As the beginning, creating prints on rectangular tiles (3068b, 3069b, 3070b etc.) or bricks (3005, 3004, 3622, 3010, 3009 etc.) using LDPatternCreator will be easy.
The templates for these regular parts are included in LDPC package from the default.
Here is the YouTube video Philo created for the tutorial.
https://www.youtube.com/watch?v=vax5vvJH_Rs
I learned LDPE first with this video about 3 years ago, and now am one of reviewers.

1) Create new project
2) Load template for the parent part
3) Load the print image and zoom/align it on the template lines
4) Trace and paint the print patterns
5) Fill the unprinted area with colour 16
6) Export as dat file
7) Check the output file with LDView
8) Edit headers with LDPartEditor or your favorite text editor
9) Submit the dat file onto our PT

Non-rectangular shape, sloped or curved surfaces would be the next steps.

or

* Add Vertex [5] (5 is the shortcut) - to create the curved sections
* Add Reference Line - helps to line them up
* Vertex Mode
* Select [1]
* Move [2] - to correct the position of the vertices if needed

Pay attention to the number of sections and keep in mind that in LDraw we simulate a full circle with just 16 faces

* Reference Line Mode - to select and delete ref lines which are no longer needed
* Add Triangle [6] with the right color - and fill in

* You need more sections on the outside, less on the inside where the red is
* Start on the outside and try to get a somehow smooth curve
* Don't worry about the rectangles right now. You'll have ti work on them again when the blue and black stripes will touch them.

(2023-03-09, 10:31)Willy Tschager Wrote: Wow! You're a quick learner. Before you move to LDPE to get a "sticker" out of your "pattern" you should refine it a bit. From what I can see the corners are rounded. This is where the LDraw primitives come into play to get a fine hires primitive substitution in renderers.

* Move-Snap 100
* Opacity 25%
* Color black
* Add primitive -> LDraw-Primitive -> Circular Disc Segment -> 1-4chrd.dat
* Click near the corner to set it. You will have to rotate it. You could actually rotate it like the oval or via the matrix - I'll show you the later.
* Primitive Mode
* Select [1] the primitive. The Transformation-Matrix in the bottom right-hand corner pops up
* Play with the values und see what it does. Note the "minus" I put to flip my prim
* After you have changed a value you will have to hit "Apply" to see the change
* Move [2] the prim into position
* Connect it with triangles to the rest

You should use prims also for the oval.

* Delete all the gray triangles connected with the white oval
* Rotate the oval so that it is horizontal. We need the length and hight for reference
* Add primitive -> Circular Disc Sector -> 4-4disc.dat
* Click on the center of your oval and add a disc
* Use the matrix to distort your disc prim 'til it looks like your oval. Presumably your x value will be 1.5, with z=0.8

I had to click "add vertex" before and it must be in vertex mode - it does not work with "select"

Quote:* Move-Snap 100

• Add primitive -> LDraw-Primitive -> Circular Disc Segment -> 1-4chrd.dat
  

(2023-03-10, 20:03)Nils Schmidt Wrote: At this point you need to add a primitive:


When you try to add a primitive and it is only adding nothing, then your LDraw library path is not correctly set up.

Click on "Options" -> "Reset LDraw Path" to relocate your LDraw library folder.
Then try it again to insert the "1-4chrd.dat" primitive:

• Add primitive -> LDraw-Primitive -> Circular Disc Segment -> 1-4chrd.dat
  

(2023-03-10, 20:33)Paweł Turalski Wrote: When I have primitive mode and "select", and add that primitive, I see the red cross. And then after clicking anywhere - nothing happens. That's why I had to use vertex mode and add vertex. Reset library did not change anything. Maybe I understand something wrong, I select the general ldraw folder

(2023-03-11, 13:18)Paweł Turalski Wrote: Ah yes, my mistake! But does it change anything?
Also thank you for this link, it was really helpful, I used the inverted 1-4ndis in one corner, because it is in two colours. That was fun to experiment with different primitive 

But the 1-4disc works too, and feels easier to control. Of course if it technically changes something, I can use 1-4chrd instead

Now I have another question - how to make the pattern smaller? When you look at the exported preview, it sticks to the edges. The sticker is always smaller than the part, so in this case it should be smaller too. I cropped the sticker from full sticker sheet and used it as background image. I cropped it o the edges of the real sticker you apply, without that margins that are left on the sheet. So the pattern is made correctly, but needs to be scaled. How?

(2023-03-23, 19:44)Paweł Turalski Wrote: It works! As flat sticker, not a printed tile. Now removing dotted area makes sense




I tried it in Ldcad and it works too, but there are problems that are not in other stickers:

It does not "snap" to the plate. The Y position of sticker is -1 and 0 for tile. If the sticker position is on 0 then it is inside the tile and not clearly visible. Other stickers snap perfectly


The pattern is visible on the oppoiste side too, but mirrored. Not on other stickers


Please note that all 3 parts are on Y=0 position

(2023-03-23, 20:15)Rene Rechthaler Wrote: Do you have a "sticker body"? Normally all stickers are 0,25 LDU thick (the print is at -0,25).

That means you need a base (at Y=0) and sides to get a solid body (everything except the printed side has color 16).

Watch out for BFC and use prims (1-4 cyli and 1-4chrd to get the rounded edges).

(2023-03-23, 21:29)Magnus Forsberg Wrote: When making a sticker it's a good idea to start on a template. This will generate a sticker backside in you file.



But this box has a square shape, not rounded corners. But it will place your surface on the correct level, in your sticker.

You keep refering to the exported file as an "ldr". That's wrong. You export and create a dat file.

(2023-03-24, 19:19)Rene Rechthaler Wrote: Hello, for the number 6415918u:

if you look some posts up, there is the whole sticker sheet, it has its own part number in the lower right corner: 10101053/6415918

and u is the 21. letter of the alphabet

so this means "Sticker 21 of the Sheet 6415918" because here all parts are numbered like the reallife part (as long it has a number).

The header is (or looks) fixed

Now I have a question - in KEYWORDS you added "Bricklink 42151stk0121, Rebrickable 10101053, Brickowl 1167942" (this is sticker 21)
How to get these numbers? Does the sticker has its own code? I only understand the rule of the sticker sheet number + letter, like "6415918u" here

(2023-03-27, 11:40)Paweł Turalski Wrote: Done! After removing the distant meters, both warnings were gone, so that was the problem. But I changed the white oval from triangles to primitives, everything works. The only question is - why?
Really, why? In previous replies I noticed a lot about primitives. Technically does it change something if I use trianges instead? Or if I understand it correctly, the goal is to use as much primitives as possible instead of triangles, right? 

This is the final result


And the new line (line 17) in text editor. No errors or warnings
