UI_BITMAP_LOAD Function

Syntax

Arguments

name

The name of the bitmap to create.

bitmap_data

The blob variable containing the image data.

Description

UI_BITMAP_LOAD() creates a new bitmap in memory from the data in a blob variable.

Example

Get the original color image, then extract the color data and the alpha channel data.

png_data = file.to_blob("c:\documents\Xbasic Reference\Images\toucan.png")
rgb_data = png_to_bitmap(png_data, "R")
trans_data = png_to_bitmap(png_data, "A")

Create two bitmaps from the color data and the alpha channel data.

ui_bitmap_load("rgb", rgb_data)
ui_bitmap_load("trans", trans_data)

Calculate the positions of the three images.

pixsize = ui_bitmap_info_get(rgb_data, "w,h")
xpix = valpixsize, 1, ","?
ypix = valpixsize, 2, ","?
xperin = ui_info(4)
yperin = ui_info(5)
width = xpix/xperin
height = ypix/yperin

Combine the three images.

ui_bitmap_create("combine", width, height)
stone_data = file.to_blob("C:\WINDOWS\Greenstone.bmp")
ui_bitmap_load("Stone", stone_data)
ui_bitmap_draw("combine", <<%code%
bitmap("stone", 0, 0)
bitmap_alpha("rgb", 0, 0, "trans")
%code%)

Display the three images.

Limitations

Desktop applications only.
