# Rectangle with rounded edges

Inspired from :

Fit an image within a Rectangle [] in Graphics

I would like now to fit an image within a Rectangle[] with rounded edges as shown in the example below :

Is it possible ?

• You need to use RoundingRadius as an option in Rectangle like Graphics[Rectangle[{0, 0}, {2, 1}, RoundingRadius -> 0.3]].

Text piece:

 txt1 = Take[
ExampleData[{"Text", "LoremIpsum"}, "Lines"], {1, -1, 2}][[1]] //
StringTake[#, 330] &;


Image piece:

 pic = Import["http://dailytechgadgets.files.wordpress.com/2011/02/old-ferrari.jpg"];


And Heike's code for rectangles:

 rec[ll_, ur_, pic_] :=
Module[{crop, boxrat},
boxrat = #2/#1 & @@ MapThread[Abs[#2 - #1] &, {ll, ur}];
crop = ImageCrop[pic, Transpose[{ImageDimensions[pic]}],
AspectRatio -> boxrat];
Inset[crop, Min /@ Transpose[{ll, ur}], {Left, Bottom},
Abs[ur - ll]]]


and Heike's code again for putting all together -- just adding RoundingRadius to rectangle objects and commenting out lines that produce lines--:

 Graphics[{EdgeForm[{Thickness[0.005], Black}], FaceForm[White],
Rectangle[{0, 0}, {160, 90}, RoundingRadius -> 4],
FaceForm[Darker[Gray]],
Rectangle[{0, 0}, {80, 63},
RoundingRadius -> 4],(*code for picture*){rec[{80, 0}, {160, 63},
pic], FaceForm[Opacity[0]],
Rectangle[{80, 0}, {160, 63},
Inset[Pane[
Style[txt1, 12, TextAlignment -> Left], {Scaled[1],
Scaled[0.75]}, Alignment -> Center,
ImageSizeAction -> "Scrollable"], {0, 8}, {Left, Bottom}, {78,67}],
Flatten[Transpose[{Flatten[(Table[
RandomChoice[{GrayLevel[0.15], c0[[#1]]}], {3}] &) /@
Range[2, 4, 1]],
Function[{Xs, Ys},
Rectangle[{Xs, Ys}, {Xs + 16, Ys + 9},
RoundingRadius -> 4]], {Flatten[Table[Range[0, 32, 16], {3}]],
Flatten[(Table[#1, {3}] &) /@ Range[63, 81, 9]]}]}]](*,{Black,
Thickness[0.005],Line[{{0,63},{159,63}}]}*)},
PlotRange -> {{0, 160}, {0, 90}}, Method -> {"ShrinkWrap" -> True},
ImagePadding -> 2, ImageMargins -> 0, ImageSize -> 500]


produces:

You need further refinements to clean up. In particular, the image needs to be masked with a rectangle with rounded corners.

EDIT: For masking an image with a round-cornered reactangle, play with the parameters of Rectangle in

 pic2 = ImageAdd[ pic,
Graphics[{Black, Rectangle[{2, 1}, {4, 2}, RoundingRadius -> .2]}]]


Update: For better masking using SetAlphaChannel and better handling of image size (Thanks: @ssch and @Jens)

roundImage[img_, r_] := Module[{dim = ImageDimensions[img], sr},
sr = Max[dim]*r;
SetAlphaChannel[img,
Graphics[{White, Rectangle[Scaled[{0, 0}], Scaled[{1, 1}], RoundingRadius -> sr]},
Background -> Black, PlotRangePadding -> 0,
PlotRange -> {{0, 0}, dim}\[Transpose], AspectRatio -> Automatic] ]]

• In case you want to layer these rectangles on top of other graphics, it may be a slight improvement to change the masking procedure to an actual alpha mask by doing something like this: pic2 = SetAlphaChannel[pic, Graphics[{White, Rectangle[{2, 1}, {4, 2}, RoundingRadius -> .2]}, Background -> Black, PlotRangePadding -> None]] (you'll see the difference only if you display the result with a background.

• I made a function to automate the handling of image size: roundImage[img_, r_] := Module[{dim = ImageDimensions[img], sr}, sr = Max[dim]*r; SetAlphaChannel[img, Graphics[{White, Rectangle[Scaled[{0, 0}], Scaled[{1, 1}], RoundingRadius -> sr]}, Background -> Black, PlotRangePadding -> 0, PlotRange -> {{0, 0}, dim}\[Transpose], AspectRatio -> Automatic] ]]

• @ssch and Jens,thank you both. Will update with your suggestions.

You can also use Framed to frame e.g. Text elements in your graphics, which also takes the RoundingRadius option. The size of the resulting rounded frame is depending on the text (or other) element.

A quick´n dirty version of your theme could be:

Framed[Row[{Framed[Style[Text[" \$ "], 40, Bold, Magenta],

or within a Graphics context:
Graphics[Text[
