Each command set block will have a name and consist of commands and comments. The command set will be read and parsed into a data structure.Let’s touch upon the main ideas that we are going to use to implement the macro recording and execution scheme that we can use to capture and run a set of commands. Macro Implementation – in Broad Strokes ¶ In this case we made the grid spacing based on a percentage of the image size rather than a fixed size in either inches, pixels, or cm.

The ability to save the macro code fragments allows us to build up a library of editing shortcuts that will not only save time, but do the job better than you could be simply pushing the buttons. The tool will access the “macro” code fragment using the name we assigned through a pull down menu. The tool we are writing in this tutorial will allow us to copy this code fragment into a text file, add a name and optional comments, and access it through a menu widget so we can rerun this code fragment on other images. If you watch the image as you enter the commands and have the Grid turned “ ON” you will see the grid spacing on the active image change as we execute these commands. gimp_image_grid_set_style ( theImage, GRID_ON_OFF_DASH ) gimp_image_grid_set_spacing ( theImage, gridSpacing, gridSpacing ) > pdb. gimp_image_grid_set_offset ( theImage, centerX, centerY ) > pdb. height / 2 > gridSpacing = max ( theImage. We could enter the following code fragment in the Gimp “Python Console” (under the “Filters” pull down menu) to set the grid up. Suppose we wanted to set up the grid spacing so that it is centered on the image, is a square grid, is scaled so there are 24 grid blocks in the ‘long’ dimension, and is an on-off dash pattern. An introduction to Macros ¶īefore we dive into a description of the code, let’s take a brief walk through the process of capturing and running a “Macro”. * Hopefully it is easy to adapt it to Apple OS as well.
It would probably be helpful to read through the earlier tutorial for introductory example. This tutorial will use some of the concepts covered in an earlier tutorial “ Automated Jpg to Xcf”.
We are not going to cover python programing as it is already well documented.

The details of how to setup and run the example code and what the automation example is supposed to accomplish will be covered in appendices to the tutorial. Hopefully we can keep the focus on the concept without getting lost in the details of the included example. The main body of this tutorial will be discussing the ideas behind automating the editing process. If the coding style seems a bit rough, I apologize, I am not a programmer. The goal of the tutorial is to provide and explain a working example. These automation tools are examples so please modify them to suit your needs. Taking over the button pushing and book-keeping chores allows the user to focus on the more creative part of the editing process. The goal of these functions is to provide tools that speed up the editing process, make the editing process more repeatable, and reduce the amount of button pushing the user has to do.
#Stroke path gimp 2.8.22 portable#
The code for this tutorial is written using Gimp-Python and should be platform portable – able to run on either Linux or Windows operating systems. The second function is a set of Automation Tools to capture and run a “Flow” or “Process”. The first function is a tool to capture and execute “Macro” commands. This tutorial will describe and provide examples for two types of automation functions.
