C++ (Cpp) Doc::resetTransformation Examples

Example #1

File: set_mask_position.cpp Project: aseprite/aseprite

void SetMaskPosition::setMaskPosition(const gfx::Point& pos)
{
  Doc* doc = document();
  doc->mask()->setOrigin(pos.x, pos.y);
  doc->resetTransformation();

  doc->notifySelectionChanged();
}

Example #2

File: cmd_mask_content.cpp Project: aseprite/aseprite

{

  {
    ContextWriter writer(context);
    document = writer.document();
