Flux ArtFirst separate file changes from screen scaling
If some cells look wider than others after enlarging pixel art, do not regenerate it yet. Check the original file's actual dimensions, the last scaling method and the viewer's zoom level, then make an integer-scale comparison from the same original. Flux Art can provide pixel-style visual candidates, but a style name does not prove that an output follows a strict pixel grid. This guide covers external checks of existing raster artwork, keeping generation resolution separate from pixel-cell size.
Identify the approved pixel original
Find the source image before chat compression, web thumbnails or secondary exports, and record its pixel dimensions and file identity. If the earliest image is already a large picture with blurred transitions, first establish whether it was actually drawn on a discrete grid. Do not pick an arbitrary block width and claim to have found its original pixels. Preserve the approved original and experiment on copies so that repeated resizing does not obscure where a change began. Mark an unknown source as unknown; visual guesses cannot replace file records.
Integer scaling gives each cell an equal allocation
Suppose an original is 32 pixels wide and is enlarged to 96 pixels using nearest-neighbor scaling. Each source pixel can occupy 3 output pixels horizontally; use the same factor vertically to preserve the original proportions. At a width of 80, the factor is 2.5, so each source pixel cannot receive an equal number of whole output pixels. A nearest-neighbor result may therefore alternate between different cell widths. This is a geometric example, not a real model test or a recommended platform generation size. It applies only when the original image pixels are themselves the intended grid cells.
| Observation | Next check | Limit of the conclusion |
|---|---|---|
| Cells look uneven only in fit-to-window mode | Viewer zoom and display conditions | Do not change the original yet |
| The integer-scale copy is regular but the current copy is uneven | Actual dimensions and scale factors | Investigate non-integer resampling |
| New transition colors appear at boundaries | Algorithm and export history | A pixel-style label alone cannot justify approval |
| Horizontal scaling is normal but the image is stretched vertically | Whether both axes use the same factor | Return the proportion error for separate correction |
| No approved original can be found | Source and earliest file | Mark unknown; do not reverse-infer an original grid |
| Local checks pass but the web image is uneven | Downstream asset and display size | Inspect the version actually used separately |
Check dimensions, not just the algorithm name
Nearest-neighbor scaling generally does not blend neighboring colors, but that does not mean every target size preserves equal-width cells. Interpolation methods such as bilinear scaling blend nearby pixels. They suit some continuous-tone images but may introduce transition colors that a strict pixel-art deliverable does not allow. First decide whether the output must be a hard-edged pixel asset or merely have a pixel-style appearance. Aseprite's size command lists options including nearest, bilinear and rotSprite. Do not treat them as equivalent outputs or claim that an algorithm was used without checking the file.
Compare a reliable pixel view with fit-to-window mode
First inspect the copy in a tool that reliably displays image pixels, then compare it with fit-to-window mode. Changing the window width changes the display scale. Operating-system display scaling and device pixel ratio may also affect rendering, so a percentage shown in the interface may not fully explain every cell on screen. If the file's pixel arrangement is regular and unevenness appears only at a particular window size, record a display-condition issue. If the pixel data or a reliable pixel view is already uneven, return to file processing. A screenshot alone cannot establish a conclusion about the original file.
Build a comparison that changes only the scale
From the same approved original, make an integer-factor nearest-neighbor copy and a copy using the current delivery settings, keeping other settings identical. Compare boundary positions along a row or column with clearly alternating color blocks, then inspect diagonals, outlines and small text. If the artwork intentionally uses blocks of different widths, do not mistake design differences for scaling errors. Check only the confirmed grid unit. The table is a checklist to carry out, not a prefilled pass report. One passing patch does not establish that every cell in the image was reviewed.
Make an explicit choice when the target size is incompatible
If a destination requires fixed dimensions that cannot be reached through proportional integer scaling, approved options may include adding padding around an integer-scaled image, adjusting the container or redesigning the pixel grid. Cropping changes the visible area, padding changes the canvas and redrawing changes the artwork; obtain approval for each separately. Do not stretch one axis just to fit, or repeatedly enlarge and shrink until the preview looks pleasing. Strict game assets or icons may have further technical requirements, which should be supplied as separate acceptance specifications.
Inspect the export, not just the working canvas
Export a clearly named final file, reopen it and read its actual dimensions. Recheck proportions, cell widths, boundaries and any newly introduced disallowed transition colors. If a downstream service resizes it again, obtain and inspect the version actually used. File delivery and web presentation can pass or fail independently; do not combine their records. Aseprite's export documentation separates keeping the project from scaling an exported copy, which is useful for organizing this workflow. This guide does not promise that it can automatically repair every already-damaged pixel artwork.
Keep a reproducible scaling record
Record the source file, target dimensions, horizontal and vertical scale factors, actual algorithm, exported file and viewing conditions in the delivery package.
