The meaning of those terms varies from application to application, but I ended up choosing for my beloved Cin the following ones:
to RESIZE: to reduce, enlarge o reshape the outline of an image preserving the absolute measures of the distances inside it. Part of the image can be cropped or blank bands can result. Example: I can resize the rectangular image of my pizza on the table and make it a square around the pizza to hide knife and fork. My pizza will always be of the same size. to SCALE: to reduce or enlarge an image proportionally, preserving the ratio of the distances inside it. The image is modified whole; no parts of the image are cropped, even if they may be not displayed when beyond the canvas size. Blank bands can result. Example: I can enlarge or reduce the whole rectangular image of my pizza on the table, saving my knife and fork and making my pizza bigger or smaller depending on how hungry I am. to CROP: to remove portions of an image to eliminate unwanted areas or to give it another aspect ratio. Note: Since these definition are newbie-made, they may be inaccurate. > well... i think the "canvas size" should be the resolution > of the entire composition, like in a painting or (ideally) in cinema. > and that should well be identical with the output file... right? Right when you keep the same standard. Wrong when you change from PAL to NTSC: the project output shape is different from the canvas shape. The possibility to set their size separately would make the standard conversion _inside_ Cin easier. Ciao ciao!
