View Full Version : How to use bitmap for title block text
19th Jan 2004, 11:23 pm
I'm updating our company titleblock,have the bitmap just need to figure out how.Its got a white background and black text.If I insert as a raster image the text the background comes with it which I dont need.How do remove the background?I think what I need to do is either trace the text outline with a polyline and then use the hatch command to add a solid hatch or maybe try and find the font and recreate the logo?Sound correct?Will take long while and not really the soultion I was hoping for.Even if I cut the text out it wont be exact as there isnt a true edge when you zoom into the font as theyre a raster iamge.Maybe I need a vector image? :?

If the background is white, why do you want to remove it? Does it show up when you print? Have you tried "clipit" from the Express Tools? It basically let's you pick a circle, rectangle, etc. and uses that to crop an image. If you clipit a couple of times, you may be able to crop out the majority of the background.

Expect best results from vector images.
If you can find the fonts to rebuild the logo, you are done.
If you can find a font that is "allmost" the same, explode the text and adjust the resulted polylines.
For only a few letters, import the bitmap, zoom in and trace a polyline to match the original image.
If none of the previous advices will work, try something else :D

I am a fan of both the vector logo and the bitmap logo. But currently i have set our logo as a bitmap as it prints out fine on our laser printer and comes out in full colour when we send dwgs as PDFs. also, as long as you have a default location, you can easy change logos as the company changes its corporate image.

I'm looking at trying to see if our graphic designers will have a vector image for me or if I can find out what font they used.I would prefer not to have the background and just have the text,either as a font or as a hatched polyline font.

...or vectorize the raster image. But this question was covered before in this forum.

Yeh this is the thread I think you mean:
Looks like it wasnt a .eps file that I needed but a .wmf file!
Have another question too:
We use color dependant plot styles at work,but my non CAD clued up company would probably prefer the logo to be a certain color.The color they require is the heaviest pen setting we have :( .Is there a way to have my logo on a layer that plots differently than it actually displays?Like for instance say the color required is blue,can I have it display as blue but actually be on say red which as a thinner pen?Would be wonderfull if I can get it to work.I could tweak the plot style pens ,but that would screw up all my previous drawings,not the answer.

Hm... good question, Hyposmurf!
Just my cheap guess: draw the logo with red to plot as you need, and draw it again with blue on a layer set to "noplot".
I admit that this is not the best solution. Probable you do not wish to use the "plot with lineweights" option.
Is this one of the situations when is prefered the use of the raster images?
*** editing ***
For the human observer the difference between colors say 170 and 172 is wery small. Both of this colors appears as blue. So you can use "allmost" the wanted color for the logo and assign the desired pen width.

Right I've managed to get the file saved as a WMF.So my next step was WMFIN the logo,but up pops the file select box,I select it and then it closes.Then nothing,doesnt ask me where to specify base point of insertion the command is finished!Whats going on?

Ah young grasshopper.........
its in your dwg, but its tiny and needs to be scaled up,plus it comes in on its own layer which 9 times out of ten is black (or colour 250) so you have to look real hard.
I had the dame problems when i first started importing wmfs from coreldraw.

Great and thanks.Thats daft though on colour black and coming in soo small,you dont even see it attached to your cursor.Mind you it didnt even allo me to change the scale or postion,is that right?

I used to import,explode,change layer,bmake then re scale the text that imported in.
be carefull on the amount of times you expode the text,as you will change it from a polyline to a huge amount of lines.
p.s, Hyposmurf, supermember, :D thats funny. I would have used forum resident myself. did u ever see that movie from the early 90,s by steven king called the lawnmower man?and in the end he becomes part of the computer, i think thats your next step from supermember :lol:
