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.

[Resolved] Anti-alias image help. – ImageMagick
The value for File is in number of files. The sequence of images is terminated by the appearance of any option. This is the case when matte is full coverage for pixels inside the shape, zero outside, and between zero and on the boundary.
The direction you choose specifies where to position the text when annotating the image. By default the image is tiled onto the background of the target window.
transparency – How do I avoid this ImageMagick anti-aliasing discoloration? – Stack Overflow
Follow the pixel coordinate with a method see the color primitive for a description of methods. The default gravity for the —page option is NorthWesti.
When used with the identify utility, use this option imayemagick print information about the image in a format of your choosing.
It may be used to adjust the rendered size for desktop publishing purposes by adjusting the scale applied to the pixels. If disk has a hard limit, the program will fail.
Options are processed in command line order. The default is the compression type of the specified image file. For example, to define a circle centered atthat extends touse: For reasonable results, radius should be larger imagemmagick sigma. The image read from the file is used as a clipping mask.
If the image matte channel is disabled, then all pixels in the image are treated as opaque. Gamma less than 1. For example, suppose you want to replace the red channel of alpha. Absolute, Perceptual, Relative, Saturation The default intent is undefined.
A series of operations can be accomplished by using a matrix that is the multiple of the matrices for each operation.
Note, these two command are equivalent: For reasonable results, radius should be larger than sigma. Otherwise, the intensity gray level of each pixel is used.
This extra channel usually defines a mask which represents a sort of a cookie-cutter for the image. Screening any color with black leaves the original color unchanged. Otherwise, the intensity gray level of each pixel is used. The default quality is If this option is omitted, the JPEG library will use its own default values. When writing to a MNG file, a -page option appearing ahead of the first image in the sequence with nonzero width and height defines the width and height values that are written in the MHDR chunk.
The -frame option is not affected by the -gravity option. Rotate rotates subsequent shape primitives and text primitives about the origin of the main image. For example, to create a postscript file that will render only the black pixels of a bilevel image, use:. See —resize for details about the geometry specification. The —channel setting can be used to specify the output channel of the result. I’ve noticed particularly at lower densities eg. This option creates a single image where the images in the original set are stacked top-to-bottom.
Use text to annotate an image with text. Otherwise, this option is ignored. CopyGreen The resulting image is the green layer in image replaced with the green layer in composite image. With this option, composite image is used as a displacement map.
