Thanks, I found the solution to the error. I needed to set the DrawingNavigator's Parent first. Your suggestion to use the DN ActualGraphic property is interesting. I wonder if there is also a way not have to use a DrawingNavigator at all, given that the zoomed image is already in a TsgImage control...

sorry to hijack this thread but I have the same problem. I have tried to print the resulting bmp to see what is going on but it is failing before that with an error on the line that assigns the picture from my TsgImage to the TsgDrawingNavigator so I can use your ActualGraphic function. The error is...

Hi Sergey, Thanks for the quick response. I figured that would be the way to do it but was hoping someone else already had code to do it or parts of it. e.g. finding parallel lines, intersection points, determining which side (outside the area) to place parallel line etc. My maths is a bit rusty her...

Hi, Can anyone assist with the maths? I have a polyline (usually closed) that needs to be grown by a specified distance perpendicular to each edge line. Think of a house plan showing the outside walls. I need to grow this polyline by adding 600mm all round for the roof eaves to get the roof footprin...

Hi, I have a TsgImage which also has an optional bmp overlay. I can print this ok using code similar to the examples. However, I also have some custom annotations drawn directly onto the canvas. These are drawn during the OnPaint event. What would be the best way to get these to print as well as the...

Mostly sorted now,

Hi all,

I need a VCL component to load a pdf file and render it to a bitmap, preferably without writing out to disk. A pdf component that exposes the canvas may well do.

Any recommendations?

Thanks,
Steve

Thanks Sergey, That has helped but I found I also needed to: Img.GetExtents; Now it all works (including the calibration) the same as when I was exporting and importing from a temporary dxf file. I've also reduced the dummy rectangle down to 4 small corner markers so they are less obtrusive. Later, ...

Hi Sergey. I've made some progress from my last problem. I found I had to export to a temporary dxf file, then import it back in. Is there a better way? I have the following 2 issues now: 1. The blank dxf isn't actually blank, so I'd like to get rid of the rectangle without losing the aspect ratio (...

Thanks Sergey. I've incorporated some of your code, but still can't see how to assign the newly created TsgDXFImage to the sgPaintBox (class TsgImage). Here's the code for opening the file. It is the case where the file is a bitmap that I am trying to resolve. It fails on the line: sgPaintBox.Pictur...

Hi Sergey, I would like to create a new blank TsgDXFImage - what is the minimum code to do this? (I don't want to loadfromfile). It can contain a rectangle of a certain size if it needs to have at least 1 entity. Also, in my sgImagePaint - I am overlaying a bmp, but I need the blank dxf to be sized ...

There doesn't seem to be a property or method to show the area of a closed polyline.

Does anyone have any code to do this?

thanks,
