In my work, I need to create PowerPoint (ppt) report of similar template. For the report, I need to create various plots in Excel or JMP, save it to folders and finally paste them to ppt. It be great if it is possible to generate ppt report rapidly by using automation. I have created a python interface to powerpoint using com commands hoping it will help to generate the report automatically.
The initial idea is to add command to paste the plots at specific slides and specific positions. The problem with this is that I have to set the position values and picture sizes for each graph in the python script. This become tedious and have to set independently for each report type.
The new idea will be to give the script a scanned template and the script will do the following commands:
- Create a template ppt with the graphs at particular slide, position and size set.
- Rename each object that you need to copy with the keywords such as ‘xyplot_Qty_year’ which after parsing will require a xyplot with qty as y axis and year as x axis. This will then get the corresponding graph with the same type and qty path and link them together.
- See the link on how to rename objects.
- The script will scan through all the slide, getting all info of picture that need to be pasted by having the keyword. It will note the x and y positon and the size.
- The script will then search the required folder for the saved pic file of the same type and will paste them to a new ppt.
The advantage of this approach is that multiple scanned template can be created. The picture position can be adjusted easily as well.
Sample of the script is as below. It is not a fully executable script.
