If you have a file which include objects for example for EE like transistors, resistors etc and if you group them into one and then from the corner drag it to zoom in a bigger figure.
How can I make sure that these components are not zoom in only wiring changes?
The problem is that I have like 30 images with different sizes and I'm placing them in a table with many images side by side. However, if I keep the same scale then some images looks small compared to other. So I tried to scale them to get the same size. However, this make the components's sizes are also scaled up with different scale factors.
Here is an example of circuit using the bult-in shapes in Visio. As you can see the components'sizes got bigger when I scaled up the object. This is usually desired. However, in my specific case I want to keep the component's size same.
Here is the Visio file or I think you can also use any available components in Visio.

I have imported a vector image to PaintCode app and then export its Swift to code. I want to use this vector image in a small View (30x30) but since I want it to work on different devices, I need it to be size-independent.
The original size of the vector image is 512x512. When I add its class to a UIView, only a very small part of the vector image can be seen:
I need to somehow resize the image that can be fit in any size of a frame. I read somewhere, that I have to draw a frame in PaintCode app around the image, I did it but nothing changed.
Start by selecting the "Frame" option from the toolbar
Apply the frame to you canvas...
nb: If you mess up the frame DELETE IT and start again, modifying the frame can change the underlying vector, which is annoying
Apply the desired resize options. This can be confusing the first time.
I group all the elements into a single group. Select the group and on the "box" next to the coordinates of the group, change all the lines to "wiggly" lines. This allows paint code the greatest amount of flexibility when resizing the image...
Finally, change the export options. I tend to use both "Drawing" and "Image" as it provides me the greatest amount of flexibility during development

In Marks, click Size and there pops a slider where I can adjust the size of a shape. But how to accurately control the size, is there some property with numbers to accurately control it? I have two sheets to show something similar and I want to display exactly the same sized shapes.
If you want to ensure 'sizes' are the same across two worksheets, I'd suggest snapping the 'size' setting to the center on both, as this is the easiest option to select. You can then use a measure to set the size, if this is desirable, and then the difference in size will be relative on both worksheets.
There isn't a numerical value override for the size slider.
Ben is correct, there isn't yet a numerical value override for the slider. You can use parameters with Min/Max/Sum etc. and a variable to somewhat change the sizes but they have to have multiple entries per line. It is unfortunate that Tableau still doesn't get that people want both a 'relative' sizing system that uses numbers from the dataset and a 'static' sizing system that allows for shapes to be set to '11px' or something along those lines. Yes, you can control that kind of in the dashboard with a vertical and fill entire box etc; but that doesn't address the very real scenario where you want a user to be able to re-size on the fly. Just my two cents.
I ran into this today. Very annoying. Need to keep shapes the same size across all worksheets and therefore same on dashboard.
I have a set of roughly 2000 images to process, and have stumbled on a problem regarding my edges. The original images are CT Scans of a heart, which are then thresholded and sobel filtered to produce a binary image of parts of the tissue. Unfortunately the thresholding and filtering has resulted in certain images missing the 'edges' of the heart --> R&LHS you can see the gaps & further down Just a small one at the top hopefully this shows how annoying this is to do automatically
I've tried various inbuilt methods of edge detection, but the difference in size of the gaps makes it nearly impossible to do, without filling out the bits that are supposed to remain as gaps due to the sizes of the filters I use.
Is there a way of manually "connecting the dots" so to speak? It would take forever on the whole image set but seems to be my only option, or if you could suggest any other way of doing it would be cool!
I need to include many images of unknown origin in a report. I have no idea what the images might be: portrait or landscape fotos, large or small, or even something with an atypical shape, like a 400x80 logo.
I'd like to scale down images with the following rule: proportionally downscale until the larger side is 200. And resulting image shouldn't take more space than needed (i.e. 1000x600 should be downscaled to 200x120, not to 200x200), so that there are no unneeded blank margins around non-square images.
Is what I need possible with JasperReports?
EDIT:
To clarify: "real size" mode is almost what I need. However, I don't see a way to limit height of resulting image. As a result, if the image I want to print is a portrait foto (or has even larger height compared to width), generated PDF looks ugly; in this case I would prefer to somehow downscale it to a smaller width.
I solved the Problem of resizing images of various sizes to a fixed size with "RetainShape" by writing an ImageResizer, based on the idea of the ImageTransformer from https://stackoverflow.com/a/39320863/8957103 , using https://github.com/rkalla/imgscalr for scaling the image.
I need to place labels with a transparent background over a variable-content UIImage. Readability will vary significantly depending on the relationship between the color of the label's text and the color/luminosity of the area of the image displayed under the label. Since the image will be constantly changing, the color of the label's text needs to change in sync.
I have found several techniques for determining the color, perceived luminosity etc of a single pixel. However, I need to rather quickly (while a view loads) determine the rough perceived color/luminosity of an area of the UIImage under the frame of the UILabel. I presume I will also need to measure the alpha because the same color/luminosity looks different at different alpha values.
Is there a way to calculate such a value for an area? Will I be reduced to simply summing pixels? If it comes to that, is there an algorithm to accomplish this?
I've thought of two possible approaches:
Perform some "folding" operations i.e. combining pixels from one half of the area to the other half. Then repeat until I get a single value. Would this be practical? How would you logically combine pixels to average their perceived color/luminosity?
Sample a statistically significant number of pixels in the area and then combine them (somehow) to get a rough measure.
I think this problem comes up a lot these days with people being so found of customizing backgrounds. Seems like something that would be worth my time to bang out a category or class to handle this and then share it around.
What about simply outlining your text in a way that it will show on both dark and light backgrounds?
This is how it is handled in other situations where text must be displayed over a background with unknown content (for example, films with subtitles).
