Cannot get transparency on clock background. [SOLVED]

[Logansfury]

Hello everyone

Here is what I am dealing with:



Image on the left is a clock displayed with .lua. Image on the right is biohazzard sign displayed with .lua

As you can see, the clock has an obvious visible outline of the boarder and I cannot get rid of it without breaking the clock.

When I set transparency with the Edit Widget I get this:


Here is the conky code for the biohazzard image:

Code: Select all

--[[
Bleys 2024 

]]
conky.config = {
-- — Conky settings

	background = false,
	total_run_times = 0,
	no_buffers = true,	

-- — Window specifications with Background

	own_window = true,
	own_window_type = dock,
    own_window_hints = 'skip_taskbar,skip_pager,undecorated,above',
    own_window_transparent = false,
	own_window_argb_visual = true,
	own_window_argb_value = 0,
	own_window_colour = '000000', 
	
	double_buffer = true,
	minimum_width = 300, minimum_height = 263,
	alignment = 'middle_middle',
	
	gap_x = 20,
	gap_y = 20,


-- Lua Load
	lua_load = '/home/logansfury/.conky/Biohazzard/pic.lua',
	lua_draw_hook_post = 'main',		
};
conky.text = [[

]];

Here is biohazzard .lua:

Code: Select all

--[[
2024 Bleys


]]

require 'cairo'
require "imlib2"
home_path = os.getenv ('HOME')


function fDrawImage(cr,path,xx,yy,ww,hh,arc)
    cairo_save (cr)
    local img =  cairo_image_surface_create_from_png(path)
    local w_img, h_img = cairo_image_surface_get_width(img), cairo_image_surface_get_height(img)
    cairo_translate (cr, xx, yy)
    if arc then
        cairo_rotate (cr, arc)
    end
    cairo_scale (cr, ww/w_img, hh/h_img)
    cairo_set_source_surface (cr, img, -w_img/2, -h_img/2)
    cairo_paint (cr)
    cairo_surface_destroy (img)
    collectgarbage ()
    cairo_restore (cr)
end

function conky_main()
	if conky_window==nil then return end
	local cs=cairo_xlib_surface_create(conky_window.display,conky_window.drawable,conky_window.visual, conky_window.width,conky_window.height)	
	local cr=cairo_create(cs)		
	local updates=conky_parse('${updates}')
	update_num=tonumber(updates)
  
	if update_num>4 then
        fDrawImage(cr,'/home/logansfury/Pictures/bio_sm.png',150,132,300,263)
	end

   cairo_surface_destroy(cs)
   cairo_destroy(cr)
end

By comparison, here is the clock conkyrc:

Code: Select all

conky.config = {

	background = false,

	alignment = 'middle_middle',
	gap_x = 290,
	gap_y = 20,

	imlib_cache_flush_interval = 100,
	imlib_cache_size = 2048,
	text_buffer_size = 1024,

	lua_load = 'grey.lua',
	lua_draw_hook_post = 'imlib_clock eigen 200 100 100',

	update_interval = 1,

};

conky.text = [[

and the clock .lua:

Simple clock, written using imlib. Edited by Etles_Team (2016)
Make sure you've installed "imlib2" application in your system if this script doesn't work :)

To use this script in Conky, Add this command in conkyrc file before (TEXT), Example :

lua_load ~/.conky/Conky-Name/imlib_clock.lua
lua_draw_hook_pre imlib_clock theme

OR you can add this other command to load script in conkyrc after (TEXT), Example :

${lua imlib_clock theme-name 120 100 100}

--=================================== Regards, Etles_Team =====================================--

I have tried overwriting the window settings of the clock conkyrc with the biohazzard.conkyrc but while this makes the background go away, it also destroys and washes out the image.

Can anyone please help me get rid of this background outline?

Thank you for reading,

Logan

Transparency in conky is a princess! But i believe this shadow is a bug in the newer conky on Mint 21 and above..

Have you tried own_window_type = 'dock', ?

[Logansfury]

Background still outlined when set to "dock"

[trytip]

#all options for own_window_type are normal, desktop, dock, panel or override
i use own_window_type desktop
and in conky manager i use pseudo-transparent which should remove the transparent or semitransparent box

[Logansfury]

#all options for own_window_type are normal, desktop, dock, panel or override
i use own_window_type desktop
and in conky manager i use pseudo-transparent which should remove the transparent or semitransparent box

I have tried Pseudo-Transparent with window type set to both dock and desktop, the outline is still visible. Only when I set full transparency does the entire background including outline disappear, but that also transparentizes the clock face and hands.

i believe your two images are in conflict. you can only load one .lua image which should be the base of the clock. try the clock only with no other attachments. do other clocks act this way? also a few years ago from Etles_Team the odd imlib_clock.lua cause my .xsession-errors to report gigabytes of imlib errors.

This is interesting. The .lua I have displays 4 images: clock-face, hour, minute & second hands.

By comparison, the two conkys I have with .lua drawn clock hands rather than image hands, I have full proper transparency.

So the 3 images of the fancy hands is what is killing me?

Wolvrik sent me a clock I had asked him to share, and while he was at it, he sent another he thought I would like. He was right, the 2nd clock is beautiful, but most importantly, I made a dupe of its folder, renamed it, swapped out it's graphics for the grey & orange set, and it worked!!

No background, full transparency, full 100% solid display of the clock media in vivid color.

I am very very happy
