New objects (e.g., text) appear to have random settings. Where does PdfEditor get the settings for a new object?
PdfEditor automatically uses the last setting which was selected or made. If, for example, you click on text with the font size 100 and then create new text, this too will have font size 100. If necessary, prior to creation, click on an object (e.g., text) which has the same settings which you would like to apply to the new object.
