Using vector and raster on same drawing

[achy9]

If I switch between vector and raster tools for my drawing, what will happen when it is printed as a large-format mural?  Not sure how to set up my  project which will be printed at 8' x 32'.  I want it to have a hand-drawn feel.  Thank you.

My question is the same as above but along with does this app use CMYK

When you switch between vector and raster Persona, the app will create a new layer for that Persona's tools to work on.

Yes the app has CMYK colour options available.

Hi, achy9,

By definition, raster images will degrade as they are resampled. There is one thing to consider. At what dustance will the image be viewed. Some years ago, I worked on a project that turned a very high quality color transparency that was 4" x " inches to a banner that was 4' x 8'. I s'pose in the interim, there have been improvements, but up close the banner was quite mushy. However, it was displayed a minimum of 8' away from the viewers, so it looked pretty good.

So, on my desktop, which has significantly more memory and storage than my iPad, I just used Designer to make a 8' x 32' document at 300 dpi. I painted 1 brush stroke w. the brush at 4096 px. So the stroke was a bit larger than 1' and maybe 4' wide. Took 37 sec to draw. Not very spontaneous. The file saved w. just that 1 stroke was 258.7 Mb. Not sure how immense the final file might be if all pixel, but supposing the drawing would take hours. Assuming frequent saves.

So if you want high quality, scale that to what your hardware might handle. Cut out a section, resample it up, and print out as small piece.

Thank you! I wasn't even thinking about file size yet but I will look at that too.  This will be viewed from 20-30 feet away, so I know I can get along with a little bit of loss of clarity on backgrounds but I just don't want it to look strange with partial vector drawing and partial raster with loss of clarity.  I'll do what you suggest and make a mock drawing and print a small piece to see what it will look like.
