4.5 Bug processing jpg files

Recommended Posts

Posted · 4.5 Bug processing jpg files

There appears to be a bug processing jpg files.    If I load a jpg file and leave all of the settings as the defaults it seems to behave as expected.  If I change  the value for "Base" to something that is larger than the value for "Height" it appears to get really confused.   This works fine in Cura 4.4.1.

I import a jpg picture in Cura 4.6.2, but the base and height are interpreted totally wrong. In Version 4.3.0 it was OK - as it was for many years in former versions! Something must have changed between 4.4.1 and 4.5 apparently. Please, repair this bug!

Could you please show with one or more screenshots, and explain what is wrong about it?

I imported the same picture in Cura_4.3.0 and in Cura_4.6.2.

I see now that a field has been added to the import window: Color model.

 

The import window for Cura 4.3.0 is:

Inport_4.3.0.PNG

What results in:

Resultaat_430.PNG

 

The import window for Cura 4.6.2 is:

Import_4.6.2.PNG

 

With the result:

( Cura 4.6.2 shows an error importing the same picture. )

Frustrating, I reported this bug back in March and supplied sample files and screen shots showing the good 4.4.1 version and the bad 4.5 version.  All those attachments seem to have disappeared.

The perspective on the models is so different that I still can't see what the difference is.

Does changing the color model make any difference?

Thanks for the reply, ahoeben.

You cab see the difference on the dimension indications: In the case of 4.3.0 the height is 10.1 (acceptable), for 4.6.2 the height is 2.6 (mm). The perspectives are the same for the pictures shown, but I had to include the error message, so the total picture is different.

I imported the same picture again, now for the Color Model 'Doorschijnend' (Transparant?), leaving the new field to the default 50. Now the dimension is the same as for Cura 4.3.0. The import again results in the error message. After empting the platform and reimporting, the result is identical, bit no error message appears. Closing Cura, restarting and then reimport shows the same result with - again - the error message.

 

Import using the Color Model as 'Doorschijnend'.

Give the result:

Resultaat_462_Doorschijnend.PNG

 

I hope this helps tackling the problem.

 

-> Where can I find a clarification on the new fields 'Color Model', and 'Doorschijnendheid' (Transparancy)?
