Macro: with-transformation ((&key x1 x2 width y1 y2 height reverse-x reverse-y radians image) &body body)

Executes BODY such that all points and width/height data are subject to a simple affine transformation defined by the keyword parameters. The new x-axis of IMAGE will start at X1 and end at X2 and have length WIDTH. The new y-axis of IMAGE will start at Y1 and end at Y2 and have length HEIGHT. In both cases it suffices to provide two of the three values - if you provide all three they have to match. If REVERSE-X is false the x-axis will be oriented as usual in Cartesian coordinates, otherwise its direction will be reversed. The same applies to REVERSE-Y, of course. If RADIANS is true angles inside of BODY will be assumed to be provided in radians, otherwise in degrees.

5.1.4 Ordinary functions

Function: allocate-color (red green blue &key alpha errorp image)

Finds the first available color index in the image IMAGE specified, sets its RGB values to those requested (255 is the maximum for each), and returns the index of the new color table entry, or an RGBA value in the case of a true color image. In either case you can then use the returned value as a COLOR parameter to drawing functions. When creating a new palette-based image, the first time you invoke this function you are setting the background color for that image. If ALPHA (not greater than 127) is provided, an RGBA color will always be allocated. If all +GD-MAX-COLORS+ have already been allocated this function will, depending on the value of ERRORP, either raise an error or return NIL.

Package

cl-gd.

Source

colors.lisp.

Function: alpha-blending-p (&optional image)

Returns whether pixels drawn on IMAGE will be copied literally including alpha channel information (return value is false) or if their alpha channel information will determine how much of the underlying color will shine through (return value is true). This is only meaningful for true color images.

Package

cl-gd.

Source

colors.lisp.

Function: (setf alpha-blending-p) (&optional image)

Determines whether pixels drawn on IMAGE will be copied literally including alpha channel information (if BLENDING is false) or if their alpha channel information will determine how much of the underlying color will shine through (if BLENDING is true). This is only meaningful for true color images.

Function: color-components (color &key image)

Returns a list of the color components of COLOR. The components are in the order red, green, blue, alpha.

Package

Source

colors.lisp.

Function: copy-image (source destination source-x source-y dest-x dest-y width height &key resample rotate angle resize dest-width dest-height merge merge-gray)

Copies (a part of) image SOURCE into image DESTINATION. Copies the rectangle with the upper left corner (SOURCE-X,SOURCE-Y) and size WIDTH x HEIGHT to the rectangle with the upper left corner (DEST-X,DEST-Y).

If RESAMPLE is true pixel colors will be smoothly interpolated. If RESIZE is true the copied rectangle will be strechted or shrinked so that its size is DEST-WIDTH x DEST-HEIGHT. If ROTATE is true the image will be rotated by ANGLE. In this particular case DEST-X and DEST-Y specify the CENTER of the copied image rather than its upper left corner! If MERGE is true it has to be an integer in the range 0-100 and the two images will be ’merged’ by the amount specified. If MERGE is 100 then the source image will simply be copied. If instead MERGE-GRAY is true the hue of the source image is preserved by converting the destination area to gray pixels before merging.

The keyword options RESAMPLE, ROTATE, RESIZE, MERGE, and MERGE-GRAY are mutually exclusive (with the exception of RESAMPLE and RESIZE). ANGLE is assumed to be specified in degrees if it’s an integer, and in radians otherwise.

Function: draw-arc (center-x center-y width height start end &key straight-line center-connect filled color image)

Draws a partial ellipse centered at (CENTER-X, CENTER-Y) with width WIDTH and height HEIGHT. The arc begins at angle START and ends at angle END. If STRAIGHT-LINE is true the start and end points are just connected with a straight line. If CENTER-CONNECT is true, they are connected to the center (which is useful to create ’pie slices’). If FILLED is true the arc will be filled with COLOR, otherwise it will be outlined.

