Matplot properties
description of the Matplot entities properties
Description
The Matplot
entity is a leaf of the graphics entities hierarchy. It
represents 2D plots of surface using colors and images (see
Matplot
and Matplot1
).
 parent:
this property contains the handle of the parent. The parent of the
Matplot
entity should be of the type"Axes"
. children:
this property contains a vector with the
children
of the handle. However,Matplot
handles currently do not have anychildren
. visible:
this field contains the
visible
property value for the entity. It should be"on"
or"off"
. By default, the plot is visible, the property's value is"on"
. If"off"
the plot is not drawn on the screen. data:
this field defines a [
m
xn
]color
data matrix (double, (u)int8, (u)int16, (u)int32) or hypermatrix. The colors are interpreted according to the image_type property. The color associated tocolor(i,j)
is used do draw a small square of length 1 with center at location(x=j,y=(mi+1))
. rect:
this field contains a rowvector defined by
[xmin, ymin, xmax, ymax]
. It specifies a rectangle in the current scale and the matrix is drawn inside this rectangle. image_type:
this field defines the image type. It could be one of the values: "rgb", "rgba", "gray", "index", "red", "green", "blue", "rgb332", "rgb444", "rgb555", "rgba5551", "argb".
Colors are determinated by the data type and by image_type:
When image_type is equal to index, the data are just considered as an index in the colormap.
When image_type is equal to rgb, hypermat of int8 or uint8 will give the RGB components, hypermat of doubles will give normalized RGB components (values between 0 and 1), matrices of int8 or uint8 where number of rows is a multiple of 3 will give the RGB components, matrices of int32 will give RGB colors, matrices of uint32 will give RGBA colors where the alpha channel will be set to 0xFF.
When image_type is equal to rgba, hypermat of int8 or uint8 will give the RGBA components, hypermat of doubles will give normalized RGBA components (values between 0 and 1), matrices of int8 or uint8 where number of rows is a multiple of 4 will give the RGB components, matrices of int32 will give RGBA colors, matrices of uint32 will give RGBA colors.
When image_type is equal to gray, matrices of int8 or uint8 will give Gray level color (RGB=GRAYGRAYGRAY), for other types, data will be considered as RGB ones and converted into gray colors (0.299*R+0.587*G+0.114*B).
When image_type is equal to red, matrices of int8 or uint8 will give Red level color (RGB=RED0000), for other types, data will be considered as RGB ones and converted into red colors (a mask is applied to keep the Red component).
When image_type is equal to green, matrices of int8 or uint8 will give Green level color (RGB=00GREEN00), for other types, data will be considered as RGB ones and converted into green colors (a mask is applied to keep the Green component).
When image_type is equal to blue, matrices of int8 or uint8 will give Blue level color (RGB=0000BLUE), for other types, data will be considered as RGB ones and converted into blue colors (a mask is applied to keep the Blue component).
When image_type is equal to rgb332, matrices of int8 or uint8 will give RGB colors where R component is wrote on 3 bits, G component on 3 bits and B component on 2 bits. For other data types, RGB (888) data are converted into RGB (332).
When image_type is equal to rgb444, matrices of int16 or uint16 will give RGB colors where each components is wrote on 4 bits. For other data types, RGB (888) data are converted into RGB (444).
When image_type is equal to rgb555, matrices of int16 or uint16 will give RGB colors where each components is wrote on 5 bits. For other data types, RGB (888) data are converted into RGB (555).
When image_type is equal to rgb4444, matrices of int16 or uint16 will give RGBA colors where each components is wrote on 4 bits. For other data types, RGBA (8888) data are converted into RGBA (4444).
When image_type is equal to rgb5551, matrices of int16 or uint16 will give RGBA colors where each nonalpha components is wrote on 5 bits and the alpha component on 1 bit. For other data types, RGBA (8888) data are converted into RGBA (5551).
When image_type is equal to argb, hypermat of int8 or uint8 will give the ARGB components, hypermat of doubles will give normalized ARGB components (values between 0 and 1), matrices of int8 or uint8 where number of rows is a multiple of 4 will give the RGB components, matrices of int32 will give ARGB colors, matrices of uint32 will give ARGB colors.
 clip_state:
this field contains the
clip_state
property value for theMatplot
. It should be :"off"
this means that theMatplot
is not clipped."clipgrf"
this means that theMatplot
is clipped outside theAxes
box."on"
this means that theMatplot
is clipped outside the rectangle given by propertyclip_box
.
 clip_box:
this field is to determinate the
clip_box
property. By default its value should be an empty matrix ifclip_state
is"off"
. Other cases the vector[x,y,w,h]
(upperleft point width height) defines the portions of theMatplot
to display, howeverclip_state
property value will be changed. user_data:
this field can be use to store any scilab variable in the
Matplot
data structure, and to retreive it.
