"What resizing and other options are available?"
The addtional options for each view are performed in the order show on this page:
- Grayscale: ;grayscale
Convert from full color to grayscale.
- Rotate: name=rotate value=90 or name=rotate value=180 or name=rotate value=270
Rotates the image clockwise 90, 180, or 270 degrees.
- Flip: name=flip value=tb or name=flip value=lr
Flip the image top to bottom, or left to right.
- Crop: name=cr_t value=10 or name=cr_b value=20 or name=cr_r value=30 or name=cr_l value=40
Crop pixels off the top, bottom, left, and right of the image.
- Absolute Resize: name=width value=100 or name=height value=100
Resize to an exact pixel size. If only height or width is specified, the resize is done proportionally.
- Differential Resize: name=width value=a100 or name=height value=s100
Resize by adding (a prefix) or subtracting (s prefix) a number of pixels.
- Percentage Resize: name=width value=200p or name=height value=25p
Resize by percentage of the original size.
- Differential Percentage Resize: name=width value=a200p or name=height value=s25p
Resize by adding or substracting a percentage of the original size.
- Minimum and Maximum Resize: name=width value=min200 or name=height value=max400
Resize to a specified limit if the image is outside the limit. Note that minimum is applied first.
- Complex Resize: name=width value=a50pmin200max400
You can combine the resize options in the order "change," "minimum," "maximum." This instruction says: Add 50 percent to the existing width, making sure the image is at least 200 pixels wide but not more than 400 pixels wide, and since the height is not specified make sure it is resized proportionally.
- Matte Resize: name=matte value=50
A reduction is done, centering the image and filling in the edges to create an image with a "matte" around it. A percentage of the image size between 1 and 100 can be specified.
- Resize Focus: name=focus value=1 or name=focus value=5
Override automatic sharpness/smoothing control. 1 is very smooth, 5 is very sharp.
- Frame Width and Height: name=fwidth value=320 or name=fheight value=200
After all that resizing, you may still want to crop or pad the image to fit an exact size on the page. This will ensure the final image is an exact size for the screen. If cropping is required, the center of the image is kept. Padding is distributed equally to all sides.
- Adjust White: name=ca_ws value=255 or name=ca_ws value=-255
Specify the amount to brighten or darken the image.
- Adjust Red: name=ca_rs value=255 or name=ca_rs value=-255
Specify the amount to brighten or darken the red color channel.
- Adjust Green: name=ca_gs value=255 or name=ca_gs value=-255
Specify the amount to brighten or darken the green color channel.
- Adjust Blue: name=ca_bs value=255 or name=ca_bs value=-255
Specify the amount to brighten or darken the blue color channel.
- Swap Colors: Exchanges the color channels.
- name=ca_sc value=rg Swap red and green.
- name=ca_sc value=gb Swap green and blue.
- name=ca_sc value=br Swap blue and red.
- Reverse Colors: Creates a negative image where bright areas are made dark, and dark areas are made light.
- name=ca_rw value=on Reverse red, green, and blue.
- name=ca_rr value=on Reverse red.
- name=ca_rb value=on Reverse green.
- name=ca_rg value=on Reverse blue.
