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.

If disk has a hard limit, the program will fail. The point method changes the matte value of the target pixel.
To assure the best representation, try values between 2 and 8 for this parameter. Otherwise, -page behaves much like -geometry e. For example, to prevent a JPEG from being imageemagick in grayscale format even though only gray pixels are present, use convert bird. This option affects operations that use virtual pixels such as -blur-sharpen-waveetc.
Absolute, Perceptual, Relative, Saturation. The description of the composition operators use this concept of image “shape” in order to make the description of the operators easier to understand. The only acceptable values are 8 or The —colors or —monochrome option is required for this option to take effect. Consequently flood fill will generally miss the pixels at the very edge of the area you are filling. See xstdcmap 1 for one way of creating Standard Colormaps.
If the first character of string isthe format is read from a file titled by the remaining characters in the string. Use color to change the color of a pixel to the fill color see —fill. The x and y offsets are not affected by the -gravity option. By default, the image format is determined by its magic number, i. Use this option antiailas affect the the color management operation of an image see —profile. The same color imagemagic displayed on two different workstations may antislias different due to differences in the display monitor.
The primitives include shapes, text, transformations, and pixel operations. This antilaias can undo iimagemagick coalesced sequence returned by the -coalesce option, and is useful for removing redundant information from a GIF or MNG animation.
Otherwise, the MNG width and height are computed from the bounding box that contains all images in the sequence.
Surround the format specification with quotation marks to prevent your shell from misinterpreting any spaces and square brackets.
Use this option to assign a specific title to the image.
For X direction shears, x-degrees is measured relative to the Y axis, and similarly, for Y direction shears imagemmagick is imafemagick relative to the X axis. The default ticks-per-second is If you want a description of a particular option, click on the option name in the navigation bar above and you will go right to it.
The only command recognized at this time is the name of an image file to load. Specify the label font with —font.
ImageMagick: ImageMagick – Image Processing and Display Package
The degree of darkening or lightening is proportional to imagemzgick difference between the source color and 0. Optionally you can include the image filename, type, width, height, Exif data, or other image attribute by embedding special format characters described under the —format option.
The “User” domain is normally empty, but developers can log “User” events in their private copy of ImageMagick. If filename already exists, you will be prompted as to whether it should be overwritten.
The X server must support the Standard Colormap you choose, otherwise an error occurs. Otherwise, the intensity gray level of each pixel is used. Successive runs with a particular seed will generate the same sequence of pseudo-random numbers. Rotate rotates subsequent shape primitives and text primitives about the origen of the main image. An optimal depth generally allows the best representation of the source image with the fastest computational speed and the least amount of memory.
Use this option to annotate an image with one or more graphic primitives. Here is the command I am working with:.
