GPL:: Saving JPEG?

[ApeachM]

Hello. I want to use how to save the JEPG files during debugging GPL.

In this code, there seems to exist the method to make some images during GPL.

read_lef ispd18/ispd18_test1/ispd18_test1.input.lef
read_def ispd18/ispd18_test1/ispd18_test1.input.def
gpl::global_placement_debug
global_placement -skip_initial_place

I did gpl::global_placement_debug before calling global_placement.

I can see the snapshots during GPL in GUI, but I don't know how to save them automatically for each pause step. How do I do it?

Also, I want to color for a specific cell, editing c++ code in gpl for my debugging. Is this possible?

I solved it with gui::Gui::get()->saveImage(file_name);. Thank you.

I guess that must be in c++. From tcl you can use save_image. You can look at Graphics::drawObjects for the drawing code.
