Files and images

Attaching files, reading images and tables, and showing a matrix as a picture.

A worksheet carries the files it reads. Use Files on the toolbar to attach one: an image adds a readImage line, and other files are read by name with readTable or readWav. The files are saved inside the worksheet.

Image on the toolbar shows a matrix as a picture: gray levels 0 to 255, or red, green and blue side by side. Picture… puts a picture from a file on the page, as it is.

Save writes a .mathmath file. Open reads those and Mathcad .xmcd worksheets.
