Hi,

I have something to ask about making sticker part.

This topic is related to MLCAD, LDraw.

When I tried to make sticker part, I faced a problem with Sticker Generator.

I saved 256 color BMP file from scaned real sticker image like below.

I tried to convert it to DAT file by Sticker Generator and got below result image.

When I saw this DAT file by LDview 4.1 and MLCAD 3.3, it showed like below.

I was disappointed at the result image so much.

Corresponding sticker part is here : http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/4622303i.dat

It shows very high quality like below.

It looks like not from BMP image.

Here are my questions:

1. Why couldn't I get correct DAT file by Sticker Generator? Did I neglect any important option or anything else?

2. How can I get better quality sticker rather than from BMP file?

BMP file type is a lossless format, so the poor quality is not surely due to this.

I think the problem is that you use 256 colours scale, while the bitmap support 24bit colours and alpha channel.

Hi, Thanks for comment.

But I already tried it as you said.

In case that I used 24bit color in BMP file, Sticker Generator worked like below:

It showed warning message to ask paletted bmp.

It showed incorrect preview.

It showed incorrect result file.

So I don't think that this problem came from 256 color BMP.

I think the first problem came from 256 color BMP, instead.

While the second problem could be another issue, perhaps a bug of the software.

Try making an image with a width that is a multiple of four.
