SptFillRect()

SptFillRect(bBuffer As bTftLibParameter1, wOriginX As wTftLibParameter1, wOriginY As wTftLibParameter2, wWidth As wTftLibParameter3, wHeight As wTftLibParameter4, wColor As wTftLibParameter5), Byte

Fills a rectangular region within a sprite buffer with a solid color, while preserving the buffer’s existing width and height metadata.

bBuffer - Sprite buffer index to modify.

wOriginX - X coordinate of the bottom-left corner of the rectangle, relative to the sprite buffer.

wOriginY - Y coordinate of the bottom-left corner of the rectangle, relative to the sprite buffer.

wWidth - Width of the rectangle to fill.

wHeight - Height of the rectangle to fill.

wColor - Color value used to fill the specified area.

Return

0 – Operation completed successfully

1 – Invalid buffer index

3 – Buffer size is smaller than the specified fill area

Notes:

If the origin coordinates lie outside the buffer boundaries, no action is taken.

If the origin is valid but wOriginX + wWidth or wOriginY + wHeight exceeds the buffer dimensions, the fill area is automatically clipped to the buffer boundaries.
