<introduction>

|
<para>When in the texture viewer you can inspect the pixel values to obtain the exact
|
|
contents of any pixel in the texture.</para>

<title>Selecting appropriate subresource</title>

<para>More details can be found in the <link xlink:href="2c540574-0b81-4a40-8119-ba0283fddf41" />
|
|
page, but the first step is to select the appropriate subresource - array element, cubemap face
|
|
or mip slice.</para>
|
|
<para>The values that are picked out of the texture are always exact values, and will not be
|
|
affected by the currently selected channels or range adaption control.</para>

|
|
<para>At any point while hovering over the texture the status bar contains the current
|
|
pixel location that the cursor is hovering over, as well as a basic colour swatch to give
|
|
some indication of where you are.</para>

<caption placement="after" lead="Hover Status Bar">The status bar showing position and colour</caption>

|

</mediaLink>
|
|
<para>When the right mouse button is pressed, the currently hovered pixel value will be displayed
|
|
with the current float precision settings - for more information on how to tune these look at
|
|
the window reference for the <link xlink:href="B1826EEE-2ED1-44E4-8202-37CD8B3FEEB5" />.</para>
|
|
<para>For depth textures the depth and stencil values will be displayed separately. The stencil
|
|
value (as with any integer formatted texture) will be displayed as an integer.</para>
|
|
<mediaLink>
|
|
<caption placement="after" lead="Picked Pixel">The value of a pixel that has been picked</caption>
|
|
<image xlink:href="RMBStatus"/>
|

</mediaLink>
|
|
<para>If the right mouse button is just clicked, the picked pixel value will remain with the same
|
|
value as the mouse moves. If you hold the right mouse button and drag, it will update as the mouse
|
|
moves to allow some amount of refinement.</para>
|
|
<para>To make fine adjustments by a single pixel at a time, it's easiest to use the arrow keys
|
|
on the keyboard. Pressing these will shift the picked location by a single pixel in each
|
|
direction.</para>

<section address="PixelContext">
|
|
<title>Pixel Context Display</title>
|
|
<content>
|
|
<para>Whenever a pixel is picked, the pixel context display is updated to surround the currently
|
|
selected pixel. This dialog is by default docked in the bottom right of the texture viewer, adjacent
|
|
to the thumbnail strip.</para>
|
|
<mediaLink>
|
|
<caption placement="after" lead="Pixel Context">The zoomed in context around the pixel currently selected</caption>
|
|
<image xlink:href="PixelContext"/>
|
|
</mediaLink>
|
|
<para>This context display shows a zoomed in view of the texture around the area that you've selected
|
|
so that it's easier to make small adjustments without zooming in and losing a sense of the whole
|
|
texture.</para>
|
|
<para>The pixel context viewer can also allow you to launch pixel debugging. Once a pixel is picked
|
|
the button below the context is activated which will launch the shader debugger. More information
|
|
about this is available: <link xlink:href="8a7568ca-6b2c-4873-b8eb-d1ad2aff9629" />.</para>
