AutoCad :: How To Be Able To Scale Raster Image In X And Y Axis Independently Of One Another
Aug 10, 2011
I have some issues with Raster Image lately when I wanted a scanned jpeg of 210 x 297 mm (a4 dimension) that I want to fit into a 180x220 mm rectangular box in Autocad. I have used Photoshop CS 3 to change the image size to 180x220.
However when I insert the Raster Image files, some files are automatically set to 180x220 (as expected) and others are scaled down and I have to re-scale them (reset the scale value to 1, change the x-value and the y-value is automatically changed, but on the overall it is 180x220, sometimes x is more than y or sometimes y is more than x, but within 1-3 mm)
I want to know :
1. What is the best principle or techniques of knowing/changing image dimension (mm)
2. How to be able to scale raster image in x-axis and y-axis independently of one another?
3. Remove white background to neutral background?
Mirrored blocks with annotative attributes, I know I can scale each one individually, but there are over one hundred. It would be nice to use the properties box and type in the scale. As soon as I type in the "x" scale, y and z follow! I need to put in negatives in x only.
So we've been sent a DWG file for a large site, that includes a massive aerial (TIF) image.
At this point it's too large to even work with so I'd like to scale it down (proportionally, so it will still maintain the same aspect ratio).
For simplicity sake, lets say the image is 15,000 x 15,000 and I want to scale it down to 5,000 x 5,000.
The problem is that AutoCAD seems to use that pixel size to determine the actual scale, so when I updated the new (smaller) image, it was also 3x smaller in the world.
How do I scale down the image independently of the size so it will still maintain the same scale in the CAD world? (I'm a 3D guy so this is akin to scaling down a texture, yet having the plane its projected on maintain its original scale.)
how is the import scale for a raster image determined?
I've different scanned sketches of floor plans drawn by hand to specific scales, the resize tool is not quite accurate enough for my use. Does the view scale have anything to do with it?
I have a part and I need to scale it in the Z-axis only. It is impossible for me to rework the base geometry directly.
I have made some attempts to figure out how to do this on my own but all have failed:Thicken/OffsetCopy Object + Move Bodies + Combine (wouldn’t let me create a solid with Copy Object)Rectangular Pattern + Combine (works but not the desired result. adds a constant offset to the part, not % based, humongous model size)Derived component (uniform scaling only, prefer to modify the original file for file structure reasons)
how do I scale a group of polygons in their local axis? I have seen people doing this fine in Maya.
I have attached an image that explain this clearly. It's a simple cylinder, extruded and when I scale the extruded polygons in local x axis, they get scaled in crazy different axes.
I have several pillars that I want to scale down to the same size, but I don't want to have to scale them individually or reposition them once I'm done. Is there any way to scale them all without making them move along the axis being scaled? (I should have made them instances of each other. My only problem there is that I couldn't reposition one pillar without moving the others. for future reference, is there a way to temporarily break the instance relationship so on can be edited?)
Working in 2013 Raster Design. The commands for raster tools are not working. When attempting to insert an image the following message appears:
c:program filesautodeskautocad raster design 2013aeciibui56.arx cannot find a dll or other file that it needs. Unknown command "IINSERT". Press F1 for help.
Similar messages appear when trying other commands located within the Raster Tools tab.
well i have a problem on solving an autoCAD homework . i have a pdf with the contours of the altitude of an area and i have to rasterize it as an image in AutoCAD 2006 (i put it on windows paint , then i save it as an img (jpg) ) and then i inserted it in AutoCAD. I have to georeference that image and to fix its scale. How can i do that ?
I want to draw a ellipse with the mouse trajectory,just like draw Raster Image.Then Calculate the ellipse parameters and get a Data Base Object ellipse to add in!
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.
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.
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?
Is there a way to set the raster image file to match the drawing location so when a drawing and rastor image is moved and they have the same path the raster image will be linked to the drawing?
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?
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
