Commands

Here’s the listing of the available commands and their syntax:

Command & Syntax Details
image_load "file-path"; Loads an image file. The path of the file is provided via the parameter file-path (quoted string).
image_save "file-path"; Saves the image to a file. The path of the file is provided via the parameter file-path (quoted string).
   
layer_select id; Sets the active layer. The layer is identified by its zero-based position using the parameter id [0..1024].

layer_resize width height;

layer_resize width height quality;

layer_resize width height quality function;

layer_resize width height quality function option param;

Resizes the layer. For the width and width, you can either provide absolute values or percentages; percentage values must be terminated with a “%” character without spaces, e.g “33.33%”.

You have the option of specifying the quality [blocky, normal, high, custom].

If the quality is “custom”, you must specify the function [nearest_neighbour, bilinear, bicubic_cardinal, bicubic_b_spline, bicubic_bc_spline, windowed_sinc]. If the function is “windowed_sinc”, you must specify the window type via option [bartlett, blackman, blackman_harris, bohman, cosine, gauss, hamming, hann, kaiser", lanczos, parzen, rectangular, welch] and the window size via param [1..1024].

Example:
layer_resize 1024 300% custom windowed_sinc lanczos 8;

layer_set_ppi ppi;

layer_set_ppi ppi_x ppi_y;

 Updates the physical resolution of the layer in pixels per inch. You can either specify a combined value (positive integer or decimal) using ppi [1..10000] or separate values for the X and Y direction using ppi_x and ppi_y [1..10000].
layer_update_dynamic_content; Updates dynamic content such as text, linked layer data, or applet linkage data (QR codes, etc.).
layer_add_border size; Adds a border of size size [0..1024] to the image. The direction of flip is set by the parameter direction [horz, vert].
layer_set_canvas width height x_off y_off; Sets the layer’s canvas such that the new size becomes width by height pixels and the old pixels are inserted at the offset x_off, y_off.

layer_clean_alpha method #color ;

Cleans the transparent areas of the current layer. The logic used for the clean is set by the parameter method [plain, content].

layer_fill_alpha method #color;

 Applies a solid-color background to the layer. The logic used for the fill is set by the parameter method [plain, content].
   

 

You can generate script code for most commands in Chasys Draw IES by using them while running the record function.
