to convert PDF into Images. This works good for teh most files. But there is a problem with antialias (i think). When i zoom in the output image i. Well I’m trying to make the image’s edges soften so they don’t look sharp ( transparent background), and I can’t seem to get it to work. Have you tried setting -background Red -alpha Background? I suspect that the background color is defaulting to black, which is then being blurred with the red.

Refer to -visual for more details.
Brightens the destination color to reflect the source color. Choose from these previews:.
Similarly, the y offset normally specifies the topmost row to remove, but if the -gravity option is present with SouthWest, South, or SouthEast gravity, it antualias the distance upward from the bottom edge of the image to the bottom row to remove.
This option takes last image in the current image sequence and inserts it at the given index.
Choose from these intents: The ordering of an existing color palette may be altered. Note this offset and the image size. For example, if you want to anntialias quality 75 for the main image and quality 90 to compress the opacity data, use —quality However, if the filename extension matches a supported format, the extension is replaced with the image format type specified with —format.
The replace method changes the matte value of any pixel that matches the color of the antialoas pixel.
The order of the kernel is determined by the square root of the number of entries. The —gravity option is also used in concert with the —geometry option and other options that take geometry as a parameter, such as the —crop option.
Each pixel is replaced by the most frequent color in a circular neighborhood whose width is specified with radius. The matte channel is ignored set tofull coverage. Otherwise, —page behaves much like —geometry e.
Anti-aliasing – ImageMagick
Use this option to affect the preview operation of an image e. By default, color reduction chooses an optimal set of colors that best represent the original image. Finally, reset recolors all pixels. These transforms include image scalingimage rotationcolor reductionand others.
When creating a montage, by default the label associated with an image is displayed with the corresponding tile in the montage. If the mask image contains an alpha channel, the opacity of each pixel is used to define the mask.
Multiplying any color with black produces black. None, Line, Plane, or Partition. The degree of darkening or lightening is proportional to the difference between the source color and 0.
If the —filter option precedes the —resize option, the image is resized with the specified filter. The actual number of colors in the image may be less than your anhialias, but never more.
Convert converts an input file using one image format to an output file with a differing image format. If the -append option appears after all of the input images, all images are appended.
You can use the option -list resource to find out the limits. Usage questions are like “How do I use ImageMagick to create drop shadows? Surround the format specification with quotation marks to prevent your shell from misinterpreting any spaces and square brackets.
If the first character of string isthe image label is read from a file titled by the remaining characters in the string. The point method recolors the target pixel. The kernel is specified as a comma-separated list of integers, ordered left-to right, starting with the top row.
Floodfill changes the matte value of any pixel that matches the color of the target pixel and is a neighbor, whereas filltoborder changes the matte value of any neighbor pixel that is not the border color —bordercolor.
