At each step save the resulting png to make it available for further use ie additional scaling in height and width. When scaling in one direction only is intended, the chain link must be broken. Check that the interpolation is set to none if there appear to be odd scaling issues in the new image. Scaling in Gimp can become erratic while working on several files. From a repeat in development for a drop stitch lace design Working through the process with an easily recognized small shape, the often-used small triangle. If the plan is to use Cut to eliminate those same rows, the red cells need to be shifted down to “odd-numbered” rows. In the above, they are on what may be thought of as even-numbered rows of the design. The red cells will change color as well after inversion, making it easier to track the placement of completed choices A result from using the method on a large image may be found in the post on fantasy fair-isle. This is an illustration from another post, where color inversion was planned in the repeat selections, each of which is surrounded by dotted lines that will disappear after they are set. The column is cropped prior to saving the final png for download to the km. In the past, I have used red pixels in an extra column beside the repeat to mark rows that need to be altered. The image is set by clicking anywhere in the window outside of it. If working on parts of the image at a time repeat the steps until the whole image has been processed. While working on any gridded and magnified design motif use the rectangle tool to select the rows that will be altered, make the first selection, and after doing so press and hold the shift key, continue to select specific areas, and then choose color invert in this first instance and the action will be applied to all selected areas. As is often found, the same results may be reached in a variety of ways.Ĭoupling the use of the shift key with rectangle selection and working in high magnification offers additional options in Gimp. It is a reliable, quick way to execute them, especially on large images. 2021: Prior to attempting color separations of any sort, it is useful to have some understanding of how black and white pixels or punched holes relate to knit/ tuck/ slip setting stitch formation and their effect in both single and double bed techniques.Ī recent post explored the use of layers for color separations in Gimp. Notes in post Numbers and GIMP: online punchcard patterns to electronics 2 contain information on printing punchcard designs to scale for tracing and marking cards prior to punching holes. The program now allows for setting pencil pixel sizes to odd and even numbers accurately, eliminating the need to save brushes for sizes missing in previous versions See color exchange notes using the new Fuzzy select tool as opposed to using Color Exchange
