# How do I change the size of an imported picture in an animation?

My code right now plots a function, and animates an image moving along the curve of the function. I want to reduce the size of the image for this animation but I can't figure out how. If I try to change

image = Import["image.png"]


to

image = Import["image.png",ImageSize -> Tiny]


it just makes the image blurry in the animation. This is the animation code:

Animate[Plot[{f[z]}, {z, 0, 50},
PlotRange -> {{0, 50}, {0, 10}},
Epilog -> Inset[image, {x, f[x]}]], {x,
0, 30}]


Does anyone know how to fix this?

• Just set the image size to a somewhat larger value. – David G. Stork Feb 18 '15 at 3:13

• Although this is dealing with an image, the actual focus lies on the Inset, which is discussed here:Scale Insetted Characters to Plot – Jens Feb 18 '15 at 4:33

Use the fourth parameter of Inset: f = Sin[#] + 5 &;
image = ExampleData[{"TestImage", "Lena"}];

Animate[Plot[{f[z]}, {z, 0, 50}, PlotRange -> {{0, 50}, {0, 10}},
Epilog -> Inset[image, {x, f[x]}, Automatic, 10]], {x, 0, 30}] You can also use Show with the option ImageSize:

image = Show[ExampleData[{"TestImage", "Lena"}], ImageSize -> 40];
f = 5 + Sin[#] + Sin[Sqrt #] &;

Animate[Plot[{f[z]}, {z, 0, 50}, PlotRange -> {{0, 50}, {0, 10}},
Epilog -> Inset[image, {x, f[x]}]], {x, 0, 50}]
