Make Entire Area of New Graphic Editable

Question

Create a new graphic via the menu bar: Graphics -> New Graphic.

The FullForm expression for this graphic is:

Graphics[{}, ContentSelectable -> True, ImageSize -> {480, 360}, PlotRange -> {{0, 4/3}, {0, 1}}]

Using the Drawing Tools palette, the entire area of the newly created graphic is editable:

Suppose now I want to make a new graphic but make it taller; that is, I want a new graphic but with dimension 480 x 800. I can do so with Graphics[{}, ImageSize -> {480, 800}] but only a small part of it is editable.

If I add a PlotRange, for example, Graphics[{}, ImageSize -> {480, 800}, PlotRange -> {{0, 1}, {0, 4/3}}], the editable area increases.

To make the entire area editable, I can change PlotRange to {{0, 1}, {0, 5/3}}.

If I change ImageSize, is there a systematic way to choose PlotRange to make the entire area editable? Other approaches are also welcome.

Answer 1

Adding AspectRatio -> Full fixes this behavior:

Graphics[{}, ImageSize -> {480, 800}, AspectRatio -> Full]

Graphics has AspectRatio -> Automatic by default and this results in addition of non-zero ImagePadding inside of ImageSize but outside of PlotRange and PlotRangePadding and because of the latter PlotRangeClipping -> False alone does not fix this behavior completely. PlotRange -> All is expected to fix this but it does not.

Instead of AspectRatio -> Full one can specify explicit AspectRatio based on ImageSize with the same effect:

Graphics[{}, ImageSize -> {400, 800}, AspectRatio -> 800/400]

Another approach would be to tune PlotRange for ImageSize with AspectRatio -> Automatic. Now the PlotRange occupies all the ImageSize and the area of the graphic and it is completely editable:

Graphics[{}, ImageSize -> {400, 800}, PlotRange -> {{0, 1}, {0, 2}}]

Another approach is to tune up both PlotRange and PlotRangePadding to occupy the complete ImageSize:

Graphics[{}, ImageSize -> {400, 800}, PlotRange -> {{0, 1}, {0, 1}}, 
 PlotRangePadding -> {0, {.5, .5}}, PlotRangeClipping -> False]
