Created attachment 172735 [details] PDF document with example of Rectangle tool Rectangle Tool: Add Option to XOR the Colour SUMMARY It is sometimes useful to highlight an entire paragraph or segment of text. The rectangle tool offers a nicer geometry than the Highlighter tool. However, the color is simply added over, making it more difficult to read due to the poor contrast. Implementing a XOR-variant of the Rectangle tool (similar to the Highlighter tool) would improve the visibility of the text. Note: The attached pdf document has various Headings which are "embedded" in the main text (see on page 2 and following pages). This defies the purpose of the heading (but this is in the scope of the journal)! I used the Rectangle tool to mark these headings: the geometry is better than with the Highlighter tool. STEPS TO REPRODUCE 1. Open attached pdf document 2. See examples on page 1: Highlighter vs Rectangle 3. See examples on page 2: Rectangle tool for hidden Headings OBSERVED RESULT The text is partly obscured with the Rectangle tool: very poor contrast. EXPECTED RESULT Implement option for Rectangle tool that behaves like the Text highlighter: the colour needs probably to be XOR'ed. SOFTWARE/OS VERSIONS Windows: 10 ADDITIONAL INFORMATION Note: The Rectangle tool may also have a nicer geometry with text with superscripts: e.g. the document contains a lot on expressions like "CD4+", "CD8+", where the "+" is superscript. Other documents may include references as superscript. Highlighting an entire paragraph using the Rectangle tool may look nicer in these instances.
