If I use the TMSFMXRichEditorFormatToolBar to insert a jpg image that is 1291x517 for example, then save and restore it, the image is resized to be square. Even if I attempt to resize it, the new size does not stick. It seems to always set it to be this in the rtf:
{\pict\pngblip\picw12650\pich12650
I tried both the Save/load buttons on the TTMSFMXRichEditorEditToolBar as well as using TMSFMXRichEditorRTFIO's Save/Load functions.
