Actually i use the last version of Xara and i have one problem

If i create for example one imagen with some elements for create one banner , when i export this image , each image i create for this banner by separate for before create the banner , each image has different size , and i donīt understand , for example with other programs i create for example one square and insert into the imagen i want put and only export the size of square , but with this program if one image some pixel out of square my image more big

There are some method for only export this square with the images into of it and no export the other and in this way see the same size ?


Thankīs regards
