Enlarging images

[chrisj]

I have two images that I didn't create, but need to be re-sized. A wide gradient bar with rounded-corners and a box with rounded corners (attached). I suspect I may need to recreate these in GIMP (unless there's another way). Can you help me re-create them or provide some other guidance? Thanks

Yes, redoing them is best.

The wide gradient is easy:

• load original image, and with the Color picker ( ) set the foreground color to the darkest gray and the background to the lightest.
• "File/New", give it the outer size you require, and in the advanced option, fill with transparency.
• Select/All
• Select/Rounded rectangle, adjust size of corners
• Bucket-fill () with foreground color, and "fill whole selection"
• "Select/Shrink" and shrink by the width of the gray border
• Start the Blend () tool. Click on the gradient and choose the Foreground-to-Background one
• Apply gradient: click on bottom of selection, start dragging, depress the Control key (this insures your gradient is perfectly upright), continue dragging to top of selection, and release mouse, then Control.
• Save as PNG
  

The "box" is more complex to redo, but a blunt resize wouldn't give good results. But the real question is why is done that way:

• what are the tiny transparent dots in the corners supposed to be?
• why are the corners slightly larger?
• why is there a non-transparent outline on right and bottom?
• (and why is it a GIF when the other one is a PNG).

Thanks for your informative reply. Greatly appreciated.
The "box" is simply a conatiner with a thin grey border, rounded corners, white background.
I didn't create it, so I don't know the answers to your questions. Any help re-creating a lengthened image similar to it, will be appreciated. Thanks.

Then you can do it like the other one, but replace the gradient with a mere bucket-fill with white.
