (i.e. 8 for instructions for blocks of 8x8 tiles) |
| img_filename | bluemountain.jpg | picture file to process (.jpg) |
| img_height | 871 | height in pixel of the image |
| img_width | 1875 | width in pixel of the image |
| tile_number_height | 23 | number of tiles across the height of the picture |
| tile_number_width | 50 | number of tiles to have across the width of the picture |
| tile_size | 0.75 | size in inch of each square tile (i.e. 2 for 2x2” tiles in finished quilt) |
| tile_width | 37 | tile width in pixel |
Color reduction
Pictures contain often hundreds of colors, many very close in shades. It is necessary to simplify the color universe of the original picture before calculating the number of occurance of each color. Without that simplification, the dominant color shades might overwhelm the other colors and bias the final colorscheme.
Different pictures might behave differently with different colorspace
reduction, try another colospace in the
config.yaml file if the colors look off after reduction.
The maximum number of color after reduction
(colorspace_max_colors in the file
config.yaml) can also be adjusted.

Overview of tiled picture
Below is the result of tiling and color-clustering, to have at most 10 colors.
For easier quilt assembly, the full picture is divided in 8x8 tiles blocks.
Fabric requirements
Below is the color swatch with number of tiles needed, and translated into yardage. Fat quarters are 18x22”. Yard width-of-fabric is 42”. The yardage includes a 1/4” seam allowance.
Cut the specified number of 1.25” squares per color.

General assembly remarks
For easier assembly, first sew together 8 tiles x 8 tiles blocks, then sew rows of blocks, and finally sew rows together.
Blocks assembly
