Picture Settings
Select Format
This button selects the picture format for the converted pictures. This selection must be made in order to start batch processing.
Determine quality
This button, which is activated when the format JPEG is selected, selects the compression-ratio of the image files. In addition to four predefined quality levels, there is also an option to specify the quality manually as a percentage. Selecting the manual setting releases the quality slider, which can be used to set the desired compression rate. Basically, the lower the quality is chosen, the smaller the required disk-space for the file, but the image quality also decreases with decreasing ratio.
Note: This selection must be made to start batch processing for JPG images.
Size calculation
The "Image size to" popup-button can be used to set how to calculate the dimensions of the image files. If no selection is made, the dimensions of the image file remain. For the recalculation of the dimensions the appropriate fields for the X-value (width) and the Y-value (height) can be set. The following options for recalculation of the image dimensions are available:
- Shrink to fit
- All files whose image dimensions larger are recalculated and scaled according to the given values. Images whose image dimensions are smaller than the specified specifications remain unaffected by the recalculation.
- Enlarge to fit
- All files whose image dimensions are smaller are recalculated and enlarged according to the given values. Images whose image dimensions are larger than the specified specifications remain unaffected by the recalculation.
- Shrink or enlarge to fit
- This option is a combination of the two previous options. Pictures that are larger than the specified specifications, are reduced in size, images that are smaller than the specified specifications are enlarged.
- Shrink to exact
- This option causes the target image to shrink to exactly the specified values, regardless of the original aspect ratio. Images that are smaller than the specified specifications remain untouched.
- Enlarge to exact
- This option causes the target image to be enlarged to the specified values, regardless of the original aspect ratio. Images that are larger than the specified specifications remain untouched.
- Shrink or enlarge to exact
- This option is a combination of the two previous options. All images are adjusted to the specified specifications, regardless of the original aspect ratio.
- Resize to fit height
- This option will recalculate the image to the desired height. The width is adjusted in proportion to the height. Thus, all processed images have the same height.
- Resize to fit width
- This option will recalculate the image to the desired width. The height is adjusted proportionally to the width. Thus, all processed images have the same width.
- Crop to fit
- This option crops the images to match the specifications. This option also provides an option for setting the fill color for any blank space that may appear. To do this, the color selector must be pressed and the desired color selected. In addition, it is possible to define a starting position for the cutting operation in order to be able to define more precisely which area of an image is to be cut out.
- Crop to height
- This option crops the image to the desired height. The width, however, remains untouched.
- Crop to width
- This option crops the image to the desired width. The height, however, remains untouched.
- Resize to height / crop / pad with color
- This option first recalculates the image to be processed to a desired height, then crops the image to the desired width. If the original width is smaller than the output format, the "empty" area will be filled with color
- Resize to width / crop / pad with color
- This option first recalculates the image to be processed to a desired width, then crops the image to the desired height. If the original height is smaller than the output format, the "empty" area will be filled with color
- Proportional resizing
- This option increments / decrements the image by the specified values. It should be noted that for this option both the width (x-value) and the height (y-value) must be specified.
- Change resolution (DPI)
- This option recalculates the DPI resolution of the images. Thus, images, e.g. with a DPI resolution of 300dpi can be converted to 72dpi. The x and y pixel dimensions are unaffected by this conversion.
Note: When resizing pictures from the formats PSD or PNG, any transparency and layers are lost.
Define image dimensions
The X-value (width) and Y-value (height) fields can be used to specify the dimensions that the images should have after processing. It is not absolutely necessary to provide both fields with values. If a field is left blank, the original value of the image will be used for the empty X or Y value.
