SkewX and SkewY skew them with respect to the origen of the main image or the region. If -colors is also specified, the total unique colors in the image and color reduction error values are printed. Refer to the color reduction algorithm for more details. 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 default is 72 dots per inch in the horizontal and vertical direction. ImageMagick: ImageMagick вЂ“ Image Processing and Display Package Screening any color with white produces white. The transformation primitives are rotate degrees translate dx,dy scale sx,sy skewX degrees skewY degrees The pixel operation primitives are color x0,y0 method matte x0,y0 method The shape primitives are drawn in the color specified in the preceding -stroke option.ДЇor example, to extract the matte channel of the image this is the negative to what is commonly thought of as the alpha channel mask of the imageuse.Дraw a circle, then try to fill it with a pattern You will need this information to recover the steganographic image e. This option is used in concert with -density. If the x is negative, the offset is measured leftward from the right edge of the screen to the right edge of the image being displayed. Width and height give the number of columns and rows to remove, and x and y are offsets that give the location of the leftmost column and topmost row to remove. The equivalent X resource for this option is writeFilename class WriteFilename. Offsets, if present in the geometry specification, are handled in the same manner as the -geometry option, using X11 style to handle negative offsets. Note, options -dither-colorspaceand -treedepth affect the color reduction algorithm. This backdrop covers the entire workstation screen and is useful for hiding other X window activity while viewing the image. Xor The result is the image data from both composite image and image that is outside the umagemagick region. Perform local adaptive thresholding using the specified width, height, and offset. What version are you using? The offsets specify the location of the upper left corner of the cropping region measured downward and rightward with respect to the upper left corner of the image. You can use the option -list resource to find out the limits. Specifies the name of the preferred font to use in fixed typewriter style formatted text. If a clipping path is present, it will be applied to subsequent operations. 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.Д«y default, the width and height are maximum values.

Well IвЂ™m trying to make the imageвЂ™s edges soften so they donвЂ™t look sharp ( transparent background), and I canвЂ™t seem to get it to work.

But there is a problem with antialias (i think).
