More GIMP charting (3)

These are quick notes from some of my continuing experiments, not explicit how tos or item patterns. Possible lengthening of designs dependent upon knitting technique is not considered; the “charts” were created keeping aspect ratio of original motif. The initial images are copyright free.

from scanned B/W source, 200 pixels X 227

open document

Image_Mode_B&W 1 bit indexed_ Convert

Image Scale 200 wide down to 50

areas were “cleaned up” using single pixel pencil, when satisfactory capture window with grid enlarged for working graph,  or remove grid, export in format for download

this is a partial repeat of a large black and white .png image

working with a smaller, random selection

Open image

Image_Mode_B&W 1 bit indexed_ Convert

enlarge, show grid, decide on accuracy of repeat,  when OK , graph or export and knit, no clean up required for this one

Filter_Map_Tile_magnifying result  will test accuracy of repeat

the motif was a random crop, with obvious issues, more work would need to be done with the original image to isolate the proper section for tiling accuracy to occur

a multicolor image 143 pixels X 112

Image_Mode_Indexed _3 color (manual change from 4 to 3)

Image scale to 100 pixel wide

Enlarge for viewing grid and/or cleaning up; result yields 2 repeats that could be used 50 sts wide each, leaves could use a bit more detail

a partial image grab, pre any “corrections”

if color separations are needed for software that can superimpose  colors and do the necessary color changer manipulations cues a link on color separations for screen printing provides some ideas. Another method

Tools_Selection Tools_By Color Select


Create new document same dimensions


repeat for each color

the results: the flower is actually in the “wrong place” even with what appeared to be same document settings

easier and “on the spot”:

Tools_Selection Tools_By Color Select

Click on color one (flower)


Fuzzy select, click on screen outside of image: the result

Re-open original image

Tools_Selection Tools_By Color Select

Click on color two (leaves)

Edit _ Cut

Fuzzy select, click on screen outside of image: the result
