I am a Dek

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.

White becomes black, yellow becomes blue, etc. This is assigned to the image window and is typically displayed in the window title bar. Raw images are expected to have one byte per pixel unless ImageMagick is compiled in the default bit mode or in bit mode. The default is 14 point Courier.


A label is not atnialias on the image, but is embedded in the image datastream via a Label tag or similar mechanism. Use text to annotate an image with text. The pixels are processed one at a time, but a imagemaglck pixel of a image can be specified with anntialias pixel index represented by p.

Use image to composite an image with another image. Blur with the given radius, standard deviation sigmaand angle. The color of an opaque pixel is fully visible while the color of a transparent pixel color is entirely absent pixel color is ignored.

The default quality is This option lists information about the ImageMagick configuration. To extract a profile, the —profile option is not used. 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 specifies the distance upward from the bottom edge of the image to the bottom row to remove.

The color of the border is specified with the —mattecolor command line option. To specify the amount to be removed, use —shave instead. For example Center gravity forces the text imagemqgick be centered within the image. Resource limits may also be set using environment variables.


Similarly, using -type TrueColorMatte will force the encoder to write an alpha channel even though the image is opaque, if the output format supports transparency. Transformations are cumulative within the —draw option.

The red, green, and blue intensities of an image are negated. However, some formats e. In no event shall ImageMagick Studio be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise, arising from, out of or in connection with ImageMagick or the use or other dealings in ImageMagick.

Paeth 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. It specifies an X window by id, nameor root. The value for File is in number of files and the values for the other resources are in Megabytes. If the -deconstruct option appears after all of the input images, all images are deconstructed. Follow the text coordinates with a string. If only a single 0 is provided, auto-thresholding will be performed.

An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis. Presently only square kernels are supported.

I’m guessing by your screenshots that you’re using this on Mac OS X. The —gravity option is also used in concert with the —geometry option imagemaigck other options that take geometry as a parameter, such as the —crop option. Follow the pixel coordinate with a method see the color primitive for a description of methods.

If the XML library is not present, the option is ignored.

Normally, this integer value is zero or one. The right side is saved as the green channel.


You can also use the following special formatting syntax to print Exif information contained in the file:. This option specifies the sampling factors to be used by the JPEG encoder for chroma downsampling. However, if the image delay is 40 or 50, the delay it is changed to The comment is not drawn on the image, but is embedded in the image datastream via a “Comment” tag or similar mechanism. To increase the size of an image, use a value greater than e.


ImageMagick: ImageMagick – Image Processing and Display Package

The degree of lightening or darkening is proportional to the difference between the source color and 0. Use color to change the color of a pixel to the fill color see —fill. Antialiax principal function of noise peak elimination filter is to smooth the objects within an image without losing edge information and without creating undesired structures. Gamma is an exponent that ranges from 0. The —channel setting can be used to specify the output channel of the result.

Anrialias option is most useful for extracting a subregion of a very large raw image. The width and height give the size of the image that omagemagick after cropping, and x and y are offsets that give the location of the top left corner of the cropped image with respect to the original image. The transmogrified image overwrites the original image.

However, if the image is x or x, it is resized to x Specify the width of the region to be removed from both sides of the image and the height of the regions to be removed from top and bottom. This is the case when matte is full coverage for pixels inside the shape, zero outside, and between zero and on the boundary.

If all three color antlalias are the same, the result is a bi-level image.
