AutoCad :: TIFF Bitonal Raster Image
Oct 8, 2008
AutoCAD2008
In doing some more research on my "reference question" below, I found that the scanner we have at work creates a tiff image and apparently there are different types of tiffs. Our scanner creates a tiff with a "bitonal" color setting. How to convert a tiff with a "RGB" color setting to a tiff with a "bitonal" color setting. I have done some searches but have come up with very little information about the subject. I would prefer to be able to do this with autocad software if it can be done.

inserting a Tiff image into a dwg file with Raster Design 2011. I have a image scanned at 400dpi and the image is a good quality image, some of the text is small be legible. When I insert the image with the imageattch command the image seems to gain pixels therefore causing some text to become unreadable. I've used the bitonal filter but then I lose some resolution. Is it normal for the TIFF image to appear more dense when brought into an Autocad drawing? If so is there a way to adjust the image to look more like the scan?

How can I make a raster image transparent? I would like to see image #2 below image #1 by making image #1 semi-transparent. I can make one specific color in the image transparent..I am working from a scanned image in jpeg format. I would think it should be easy because any Microsoft Office program can do it. I have searched through multiple Autodesk discussion boards to no avail.

I have a problem with a drawing, containing aerial images.
If I try to plot it as PDF, using "Adobe PDF" or "PDF-Creator" as printer, I see green areas in my PDF. Here the result:
If I use the AutoCAD Printer "DWG to PDF.pc3", there is no problem. Here the result:
For the creating of PDF files I can use the AutoCAD printer, that is no problem, but I have the same Problem if i try to plot a drawing with aerial images on a Plotter (HP 1050C) or any other printer in our office.

I'm having an issue where the more I zoom into a drawing that has a raster image (a 1mb jpg) in it, regenerating times become increasingly long until the whole program just freezes. When I zoom back out, it's fine.
I've tried changing the file type, saving it with a different program, lowering the quality to Draft, zooming in on an area that the raster image wasn't in, lowering the DPI of the image, nothing works. I've spent the last two hours searching Google for a fix, found nothing. The only thing that seems to work is if I put the image on a layer and freeze it. The problem there is, I'm tracing over the image, so it being invisible makes it rather difficult to work with.

I'm still learning some of the basics in the AutoCAD Map features. Most of my work has been using a map that is connected to data. My raster image is connected to a Sid file which covers more area than I usually need to work with.
What is the best way to work with a small area at a time? I cannot seem to imageclip the connected raster image.

I have a small raster image (png) xrefed to an Autocad 2012 dwg. The image is on its own layer and the transparency of the layer is set to 60%.
When I select TPY the image displays correctly on the screen (i.e. semi-transparent). When I tick Plot transparency in the Plot dialog box and send the plot to our HP Designjet 800 the raster image prints exactly as I want (semi-transparent).
However when I use the Autodesk pdf writer (Dwg to pdf) the resulting pdf does not have the semi transparent appearance and the raster image appears in all its brilliant color even though it displays correctly (i.e. semi-transparent) in Print Preview. And, yes, I have ticked the Plot transparency box before seeing it to the pdf writer. Other autocad entities such as plines which are semi transparent are fine, its only the raster image that seems to lose its semi-transparent quality.

Is there anyway to bind a raster image to a drawing?
Everytime I bind/insert my title block the images dont bind in and also the file paths get deleted. Asked most of the drafters I know and everyone says it cant be done, which is what i think.
Normally I would use a CAD version of the Logos (for the client/architect,etc.) but sometime there isnt one available so have to use raster images.

Running AutoCAD 2004, XP Pro...I have inserted our company logo into the title block as a Raster image. The logo is png, and I have tried retaining the path and not retaining the path with the same result. After saving this as a template, I reopen as new sheet to start a drawing and the logo is now the path name.

I am having some problem with plotting Raster image.
From time to time I need to use raster image as a background such as the example in the attachment. Here you can see that the raster image is only plotting half of the image.

Is there a way to change a pdf underlay path when drawing files are moved?
Is there a way to set the pdf path to match the drawing location so when a drawing?
and pdf is moved and they have the same path the pdf will be linked to the drawing?
The same can be asked about raster image files & AutoCAD?

