            remove default padding on jetpack compose textfield

            I want to customize TextField composable in Jetpack Compose. I am trying to achieve the result in the image below, but somehow TextField has some default paddings which i couldn't find how to change values of. I want to remove default paddings and customize it

            (The image on the right one is the result i achieved. I drew a border so that you can see it has padding, btw below that TextField are just Text composables, they aren't TextFields)

            Actually that is innate, it follows material guidelines. If you wish to disable it, an alternative could be to set the height of the TextField explicitly, and matching it with the font size of the text. That way it will only extend till the text does. Another way would be to look at the source of TextField. You could just copy the source and make modifications to meet your requirements. The former sounds like an easy fix, however, the latter is no big deal as well. It is doable, and is a recommended practice to customize behavior for your needs. Also, just as a side note, I don't think it is a good idea to disable that padding. It was added to design guidelines since it seems pretty sensible and natural to have it. Sometimes we find some designs attractive when we think about them but they aren't as good when seen implemented.

            focus:outline-none not working Tailwind CSS with Laravel
            Asked 2022-Mar-28 at 23:33

            I am using Tailwind CSS for my Laravel application, and want to remove the focus border on the input boxes. According to the documentation, focus:outline-none should achieve this, although it is not working for me and the border still appears on focus.

            It looks like I am targeting the wrong thing, as if I do focus:outline-black, I can see a black outline as well as the standard blue one on focus.

            focus:border-none also does not fix the problem.

            Remove horizontal lines with Open CV
            Asked 2022-Mar-15 at 13:22

            I am trying to remove horizontal lines from my daughter's drawings, but can't get it quite right.

            The approach I am following is creating a mask with horizontal lines (https://stackoverflow.com/a/57410471/1873521) and then removing that mask from the original (https://docs.opencv.org/3.3.1/df/d3d/tutorial_py_inpainting.html).

            As you can see in the pics below, this only partially removes the horizontal lines, and also creates a few distortions, as some of the original drawing horizontal-ish lines also end up in the mask.

            Any help improving this approach would be greatly appreciated!

            Changing overlap order of a line chart in altair

            I generate a line chart in Altair. I'd like to control which lines are "on top" of the stack of lines. In my example here, I wish for the red line to be on top (newest date) and then descend down to the yellow (oldest date) to be on the bottom.

            I tried to control this with the sort parameter of of alt.Color but regardless of sort='ascending' or sort='descending' the order of the line overlap will not change.

            How can I control this? Was hoping I can do this without sorting my source dataframe itself.

            Rasterize polygons based on maximum overlap (using R packages terra or stars)
            Asked 2022-Feb-13 at 07:20

            I have a question concerning rasterization of polygons by maximum overlap, i.e assign the value of the polygon that has the highst area overlap with the raster cell.

            The real world exercise is to rasterize polygons of soil-IDs in R, in order to produce relatively low resolution maps of soil properties as model inputs.

            The problem is that the rasterize() function of the terra package (and similar stars' st_rasterize()) assigns the cell value from the polygon that contains the cell midpoint. If a raster cell contains multiple polygons, I would rather like to select the value of the polygon (soil-ID), which has the highest aerea cover in a raster cell.

            Here is a small self-contained example that visualizes my problem, using terra.

            Please find one possible solution using terra and sf libraries.

            The idea is to convert the SpatRaster r into a SpatVector and then into an sf object in order to take advantage of the sf::st_join() function using the largest = TRUE argument. The rest of the code then consists of simply converting the sf object back into a SpatVector and then a SpatRaster using the terra::rasterize() function.

            So, please find below a reprex that details the procedure.

            how to repeat the height for grid-auto-rows
            Asked 2022-Feb-08 at 22:51

            I am trying to show only the first two rows of a CSS GRID.
            The width of the container is unknown therefore it should be responsive.
            Also the content of each box is unknown.

            My current hacky solution is to define the following two rules:

            • use an automatic height for the first two rows
            • set the height of the next 277 rows to 0 height

            grid-auto-rows: auto auto 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;

            I tried repeat() like this: grid-auto-rows: auto auto repeat(277, 0px) but unfortunately it didn't set the height to 0.

            Is there any clean way to repeat height 0?

            How to improve the HTML Table Styling that is to be converted into a PDF File

            I have a Python code that is creating HTML Tables and then turning it into a PDF file. This is the output that I am currently getting

            This image has 13 columns, I don't want that. I want to keep 5 columns but my major concern is the size of the td in my HTML files. It is too small in width and that is why, the text is also very stacked up in each td. But if you look at the other image, text is much more visible and boxes are much more bigger width wise. Moreover, it doesn't suffer from height problems either (the height of the box is in such a way that it covers the whole of the PDF Page and all the tds don't look like stretched down)

            I have tried to play around the height and width of my td in the HTML File, but unfortunately, nothing really seemed to work for me.

            What I've done here is remove the borders from the table and collapsed the space for them.

            I've then used more semantic elements for both table headings and your actual content with semantic class names. This included adding a new element for the elements you want at the bottom of the cell. Finally, the teacher and codes are floated left and right respectively.

            You can use a 2D FFT to find the general direction in which the crop is aligned (as proposed by mozway in the comments). The idea is that the general direction can be easily extracted from centred beaming rays appearing in the magnitude spectrum when the input contains many lines in the same direction. You can find more information about how it works in this previous post. It works directly with the input image, but it is better to apply the Gaussian + Canny filters.

            Here is the interesting part of the magnitude spectrum of the filtered gray image:

            The main beaming ray can be easily seen. You can extract its angle by iterating over many lines with an increasing angle and sum the magnitude values on each line as in the following figure:

            Here is the magnitude sum of each line plotted against the angle (in radian) of the line:

            Based on that, you just need to find the angle that maximize the computed sum.

            Here is the resulting code:

            Answered 2021-Dec-24 at 08:01

            I really don't think you can change the ripple color opacity because it is decided by the framework. It is handled by the RippleDrawable class for devices with lollipop and above and RippleDrawableCompat class for pre lollipop devices.

            Ripple opacity will be determined by the Android framework when available. Otherwise, this color will be overlaid on the button at a 50% opacity when button is pressed.

            From MaterialButton documentation.

            If you really want solid black color ripple , you can try creating a custom drawable with selector tag and set it as background in your button with backgroundTint as "null". However i don't recommend doing this.
