Who did use Base64 Image for Button?

By season_X · 2019-03-01

Description

global Logo_image = "...."
local ConvertClass = dotnetclass "system.convert"
local ImageClass = dotnetclass "system.drawing.image"
fn ConvertBase64StringToImage string =
(
bytearr = convertclass.FromBase64String string
memstream = dotnetobject "System.IO.MemoryStream" bytearr
DecodedImg = ImageClass.fromstream memstream
memstream.close()
DecodedImg
)
btn_image = ConvertBase64StringToImage Logo_image
button Align_Right width:45 height:45 image:#(btn_image, undefined, 1,1,1,1,1)

-----Why didn't the image show?

--First use the "Base64 encoding" developed by lonerobot in http://lonerobot.net/?p=314 to convert an image (preferential .PNG without background) to Base64 string

from mxs reference

Button UI Control
Parameters:

images:

An image-specification array for providing bitmap images for the button. If this is specified, the <caption> is ignored and the contents of the button are replaced with the bitmaps.

it expects array of bitmaps and not dotnetclass "system.drawing.image" image objects