I'm using C3D 2013 on a 64 bit windows 7 machine. I have basejump loaded, and when I first installed it there would be a "Raster" tab in the ribbon that would allow me to resample, etc. That tab is now gone. How to get it back?
I used to click on a point to select it and a new tab would show up in the ribbon to list points, edit points, etc. That doesn't come up anymore either.

I have a a graphic image from a client to use as signage on my 3d model. In photoshop I have isolated the letters and the logo only by erasing the background. No color is in the background, not white nor black, it is transparent in Photoshop.
I saved the image as a .jpg, .tif .tga. and .bmp. Any of these raster images, when inserted into the drawing, shows the background as white. I cannot undertsand how to make it transparent so it looks like letters painted on the wall.
I have changed IMAGEFRAME set to 0 - no change, I have set properties TRANSPARENCY to YES but no change.
Am I missing a step, or does the program always show raster images in a box?

Here's the Code I have so far:
I want to iterate through the Image Dictionary and Connect into the Raster ImageDef Properties.
I want to be able to modify and fix missing Raster Images.
How to get this code sorted out.
For Each myObjID As ObjectId In myModelSpace
Dim myEnt As Entity = myObjID.GetObject(OpenMode.ForRead)
If TypeOf myEnt Is Image Then Dim myRasterImg As RasterImage
Dim myRasterImgDef As RasterImageDef 'Open The Dictionary
Dim ImgDict As ObjectId = RasterImageDef.GetImageDictionary(DatabaseIn)
For Each dictEntry In ImgDict NextEnd If

I am using a tiff file as a Raster Image Reference while drawing over it in AutoCad LT for mac. The raster file is 8200 x 5700. If I examine the autocad drawing by zooming in closely the alignment is perfect. However, when I create an A0 pdf file of the drawing there is an alignment error between the raster image and the vector drawing on the x axis. The y axis alignment is perfect.
I believe it is a scaling error since there is no visible alignment error on the left hand side of the drawing and the error increases across the drawing to the right hand side. The error is small, about 0.2% but it is clearly visible in the pdf file.
To illustrate the problem I have put a test mark on the top right hand corner of the drawing outline and the attached file shows this portion of the drawing in autocad on the left and in the pdf file on the right.
I have tried different drivers and plot settings but the error is always there.

I am using MAP3D 2013 and trying to create a raster image file for use in anther document (the document will not accept a dwg or dwf file, only a raster image).
When I use the JPGOUT (or PNGOUT or BMPOUT or TIFOUT) command I can select all of the objects and viewport; there is no problem creating the file. But when I open up the raster image, only the viewport outline and objects in paperspace have come accross; the viewport appears empty.
In MAP, the viewport is turned on and I can see everything as intended.

I've rebooted, re-installed and nothing changes the fact that when i try and insert a raster image the program locks right up.
I can go back 2009 version and have no problems inserting the same raster. The raster is a Mr.Sid format file

Each time I go to insert a raster image it opens to a directory which has no files stored in it.
I do have a handful of directories that have my image files stored, and I have gone into Options>Files>storage paths>.... and set them per specs.
Is there a way to change the default directory that the dialogue box opens, when I select- Insert>Raster Image ?
I've also gone through all the options under the Option>File tab, and likewise don't see where it'd be set. I even clicked all the plus signs, down to their respective directories, and none of them match.

Insert a Raster Image or an OLE object (like a selection from a XLS worksheet).
Explode the Raster Image/OLE object.
=> the Raster Image/OLE dissapears and the frame remains (LINE objects).
I think that these types of entities should not allow exploding.

we were working on some planning stuff, altogether more than 100ha in area. in Cad2006, I assembled 6 pieces of colored plans (jpg), each above 10 MB. I did this because scaling and aligning files this size in Photoshop is a real pain and inaccurate.. anyway, when I printed them to pdf (I did select for maximum quality in printing dialog), the lines in the image was a bit fuzzy when viewed for original size. the original ones are sharp as hell on the same scale. and I made sure I DID NOT print larger than the original. luckily the quality loss was not obvious for final use on the A1 poster. still, I wonder if anything can be done to output losslessly.
