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.

Anyway, this method is mainly for imagemagivk elements that can be rasterized at a higher density and then get downsized and the downsizing does some sort of antialiasing.
This option produces a solarization effect seen when exposing a photographic film to light during the development process. Darkens the destination color to reflect the source color.
This option applies a special anrialias to the image, similar to the effect achieved in a photo darkroom by sepia toning. Consequently this has no effect on the image sequence order.
To read the XC format, follow the colon with a color specification. This option creates a single image imagemahick the images in the original set are stacked top-to-bottom.
The —page option can be used to establish the dimensions of the mosaic and to locate the images within the mosaic. A number of algorithms search for a target color.
Difference The result of abs composite image – image. Otherwise, this option is ignored.
imagemagikc The —colors or —monochrome option, or saving to a file format which requires color reduction, is required for this option to take effect. Otherwise, this option is ignored. Presently only square kernels are supported. Point requires a single coordinate. By default, a shared colormap is allocated. Essentially flood fill, or even color replace, does not understand anti-aliasing, nor does it use anti-aliasing techniques itself. If filter-type is 5, adaptive filtering is used when quality is greater than 50 and the image does not have a color map, otherwise no filtering is used.
None of the image data of image will be in the result.

Separate indexes with a comma omagemagick. If this profile is not stripped from the image, then Photoshop will continue to treat the image using its former resolution, ignoring the image resolution specified in the standard file header.
Subtract The result of composite image – imagewith underflow wrapping around mod By default the file is written to its original name. Specify the label font with —font.
Here the matte information is ignored. Coordinates are integers separated by an optional comma.
Threshold ranges from 0 to QuantumRange and is a measure of the extent of the sepia toning. If the —deconstruct option appears after all of the input images, all images are deconstructed. Each image pixel may also optionally if the image matte channel is enabled have an associated level of opacity ranging from opaque to transparentwhich may be used to determine the influence of the pixel color when compositing the pixel with another image antilias.
Empty triangles left over from rotating the image are filled with the color defined as background class backgroundColor.

For example, -limit memory 32 -limit map 64 limits memory When the pixel cache reaches the memory limit it uses memory mapping. The actual number of colors in the image may be antiwlias than your request, but never more. This option affects operations that use virtual pixels such as —blur—sharpen—waveetc.
