Scaling of Images

Generate a thumbnail of the image as required, or make a specific scaling.

Parameters:

Actions mode Instruction meaning Parameter format Parameter description Result description
Scale in with fixed aspect ratio Scale s/w/h W resultant width after scaling
H resultant height after scaling
value range[1,9999]
The scaled image is not larger than the assigned width and height, and is the maximum inscribed rectangle of w x h
Scale out with fixed aspect ratio Scale outside so/w/h W resultant width after scaling
H resultant height after scaling
value range[1,9999]
The scaled image is not smaller than the assigned width and height, and is the minimum circumscribed rectangle of w x h
Scale with fixed aspect ratio and assigned height Scale height sh/h H resultant height after scaling
value range[1,9999]
Resultant height after assigned scaling, the width is self-adapted
Scale with fixed aspect ratio and assigned width Scale width sw/w W resultant width after scaling
value range[1,9999]
Resultant width after assigned scaling, the height is self-adapted
Scale in proportion with fixed aspect ratio Scale percent sp/n N 0.X% of the resultant side length after scaling of that of the original image
value range[1,1000]
0.X% of the resultant width and height after assigned scaling are of that of the original image
Scale without fixed aspect ratio Scale force sf/w/h W resultant width after scaling
value range[1,9999]
Resultant width and height after assigned scaling
Scale as per pixel count within the area with fixed aspect ratio Scale area sa/n N resultant total pixel count after scaling
value range[1,100000000]
Resultant total pixel count after assigned scaling, w x h=n, there may be the error of 1 pixel in the result
Scale with fixed aspect ratio and added white border Scale border sb/w/h W resultant width after scaling
H resultant height after scaling
value range[1,9999]
The scaled image is not larger than the assigned width and height, and is the maximum inscribed rectangle of w x h; the scaled image scope is not be larger than assigned width and height, the filling background of the non-image part within assigned width and height scope is white
Scale with fixed aspect ratio and added color border Scale border sb/w/h/str W resultant width after scaling
H resultant height after scaling
value range[1,9999]
Str background filling color, starting with_
value range[000000,FFFFFF]
The scaled image is not larger than the assigned width and height, and is the maximum inscribed rectangle of w x h; the scaled image scope is not be larger than assigned width and height, the filling background of the non-image part within assigned width and height scope is the Str assigned color, corresponding to RRGGBB (supporting RGB as well)
Scale with fixed aspect ratio and assigned height, and white border added to width Scale height border shb/w/h W resultant width after scaling
H resultant height after scaling
value range[1,9999]
The assigned height and width are self-adapted, the scaled image is equal to the assigned height and width; if the self-adapted width is not consistent with the assigned height, the filling background is white
Scale with fixed aspect ratio and assigned width, and white border added to height Scale width border swb/w/h W resultant width after scaling
H resultant height after scaling
value range[1,9999]
The assigned width and height are self-adapted, the scaled image is equal to the assigned width and height; if the self-adapted height is not consistent with the assigned height, the filling background is white
Scale with fixed aspect ratio and assigned height, and color border added to width Scale height border shb/w/h/str W resultant width after scaling
H resultant height after scaling
value range[1,9999]
Str background filling color, starting with_
value range[000000,FFFFFF]
The assigned height and width are self-adapted, the scaled image is equal to the assigned width and height; if the self-adapted width is not consistent with the assigned width, the filling background is the Str assigned color, corresponding to RRGGBB (supporting RGB as well)
Scale with fixed aspect ratio and assigned height, and color border added to width Scale width border swb/w/h/str W resultant width after scaling
H resultant height after scaling
value range[1,9999]
Str background filling color, starting with_
value range[000000,FFFFFF]
The assigned width and height are self-adapted, the scaled image is equal to the assigned width and height; if the self-adapted height is not consistent with the assigned height, the filling background is the Str assigned color, corresponding to RRGGBB (supporting RGB as well)

Example: Scale the image with fixed aspect ratio; the width and height after scaling is not larger than 200 x 300
