Texture

[TurBoss]

Hi,

I'm interested on this feature and thank you for creating it.

I'm trying to load an image on FreeCAD 0.16 but it shows me an error "Error in reading the file"
the file is a grey scale image converted with the gimp

Hello TurBoss! Welcome to FreeCAD and the forum
Can you share the file, or one that shows the same behaviour?
Thanks for posting your "About FreeCAD" info, this gives a good baseline to work from

Hi,

here is the picture converted with the Gimp and Imagemagick

oh too bad seems that bmp is not allowed for attachments

the imagemagick converted one : http://i.imgur.com/jPAwcc9.png

Edit: They where bmp Imgur converted it on the fly

Hi Turboss,

I had the same problem.

In the gimp go to menu Image / mode / greyscale
and then export to bmp.

I obtain allways a 8bits greyscale image.

if I forget to do so --- I mean if I rework the greyscale image --> it turns back to RGB --> then you can play with the adanced options during export... but it does not work... then I allways got same trouble as you.

So this above is my solution maybe for you as well.

Just a few snapshops after the macro texture and the loftall Macro:
I try to get a mesh sothat I can make 3D print.

So I go from this blurred image made by hand with aid of Inkspace

With those 3 different settings one can see the difference in resolution of the ruled surface

I found this feature a very nice one.

I asked Mario for that and I am pretty sure that it will be possible to enable quick and dirty preview before doing long computation.

Thanks to Him!

Ive tryed with the gimpand krita and both fails

Hi
@TurBoss
I had no problems for the conversion and executee in FreeCAD
you must convert the image to 256 gray level and export to BMP (with Gimp)
I'll do a little tutorial to convert a file to the macro

but i have one little problem with this image
