How to use the different size images based on current DPI scaling in ToolStripItem?

I need to change the image size based on DPI scaling. In my project, i'm using "ToolStripDropDownItem" with images. I'm having different size images for 100DPI and 175 DPI. In 100 DPI (12 * 12 image is using), its working fine.



In 175 DPI, i'm setting another size (24*24)image, its not working fine. It displays as shown in below image. Actually its not original image i think. ToolStrip automatically scaling the image from 100 DPI i think (I don't want it).



Is there any possibility to change the images based on DPI factor?



        topBorderToolStripMenu.ImageAlign = ContentAlignment.MiddleLeft;



        topBorderToolStripMenu.ImageScaling = ToolStripItemImageScaling.None;

        topBorderToolStripMenu.Size = new Size(225,25);

        topBorderToolStripMenu.AutoSize = false;


Please find the issue snap shot

  • Normally the constrols should be DPI-unaware (use the same size everywhere) and let the environment resize your controls. DPI awareness for WinForms can be adjusted in app.settings in newer framework versions: docs.microsoft.com/en-us/dotnet/framework/winforms/…

  • Devices don't have a "100dpi" or "200dpi" setting. Surely the unit is %, not dpi. 100% is 96 dots per inch. Bitmaps record the DPI of the device when they are created. For a photo it is based on the camera, for a bitmap that is created with a painting program it is based on the video adapter setting. At runtime the image is rescaled to ensure it gets the correct physical size. Go back to your painting program and correct the DPI of those 24x24 images. And ensure you program is dpiAware or they get rescaled twice.

  • @taffer I have enabled DPI aware using application manifest file in my project.

Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

Image
28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

Image
up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

A Topological Invariant for $pi_3(U(n))$

Image
3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
