ImageUtils.makeImage(id, inpath, t, colormap, timestamp=False, label=False, scale=1, bc=None, fontsize=6, border=True, gzipped=True, fieldname=None, fontpath='/usr/share/fonts/msttcore/')

Draw morphology for one timestep

Parameters:

• id (str) – simulation identifier
• inpath (str) – path containing data files
• t (int) – time step
• outpath (str) – path to save images to
• colormap – dictionary with cell types as keys and colors (r,g,b) as values
• timestamp (bool) – add time stamp to the image
• label (bool) – add id as label to the image
• scale (number) – scaling of the image
• bc – color of cell boundaries (r,g,b)
• fontsize (int) – size of the fonts used for label and time stamp; font size will be multiplied by scale.
• border (bool) – cut of border pixels
• gzipped (bool) – data is gzipped
• fieldname (str) – name of chemical field
• fontpath (str) – path to freetype fonts

Returns:

image object

Parameters:

• field – numpy array with relative director
• sigma – numpy array with cell id’s
• scale (number) – scaling factor

Returns:

image object

• ylabel – str
• xtics – list of labels on x-axis
• ytics – list of labels on y-axis
• fontsize (int) – fontsize for labels and title
• scale (number) – scaling factor of the created picture
• border (bool) – add border to subimages
• title (str) – overall title for image
• bcolor – background color (r,g,b)
• fcolor – font color (r,g,b)
• fontpath (str) – path to freetype fonts
• delta (number) – extra space between images
