Position buttons
These buttons allow you to choose where on the screen the image will be positioned. The arrow buttons align the image at the edges and corners of the screen, the round button in the middle centres the image in the middle of the screen, and the “Random” button picks a new random position for the image each time the image changes.
Auto-rotate images
Some cameras automatically save a value to the EXIF metadata that is part of the image file to say which way up the camera was being held when the photograph was taken. Enabling the “Auto-rotate images” option makes JPEG Saver check for this information and autmatically rotate the image to be the right way around.
Greyscale images
This option makes JPEG Saver display foreground images and videos in greyscale. The backgrounds, text and other items are not affected, except for image copy backgrounds where the copy of the image is made after it has been converted to greyscale.
Display mode / Multi-monitor button
If you have more than one monitor configured then this area displays a button saying “Multi-monitor…” which takes you to the multi-monitor options dialog. Otherwise it displays a drop-down box containing a list of display modes.
This option allows you to choose a different display resolution for JPEG Saver to use. The list of options is generated by asking the graphics card which modes are available - though these are the modes supported by the card and might not be supported by your monitor!
If you do choose a different display mode, JPEG Saver will be slightly slower to start up and exit but could perform a bit better during transitions. This is because in “No change“ mode it uses a window that covers the whole screen instead of using DirectX “exclusive mode”.
Resizing options
The image on this page shows advanced resizing mode. Simple resizing mode has just the two options for fit and method, with both larger and smaller images being resized to 100% of the display size.
To switch between the modes, right-click the dialog and choose the other mode from the popup context menu.
Resize large images
Setting this option means that images larger than the specified size are to be scaled down to fit. The small button at the end toggles between scaling to a percentage of the screen size, or a fixed size in pixels.
Resize large fit
Sets the method for fitting the image to the screen. The options are:
- Width and height — the image is scaled so that both the width and height fit the target size.
- Width — the image is scaled so that the width fits the target size. Tall images could overflow at the top or bottom or both.
- Height — the image is scaled so that the height fits the target size. Wide images could overflow at the left or right or both.
- Fill — the image is scaled to completely fill the target size. Unless the image is the right shape it will overflow the target area.
- Stretch — the image is scaled to git the target size without maintaining its original shape.
Resize large method
Sets the scaling method or antialiasing filter to use when resizing larger images.
Resize small images
Setting this option scales images smaller than the specified size up.
Resize small fit
Sets the method for fitting the image to the screen.
Resize small method
Sets the scaling method or antialiasing filter to use when resizing smaller images.
