# Canvas Plugin Guide
|
||||
|
||||
The Canvas plugin allows you to draw various shapes and text on your elements. It provides a simple yet powerful way to create custom graphics.
|
||||
|
||||
## Basic Usage
|
||||
|
||||
First, you need to get the canvas object:
|
||||
|
||||
```lua
|
||||
local main = basalt.createFrame()
|
||||
local canvas = main:getCanvas()
|
||||
```
|
||||
|
||||
## Drawing Functions
|
||||
|
||||
### Lines
|
||||
Draw a line from point (x1,y1) to (x2,y2):
|
||||
```lua
|
||||
canvas:line(1, 1, 10, 10, "*", colors.red, colors.black) -- Draws a red line
|
||||
```
|
||||
|
||||
### Rectangles
|
||||
Create rectangles with specified dimensions:
|
||||
```lua
|
||||
canvas:rect(5, 5, 10, 5, "#", colors.blue, colors.white) -- Creates a blue rectangle
|
||||
```
|
||||
|
||||
### Ellipses
|
||||
Draw ellipses/circles:
|
||||
```lua
|
||||
canvas:ellipse(10, 10, 5, 3, "@", colors.green, colors.black) -- Creates an ellipse
|
||||
```
|
||||
|
||||
### Text
|
||||
Write text at specific coordinates:
|
||||
```lua
|
||||
canvas:text(1, 1, "Hello World!", colors.yellow, colors.black)
|
||||
```
|
||||
|
||||
## Color Management
|
||||
|
||||
### Background Colors
|
||||
Set background color at specific coordinates:
|
||||
```lua
|
||||
canvas:bg(1, 1, colors.blue)
|
||||
```
|
||||
|
||||
### Foreground Colors
|
||||
Set foreground color at specific coordinates:
|
||||
```lua
|
||||
canvas:fg(1, 1, colors.white)
|
||||
```
|
||||
|
||||
## Render Types
|
||||
|
||||
The canvas plugin supports two different render types that control when the canvas commands are executed:
|
||||
|
||||
### Setting the Render Type
|
||||
```lua
|
||||
canvas:setType(type)
|
||||
```
|
||||
|
||||
Parameters:
|
||||
- `type`: String, either "pre" or "post"
|
||||
- `"pre"`: Commands are executed before the main object rendering (default)
|
||||
- `"post"`: Commands are executed after the main object rendering
|
||||
|
||||
Example:
|
||||
```lua
|
||||
-- Create a canvas that renders after the main object
|
||||
local canvas = main:addCanvas()
|
||||
canvas:setType("post")
|
||||
|
||||
-- Add commands that will now execute after main rendering
|
||||
canvas:addCommand(function()
|
||||
canvas:drawText(1, 1, "Overlay Text")
|
||||
end)
|
||||
|
||||
-- or
|
||||
canvas:line(1, 1, 10, 10, " ", colors.red, colors.green)
|
||||
```
|
||||
|
||||
Note: Changing the render type affects all subsequent commands added to the canvas. You can have multiple canvas objects with different render types on the same base object.
|
||||
|
||||
## Canvas Commands
|
||||
|
||||
Canvas commands allow you to create custom drawing operations using low-level drawing functions. Available commands are:
|
||||
- `textFg` - Set text foreground color
|
||||
- `textBg` - Set text background color
|
||||
- `drawText` - Draw text
|
||||
- `drawFg` - Draw foreground colors
|
||||
- `drawBg` - Draw background colors
|
||||
- `blit` - Draw text with foreground and background colors
|
||||
- `multiBlit` - Draw multiple blit operations
|
||||
|
||||
### Adding Commands
|
||||
|
||||
```lua
|
||||
-- Example of proper command usage
|
||||
canvas:addCommand(function()
|
||||
-- Draw red text on black background
|
||||
canvas:drawText(1, 1, "Hello")
|
||||
canvas:drawFg(1, 1, colors.red)
|
||||
canvas:drawBg(1, 1, colors.black)
|
||||
|
||||
-- Or use blit for more efficient drawing
|
||||
canvas:blit(1, 2, "Hello", "fffff", "00000") -- white on black
|
||||
end)
|
||||
```
|
||||
|
||||
### Advanced Blit Example
|
||||
|
||||
The multiBlit function allows you to render text efficiently in a rectangular area:
|
||||
|
||||
```lua
|
||||
canvas:addCommand(function()
|
||||
-- Parameters: x, y, width, height, text, fg, bg
|
||||
canvas:multiBlit(1, 1, 5, 3,
|
||||
"HelloWorld!Hello", -- text (width * height characters)
|
||||
"ffffffffff", -- fg colors (width * height characters)
|
||||
"0000000000" -- bg colors (width * height characters)
|
||||
)
|
||||
end)
|
||||
```
|
||||
|
||||
Note: Do not use drawing functions like `line`, `rect`, or `ellipse` inside commands as this will cause render queue issues. Use the low-level drawing functions instead.