Function: draw-freetype-string (x y string &key anti-aliased point-size angle convert-chars line-spacing font-name do-not-draw color image)

Draws the string STRING in color COLOR at position (X,Y) using the FreeType library. FONT-NAME is the full path (a pathname or a string) to a TrueType font file, or a font face name if the GDFONTPATH environment variable or FreeType’s DEFAULT_FONTPATH variable have been set intelligently. The string may be arbitrarily scaled (POINT-SIZE) and rotated (ANGLE in radians). The direction of rotation is counter-clockwise, with 0 radians (0 degrees) at 3 o’clock and PI/2 radians (90 degrees) at 12 o’clock. Note that the ANGLE argument is purposefully _not_ affected by WITH-TRANSFORMATION. If ANTI-ALIASED if false, anti-aliasing is disabled. It is enabled by default. To output multiline text with a specific line spacing, provide a value for LINE-SPACING, expressed as a multiple of the font height. The default is to use 1.05. The string may contain XML character entity references like "À". If CONVERT-CHARS is true (which is the default) characters of STRING with CHAR-CODE greater than 127 are converted accordingly. This of course pre-supposes that your Lisp’s CHAR-CODE function returns ISO/IEC 10646 (Unicode) character codes.

The return value is an array containing 8 elements representing the 4 corner coordinates (lower left, lower right, upper right, upper left) of the bounding rectangle around the string that was drawn. The points are relative to the text regardless of the angle, so "upper left" means in the top left-hand corner seeing the text horizontally. Set DO-NOT-DRAW to true to get the bounding rectangle without rendering. This is a relatively cheap operation if followed by a rendering of the same string, because of the caching of the partial rendering during bounding rectangle calculation.

Function: fill-image (x y &key border color image)

Floods a portion of the image IMAGE with the color COLOR beginning at point (X, Y) and extending into the surrounding region.

drawing.lisp.

Function: find-color (red green blue &key alpha exact hwb resolve image)

Tries to find and/or allocate a color from IMAGE’s color
palette. If EXACT is true, the color will only be returned if it is already allocated. If EXACT is NIL, a color which is ’close’ to the color specified by RED, GREEN, and BLUE (and probably ALPHA) might be returned (unless there aren’t any colors allocated in the image yet). If HWB is true, the ’closeness’ will be determined by hue, whiteness, and blackness, otherwise by the Euclidian distance of the RGB values. If RESOLVE is true a color (probably a new one) will always be returned, otherwise the result of this function might be NIL. If ALPHA (not greater than 127) is provided, an RGBA color (or NIL) will be returned.

ALPHA, EXACT, and HWB are mutually exclusive. RESOLVE can’t be used together with EXACT or HWB.

Function: true-color-to-palette (&key dither colors-wanted image)

Converts the true color image IMAGE to a palette-based image using a high-quality two-pass quantization routine. If DITHER is true, the image will be dithered to approximate colors better, at the expense of some obvious "speckling." COLORS-WANTED can be any positive integer up to 256 (which is the default). If the original source image includes photographic information or anything that came out of a JPEG, 256 is strongly recommended. 100% transparency of a single transparent color in the original true color image will be preserved. There is no other support for preservation of alpha channel or transparency in the destination image.

If STREAM is a character stream, the user of this function has to make sure the external format yields faithful output of all 8-bit characters. WBMP file support is black and white only. The color index specified by the FOREGOUND argument is the "foreground," and only pixels of this color will be set in the WBMP file

Package

cl-gd.

Source

colors-aux.lisp.

Macro: with-rebinding (bindings &body body)

REBINDING ( { var | (var prefix) }* ) form*

Evaluates a series of forms in the lexical environment that is formed by adding the binding of each VAR to a fresh, uninterned symbol, and the binding of that fresh, uninterned symbol to VAR’s original value, i.e., its value in the current lexical environment.

The uninterned symbol is created as if by a call to GENSYM with the string denoted by PREFIX - or, if PREFIX is not supplied, the string denoted by VAR - as argument.

The forms are evaluated in order, and the values of all but the last are discarded (that is, the body is an implicit PROGN).

Macro: with-unique-names ((&rest bindings) &body body)

Syntax: WITH-UNIQUE-NAMES ( { var | (var x) }* ) declaration* form*

Executes a series of forms with each VAR bound to a fresh, uninterned symbol. The uninterned symbol is as if returned by a call to GENSYM with the string denoted by X - or, if X is not supplied, the string denoted by VAR - as argument.

The variable bindings created are lexical unless special declarations are specified. The scopes of the name bindings and declarations do not include the Xs.

The forms are evaluated in order, and the values of all but the last are discarded (that is, the body is an implicit PROGN).
