Use this section to define the image’s output settings.
Choose one of the following image formats for the converted images:
BMP 24bit (Bitmap, RGB),
BMP 32bit (Bitmap, RGB+Alpha),
PNG 32 bit (RGB+Alpha).
By default this option is disabled. Converting images without Resize enabled will result in images with their original size and the file format chosen under [Format].
If you want to resize the image, enable [Resize] You now may choose one of the settings from the drop down list on the right or enter the new values for Width and Height manually in the text fields.
This option allows to easily resize the image to any size without having to calculate the correct Width and Height to keep the image’s original aspect ratio.
To convert an image file with the size 2560x1200 px (aspect ratio is 2,133) to a file that is 1000 px wide, you have two options:
Not using [Match Size]
Enter the new values for Width and Height manually into the text fields: Width = 1000px, Height = 469 px. This assumes that you know (or calculate) the Height to keep the correct Aspect Ratio.
Using [Match Size]:
If you don’t want to calculate the value for the according Height, just enter the Width value (=1000) and then enable the [Match Size] option. Now press [Convert]. The new image size is displayed next to [Match Size]: 1000x469 px.
This option allows to replace transparent image parts with a background colour. Enable the option and click on the small box next to [BG] to choose the background colour.
The coolux oo-logo contains transparent parts. Converted with [BG] disabled: the transparent parts will be kept.
The same logo is converted with [BG]-option enabled, a white BG colour is chosen: the former transparent parts on the logo are replaced by white.
This option allows to resize an image to a size with a different aspect ratio without stretching the content.
The logo (size 1024x410 px) is resized to 800x800 px. The result is a stretched image.
The logo (size 1024x410 px) is resized to 800x800 px, but this time the [Output Fit]-option is checked. The logo keeps its aspect ratio, only the canvas size’s aspect ratio changed. The canvas area that is added on top and bottom to fit to the output will appear transparent if [BG] is not checked. With [BG] checked it shows the chosen background colour.
Choose between several filtering and quality options for the scaling.
